Cyber security tips-1

 Cybersecurity tips:


1. Computers and the Internet have become commonplace in current day society. Every day these systems store, manipulate and exchange business and personal information. Cyber security is the steps taken to protect this information by preventing, detecting and responding to attempts to vandalize, steal or corrupt data. Organizations need to address cyber security for several reasons. Individuals and employees who have provided personal information to an organization have the expectation that it will be respected and appropriately protected. Organizational data also needs to be protected. Entities that partner or provide services to your organization will want assurance that their information and systems will not be put at risk when electronic transactions occur. Finally, many types of information must be safeguarded due to regulatory requirements. If your organization provides employee health benefits, operates a school or receives credit card payments then security standards such as the Health Insurance Portability & Accountability Act (HIPAA), Family Educational Rights and Privacy (FERPA), and Payment Card Industry Data Security Standards (PCI DSS) apply. It is not possible for an organization to develop a perfect cyber security plan. Rather, organizations should implement and continuously evaluate cyber security practices that protect sensitive data, while making their computers and networks a difficult target for malicious intent. The following section outlines basic best practices for cyber security in your organization.

2. Best practices for cyber security.

a. Establish policies and educate staff in cyber security principles. Educate staff on the proper use of computers and other technology devices in your organization. Define what sensitive data is and the types of sensitive data stored on your system. Clearly identify what data needs to be secured and how that protectionism accomplished. Create and implement policies describing how to handle and protect sensitive information and data. Create a culture of cyber security by establishing basic security practices for all staff, including volunteers. Promote security awareness and education in your organization.

b. Protect information, computers and networks from cyber-attacks. Install anti-virus and anti-malware software to keep computers and other technology devices free from viruses, spyware and other malicious programs. Having the latest security software, web browsers, and operating systems also help to defend against these threats. Whenever possible, anti-virus and anti-malware software should updated automatically and run in “real-time” mode to continuously monitor for and mitigate threats should they occur. In addition to real time protection, a complete anti-virus/anti-malware scan of each computer should be performed on a weekly basis.

c. Keep computer operating systems and application software up to date. Vendors that manufacture computer operating systems and application software are continuously introducing new versions of their product and/or provide patches and bug fixes when a vulnerability is identified. It’s important to keep computers and other technology devices up to date as new versions or updates are made available. Many vendors –such as Microsoft and Apple- regularly schedule release updates, but may publish a patch at any time to address a particularly serious threat. Most computer operating systems can be configured to automatically update themselves or provide notification when an update is available. Regardless of the type of operating system or application software used, new versions, patches and fixes should be updated regularly.

d. Provide firewall security for your Internet connection. It is commonplace for most organizations to have an Internet connection that is “always on” exposing computers to external threats 24 hours a day. Firewalls are critical as they help protect Internet-connected computers from these threats. Firewalls may be integrated into a router or wireless access point, provided as a service from your Internet Service Provider, or purchased separately from a firewall manufacturer. Regardless of the type, product updates should be regularly applied and administrative passwords changed when first deployed and regularly over time. Many computer operating systems have an integrated software firewall feature that should be enabled wherever possible. If staff work from home, verify that their home computer system(s) are protected by a firewall and are subject to your organization’s cyber security policies and procedures.

e. Create a mobile device action plan. Mobile devices including smartphones, pads, tablets, USB/memory sticks and mobile hard disk drives create significant data security concerns especially if they contain confidential information or can access computers or data in your internal network. Limit their use wherever possible and require users to encrypt stored data, enable password protection, and install security applications to prevent the theft of information while the device is operating, especially over a public network. Be sure to implement reporting procedures for staff to follow when mobile devices are lost or stolen.

f. Make backup copies of important business data and information. Regularly backup the data on all computers. Critical data includes –but is not limited to- word processing documents, spreadsheets, databases, human resources files, and financial information including accounts receivable/payable files. Whenever possible, backup data automatically throughout the day and execute a complete backup every night. At the minimum, perform a weekly backup of systems. Store the backup copies either offsite or in the Cloud. Data stored offsite containing personal, financial or health information must be encrypted. Regardless of the frequency in which data is backed up or where copies are kept, establish and test the process for restoring data back to the system.

g. Control physical access to your computers and create user accounts for each staff member. Prevent access or use of business computers by unauthorized individuals. Insinuations where computer monitors display sensitive data and may be inadvertently viewed, the use of a privacy screen or re-positioning the monitor is suggested. Enable screen savers wherever possible and require a password to unlock the computer. Laptops can be particularly easy targets for theft or can be lost, so physically secure them when unattended. Make sure a separate user account is created for each staff member and require the use of strong passwords. Administrative-level access should be restricted to key personnel only.

h. Secure wireless networks. If you have a Wi-Fi network in your workplace, make sure transmissions are secure and encrypted using the most up-to-date standards. Ensure that administrative access to the router is protected with a strong password. If your organization provides guest Wi-Fi services, ensure that the guest Wi-Fi network is completely isolated from your workplace Wi-Fi network.

i. Limit access to data and information; authority to install software. Limit –wherever possible- the circumstances that provide any one employee access to all data systems. Rather, determine the requirements for each staff persons ‘specific job function and limit their access to specific systems based on those requirements. Staff should not be able to install any software without permission. Consider the use of content monitoring and filtering systems for those computers that access the Internet.

j. Passwords and authentication. Require staff to use unique passwords and change passwords minimally every three months. Minimally a 6 to 8 digit mix of upper and lower case letters, numbers and special characters is best. Consider implementing multi-factor authentication that requires additional information beyond a password to gain entry. Check with your business partners that handle sensitive data -especially financial institutions- to see if they offer multi-factor authentication for your account.

k. Don’t forget embedded systems and other often missed data sources. Many organizations have dedicated computers that are used to monitor and control on premise systems such as heating and cooling, lighting, security and telephones. These computers can operate autonomously or by personnel at a remote location and are usually connected via the Internet. Wherever possible, these systems should be completely isolated from other computers in your organization, and, if available, using a separate Internet connection. If it’s not possible to completely isolate these devices, they should then be electronically quarantined from other computers and devices to prevent access to secure data or the introduction of viruses or malware. Devices such as copiers, printers, scanners and fax machines are sometimes equipped with internal memory or hard disk drives. Ensure that any internal storage is adequately erased when retiring these devices from active service.

l. Payment Cards Organizations that accept credit card payments must keep customer data safe. Wherever possible use a third party institution to capture and process credit card data. If credit cards are processed internally, keep only the information absolutely needed, securely disposing of the rest. Carefully control employee access to payment systems and electrically isolate computers that process payments from other organizational computers. Computers that process credit card payment should be restricted from surfing the Internet.

General Computer usage – Best practices

a) Use account with limited privileges on systems and avoid accessing with administrator privileges for day-to-day usage.

b) Keep Operating System, Application software and Anti-Virus software updated by applying the latest service packs and patches.

c) Backup of important files at regular intervals.

d) Do not leave system unattended. Log out of or lock your computer when stepping away, even for a moment

e) Supervise maintenance or rectification of faults in the system by service engineers.

f) Do not download unfamiliar software off the Internet.

g) Remove unnecessary programs or services from computer: Uninstall any software and services you do not need

h) Restrict remote access. If file sharing is not required in your day-to-day work, disable file and print sharing.

i) Treat sensitive data very carefully.

j) Remove data securely: Remove files or data you no longer need to prevent unauthorized access to them. Merely deleting sensitive material is not sufficient, as it does not actually remove the data from your system

k) If your networking devices are not using IPv6, disable IPv6from computer.

l) Always maintain a redundant power supply

m) Use system’s screen locking functionality to protect against physical access, such as a screen saver that won’t deactivate without a password, or just log out of everything so any one that wants access has to log in again.

n) The systems should be placed in a room which is dust free and has a good ventilation to avoid overheating of CPU.

o) Do not plug the computer directly to the wall outlet as power surges may damage computer. Instead use a genuine surge protector to plug a computer.

p) Don’t eat food or drink near the PC.

q) There should be no magnets near to your PC.

r) Scan all the files after you download whether from web sites or links received from e-mails.   General Internet Browsing – Best Practice.

a) Always use updated anti-virus, Operating System and applications and browser.

b) Use a web browser with sandboxing capability (like Google chrome, safari, etc.). Sandboxing usually contains malwareduring execution.

c) Download software from trusted source only.

d) Be wary of storing personal information on Internet.

e) Do not store any information you want to protect on any device that connects to the Internet.

f) Verify those you correspond with. It is easy for people to fake identities over the Internet.

g) Make a habit of clearing history from the browser after each logout sessions.

h) Delete Windows “Temp” and “Temporary Internet “files” regularly.

i) Avoid all cloud services (Dropbox, iCloud, Evernote, etc) that are based outside India.

j) Avoid using services that require location information.

k) Remember search engines track your search history and build profiles on you to serve you personalised results based on your search history.

l) Be conscious of what you are clicking on/downloading.

m) Some pop-ups have what appears to be a close button, but will actually try to install spyware when you click on it.

n) Remember that things on the internet are rarely free. “Free” Screensavers, etc. generally contain Malware.   

o) Be wary of free downloadable software - There are many sites that offer customized toolbars or other features that appeal to users, which are likely to have backdoors.

p) Avoid Internet access through public Wi-Fi.

q) Never exchange home and office work related contents.

r) Avoid posting of photos with GPS coordinates.

s) Don't respond to email, instant messages (IM), texts, phone calls, etc., asking you for your password.

t) Only click on links from trusted sources. Never click on a mystery link unless you have a way to independently verify that it is safe. This includes tiny URLs.

u) Be extremely careful with file sharing software. File sharing opens your computer to the risk of malicious files and attackers. Also, if you share copyrighted files, you risk serious legal consequences.   | 5Malware defense

a) Always set automatic updates for Operating System, Ant-virus and Applications. (My Computer -> properties ->automatic updates -> select Automatic and time)

b) Enable hidden file & system file view to find any unusual or hidden files. (My computer -> tools -> folder options -> view-> select enabled with “Show hidden file and folders” option and disable “Hide protected operating system files”)c) Turn off auto play(Win XP: Start -> Run -> type gpedit.msc -> Computer Configuration -> Administrative Templates -> System ->Double Click at Turn off Auto play -> Select Enabled -> Select “Turn off Auto play on:” to “All drives” and Click OK. Windows Vista/7 :- Start -> Run -> type gpedit. msc ->Computer Configurations -> Administrative Templates ->Windows Components - > Select “AutoPlay Policies” ->Double Click at “Turn off Auto play” -> Select Enabled -> Set“Turn off Auto play on:” to “All drives” and Click OK.)d) Type: dir %temp% in “run” and delete all entries after opening any suspicious attachments.

e) Type cmd in run and type netstat –na. Checkout foreign Established connection and IP addresses. Check the IPaddress for its ownership.

f) Type “msconfig” in “run” and check for any unusual executable running automatically.   

g) Check Network icon (for packets received and sent) / ADSL lights for data in non-browsing mode. Check data usage pattern in Mobile. If the outgoing is unusually high, then it is very likely that the system is compromised.

h) Type “ipconfig/displaydns” in command prompt and lookout for any URLs which you have not accessed recently.

i) Always be cautious while opening attachments even from the known sources. Try to use non-native applications for opening attachments. Example for word document use, WordPad to open the attachment.

j) When in doubt, better to format the Internet connected computer rather than doing some “patch works”.What is a Malware?Malware (Malicious Software) is software designed to infiltrate a computer system without the owner’s informed consent for a malicious intent. Examples of Malware include Viruses, Trojans, Worms, Key loggers, Backdoors, Root kits, Spyware, Crimeware, Adware, etc.   | 7Removable Information Storage Media Removable Information Storage Media (RISM) means any device which is capable of storing electronic information in any form. Device or media that is readable and/or writeable by the end-user and is able to be moved from computer to computer without modification to the computer. For example CDR (multi sessions), CD-RW, DVD-RW, BluRay Disk, MOD, USB Storage devices (Pen Drives, Media Cards, etc.), MP3Players, MP4 Players, Smart Phones, Digital Camera, Watches with memory, Various types of Memory cards, Internet Data Card, External Hard Disk, or any other gadget having memory space and could be connected to a system through USB or COMor any other ports or device connected through Network Share falls under Removable Information Storage Media.

a) Damaged / faulty RISM should never be handed over to outsiders / manufacturer for repair.

b) Sensitive information should be stored on removable media only when required in the cases of assigned duties.

c) All media must be stored in a safe, secure environment. d) All media must be handled with care and it must be ensured that it is not kept near magnetic material and not exposed to extreme heat or pollution;

e) The computers should be enabled with “Show hidden file and folders” option and “Hide protected operating system files” should be disabled to view hidden malicious files in USB storage devices.   

f) Make sure there is no hidden file and folders present in the Media. g) Autorun / Autoplay feature should be disabled in all the computers.

h) Avoid Baiting. (Someone gives you a USB drive or other electronic media that is preloaded with malware in the hope you will use the device and enable them to hack your computer). Do not use any electronic storage device unless you know its origin is legitimate and safe.

i) Scan all electronic media for Malware before use smart device Smart device is a device having any of the features like computation power, Internet access, storage capability, camera, recordings, GPS, etc. Smart phone, Tablets, etc. falls under this category. Most of the Smart Phones and Tablets (Tabs) are having equal computing power of a normal Desktop / Laptop systems. These gadgets are capable of delivering many services on Video, Voice, GPS and other computational apps like any other computer. Therefore, all cyber security issues related to computers are also applicable to these devices. Following are some of the security concerns of Smart devices:

I. These are equally vulnerable to malware attacks and data leakages as ordinary Internet connected computers.

II. More application, features and service are available on Smart device for exploits than ordinary feature phones.

III. These gadgets are known to be used for bugging (audio and video), monitoring call details, contents, SMS monitoring, sending malicious SMS, Emails, spoofing, and other malicious activities without the knowledge of the user. Android and IOS platform based Smart Phones and Tabs are known to have multiple vulnerabilities, which are being widely exploited by the attackers and adversaries

a) Smart device must not be used for sensitive telephonic conversation. The Wi-Fi and blue-tooth should be kept inturned-off mode.

b) A low-end basic mobile phone without camera / internet /Wi-Fi may be carried for sensitive voice conversation and contact details.

c) Internet connection in the Smart device will normally be keptin off-mode and it will be made 'on' on need basis to access internet.

d) No free Apps should be loaded in the Smart device.

e) During repairs, do not leave Smart device unattended to deny the possibility of installation of malware.

f) Relevant anti-virus software should be installed in the smart device.

g) If the Smart device gets de-activated for any reason for few hours / one day, the service provider should be contacted immediately to ascertain the reason for de-activation.

h) If the battery gets unusually discharged very fast or device gets heated up without any user activity, then it is very likelysome malicious traffic is consuming battery.

i) Free Wi-Fi should not be used at public places such as Airport. Turn off blue-tooth and Wi-Fi when use of the same is not required for operational purposes. Even when the same is in use, set default blue-tooth / Wi-Fi configuration to"non-discoverable".

j) Compromised smart device should not be connected with computer even for the purpose of charging.

k) Turn off the applications which are not needed

l) When device is idle, it should get locked and require a password / pin or swipe pattern. Set the device to lock in relatively short time.

m) Don't reply or click on link on SMS or messages sent by strangers.

n) Don't jail-break your device as jail-breaking removes the restrictions on which apps can be installed or not installed. This removes the protection set by the company.

o) Watch for unauthorised GPRS/data connection during idle mode of the Smart device.

p) Check the memory frequently if any unusual data is stored there. Malware stores temporarily, the data collected in the memory of the phone till the same is sent to the destination.

q) Suitable non-transparent tape/sticker may be applied toblock the camera view.

r) Think before you click, download, forward, or open. Before responding, registering, downloading or providing information, get the facts. No matter how tempting the text, image, or application is, if the download isn’t from legitimate app store or the site of a trusted company, doesn’t engage with the message.

s) Understand the terms of use. Some applications claim extensive rights to accessing and leveraging your personal information. If the app requires more access to your account and/or device than is needed to run the service, do not continue. In addition, be aware that terms can change overtime. Review your terms of use often.

t) Be cautious with public Wi-Fi. Many Smartphone users use free Wi-Fi hotspots to access data (and keep their phone plan costs down). There are numerous threats associated with WiFi hotspots. To be safe, avoid logging into accounts, especially financial accounts, when using public wireless networks.

u) Disable Bluetooth and Near Field Communication (NFC) capabilities when not in use. Capabilities such as Bluetoothand NFC can provide ease and convenience in using yourSmartphone. They can also provide an easy way for a nearby, unauthorized user to gain access to your data. Turn thesefeatures off when they are not required.

v) Enable encryption. Enabling encryption on your Smart phone is one of the best ways to safeguard information stored onthe device, thwarting unauthorized access.

w) Securely dispose of your device. With the constant changes and upgrades in the Smartphone market, many are upgrading their devices on a regular basis. It is important that you wipe the information from your Smartphone before disposal. Additionally, make sure any SD cards are removed and erased. If you are not redeploying the SIM card to an other device, then make sure your personal information stored on the SIM card is erased or destroyed. Checklist for Secure Android Device There are many ways to make Android device is safe and secure. A few of these are listed here:

1. Implementing basic security (screen security): Users can choose from the standard device PIN, password, pattern lock,   | 13face unlock and swipe (swipe is not a secure method). Screen lock can be set from settings > screen security > screen lock.

2. SIM PIN: users should consider setting up a SIM PIN. With this option enabled, the device will ask for the SIM PIN every time it boots up.

3. Encryption: Android 2.3.4 and later versions support device encryption. Though this is a must-have security, most device manufacturers choose to ignore it in their customized Android version. In case this feature is not available, users can use external apps such as Secret Space Encrypt or (SSE), Encryption Manager, etc.

4. Passwords: Passwords should not be made visible. Users should make sure that this feature remains disabled at all times.

5. Multiple user accounts: Tablets running on Android 4.2 +(Jellybean) provide an option to create separate user profiles for different users. This is helpful if the device is being shared by multiple family members. This feature can be found under Settings > device > users.

6. Device Administration: this section provides two features, ‘Device Administrators’ and ‘Unknown Sources’. Device Administrators are apps that can control certain features of the device. For example, when an anti-virus app is installed, it becomes a device administrator. It can erase all data on the device, set password rules, etc. on the user’s behalf. Often, these apps provide an option for users to perform these tasks remotely and hence, they need to act as device administrators.   The ‘Unknown Sources’ feature allows the user to side load apps or install apps provided by a third party app Store. Apps installed via this mode might contain some malicious code, which could pose a risk to the user’s data. This option should remain disabled at all times except for development purposes.

7. Mobile Security Suite: Installing a mobile security suite is a must. All the leading anti-virus companies provide a mobile version of their product. A mobile security suite provides wide variety of features along with an anti-virus.

8. Device backup: Users should regularly back up the data on their device. By default Android provides an option to back up the configuration and settings. This is available under settings >Personal > Backup & Reset. However, it does not back up data stored on the device. Device data can be backed up either by using the desktop software suite for the device or via third party apps.

9. Mobile Device Management: Many users bring their device and connect the same to their organization network. Leading to data leakage and other security compromise. To counter such risks, MDM solutions (Mobile Device Management) needs to be deployed by the organizations.

10. Application Permission: No apps should be allowed to access the device resources without the consent of the user. Use should refrain from installing apps that look suspicious and asks for other resources for accessing.   

11. Application Locks : If a device is changing hands, users might want to protect their personal data (SMS, Pictures, Emails, etc.)from prying eyes. An application lock is an answer to this problem. By installing apps users can put a password on apps that store personal data. Once implemented, a password protected app will ask the user for a PIN before launching.

12. Transaction Passwords: Users can set transaction passwords for selected App Stores.

13. Rooting Device: Android, ROMs shipped with devices; do not provide root (super user privilege) access, by default. While many users do not require root privileges on their device, advanced users and developers often like to experiment with their device.   

Social Networking

a) Do not store any information you want to protect on any device that connects to the Internet.

b) Always use high security settings on social networking sites, and be very limited in the personal information you share. Monitor what others are posting about you on their online discussions

c) Use anti-virus and firewall software. Keep them and your browser, and operating systems patched and updated.

d) Change your passwords periodically, and do not reuse old passwords. Do not use the same password for more than one system or service. For example, if someone obtains the password for your email, they can access your online banking information with the same password.

e) Do not post anything that might embarrass you later, or that you don’t want strangers to know.

f) Do not automatically download, or respond to content on a website or in an email. Do not click on links in email messages claiming to be from a social networking site. Instead go to the site directly to retrieve messages.

g) Only install applications or software that come from trusted, well-known sites. “Free” software may come with malware. Verify what information applications will be able to access prior to enabling them. Once installed, keep it updated

h) Avoid accessing your personal accounts from public computers or through public Wi-Fi spots.

i) Disable Global Position System (GPS) encoding. Many digital cameras encode the GPS location of a photo when it is taken.  If that photo is uploaded to a site, so are the GPS coordinates, which will let people know that exact location.

j) Whenever possible, encrypt communications with websites. It may be a feature (like HTTPS site rather than HTTP site)social network sites allow you to enable.

k) Beware of unsolicited contacts from individuals in person, on the telephone, or on the Internet who are seeking corporate or personal data.

l) Monitor your bank statements, balances, and credit reports.

m) Do not share usernames, passwords, credit cards, bank information, salaries, computer network details, security clearances, home and office physical security and logistics, capabilities and limitations of work systems, or schedules and travel itineraries.

n) No legitimate service or network administrator will ask you for your password.

o) Do not provide information about yourself that will allow others to answer your security questions—such as when using “I forgot my password” feature.

p) Be thoughtful and limit personal information you share such as job titles, locations, hobbies, likes and dislikes, or names and details of family members, friends, and co-workers.

q) Verify those you correspond with. It is easy for people to fake identities over the Internet.

r) Do not click advertisement shown in the social web   registering an Account

a) Use a strong password different from the passwords you use to access other sites.

b) If you are asked to provide security questions, use information that others would not know about you.

c) Never provide a work-associated email to a social network, especially when signing up. Consider creating a new email address strictly to connect with your social networking profile(s).

d) Do not use your real name

e) Provide only information that is necessary or that you feel comfortable providing. When in doubt, err on the side of providing less information.

f) During the registration process, social networks often solicit anew user to provide an email account password so the social network can access the user’s email address book. The social network promises to connect the new user with others they may already know on the network. To be safe, don’t provide this information at all.  Email Communication

a) Auto save of password should not be enabled.

b) Users must check their last login details while accessing the email account.

c) Use of encryption and digital signature certificate (DSC) maybe considered for mails deemed necessary.

d) Email IDs should have a strong password (at least 13 characters with alpha numeric and special characters)e) Once in every 30 days the email passwords should be changed.

f) Logout properly from mail accounts.

g) Before opening any attachment, the same should be scanned through an updated anti-virus for malicious contents.

h) Do not keep mails in Inbox, sent box, draft, etc. which are no longer required.

i) User should type the complete URL in the browser instead of clinking links from other sources.

j) Before accepting the SSL certificate, the user should verify the authenticity of the certificate.

k) Make a habit of clearing history from the browser after each logout sessions.

l) Do not open / forward / reply to suspicious E Mail.

m) Do not click any URLs mentioned in the body of the E Mail text.

n) Be cautious of Tiny URLs in Email contents.

o) Do not open attachment having extension EXE, DLL, VBS, U64, SHS, PIF , SCR   | 20Typical example .txt.exe , .doc. exe.

p) Some malicious program starts executing as soon as they appear on the Outlook Express preview pane. Disable that option (view -> layout -> uncheck “show preview pane”)q) Don't open unsolicited or unexpected attachments. If you can’t verify an attachment is legitimate, delete it.

r) Don't log in to web sites or online applications unless the login    is secure (HTTPS).

s) Don't enter personal or sensitive information online unless you are using a trusted, secure web. Instant Messaging (IM) Instant Messaging networks provide the ability to not only transfer text messages, but also the transfer of files. Consequently, IM can transfer Malware and other programs. Many IM allows peer-to-peer file sharing, a malware can configure the IM client to share all files on the system with full access to everyone. Hackers can impersonate other users in many different ways. The most frequently used attack is simply stealing the account information of an unsuspecting user.

a) Careful when creating a screen name. Each IM programs asks you to create a screen name. Screen name should not provide or allude to personal information. Use a nick name instead of full name.

b) Never provide sensitive personal information. Do not share credit card numbers/ passwords. Etc. over IM.

c) Create a barrier against unwanted IM. Do not list your name or email address in public areas or to strangers.

d) Only communicate with people who are on your contact lists. If you decide to meet a stranger that you know only from IM communication, take appropriate safety precautions. For example do not meet that person alone, take a friend or colleague with you. Always meet and stay in public place such as café or other places.

e) Never open pictures, download files or click links in messages from people you do not know.   

f) Do not send personal or private IM at work.

g) If you uses a public computer, do not select the feature allows you to log on automatically. People who use that computer after you may be able to see and use your screenname to log on.   | 23Home Devices – Wi-Fi, ADSL Routers

a) All ADSL Broadband routers should be adequately secured.

b) Disable web and telnet services from outside network.

c) Change the default passwords of all the network devices.

d) Turn off the Network during extended periods of non-Use.

e) Disable DHCP service

f) Try to use your ISP DNS rather than open DNS IP addresses

g) Always configure ISP provided DNS IP address in computer rather than automatically obtaining the same from ADSL device.

h) If update option is available in the ADSL device, update the firmware from the legitimate vendor’s web site.

Wi-Fi Device

i) Information/Data on the Wi-Fi Network should always be in the encrypted form.

j) Do not connect the access point directly to the wired network. As there is a chance of compromised wireless client in turn effecting the systems in the wired network, firewall and an antivirus gateway should be placed between the access point and the wired network

k) In order to allow authorized users to connect to the access point, wireless clients should be provided access based on MAC address.

l) Do not auto-Connect to open Wi-Fi Networks.

m) Do not use WEP encryption use WPA2 or higher graded encryption   

n) Change your SSID (Wireless Network Name)o) Turn off SSID broadcasting.

p) Change the default passwords while configuring the access point.

q) When the number of users accessing the access point is less, it is recommended to disable the DHCP service. As this may make the attackers easy, to connect to the network once they get associated with the access point.

r) Update the firmware of access point. It will reduce the number of security loop holes in the access point.Multi Functional Peripherals (MFP, Fax-Printer-Scanner Photocopies with hard disk / solid state disk

a) If possible, disable the option of saving contents in the hard disk of the MFP.

b) Set up devices to perform regular overwrites (Wiping) with a pattern more frequently. In some environments that may mean overwriting the disk after any content is printed, scanned, faxed, and copied.

c) Encrypt the data on the disk if that function is available.

d) Regularly check FAX reports in MFP.

e) Do not connect MFP to telephone line, if the MFP with FAXis to be connected to a sensitive computer.   mart TV, Refrigerator, Washing Machine, Gaming Console etc.

a. Always protect your devices with a password.

b. Change the default password of the smart devices (IOT devices)

c. Update software.

d. Do your research: Investigate the data sharing and privacy policies of the company selling the product.

e. Browse with caution. Smart TVs are every bit as susceptible to hacking as your home computer. What is Internet of Things (IOT)?It refers to uniquely identifiable objects and their virtual representations in an Internet-like structure on standard communication protocol. Each person and thing has a locatable, addressable, and readable counterpart on the Internet. Internet connected household devices with the potential to be turned in the spy tools.   

Password – Best Practices

a) Passwords must be changed at regular intervals.

b) Always use different passwords for different accounts.

c) Do not share passwords with anyone.

d) All passwords are to be treated as sensitive.

e) Passwords should never be written down or stored on-line without encryption.

f) Do not reveal a password in email, chat, or other electronic communication.

g) Do not reveal a password on questionnaires or security forms

h) Always decline the use of the "Remember Password" feature of applications

i) All users should be aware of how to select strong passwords.

j) Strong passwords contain combination of lower case characters, upper case characters, numbers, “Special” characters (e.g. @#$%^&*()_+|~-=\`{}[]:";'<>/ etc).

k) Contain at least thirteen alphanumeric characters (except in the case of BIOS, if the same is not possible).

l) Weak passwords have the following characteristics:

I. The password contains less than thirteen characters

II. The password is a word found in a dictionary (English or foreign)

III. The password is a common usage word such as: Names of family, pets, friends, colleagues, Movie /Novel / Comics characters, etc.

1. Use two-step verification whenever possible

2. Strong password recommendations:

• Longer passwords are always better. Aim for at least 14 characters

• Choose unusual phrases that are easy for you to remember that include numbers and symbols

• Never use the same password for multiple accounts

• For best results, use a password manager to create and store passwords.

3. Bad actors are constantly looking for opportunitiesin unpatched software. Keep your software up todate-it’s one of the most effective security toolsyou have. Better yet, enable automatic updates, soyou never have to think about it.

4. When using a public computer or any device that is not your own,another user may be able to access your data and accounts. Before signing off, make sure you:

• Disable any options to “save passwords”

• Log out of your accounts when finished

• Delete cookies, cache and browsing history


Types of Cyber Attacks:

A cyber-attack is an exploitation of computer systems and networks. It uses malicious code to alter computer code, logic or data and lead to cybercrimes, such as information and identity theft. Cyber-attacks can be classified into the following categories:

1) Web-based attacks.

2) System-based attacks: Web-based attacks these are the attacks which occur on a website or web applications. Some of the important web-based attacks are as follows

1. Injection attacks: It is the attack in which some data will be injected into a web application to manipulate the application and fetch the required information. Example- SQL Injection, code Injection, log Injection, XML Injection etc.

2. DNS Spoofing: DNS Spoofing is a type of computer security hacking. Whereby a data is introduced into a DNS resolver's cache causing the name server to return an incorrect IP address, diverting traffic to the attacker’s computer or any other computer. The DNS spoofing attacks can go on for a long period of time without being detected and can cause serious security issues.

3. Session Hijacking: It is a security attack on a user session over a protected network. Web applications create cookies to store the state and user sessions. By stealing the cookies, an attacker can have access to all of the user data.

4. Phishing: Phishing is a type of attack which attempts to steal sensitive information like user login credentials and credit card number. It occurs when an attacker is masquerading as a trustworthy entity in electronic communication.

5. Brute force: It is a type of attack which uses a trial and error method. This attack generates a large number of guesses and validates them to obtain actual data like user password and personal identification number. This attack may be used by criminals to crack encrypted data, or by security, analysts to test an organization's network security.

6. Denial of Service: It is an attack which meant to make a server or network resource unavailable to the users. It accomplishes this by flooding the target with traffic or sending it information that triggers a crash. It uses the single system and single internet connection to attack a server. It can be classified into the following Volume-based attacks- Its goal is to saturate the bandwidth of the attacked site, and is measured in bit per second. Protocol attacks- It consumes actual server resources, and is measured in a packet. Application layer attacks- Its goal is to crash the web server and is measured in request per second.

7. Dictionary attacks : This type of attack stored the list of a commonly used password and validated them to get original password.

8. URL Interpretation: It is a type of attack where we can change the certain parts of a URL, and one can make aweb server to deliver web pages for which he is not authorized to browse.

9. File Inclusion attacks: It is a type of attack that allows an attacker to access unauthorized or essential files which is available on the web server or to execute malicious files on the web server by making use of the include functionality.

10. Man in the middle attacks It is a type of attack that allows an attacker to intercepts the connection between client and server and acts as a bridge between them. Due to this, an attacker will be able to read, insert and modify the data in the intercepted connection. System-based attacks These are the attacks which are intended to compromise a computer or a computer network. Some of the important system-based attacks are as follows

1. Virus: It is a type of malicious software program that spread throughout the computer files without the knowledge of a user. It is a self-replicating malicious computer program that replicates by inserting copies of itself into other computer programs when executed. It can also execute instructions that cause harm to the system.

2. Worm: It is a type of malware whose primary function is to replicate itself to spread to uninfected computers. It works same as the computer virus. Worms often originate from email attachments that appear to be from trusted senders.

3. Trojan horse: It is a malicious program that occurs unexpected changes to computer setting and unusual activity, even when the computer should be idle. It misleads the user of its true intent. It appears to be a normal application but when opened/executed some malicious code will run in the background.

4. Back doors: It is a method that bypasses the normal authentication process. A developer may create a back door so that an application or operating system can be accessed for troubleshooting or other purposes.5. Bots A bot (short for "robot") is an automated process that interacts with other network services. Some bots program run automatically, while others only execute commands when they receive specific input. Common examples of bots program are the crawler, chatroom bots, and malicious bots.
