45 Killer Security Tips to Follow on Computer Security Day

30th November is observed as Computer Security Day all over the world.On this important day, we have lined out an exhaustive list of some of the best security tips on how to keep your digital lives safe, secure, and hackproof. So, let’s get cracking!

  • While revealing any personal or financial information on the Internet, ensure that the website’s URL begins with ‘https’ and is accompanied by a padlock symbol. These two elements indicate that you are on a secure website and that your information is safe.
  • While using free, unsecured WiFi networks or public cyber cafes, never shop or bank online, or login into online accounts.
  • Always go for long, unique, and hard-to-guess passwords. Keep different passwords for different online accounts.
  • Use Secure Browsing for your Facebook account.
  • Don’t bother selecting options that say ‘Keep me logged in’ or ‘Remember me’ on websites, especially when you are on public computers.
  • Prefer keeping a secondary email address for using it on websites that require you to share certain personal information. Also,  use your primary email address to stay in touch with people you know or are acquainted with.
  • Avoid using your official email address for social media sites or any other websites other than that of your organization.
  • For sites related to social media, music downloads, file sharing, etc., use an email address that you do not use for important communications such as those related to your bank, income tax, medical appointments, and the like.
  • Tighten your privacy settings on Facebook so that only your friends are notified about your activity.
  • While choosing a password, ensure that you are not using any kind of personal information such as your name, date of birth, address, pet’s name, street name and so on.

  • If you receive any emails that ask you for your personal or banking information, delete them straightaway. Exercise caution against links or attachments in unexpected or unsolicited emails. It is wise to verify any such communication with the sender first, before responding to them.
  • If there is any online account of yours which you are not using for a long time, have it removed or deactivated.
  • It is wise not to make your photos or videos public on the Internet. Keep them visible only to people you know personally.
  • Never respond to pop-up advertisements that may come up on your screen, no matter how inviting or genuine they may look. The safest way to close such pop-ups is from the task manager; press Alt+Ctrl+Delete.
  • Before downloading and installing any kind of free software, do a quick research on the software and the website hosting it. Reading user reviews about the same is also important.
  • Do not visit websites that you are not fully aware of or those that can be accessed from emails or mobile messages.
  • If you have downloaded a file online, ensure that you check its extension before clicking on it. Files with multiple extensions can be bad news for your computer.
  • Make it a point to log out once you are done. This is more essential when you are using a system in a cyber café.

  • Ensure that you change your online banking passwords every 6 months, and never share them with anyone.

  • Any kind of financial details should not be shared on phone or email, even if the caller/sender seems genuine or appear to belong from a reputed organization.
