1 Always install a good antivirus software and keep it up-to-date. Also install a good anti-spyware to keep spyware away from your computer.
2 Always visit known and trusted websites. If you are about to visit an unknown website, ensure that you do not click on those untrusted links and banners.
3 Perform a virus scan on the files/email attachments that you download before executing them.
4 Regularly update your operating system and browser software. For a better security, it is recommended that you surf the Internet through the latest version of your browser program.
5 Never share your password (email, bank logins etc.) with any one for any reason. Choose a strong password (A blend of alphanumeric+special symbols) and change it regularly, eg. every 3 months. Avoid using easy-to-guess passwords. (ex. pet’s name or kid’s name)
6 Always type the URL of the website in your browser’s address bar to enter the login pages.
7 Before you enter your password on any login page, ensure that you see https instead of http in your browser’s address bar. Example.https://mail.google.com/ instead of http://mail.google.com/. HTTPS protocol implements SSL (Secure Sockets Layer) and provide better security than a normal HTTP. For more information on HTTPS and SSL see Know More About Secure Sockets Layer (SSL).
8 Beware of phishing emails! Do not respond to any email that request you to update your login details by clicking on a link in the body of the email. Such links can lead to Fake Login Pages (Spoofed Pages). For more information on phishing refer How to Identify and Avoid Phishing Scam. Also refer my other post on How to Protect an Email Account.
9 Always hit the logout button to close your login session rather than abruptly terminating the browser window. Also, clear your web browser caches after every session to remove the temporary files stored in the memory and hard disk of your PC.
10 Avoid (Stop) using any public computers or computers in the Internet cafes to access any sensitive/confidential information. Also, avoid such computers to log in to your email/bank accounts. On a public computer, there is every chance of spyware and malware infections to be present.
By following the above 10 tips, your Internet security can be guaranteed up to 90 percent. I hope this information will help my readers for keeping themselves safe from any of the online insecurities.
