    How to prevent future ‘This site may be hacked’ Warning?

    After cleaning your website of the infection and pulling the site back online, now it’s time to harden your website’s security. Follow these steps to keep your website safe.

    1. Update Software

      Firstly, keep your CMS software and extensions up-to-date. Developers regularly release security patches for detected vulnerabilities.

      Secondly, remove unnecessary extensions and plug-ins that are not updated and are not in use. Out of date extensions act as back doors for the hackers.

      Lastly, update the web server too. Also, keep your local PC and network secure. Use up to date OS and antivirus software. (Pro Tip – You can utilize the auto-update feature provided by the software developers to cut the extra work.)

    2. Use Strong Log in Credential

      Brute force attacks accounted for ~16% of hacked sites, according to a survey. A brute force attack is a trial-and-error method to get the correct username & password combinations of the website’s login page. This attack exploits the common mistake of using a weak password.

      Need I say? Use a strong password always. To be more clear, use a combination of letters, digits, and symbols as password instead of your name, website’s name or a proper word. Another security best practice is to limit the number of login attempts and adding a two-step authentication method.

    3. Switch to HTTPS

      HTTPS stands for Hyper Text Transfer Protocol Secure. It allows secure exchange of files on the World Wide Web for it enables encrypted communication between a remote user and the primary web server.
