Summary
In this chapter, you learned how to protect your Moodle system from misuse and protect users' privacy. However, it is important to stress that Moodle's security is only a single variable in the overall equation. Make sure that all other underlying software, infrastructure, and hardware components are set up correctly as well.
Most Moodle systems run on the LAMP platform, which has proven to be very secure if configured correctly. Moodle's developers are very conscious that security is vital when dealing with personal user data such as grades. Hence, the topic has been given the highest priority. However, there is no guarantee that your system is 100% protected against misuse. New hacking techniques will emerge and users will continue to be careless with their credentials (you have all seen the post-it notes under the keyboard). So, make sure the security patches and updates on your entire system, not just Moodle, are always up to date and keep educating your users...
