The same could be said for computer security. Sometimes what seems to be an administrative detail is overlooked and becomes a gaping security hole. Good administration must be in place before good security can be achieved. The goal of this course is to teach the students how to operate their computers with security in mind. One important administrative procedure that is often overlooked is the system backup.
Backups are absolutely essential for disaster recovery or cleaning house after a compromise.
Part 3 of Security Essentials teaches the student how to perform this critical task. As a final step, system auditing and log review teaches the student how to maintain an audit capability and the benefits of reviewing those logs regularly.
