I am a student at the University of Advancing Technology in Tempe, AZ. My class is learning more about the Plan-Do-Check-Act Implementation framework. The Harden/Secure step lists several steps that an administrator can take to ensure that a system is strengthened against known attacks, by eliminating vulnerabilities and other weaknesses commonly used by intruders. Of note, I found this step particularly interesting, as it lays the ground work for the system to be able to withstand many of the current attacks. Some of the stated actions to be taken in this step are removing unnecessary services, patch management, eliminating default passwords and installing anti-malware tools. However, I would like to know if there are any recent system hardening procedures that the security community is just starting to adopt?
