Building Practical Mitigations

Knowing attacks is only half the job; applying mitigations is the rest. A mitigation is any measure that reduces the likelihood or impact of a threat. No control stops everything, so you layer many to cut overall risk.

This lesson gathers the practical, everyday defenses a technician applies to harden a network against the attacks you have studied.

Patch management is one of the most effective defenses. Most attacks exploit known vulnerabilities that already have fixes. Applying security updates promptly to operating systems, applications, and network gear closes those holes.

Automated patching and a regular update schedule keep systems current, dramatically shrinking the window in which attackers can use a known exploit against you.
