Answers
C.
Installing and updating antivirus
D.
Installing all available patches
Answers
D.
Installing all available patches
Suggested answer: A

Explanation:

The first step in reducing the attack surface of vulnerable, end-of-support systems is to apply hardening recommendations. Hardening involves applying security configurations, such as disabling unnecessary services, enforcing strong authentication, and tightening access controls to mitigate vulnerabilities on systems that can no longer receive patches or support. While patching and deploying security tools like IPS/IDS and antivirus are important, hardening addresses the fundamental weakness of these legacy systems by reducing their exposure to threats. CASP+ recommends hardening as a crucial measure in environments where patching or upgrading may not be feasible, particularly for unsupported systems.
