Final answer:
The system admin is reviewing the practice of C. patching, which is essential for fixing vulnerabilities and preventing their exploitation by cyber attackers.
Step-by-step explanation:
The remediation practice the system admin is reviewing is likely C. Patching. Patching is a critical security measure that involves updating software and systems to fix vulnerabilities that could be exploited by cyber attackers. A robust patch management process is crucial because it helps to protect against the exploitation of known vulnerabilities in software and operating systems. Without timely patching, organizations leave themselves open to cyber attacks such as ransomware, malware infections, and unauthorized data access.
Organizations should have a patch management policy that includes procedures for regularly checking for updates from software vendors, assessing the relevance and urgency of patches for their environment, and applying the patches in a timely manner. It's also important to verify that patches are successfully applied and to test systems after patching to ensure that there are no adverse effects on system performance or functionality. The system admin understands that reinforcing patching practices is vital for maintaining the security and integrity of the company's IT infrastructure.
