How should admins deal with vulnerabilities that they find in their systems?

When vulnerabilities are identified in systems, it is crucial for administrators to act immediately to mitigate the risk of exploitation by attackers. The appropriate response involves applying fixes, such as software patches or configuration changes, to close the vulnerability. This proactive approach is necessary to protect the integrity, confidentiality, and availability of the system resources and data. It's important to prioritize these actions based on the severity and exploitability of the vulnerability to ensure that the most critical issues are addressed first.
