How are security patches typically prioritized?

Security patches are prioritized primarily based on the severity and exploitability of vulnerabilities. This approach ensures that the most critical vulnerabilities—those that could be exploited by attackers to gain unauthorized access or cause significant damage—are addressed first.

Evaluating severity involves understanding how serious a vulnerability is—whether it allows for remote code execution, data breaches, or other significant threats. The exploitability assessment considers how easily an attacker can take advantage of the vulnerability. If a vulnerability is both severe and easily exploitable, it will typically rise to the top of the patching priority list. This method helps organizations allocate resources effectively and mitigate risks in a timely manner.

Other factors, while they may be relevant in specific contexts, do not generally drive the prioritization of security patches. For example, performance impacts, the number of users affected, and the age of the software version can be considerations, but they do not take precedence over the critical nature of vulnerabilities in ensuring system security.
