What is patch management and why is it critical?

• A. The process of applying updates to software and firmware; reduces exploitable vulnerabilities and ensures compliance.
• B. The process of creating new software features from scratch.
• C. The practice of assigning IP addresses to devices on a network.
• D. The process of backing up data to offsite storage.

Answer: (A)

Patch management is the ongoing process of identifying, testing, and applying updates to software and firmware to fix vulnerabilities, improve stability, and meet security requirements. It is critical because unpatched systems are prime targets for attackers who can exploit known flaws to gain access, install malware, or steal data. Keeping patches up to date reduces the attack surface, closes security gaps, and helps ensure compliance with security policies and regulatory requirements. A solid patch management approach also involves keeping an up-to-date inventory of assets, prioritizing patches based on risk (with critical vulnerabilities addressed first), testing updates in a controlled environment before deployment, deploying in stages, and having a rollback plan if an update causes issues, plus continuous verification that patches are applied and effective. The other options describe activities such as creating new software features, assigning IP addresses, or backing up data, which are not about keeping software up to date.
