What is the main purpose of vulnerability management?

Correct answer: Identify, assess, prioritize, and remediate security vulnerabilities

Option A is correct because vulnerability management is a continuous lifecycle process encompassing identification of weaknesses through scanning and assessment, severity prioritization using frameworks such as CVSS, and systematic remediation or acceptance of risk to reduce the organization's attack surface. Option B is incorrect because no security program can prevent all attacks; the goal of vulnerability management is risk reduction, not absolute prevention. Option C is wrong because eliminating all software is neither practical nor the objective; the aim is to manage flaws within necessary software, not to remove it. Option D is incorrect because blocking all network traffic is a network control that would render systems unusable and has no relationship to the broader vulnerability identification and remediation lifecycle.
