Core Function of Risk Assessment Process

C.

The core function of the risk assessment process is to identify and assess potential risks to a network or system. This involves analyzing the likelihood and impact of various threats and vulnerabilities, as well as evaluating the effectiveness of existing security controls.

Option A, performing regular network upgrades, is not directly related to risk assessment. While upgrading network infrastructure can improve security posture, it is not a core function of risk assessment.

Option B, performing network optimization, is also not directly related to risk assessment. Network optimization focuses on improving network performance and efficiency, rather than identifying and mitigating security risks.

Option C, performing network posture validation, is closely related to risk assessment. Network posture validation involves assessing the security posture of a network or system to identify potential vulnerabilities and areas for improvement.

Option D, establishing network baselines, is also related to risk assessment. Network baselines provide a reference point for normal network behavior, which can help identify anomalous activity that may indicate a security incident or breach.

Option E, prioritizing network roll-outs, is not directly related to risk assessment. Prioritizing network roll-outs involves identifying which projects should be implemented first based on business needs and resource availability.

In summary, the core function of the risk assessment process is to identify and assess potential risks to a network or system. Options C and D are most closely related to this function, while the other options are less directly related.
