CompTIA Security Plus Mock Test Q628

In order to maintain oversight of a third party service provider, the company is going to implement a Governance, Risk, and Compliance (GRC) system. This system is promising to provide overall security posture coverage. Which of the following is the MOST important activity that should be considered?

A. Continuous security monitoring
B. Baseline configuration and host hardening
C. Service Level Agreement (SLA) monitoring
D. Security alerting and trending


Correct Answer: A
Section: Threats and Vulnerabilities

Explanation:
The company is investing in a Governance, Risk, and Compliance (GRC) system to provide overall security posture coverage. This is great for testing the security posture. However, to be effective and ensure the company always has a good security posture, you need to monitor the security continuously.
Once a baseline security configuration is documented, it is critical to monitor it to see that this baseline is maintained or exceeded. A popular phrase among personal trainers is “that which gets measured gets improved.” Well, in network security, “that which gets monitored gets secure.”
Continuous monitoring means exactly that: ongoing monitoring. This may involve regular measurements of network traffic levels, routine evaluations for regulatory compliance, and checks of network security device configurations.

Incorrect Answers:
B: Baseline configuration and host hardening should be performed initially or when new computer systems are implemented. However, after that has been done, you should continue to monitor the security of the system.
C: Service Level Agreement (SLA) monitoring is performed to ensure that the availability of the system meets SLA’s agreed with your customers. It does not affect or ensure the security of the system.
D: Security alerting and trending is important. However, this can only happen with continuous security monitoring.
