Exam CAS-004 topic 1 question 413 discussion

Option C provides a comprehensive approach to directly addressing the vulnerabilities highlighted in the security controls assessment. Updating antivirus definitions ensures protection against known threats, NGFW with logging enhances detection of active attacks, USB port lockers physically secure critical servers, and weekly SCAP scans help maintain proper configuration and compliance.

The best answer is C. Update antivirus definitions, install NGFW with logging enabled, use USB port lockers, and run SCAP scans weekly. This set of actions directly addresses the identified vulnerabilities: updating antivirus definitions resolves out-of-date definitions, installing a Next-Generation Firewall (NGFW) with logging can detect active attacks and address misconfigured operating systems, using USB port lockers mitigates the risk of unimpeded access to critical servers’ USB ports, and running SCAP scans weekly ensures ongoing vulnerability management and detection of misconfigurations.

To reduce the risks identified in the security controls assessment for the CASP+ certification, the most appropriate action would be: C. Update antivirus definitions, install NGFW with logging enabled, use USB port lockers, and run SCAP scans weekly. This option addresses the specific vulnerabilities identified in the assessment: Updating antivirus definitions helps with the out-of-date definitions vulnerability. Installing a Next-Generation Firewall (NGFW) with logging enabled helps address misconfigured operating systems and an inability to detect active attacks. Using USB port lockers helps prevent unimpeded access to critical servers' USB ports. Running Security Content Automation Protocol (SCAP) scans weekly aids in identifying and addressing security issues proactively. Overall, this combination of measures aligns well with the identified vulnerabilities and would likely be the most effective in reducing the risks for the organization.
