CompTIA Cloud+ (CV0-002) — Question 130

A cloud administrator is securing an application hosted by an IaaS provider. The operating system on the VM has been updated. Which of the following should the administrator use to BEST secure the VM from attacks against vulnerable services regardless of operating system?

Answer options

• A. Firewall
• B. Antivirus
• C. Intrusion detection
• D. Patch management

Correct answer: C

Explanation

Using Intrusion detection is the best approach as it monitors network traffic for suspicious activities and potential attacks against vulnerable services, regardless of the OS. While a Firewall can block unauthorized access and Antivirus can protect against malware, they do not specifically address vulnerabilities in services. Patch management is crucial but focuses on keeping software up to date rather than monitoring for ongoing threats.
