Certified Cloud Security Professional (CCSP) — Question 160

Although host-based and network-based IDSs perform similar functions and have similar capabilities, which of the following is an advantage of a network-based
IDS over a host-based IDS, assuming all capabilities are equal?

Answer options

• A. Segregated from host systems
• B. Network access
• C. Scalability
• D. External to system patching

Correct answer: C

Explanation

The correct answer is C, as network-based IDSs can easily scale to monitor larger networks without being limited by individual host resources. Options A and D are not advantages since they relate to isolation and patching, while B, although a feature, does not imply the scalability that network-based systems offer.
