Question #: 369
Topic #: 1
[All CCSP Questions]

A variety of security systems can be integrated within a network--some that just monitor for threats and issue alerts, and others that take action based on signatures, behavior, and other types of rules to actively stop potential threats.
Which of the following types of technologies is best described here?

  • A. IDS
  • B. IPS
  • C. Proxy
  • D. Firewall
Show Suggested Answer Hide Answer
Suggested Answer: B 🗳️
An intrusion prevention system (IPS) can inspect traffic and detect any suspicious traffic based on a variety of factors, but it can also actively block such traffic.
Although an IDS can detect the same types of suspicious traffic as an IPS, it is only design to alert, not to block. A firewall is only concerned with IP addresses, ports, and protocols; it cannot be used for the signature-based detection of traffic. A proxy can limit or direct traffic based on more extensive factors than a network firewall can, but it's not capable of using the same signature detection rules as an IPS.

IDS has a only detection capabilities while IPS can response to detected events. As it's also required response then answer is IPS.

Both IDS and IPS were described in the question. Had to assume the latter was what the question was referring to.
