Question

A large organization is redesigning its network infrastructure to increase security and reduce the potential attack surface. the organization considers implementing an intrusion prevention system (ips) and an intrusion detection system (ids) into its security zones. the it manager wants to secure connectivity and considers different network appliances and port security measures. which of the following options best describes the benefits and disadvantages of placing the ips/ids devices inline with the network traffic?

A) Improved security, Increased potential attack surface
B) Reduced potential attack surface, Limited monitoring capability
C) Enhanced connectivity, Increased latency
D) Improved monitoring capability, Decreased security

Answer 1

IPS/IDS devices inline with network traffic provide real-time threat prevention and improved monitoring but may introduce increased latency affecting network performance.

Step-by-step explanation:

Placing IPS/IDS devices inline with the network traffic certainly has benefits, but there are trade-offs as well. The most significant advantage is the improved monitoring capability; they actively analyze the traffic and can take immediate action on detected threats, hence providing real-time protection.

By being in-line, these systems can prevent attacks by blocking malicious traffic before it reaches its target. However, a primary disadvantage is the potential increase in latency, as the IPS/IDS needs to process the traffic, which can slightly delay data transmission, and could affect network performance, particularly if the device is underpowered or improperly configured.
