Identify the types of IDPSs

Explanation:

Intrusion Detection and Prevention Systems $($IDPSs$)$ come in various forms, including network$-$based $($NIDPS$),$ host$-$based $($HIDPS$),$ wireless $($WIDPS$),$ and network behavior analysis $($NBA$).$ Each type has its own method of detecting and potentially preventing intrusions on a network or system.

Step $2$

Understand the functionalities of each IDPS

Explanation:

NIDPS monitors network traffic for suspicious activity, HIDPS checks individual host or device, WIDPS focuses on wireless networks, and NBA evaluates network traffic to identify threats that generate unusual traffic patterns.

Step $3$

Consider the complexity factors

Explanation:

When determining complexity, consider factors such as the size of the environment, the diversity of the network and systems, the level of expertise required to configure and maintain the IDPS, and the integration with existing security measures.

Step $4$

Evaluate and compare implementation complexities

Explanation:

Students must weigh the pros and cons of each IDPS type based on the complexity factors. For example, a NIDPS might be complex due to the need to analyze vast amounts of network traffic, while a HIDPS might be complex due to the need for deployment on multiple hosts.

Answer

The most complex IDPS to implement will vary based on the specific environment and requirements. Students should provide reasoned arguments for their choice, considering the complexity factors for each IDPS type.
