What are the four IDPS technologies listed?

• A. Network Based, Wireless, Network Behavior Analysis, Host-based
• B. Network Based, Wireless, Cloud-based, Host-based
• C. Network Based, Wireless, Endpoint, Server-based
• D. Network Based, Wireless, Behavioral Analytics, Agent-based

Answer: (A)

IDPS technologies are defined by where and how detection happens. The four standard categories are network-based, wireless, network behavior analysis, and host-based. Network-based systems monitor traffic on a network segment to spot intrusions; wireless focuses on protecting wireless networks and detecting issues like rogue access points; network behavior analysis looks for unusual patterns across the network that may indicate an attack even without specific signatures; and host-based systems run on individual devices to monitor logs, file changes, and host activity for signs of compromise. This combination covers both network-wide visibility and host-level protection, plus behavior-based detection. The other options mix terms like cloud-based, endpoint, server-based, or variants such as behavioral analytics or agent-based, which aren’t the standard four IDPS technologies. Therefore, the listed four—network-based, wireless, network behavior analysis, and host-based—best fit.
