What does interval-based IDS refer to?

Interval-based Intrusion Detection Systems (IDS) focus on the analysis of data and events after they occur, rather than detecting or responding to incidents in real-time. This approach involves storing intrusion information and other relevant data for future analysis, allowing for a more comprehensive review of events that have taken place over a set period.

This method is particularly useful for identifying trends, patterns, and potentially missed security incidents that may not have been recognized during real-time monitoring. By preserving data for later investigation, organizations can enhance their understanding of network security incidents and improve their overall security posture.

Other options do not accurately describe interval-based IDS. For example, real-time monitoring corresponds to a more proactive IDS approach, while immediate blocking of suspicious activity relates to intrusion prevention systems. Detection of internal network breaches only indicates a narrow focus that is not characteristic of interval-based IDS, which generally looks at a wider array of data regardless of where the intrusion originated.
