Chapter 8 (Using Intrusion Detection
Systems) Exam with Answers 2024/2025
Intrusion Detection Systems (IDS) Answer: they are responsible for monitoring activity on a system
or network and then logging or notifying the admin of any suspicious activity
Analysis Methods Answer: - Signature-Based Systems
- Anomaly-Based Systems
- Heuristic
Signature-Based Systems Answer: - determines suspicious activity based on the signatures in a file
that you would need to program or keep up to date
- when the IDS captures behaviors it compares the activity against the signature database and if it
matches it sends out an intrusion notification
- it has few false positives (false alarms)
Anomaly-Based Systems Answer: - determines suspicious activity based on the activity being
abnormal
- it has a baseline for activity, which mean normal activity, and it considers anything outside of that
normal to be suspicious
- also known as behavior-based anomaly
- it has a large number of false positives
Heuristic Answer: - analysis monitors the activity and knows what is suspicious based on past events
- the goal is to detect new viruses that are unknown
- the software usually runs the program in a virtual machine
