Technical Interview Questions
What are the key differences between IDS and IPS? Can you explain their roles in a security architecture?
How to Answer
- 1
Define IDS as Intrusion Detection System and IPS as Intrusion Prevention System.
- 2
Highlight that IDS monitors and alerts while IPS actively blocks threats.
