सारांश	An Intrusion Detection System (IDS) is a security tool that monitors network traffic and system activity to identify unauthorized access attempts, malware infections, and policy violations. Introduced by Dorothy Denning in 1987, IDS employs two main detection paradigms: signature-based (matching known attack patterns) and anomaly-based (identifying deviations from normal behavior).	Penetration testing is an authorized, controlled simulated attack on systems, networks, and applications to evaluate their security defenses. Unlike vulnerability assessment (which identifies weaknesses), penetration testing actively exploits vulnerabilities to demonstrate real-world impact, confirm exploitability, and assess an organization's incident response capabilities.
