תקציר	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).	Vulnerability assessment is a systematic process of identifying, quantifying, and prioritizing security weaknesses in systems, networks, and applications. Using automated scanning tools and manual techniques, organizations discover unpatched software, misconfigurations, weak cryptographic practices, and other exposures that attackers could exploit.
