Acronym for Intrusion Detection System—monitoring for malicious network or system activity.
IDS stands for Intrusion Detection System. See 'Intrusion Detection System' for the full definition. IDS capabilities are now commonly integrated into firewalls, EDR solutions, and SIEM platforms rather than deployed as standalone systems.
Why It Matters
The DSC Perspective:
Compliance questionnaires often ask about intrusion detection. Understanding IDS helps you identify which of your existing tools provide this capability—your firewall, EDR, or SIEM likely includes IDS functionality.
