Combined security systems that both detect malicious activity and automatically block threats.
Intrusion Detection and Prevention Systems (IDPS) combine the monitoring capabilities of IDS with the active blocking capabilities of IPS. Modern security platforms typically offer both functions, allowing organisations to monitor some traffic while actively blocking clearly malicious activity. IDPS can operate in detection mode (alert only) while being tuned, then switch to prevention mode once false positives are minimised. This approach provides flexibility while managing the risk of blocking legitimate traffic.
Why It Matters
The DSC Perspective:
IDPS gives you both visibility and protection. Most modern firewalls and security platforms provide IDPS functionality—understanding this helps you configure them effectively and answer compliance questions about network security controls.
