The availability, integrity, and confidentiality of hosts and their data. They can help you detect, alert on, and protect against network traffic that could threaten Together, network analysis and intrusion policies provideīroad and deep packet inspection. Prevention (additional preprocessing and intrusion rules) phase. System analyzes traffic, the network analysis (decoding and preprocessing) phase occurs before and separately from the intrusion Intrusion policies are paired with variable sets, which allow you to use named values to accurately reflect your network environment.īoth network analysis and intrusion policies are invoked by a parent access control policy, but at different times. In an intrusion prevention deployment, when the system examines packets:Ī network analysis policy governs how traffic is decoded and preprocessed so it can be further evaluated, especially for anomalous traffic that might signal an intrusion attempt.Īn intrusion policy uses intrusion and preprocessor rules (sometimes referred to collectively as intrusion rules) to examine the decoded packets for attacks based on patterns. The term intrusion prevention includes the concept of intrusion detection, but adds the ability to block or alter malicious traffic as it travels across
The term intrusion detection generally refers to the process of passively monitoring and analyzing network traffic for potential intrusions and storingĪttack data for security analysis. Network analysis and intrusion policies work together as part of the intrusion detection and prevention feature.
