IDS/IPS Alert Activity
Intrusion detection and/or prevention systems (IDS/IPS) compare inbound and outbound network traffic against known signatures and/or behaviors of thousands of compromise types (hacker tools, Trojans and other malware). This report collects data on unauthorized wireless access points found on the network and provides a summarized view of the intrusion activity involving an asset in the PCI domain. Use this report to identify attack trends and behavior that could indicate a more significant threat.
Intrusion detection and/or prevention systems can be configured to either alert or stop the intrusion attempt. Without a proactive approach to unauthorized activity detection using these tools, attacks on (or misuse of) PCI resources could go unnoticed in real time. PCI requires that the alerts generated by these tools be monitored so that attempted intrusions can be stopped before they happen.
Relevant data sources
Relevant data sources for this report include IDS/IPS systems, network scan results, or Network Access Control (NAC) logs.
How to configure this report
- Index IDS/IPS alert data in Splunk platform.
- Map the IDS/IPS data to the following Common Information Model fields:
dvc, ids_type, category, signature, severity, src, dest. CIM-compliant add-ons for these data sources perform this step for you.
- Tag the successful synchronization data with "ids" and "attack".
The data in the IDS/IPS report is populated by the Intrusion Detection data model.
Useful searches for troubleshooting
