RMiT User Guide – AI Engine Rules

AI Engine rules leverage LogRhythm technology to correlate events across your environment, helping to identify events of interest and potential compliance issues.

Malware Alarm Rule

This alarm rule is the ability to continuously monitor the environment from all layers. This Alarm (#1217) is configured to alert when malicious activity occurs within the environment. This AIE Rule creates an event and notification alarm for malware detection on devices that have been designated as log sources or devices that support network monitoring.

Data Loss Prevention

Data Loss Prevention (DLP) within CCF is focused on protection of sensitive information within the organization’s environment. DLP can be coupled with enabling File Integrity Monitoring (FIM) policies to provide more robust monitoring of sensitive data and user activities impacting that data. For this example, we look at three rules: CCF: Data Loss Prevention, CCF: Corroborated Data Access Anomalies, and Abnormal Amount of Data Transferred. In addition to FIM rules and policies, DLP provides objects that look at suspicious activity that may be indicative of malicious activity impacting sensitive data. Log sources should include systems storing sensitive data (as well as FIM application) to ensure monitoring controls are in place to track tampering of data or unauthorized transfers of data. 

LogRhythm Silent Log Source Error Alarm

Since LogRhythm Enterprise may serve as a mitigating control, it is crucial to be able to alarm on any instance where an in-scope log source does not send any logs. This rule (#1209) could be indicative of a control failure that needs to be addressed. This rule, in conjunction with other auditing failures, allows the organization to limit the time of control failure related to logging and monitoring.

Log Requirements

These AIE rules cover all log sources in your environment, but specifically require logs from anti-malware systems, firewalls, servers, workstations, security enforcing devices, access management systems, and vulnerability detection systems. When configured correctly, LogRhythm’s advanced correlation and AIE rules provide near real-time alerts for malicious activities and/or attacks.
