The Slack Information Barrier Modified rule is designed to detect changes related to Slack information barriers, which are crucial for ensuring compliance and data governance within teams. This rule triggers alerts when an information barrier is either deleted or updated, as these actions could suggest an attempt to circumvent established data access controls. It analyzes the logs specifically from Slack's Audit Logs to identify these events. The detection is marked for any modifications made by users within the specified Slack workspace, and alerts are generated if an action relevant to information barrier management occurs. The rule records the user email, type of action, and the IP address from which the change was made for further analysis. Monitoring such activities is essential, as they can represent potential defense evasion attempts or policy violations, directly linked to the MITRE ATT&CK technique for Impairing Defenses (TA0005:T1562.001). This makes it a crucial part of any organization's threat detection capabilities within Slack environments.
