Sigma Rules

View Source
Summary
This detection rule focuses on identifying attempts to export user permission data in Bitbucket. It monitors specific audit log events where the type category is related to 'Users and groups' and captures actions like 'User details export failed', 'User details export started', and 'User details exported'. The rule is set under the requirement that the log level must be at least 'Advance' to ensure that these essential audit events are being logged. Any activity that matches this selection will trigger an alert, aiding organizations in recognizing unauthorized or suspicious attempts to access user permission data, which is crucial for maintaining security and privacy. This detection attains a medium severity rating due to the potential implications of unauthorized data exports in a collaborative environment.
