* [Rule Tuningw] Add Console Session Filtering to AWS Temporary Credential Detection Rules Added `aws.cloudtrail.session_credential_from_console` field filtering to 2 rules to reduce false positives from legitimate console login sessions. Console logins automatically issue temporary "ASIA" credentials, which previously triggered alerts for rules monitoring session token abuse. - Updated false positives sections to reflect automatic console session filtering - Updated investigation guides to note that alerts indicate non-console temporary credential usage - min_stack_version = "9.2.0" because this field was introduced in AWS Integration version 4.6.0. 9.2.0 is the earliest major stack version supported. Impact - Significantly reduces false positives from legitimate AWS Management Console usage - Improves rule fidelity by focusing detection on programmatic abuse of temporary credentials (CLI, SDK, stolen credentials) * update boolean field value for aws.cloudtrail.session_credential_from_console update boolean field value for aws.cloudtrail.session_credential_from_console * removing filebeat compatibility removing filebeat compatibility
rules/
Rules within this folder are organized by solution or platform. The structure is flattened out, because nested file hierarchies are hard to navigate and find what you're looking for. Each directory contains several .toml files, and the primary ATT&CK tactic is included in the file name when it's relevant (i.e. windows/execution_via_compiled_html_file.toml)
