The 'Root Console Login' detection rule monitors for logins to the AWS root account through the AWS CloudTrail logs. It aims to identify unauthorized use of the root account, which can lead to potential privilege escalation attacks within an AWS environment. The rule has a high severity level and is enabled by default, requiring a detection period of 15 minutes for deduplication. It references relevant compliance frameworks including CIS benchmarks and MITRE ATT&CK tactics, specifically focusing on valid account access. If a successful root login is detected, the associated attributes include user agent, source IP address, and account IDs, facilitating thorough investigations post-alert. Administrators are advised to act immediately upon detection by reviewing root account activities, revoking unauthorized access, and ensuring immediate change of root credentials if misuse is suspected.
