How to scan a full commit history to detect sensitive secrets

Outdated repositories can pose significant security risks if sensitive information, such as access keys and API tokens, remains exposed within them. GitLab Secret Detection offers a solution by scanning the full commit history of a repository, including all branches, to identify and address such vulnerabilities. By enabling the SECRET_DETECTION_HISTORIC_SCAN variable, users can ensure that no sensitive data is left unchecked, even from old commits or feature branches. The tool not only detects exposed secrets, such as passwords or AWS Access Tokens, but also provides options to address these vulnerabilities by allowing users to view details, create issues in GitLab, or even generate Jira tickets. It offers a multilayered approach to security by scanning for secrets during pushes and in the pipeline, while also automatically revoking certain leaked secrets. Users can customize the detection process with regex patterns to suit their organizational needs, and GitLab encourages trying historical scans to prevent security breaches from forgotten branches or commits.
