| [Container Scanning](../container_scanning/index.md) | Uses `clair`. The latest `clair-db` version is used for each job by running the [`latest` Docker image tag](https://gitlab.com/gitlab-org/gitlab/blob/438a0a56dc0882f22bdd82e700554525f552d91b/lib/gitlab/ci/templates/Security/Container-Scanning.gitlab-ci.yml#L37). The`clair-db` database [is updated daily according to the author](https://github.com/arminc/clair-local-scan#clair-server-or-local). |
| [Container Scanning](../container_scanning/index.md) | Uses either `trivy` or `clair`. For the `trivy` scanner, a job runs on a daily basis to build a new image with the latest vulnerability database updates from the [upstream `trivy-db`](https://github.com/aquasecurity/trivy-db). For the `clair` scanner, the latest `clair-db` version is used;`clair-db` database [is updated daily according to the author](https://github.com/arminc/clair-local-scan#clair-server-or-local). |
| [Dependency Scanning](../dependency_scanning/index.md) | Relies on `bundler-audit` (for Ruby gems), `retire.js` (for npm packages), and `gemnasium` (the GitLab tool for all libraries). Both `bundler-audit` and `retire.js` fetch their vulnerabilities data from GitHub repositories, so vulnerabilities added to `ruby-advisory-db` and `retire.js` are immediately available. The tools themselves are updated once per month if there's a new version. The [Gemnasium DB](https://gitlab.com/gitlab-org/security-products/gemnasium-db) is updated at least once a week. See our [current measurement of time from CVE being issued to our product being updated](https://about.gitlab.com/handbook/engineering/development/performance-indicators/#cve-issue-to-update). |
| [Dynamic Application Security Testing (DAST)](../dast/index.md) | The scanning engine is updated on a periodic basis. See the [version of the underlying tool `zaproxy`](https://gitlab.com/gitlab-org/security-products/dast/blob/master/Dockerfile#L1). The scanning rules are downloaded at scan runtime. |
| [Static Application Security Testing (SAST)](../sast/index.md) | Relies exclusively on [the tools GitLab wraps](../sast/index.md#supported-languages-and-frameworks). The underlying analyzers are updated at least once per month if a relevant update is available. The vulnerabilities database is updated by the upstream tools. |
