Group, subgroup, or project owners can use scan execution policies to require that security scans run on a specified
schedule or with the project (or multiple projects if the policy is defined at a group or subgroup level) pipeline. Required scans are injected into the CI pipeline as new jobs
When you save a new policy, GitLab validates its contents against [this JSON schema](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/validators/json_schemas/security_orchestration_policy.json).
If you're not familiar with how to read [JSON schemas](https://json-schema.org/),
the following sections and tables provide an alternative.
| Field | Type | Possible values | Description |
|-------|------|-----------------|-------------|
| `scan_execution_policy` | `array` of scan execution policy | | List of scan execution policies (maximum 5) |
| `agents` | `object` | | The name of the [GitLab agents](../../clusters/agent/index.md) where [cluster image scanning](../../clusters/agent/vulnerabilities.md) will run. The object key is the name of the Kubernetes cluster configured for your project in GitLab. You can use the optional value of the object to select and scan specific Kubernetes resources. |
Other elements of the CRON syntax may work in the cadence field, however, GitLab does not officially test or support them. The CRON expression is evaluated in UTC by default. If you have a self-managed GitLab instance and have [changed the server timezone](../../../administration/timezone.md), the CRON expression is evaluated with the new timezone.
### `agent` schema
Use this schema to define `agents` objects in the [`schedule` rule type](#schedule-rule-type).
| `site_profile` | `string` | Name of the selected [DAST site profile](../dast/index.md#site-profile). | The DAST site profile to execute the DAST scan. This field should only be set if `scan` type is `dast`. |
| `scanner_profile` | `string` or `null` | Name of the selected [DAST scanner profile](../dast/index.md#scanner-profile). | The DAST scanner profile to execute the DAST scan. This field should only be set if `scan` type is `dast`.|
| `variables` | `object` | | A set of CI variables, supplied as an array of `key: value` pairs, to apply and enforce for the selected scan. The `key` is the variable name, with its `value` provided as a string. This parameter supports any variable that the GitLab CI job supports for the specified scan. |
Note the following:
- You must create the [site profile](../dast/index.md#site-profile) and [scanner profile](../dast/index.md#scanner-profile)
with selected names for each project that is assigned to the selected Security Policy Project.
Otherwise, the policy is not applied and a job with an error message is created instead.
- Once you associate the site profile and scanner profile by name in the policy, it is not possible
to modify or delete them. If you want to modify them, you must first disable the policy by setting
the `active` flag to `false`.
- When configuring policies with a scheduled DAST scan, the author of the commit in the security
policy project's repository must have access to the scanner and site profiles. Otherwise, the scan
is not scheduled successfully.
- For a secret detection scan, only rules with the default ruleset are supported. [Custom rulesets](../secret_detection/index.md#custom-rulesets)
are not supported.
- A secret detection scan runs in `normal` mode when executed as part of a pipeline, and in
- A container scanning scan that is configured for the `pipeline` rule type ignores the agent defined in the `agents` object. The `agents` object is only considered for `schedule` rule types.
An agent with a name provided in the `agents` object must be created and configured for the project.
