Scan result policies (ULTIMATE)

You can use scan result policies to take action based on scan results. For example, one type of scan result policy is a security approval policy that allows approval to be required based on the findings of one or more security scan jobs. Scan result policies are evaluated after a CI scanning job is fully executed. The following video gives you an overview of GitLab scan result policies:

See the video: Overview of GitLab Scan Result Policies.

Scan result policy editor

Introduced in GitLab 14.8.

NOTE: Only project Owners have the permissions to select Security Policy Project.

Once your policy is complete, save it by selecting Create merge request at the bottom of the editor. This redirects you to the merge request on the project's configured security policy project. If a security policy project doesn't link to your project, GitLab creates such a project for you. Existing policies can also be removed from the editor interface by selecting Delete policy at the bottom of the editor.

Most policy changes take effect as soon as the merge request is merged. Any changes that do not go through a merge request and are committed directly to the default branch may require up to 10 minutes before the policy changes take effect.

The policy editor supports YAML mode and rule mode.

Scan result policies schema

The YAML file with scan result policies consists of an array of objects matching the scan result policy schema nested under the scan_result_policy key. You can configure a maximum of five policies under the scan_result_policy key.

When you save a new policy, GitLab validates its contents against this JSON schema. If you're not familiar with how to read JSON schemas, the following sections and tables provide an alternative.

Field	Type	Possible values	Description
scan_result_policy	array of Scan Result Policy		List of scan result policies (maximum 5).

Scan result policy schema

Field	Type	Possible values	Description
name	string		Name of the policy. Maximum of 255 characters.
description (optional)	string		Description of the policy.
enabled	boolean	true, false	Flag to enable (true) or disable (false) the policy.
rules	array of rules		List of rules that the policy applies.
actions	array of actions		List of actions that the policy enforces.

scan_finding rule type

This rule enforces the defined actions based on the information provided.

Field	Type	Possible values	Description
type	string	scan_finding	The rule's type.
branches	array of string	[] or the branch's name	Applicable only to protected target branches. An empty array, [], applies the rule to all protected target branches.
scanners	array of string	sast, secret_detection, dependency_scanning, container_scanning, dast, coverage_fuzzing, api_fuzzing	The security scanners for this rule to consider.
vulnerabilities_allowed	integer	Greater than or equal to zero	Number of vulnerabilities allowed before this rule is considered.
severity_levels	array of string	info, unknown, low, medium, high, critical	The severity levels for this rule to consider.
vulnerability_states	array of string	newly_detected, detected, confirmed, resolved, dismissed	The vulnerability states for this rule to consider when the target branch is set to the default branch. The newly_detected state considers all newly detected vulnerabilities regardless of their status or dismissal. The other states consider findings that match the selected state and already exist in the default branch.

require_approval action type

This action sets an approval rule to be required when conditions are met for at least one rule in the defined policy.

Field	Type	Possible values	Description
type	string	require_approval	The action's type.
approvals_required	integer	Greater than or equal to zero	The number of MR approvals required.
user_approvers	array of string	Username of one of more users	The users to consider as approvers. Users must have access to the project to be eligible to approve.
user_approvers_ids	array of integer	ID of one of more users	The IDs of users to consider as approvers. Users must have access to the project to be eligible to approve.
group_approvers	array of string	Path of one of more groups	The groups to consider as approvers. Users with direct membership in the group are eligible to approve.
group_approvers_ids	array of integer	ID of one of more groups	The IDs of groups to consider as approvers. Users with direct membership in the group are eligible to approve.

Requirements and limitations:

• You must add the respective security scanning tools. Otherwise, scan result policies won't have any effect.
• The maximum number of policies is five.
• Each policy can have a maximum of five rules.

Example security scan result policies project

You can use this example in a .gitlab/security-policies/policy.yml file stored in a security policy project:

---
scan_result_policy:
- name: critical vulnerability CS approvals
  description: critical severity level only for container scanning
  enabled: true
  rules:
  - type: scan_finding
    branches:
    - main
    scanners:
    - container_scanning
    vulnerabilities_allowed: 0
    severity_levels:
    - critical
    vulnerability_states:
    - newly_detected
  actions:
  - type: require_approval
    approvals_required: 1
    user_approvers:
    - adalberto.dare
- name: secondary CS approvals
  description: secondary only for container scanning
  enabled: true
  rules:
  - type: scan_finding
    branches:
    - main
    scanners:
    - container_scanning
    vulnerabilities_allowed: 1
    severity_levels:
    - low
    - unknown
    vulnerability_states:
    - newly_detected
  actions:
  - type: require_approval
    approvals_required: 1
    user_approvers:
    - sam.white

In this example:

• Every MR that contains new critical vulnerabilities identified by container scanning requires one approval from alberto.dare.
• Every MR that contains more than one new low or unknown vulnerability identified by container scanning requires one approval from sam.white.

Example for Scan Result Policy editor

You can use this example in the YAML mode of the Scan Result Policy editor. It corresponds to a single object from the previous example:

- name: critical vulnerability CS approvals
  description: critical severity level only for container scanning
  enabled: true
  rules:
  - type: scan_finding
    branches:
    - main
    scanners:
    - container_scanning
    vulnerabilities_allowed: 1
    severity_levels:
    - critical
    vulnerability_states:
    - newly_detected
  actions:
  - type: require_approval
    approvals_required: 1
    user_approvers:
    - adalberto.dare
