# Static Application Security Testing (SAST)
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/3775) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 10.3.
|
|
|
|
NOTE: **Note:**
|
|
The whitepaper ["A Seismic Shift in Application Security"](https://about.gitlab.com/resources/whitepaper-seismic-shift-application-security/)
|
|
explains how 4 of the top 6 attacks were application based. Download it to learn how to protect your
|
|
organization.
|
|
|
|
If you're using [GitLab CI/CD](../../../ci/README.md), you can analyze your source code for known
|
|
vulnerabilities using Static Application Security Testing (SAST). GitLab checks the SAST report and
|
|
compares the found vulnerabilities between the source and target branches.
|
|
|
|
Details of the vulnerabilities found are included in the merge request. **(ULTIMATE)**
|
|
|
|
|
|
|
|
The results are sorted by the priority of the vulnerability:
|
|
|
|
1. Critical
|
|
1. High
|
|
1. Medium
|
|
1. Low
|
|
1. Unknown
|
|
1. Everything else
|
|
|
|
A pipeline consists of multiple jobs, including SAST and DAST scanning. If any job fails to finish
|
|
for any reason, the security dashboard does not show SAST scanner output. For example, if the SAST
|
|
job finishes but the DAST job fails, the security dashboard does not show SAST results. On failure,
|
|
the analyzer outputs an [exit code](../../../development/integrations/secure.md#exit-code).
|
|
|
|
## Use cases
|
|
|
|
- Your code has a potentially dangerous attribute in a class, or unsafe code
|
|
that can lead to unintended code execution.
|
|
- Your application is vulnerable to cross-site scripting (XSS) attacks that can
|
|
be leveraged to unauthorized access to session data.
|
|
|
|
## Requirements
|
|
|
|
To run SAST jobs, by default, you need GitLab Runner with the
|
|
[`docker`](https://docs.gitlab.com/runner/executors/docker.html) or
|
|
[`kubernetes`](https://docs.gitlab.com/runner/install/kubernetes.html) executor.
|
|
If you're using the shared runners on GitLab.com, this is enabled by default.
|
|
|
|
CAUTION: **Caution:**
|
|
Our SAST jobs require a Linux container type. Windows containers are not yet supported.
|
|
|
|
CAUTION: **Caution:**
|
|
If you use your own runners, make sure the Docker version installed
|
|
is **not** `19.03.0`. See [troubleshooting information](#error-response-from-daemon-error-processing-tar-file-docker-tar-relocation-error) for details.
|
|
|
|
## Supported languages and frameworks
|
|
|
|
GitLab SAST supports a variety of languages, package managers, and frameworks. Our SAST security scanners also feature automatic language detection which works even for mixed-language projects. If any supported language is detected in project source code we will automatically run the appropriate SAST analyzers.
|
|
|
|
You can also [view our language roadmap](https://about.gitlab.com/direction/secure/static-analysis/sast/#language-support) and [request other language support by opening an issue](https://gitlab.com/groups/gitlab-org/-/epics/297).

## Contribute your scanner
|
|
|
|
The [Security Scanner Integration](../../../development/integrations/secure.md) documentation explains how to integrate other security scanners into GitLab.
|
|
|
|
## Configuration
|
|
|
|
To configure SAST for a project you can:
|
|
|
|
- Use [Auto SAST](../../../topics/autodevops/stages.md#auto-sast) provided by
|
|
[Auto DevOps](../../../topics/autodevops/index.md).
|
|
- [Configure SAST manually](#configure-sast-manually).
|
|
- [Configure SAST using the UI](#configure-sast-in-the-ui) (introduced in GitLab 13.3).
|
|
|
|
### Configure SAST manually
|
|
|
|
For GitLab 11.9 and later, to enable SAST you must [include](../../../ci/yaml/README.md#includetemplate)
|
|
the [`SAST.gitlab-ci.yml` template](https://gitlab.com/gitlab-org/gitlab/blob/master/lib/gitlab/ci/templates/Security/SAST.gitlab-ci.yml)
|
|
provided as a part of your GitLab installation. For GitLab versions earlier than 11.9, you
|
|
can copy and use the job as defined that template.
|
|
|
|
Add the following to your `.gitlab-ci.yml` file:
|
|
|
|
```yaml
|
|
include:
|
|
- template: Security/SAST.gitlab-ci.yml
|
|
```
|
|
|
|
The included template creates SAST jobs in your CI/CD pipeline and scans
|
|
your project's source code for possible vulnerabilities.
|
|
|
|
The results are saved as a
|
|
[SAST report artifact](../../../ci/pipelines/job_artifacts.md#artifactsreportssast)
|
|
that you can later download and analyze. Due to implementation limitations, we
|
|
always take the latest SAST artifact available.
|
|
|
|
### Configure SAST in the UI **(ULTIMATE)**
|
|
|
|
> - [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/3659) in GitLab Ultimate 13.3.
|
|
> - [Improved](https://gitlab.com/gitlab-org/gitlab/-/issues/232862) in GitLab Ultimate 13.4.
|
|
> - [Improved](https://gitlab.com/groups/gitlab-org/-/epics/3635) in GitLab Ultimate 13.5.
|
|
|
|
You can enable and configure SAST with a basic configuration using the **SAST Configuration**
|
|
page:
|
|
|
|
1. From the project's home page, go to **Security & Compliance** > **Configuration** in the
|
|
left sidebar.
|
|
1. If the project does not have a `.gitlab-ci.yml` file, click **Enable** in the Static Application Security Testing (SAST) row, otherwise click **Configure**.
|
|
1. Enter the custom SAST values.
|
|
|
|
Custom values are stored in the `.gitlab-ci.yml` file. For variables not in the SAST Configuration page, their values are left unchanged. Default values are inherited from the GitLab SAST template.
|
|
1. Optionally, expand the **SAST analyzers** section, select individual [SAST analyzers](analyzers.md) and enter custom analyzer values.
|
|
1. Click **Create Merge Request**.
|
|
1. Review and merge the merge request.
|
|
|
|
### Customizing the SAST settings
|
|
|
|
The SAST settings can be changed through [environment variables](#available-variables)
|
|
by using the
|
|
[`variables`](../../../ci/yaml/README.md#variables) parameter in `.gitlab-ci.yml`.
|
|
In the following example, we include the SAST template and at the same time we
|
|
set the `SAST_GOSEC_LEVEL` variable to `2`:
|
|
|
|
```yaml
|
|
include:
|
|
- template: Security/SAST.gitlab-ci.yml
|
|
|
|
variables:
|
|
SAST_GOSEC_LEVEL: 2
|
|
```
|
|
|
|
Because the template is [evaluated before](../../../ci/yaml/README.md#include)
|
|
the pipeline configuration, the last mention of the variable takes precedence.
|
|
|
|
### Overriding SAST jobs
|
|
|
|
CAUTION: **Deprecation:**
|
|
Beginning in GitLab 13.0, the use of [`only` and `except`](../../../ci/yaml/README.md#onlyexcept-basic)
|
|
is no longer supported. When overriding the template, you must use [`rules`](../../../ci/yaml/README.md#rules) instead.
|
|
|
|
To override a job definition, (for example, change properties like `variables` or `dependencies`),
|
|
declare a job with the same name as the SAST job to override. Place this new job after the template
|
|
inclusion and specify any additional keys under it. For example, this enables `FAIL_NEVER` for the
|
|
`spotbugs` analyzer:
|
|
|
|
```yaml
|
|
include:
|
|
- template: Security/SAST.gitlab-ci.yml
|
|
|
|
spotbugs-sast:
|
|
variables:
|
|
FAIL_NEVER: 1
|
|
```
|
|
|
|
### Customize rulesets **(ULTIMATE)**
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/235382) in GitLab 13.5.
|
|
|
|
You can customize the default scanning rules provided by our SAST analyzers.
|
|
|
|
Ruleset customization supports two capabilities:
|
|
|
|
1. Disabling predefined rules
|
|
1. Modifying the default behavior of a given analyzer
|
|
|
|
These capabilities can be used simultaneously.
|
|
|
|
To customize the default scanning rules, create a file containing custom rules. These rules
|
|
are passed through to the analyzer's underlying scanner tools.
|
|
|
|
To create a custom ruleset:
|
|
|
|
1. Create a `.gitlab` directory at the root of your project, if one doesn't already exist.
|
|
1. Create a custom ruleset file named `sast-ruleset.toml` in the `.gitlab` directory.
|
|
1. In the `sast-ruleset.toml` file, do one of the following:
|
|
|
|
- Disable predefined rules belonging to SAST analyzers. In this example, the disabled rules
|
|
belong to `eslint` and `sobelow` and have the corresponding identifiers `type` and `value`:
|
|
|
|
```toml
|
|
[eslint]
|
|
[[eslint.ruleset]]
|
|
disable = true
|
|
[eslint.ruleset.identifier]
|
|
type = "eslint_rule_id"
|
|
value = "security/detect-object-injection"
|
|
|
|
[sobelow]
|
|
[[sobelow.ruleset]]
|
|
disable = true
|
|
[sobelow.ruleset.identifier]
|
|
type = "sobelow_rule_id"
|
|
value = "sql_injection"
|
|
```
|
|
|
|
- Define a custom analyzer configuration. In this example, customized rules are defined for the
|
|
`nodejs-scan` scanner:
|
|
|
|
```toml
|
|
[nodejs-scan]
|
|
description = 'custom ruleset for nodejs-scan'
|
|
|
|
[[nodejs-scan.passthrough]]
|
|
type = "raw"
|
|
value = '''
|
|
- nodejs-extensions:
|
|
- .js
|
|
|
|
template-extensions:
|
|
- .new
|
|
- .hbs
|
|
- ''
|
|
|
|
ignore-filenames:
|
|
- skip.js
|
|
|
|
ignore-paths:
|
|
- __MACOSX
|
|
- skip_dir
|
|
- node_modules
|
|
|
|
ignore-extensions:
|
|
- .hbs
|
|
|
|
ignore-rules:
|
|
- regex_injection_dos
|
|
- pug_jade_template
|
|
- express_xss
|
|
|
|
'''
|
|
```
|
|
|
|
- Provide the name of the file containing a custom analyzer configuration. In this example,
|
|
customized rules for the `gosec` scanner are contained in the file `gosec-config.json`:
|
|
|
|
```toml
|
|
[gosec]
|
|
description = 'custom ruleset for gosec'
|
|
|
|
[[gosec.passthrough]]
|
|
type = "file"
|
|
value = "gosec-config.json"
|
|
```
|
|
|
|
### Using environment variables to pass credentials for private repositories
|
|
|
|
Some analyzers require downloading the project's dependencies in order to
|
|
perform the analysis. In turn, such dependencies may live in private Git
|
|
repositories and thus require credentials like username and password to download them.
|
|
Depending on the analyzer, such credentials can be provided to
|
|
it via [custom environment variables](#custom-environment-variables).
|
|
|
|
#### Using a variable to pass username and password to a private Maven repository
|
|
|
|
If your private Maven repository requires login credentials,
|
|
you can use the `MAVEN_CLI_OPTS` environment variable.
|
|
|
|
Read more on [how to use private Maven repositories](../index.md#using-private-maven-repos).
|
|
|
|
### Enabling Kubesec analyzer
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12752) in GitLab Ultimate 12.6.
|
|
|
|
You need to set `SCAN_KUBERNETES_MANIFESTS` to `"true"` to enable the
|
|
Kubesec analyzer. In `.gitlab-ci.yml`, define:
|
|
|
|
```yaml
|
|
include:
|
|
- template: Security/SAST.gitlab-ci.yml
|
|
|
|
variables:
|
|
SCAN_KUBERNETES_MANIFESTS: "true"
|
|
```
|
|
|
|
### Pre-compilation
|
|
|
|
If your project requires custom build configurations, it can be preferable to avoid
|
|
compilation during your SAST execution and instead pass all job artifacts from an
|
|
earlier stage within the pipeline. This is the current strategy when requiring
|
|
a `before_script` execution to prepare your scan job.
|
|
|
|
To pass your project's dependencies as artifacts, the dependencies must be included
|
|
in the project's working directory and specified using the `artifacts:path` configuration.
|
|
If all dependencies are present, the `COMPILE=false` variable can be provided to the
|
|
analyzer and compilation will be skipped:
|
|
|
|
```yaml
|
|
image: maven:3.6-jdk-8-alpine
|
|
|
|
stages:
|
|
- build
|
|
- test
|
|
|
|
include:
|
|
- template: Security/SAST.gitlab-ci.yml
|
|
|
|
build:
|
|
stage: build
|
|
script:
|
|
- mvn package -Dmaven.repo.local=./.m2/repository
|
|
artifacts:
|
|
paths:
|
|
- .m2/
|
|
- target/
|
|
|
|
spotbugs-sast:
|
|
dependencies:
|
|
- build
|
|
variables:
|
|
MAVEN_REPO_PATH: ./.m2/repository
|
|
COMPILE: "false"
|
|
artifacts:
|
|
reports:
|
|
sast: gl-sast-report.json
|
|
```
|
|
|
|
To allow the analyzer to recognize the compiled artifacts, you must explicitly specify the path to
|
|
the vendored directory. This configuration can vary per analyzer but in the case of Java above, you
|
|
can use `MAVEN_REPO_PATH`. See
|
|
[Analyzer settings](#analyzer-settings) for the complete list of available options.
|
|
|
|
### Available variables
|
|
|
|
SAST can be [configured](#customizing-the-sast-settings) using environment variables.
|
|
|
|
#### Logging level
|
|
|
|
To control the verbosity of logs set the `SECURE_LOG_LEVEL` environment variable. Messages of this logging level or higher are output. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/10880) in GitLab 13.1.
|
|
|
|
From highest to lowest severity, the logging levels are:
|
|
|
|
- `fatal`
|
|
- `error`
|
|
- `warn`
|
|
- `info` (default)
|
|
- `debug`
|
|
|
|
#### Custom Certificate Authority
|
|
|
|
To trust a custom Certificate Authority, set the `ADDITIONAL_CA_CERT_BUNDLE` variable to the bundle
|
|
of CA certs that you want to trust within the SAST environment.
|
|
|
|
#### Docker images
|
|
|
|
The following are Docker image-related variables.
|
|
|
|
| Environment variable | Description |
|
|
|---------------------------|---------------------------------------------------------------------------------------------------------------------------------------|
|
|
| `SECURE_ANALYZERS_PREFIX` | Override the name of the Docker registry providing the default images (proxy). Read more about [customizing analyzers](analyzers.md). |
|
|
| `SAST_ANALYZER_IMAGE_TAG` | **DEPRECATED:** Override the Docker tag of the default images. Read more about [customizing analyzers](analyzers.md). |
|
|
| `SAST_DEFAULT_ANALYZERS` | Override the names of default images. Read more about [customizing analyzers](analyzers.md). |
|
|
|
|
#### Vulnerability filters
|
|
|
|
Some analyzers make it possible to filter out vulnerabilities under a given threshold.
|
|
|
|
| Environment variable | Default value | Description |
|
|
|-------------------------------|--------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
|
| `SAST_EXCLUDED_PATHS` | `spec, test, tests, tmp` | Exclude vulnerabilities from output based on the paths. This is a comma-separated list of patterns. Patterns can be globs, or file or folder paths (for example, `doc,spec` ). Parent directories will also match patterns. |
|
|
| `SEARCH_MAX_DEPTH` | 4 | Maximum number of directories traversed when searching for source code files. |
|
|
| `SAST_BANDIT_EXCLUDED_PATHS` | | Comma-separated list of paths to exclude from scan. Uses Python's [`fnmatch` syntax](https://docs.python.org/2/library/fnmatch.html); For example: `'*/tests/*, */venv/*'` |
|
|
| `SAST_BRAKEMAN_LEVEL` | 1 | Ignore Brakeman vulnerabilities under given confidence level. Integer, 1=Low 3=High. |
|
|
| `SAST_FLAWFINDER_LEVEL` | 1 | Ignore Flawfinder vulnerabilities under given risk level. Integer, 0=No risk, 5=High risk. |
|
|
| `SAST_GOSEC_LEVEL` | 0 | Ignore Gosec vulnerabilities under given confidence level. Integer, 0=Undefined, 1=Low, 2=Medium, 3=High. |
|
|
|
|
#### Analyzer settings
|
|
|
|
Some analyzers can be customized with environment variables.
|
|
|
|
| Environment variable | Analyzer | Description |
|
|
|---------------------------------------|----------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

#### Custom environment variables
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/18193) in GitLab Ultimate 12.5.
|
|
|
|
In addition to the aforementioned SAST configuration variables,
|
|
all [custom environment variables](../../../ci/variables/README.md#custom-environment-variables) are propagated
|
|
to the underlying SAST analyzer images if
|
|
[the SAST vendored template](#configuration) is used.
|
|
|
|
CAUTION: **Caution:**
|
|
Variables having names starting with these prefixes are **not** propagated to the SAST Docker container and/or
|
|
analyzer containers: `DOCKER_`, `CI`, `GITLAB_`, `FF_`, `HOME`, `PWD`, `OLDPWD`, `PATH`, `SHLVL`, `HOSTNAME`.
|
|
|
|
### Experimental features
|
|
|
|
Receive early access to experimental features.
|
|
|
|
Currently, this will enable scanning of iOS and Android apps via the [MobSF analyzer](https://gitlab.com/gitlab-org/security-products/analyzers/mobsf/).
|
|
|
|
To enable experimental features, add the following to your `.gitlab-ci.yml` file:
|
|
|
|
```yaml
|
|
include:
|
|
- template: Security/SAST.gitlab-ci.yml
|
|
|
|
variables:
|
|
SAST_EXPERIMENTAL_FEATURES: "true"
|
|
```
|
|
|
|
## Reports JSON format
|
|
|
|
The SAST tool emits a JSON report file. For more information, see the
|
|
[schema for this report](https://gitlab.com/gitlab-org/security-products/security-report-schemas/-/blob/master/dist/sast-report-format.json).
|
|
|
|
The JSON report file can be downloaded from the CI pipelines page, or the
|
|
pipelines tab on merge requests. For more information see [Downloading artifacts](../../../ci/pipelines/job_artifacts.md).
|
|
|
|
Here's an example SAST report:

|
## Running SAST in an offline environment
|
|
|
|
For self-managed GitLab instances in an environment with limited, restricted, or intermittent access
|
|
to external resources through the internet, some adjustments are required for the SAST job to
|
|
run successfully. For more information, see [Offline environments](../offline_deployments/index.md).
|
|
|
|
### Requirements for offline SAST
|
|
|
|
To use SAST in an offline environment, you need:
|
|
|
|
- GitLab Runner with the [`docker` or `kubernetes` executor](#requirements).
|
|
- A Docker Container Registry with locally available copies of SAST [analyzer](https://gitlab.com/gitlab-org/security-products/analyzers) images.
|
|
- Configure certificate checking of packages (optional).
|
|
|
|
GitLab Runner has a [default `pull policy` of `always`](https://docs.gitlab.com/runner/executors/docker.html#using-the-always-pull-policy),
|
|
meaning the runner tries to pull Docker images from the GitLab container registry even if a local
|
|
copy is available. The GitLab Runner [`pull_policy` can be set to `if-not-present`](https://docs.gitlab.com/runner/executors/docker.html#using-the-if-not-present-pull-policy)
|
|
in an offline environment if you prefer using only locally available Docker images. However, we
|
|
recommend keeping the pull policy setting to `always` if not in an offline environment, as this
|
|
enables the use of updated scanners in your CI/CD pipelines.
|
|
|
|
### Make GitLab SAST analyzer images available inside your Docker registry
|
|
|
|
For SAST with all [supported languages and frameworks](#supported-languages-and-frameworks),
|
|
import the following default SAST analyzer images from `registry.gitlab.com` into your
|
|
[local Docker container registry](../../packages/container_registry/index.md):
|
|
|
|
```plaintext
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/bandit:2
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/brakeman:2
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/eslint:2
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/flawfinder:2
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/gosec:2
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/kubesec:2
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/nodejs-scan:2
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/phpcs-security-audit:2
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/pmd-apex:2
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/security-code-scan:2
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/sobelow:2
|
|
registry.gitlab.com/gitlab-org/security-products/analyzers/spotbugs:2
|
|
```
|
|
|
|
The process for importing Docker images into a local offline Docker registry depends on
|
|
**your network security policy**. Please consult your IT staff to find an accepted and approved
|
|
process by which external resources can be imported or temporarily accessed. Note that these scanners are [updated periodically](../index.md#maintenance-and-update-of-the-vulnerabilities-database)
|
|
with new definitions, so consider if you're able to make periodic updates yourself.
|
|
|
|
For details on saving and transporting Docker images as a file, see Docker's documentation on
|
|
[`docker save`](https://docs.docker.com/engine/reference/commandline/save/), [`docker load`](https://docs.docker.com/engine/reference/commandline/load/),
|
|
[`docker export`](https://docs.docker.com/engine/reference/commandline/export/), and [`docker import`](https://docs.docker.com/engine/reference/commandline/import/).

#### If support for Custom Certificate Authorities are needed
|
|
|
|
Support for custom certificate authorities was introduced in the following versions.
|
|
|
|
| Analyzer | Version |
|
|
| -------- | ------- |
|
|
| `bandit` | [v2.3.0](https://gitlab.com/gitlab-org/security-products/analyzers/bandit/-/releases/v2.3.0) |
|
|
| `brakeman` | [v2.1.0](https://gitlab.com/gitlab-org/security-products/analyzers/brakeman/-/releases/v2.1.0) |
|
|
| `eslint` | [v2.9.2](https://gitlab.com/gitlab-org/security-products/analyzers/eslint/-/releases/v2.9.2) |
|
|
| `flawfinder` | [v2.3.0](https://gitlab.com/gitlab-org/security-products/analyzers/flawfinder/-/releases/v2.3.0) |
|
|
| `gosec` | [v2.5.0](https://gitlab.com/gitlab-org/security-products/analyzers/gosec/-/releases/v2.5.0) |
|
|
| `kubesec` | [v2.1.0](https://gitlab.com/gitlab-org/security-products/analyzers/kubesec/-/releases/v2.1.0) |
|
|
| `nodejs-scan` | [v2.9.5](https://gitlab.com/gitlab-org/security-products/analyzers/nodejs-scan/-/releases/v2.9.5) |
|
|
| `phpcs-security-audit` | [v2.8.2](https://gitlab.com/gitlab-org/security-products/analyzers/phpcs-security-audit/-/releases/v2.8.2) |
|
|
| `pmd-apex` | [v2.1.0](https://gitlab.com/gitlab-org/security-products/analyzers/pmd-apex/-/releases/v2.1.0) |
|
|
| `security-code-scan` | [v2.7.3](https://gitlab.com/gitlab-org/security-products/analyzers/security-code-scan/-/releases/v2.7.3) |
|
|
| `sobelow` | [v2.2.0](https://gitlab.com/gitlab-org/security-products/analyzers/sobelow/-/releases/v2.2.0) |
|
|
| `spotbugs` | [v2.7.1](https://gitlab.com/gitlab-org/security-products/analyzers/spotbugs/-/releases/v2.7.1) |
|
|
|
|
### Set SAST CI job variables to use local SAST analyzers
|
|
|
|
Add the following configuration to your `.gitlab-ci.yml` file. You must replace
|
|
`SECURE_ANALYZERS_PREFIX` to refer to your local Docker container registry:
|
|
|
|
```yaml
|
|
include:
|
|
- template: Security/SAST.gitlab-ci.yml
|
|
|
|
variables:
|
|
SECURE_ANALYZERS_PREFIX: "localhost:5000/analyzers"
|
|
```
|
|
|
|
The SAST job should now use local copies of the SAST analyzers to scan your code and generate
|
|
security reports without requiring internet access.
|
|
|
|
### Configure certificate checking of packages
|
|
|
|
If a SAST job invokes a package manager, you must configure its certificate verification. In an
|
|
offline environment, certificate verification with an external source is not possible. Either use a
|
|
self-signed certificate or disable certificate verification. Refer to the package manager's
|
|
documentation for instructions.
|
|
|
|
## Troubleshooting
|
|
|
|
### `Error response from daemon: error processing tar file: docker-tar: relocation error`
|
|
|
|
This error occurs when the Docker version that runs the SAST job is `19.03.0`.
|
|
Consider updating to Docker `19.03.1` or greater. Older versions are not
|
|
affected. Read more in
|
|
[this issue](https://gitlab.com/gitlab-org/gitlab/-/issues/13830#note_211354992 "Current SAST container fails").
|
|
|
|
### Getting warning message `gl-sast-report.json: no matching files`
|
|
|
|
For information on this, see the [general Application Security troubleshooting section](../../../ci/pipelines/job_artifacts.md#error-message-no-files-to-upload).
|
|
|
|
### Limitation when using rules:exists
|
|
|
|
The [SAST CI template](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Security/SAST.gitlab-ci.yml)
|
|
uses the `rules:exists` parameter. For performance reasons, a maximum number of matches are made
|
|
against the given glob pattern. If the number of matches exceeds the maximum, the `rules:exists`
|
|
parameter returns `true`. Depending on the number of files in your repository, a SAST job might be
|
|
triggered even if the scanner doesn't support your project. For more details about this issue, see
|
|
the [`rules:exists` documentation](../../../ci/yaml/README.md#rulesexists).
