Salus (Security Automation as a Lightweight Universal Scanner), named after the Roman goddess of protection, is a tool for coordinating the execution of security scanners. You can run Salus on a repository via the Docker daemon and it will determine which scanners are relevant, run them and provide the output. Most scanners are other mature open source projects which we include directly in the container.
Salus is particularly useful for CI/CD pipelines because it becomes a centralized place to coordinate scanning across a large fleet of repositories. Typically, scanners are configured at the repository level for each project. This means that when making org wide changes to how the scanners are run, each repository must be updated. Instead, you can update Salus and all builds will instantly inherit the change.
Salus supports powerful configuration that allows for global defaults and local tweaks. Finally, Salus can report metrics on each repository, such as what packages are included or what concerns exist. These reports can be centrally evaluated in your infrastructure to allow for scalable security tracking.
# Navigate to the root directory of the project you want to run Salus on
cd /path/to/repo
# Run the following line while in the root directory (No edits necessary)
docker run --rm -t -v $(pwd):/home/repo coinbase/salus- Bandit - Execution of Bandit 1.6.2, looks for common security issues in Python code.
- Brakeman - Execution of Brakeman 4.10.0, looks for vulnerable code in Rails projects.
- semgrep - Execution of
semgrep0.62.0 which looks for semantic and syntactical patterns in code at the AST level. - BundleAudit - Execution of bundle-audit 0.8.0, looks for CVEs in ruby gem dependencies.
- Gosec - Execution of gosec 2.11.0, looks for security problems in go code.
- npm audit - Execution of
npm audit6.14.8 which looks for CVEs in node module dependencies. - yarn audit - Execution of
yarn audit1.22.0 which looks for CVEs in node module dependencies. - PatternSearch - Execution of
sift0.9.0, looks for certain strings in a project that might be dangerous or could require that certain strings be present. - Cargo Audit - Execution of Cargo Audit 0.14.0 Audit Cargo.lock files for crates with security vulnerabilities reported to the RustSec Advisory Database
Salus also parses dependency files and reports which libraries and versions are being used. This can be useful for tracking dependencies across your fleet.
Currently supported languages are:
- Ruby
- Node.js (Javascript)
- Python
- Go
- Rust
Salus is designed to be highly configurable so that it can work in many different types of environments and with many different scanners. It supports environment variable interpolation and cascading configurations, and can read configuration and post reports over HTTP.
Sometimes it's necessary to ignore certain CVEs, rules, tests, groups, directories, or otherwise modify the default configuration for a scanner. The docs/scanners directory explains how to do so for each scanner that Salus supports.
If you would like to build custom scanners or support more languages that are not currently supported, you can use this method of building custom Salus images.
Salus can be integrated with CircleCI by using a public Orb. All Salus configuration options are supported, and defaults are the same as for Salus itself.
Example CircleCI config.yml:
version: 2.1
orbs:
salus: federacy/[email protected]
workflows:
main:
jobs:
- salus/scan
Salus can also be used with Github Actions.
Example .github/workflows/main.yml:
on: [push]
jobs:
salus_scan_job:
runs-on: ubuntu-latest
name: Salus Security Scan Example
steps:
- uses: actions/checkout@v1
- name: Salus Scan
id: salus_scan
uses: federacy/[email protected]
For your given CI, update the config file to run salus. In circle, it will look like this:
docker run --rm -t -v $(pwd):/home/repo coinbase/saluscoinbase/salus pulls the docker image
Contribution to this project is extremely welcome and it's our sincere hope that the work we've done to this point only serves as a foundation for allowing the security/development communities as a whole to come together to improve the security of everyone's infrastructure.
