emailOpenSSF Scorecard assesses open source projects for security risks through a series of automated checksIt was created by OSS developers to help improve the health of critical projects that the community depends on.
You can use it to proactively assess and make informed decisions about accepting security risks within your codebase. You can also use the tool to evaluate other projects and dependencies, and work with maintainers to improve codebases you might want to integrate.
Scorecard is an automated tool that assesses a number of important heuristics ("checks") associated with software security and assigns each check a score of 0-10. You can use these scores to understand specific areas to improve in order to strengthen the security posture of your project. You can also assess the risks that dependencies introduce, and make informed decisions about accepting these risks, evaluating alternative solutions, or working with the maintainers to make improvements.

The Package Analysis project analyses the capabilities of packages available on open source repositories. The project looks for behaviors that indicate malicious software:
-
What files do they access?
-
What addresses do they connect to?
-
What commands do they run?

GuardDog is a CLI tool to Identify malicious PyPI and npm packages.
GuardDog is a CLI tool that allows to identify malicious PyPI and npm packages or Go modules. It runs a set of heuristics on the package source code (through Semgrep rules) and on the package metadata.
GuardDog can be used to scan local or remote PyPI and npm packages or Go modules using any of the available heuristics.

KubeClarity is a tool for detection and management of Software Bill Of Materials (SBOM) and vulnerabilities of container images and filesystems. It scans both runtime K8s clusters and CI/CD pipelines for enhanced software supply chain security.
Sigstore is an open source project for improving software supply chain security. The Sigstore framework and tooling empowers software developers and consumers to securely sign and verify software artifacts such as release files, container images, binaries, software bills of materials (SBOMs), and more. Signatures are generated with ephemeral signing keys so there’s no need to manage keys. Signing events are recorded in a tamper-resistant public log so software developers can audit signing events.

Dependency-Check is a Software Composition Analysis (SCA) tool that attempts to detect publicly disclosed vulnerabilities contained within a project’s dependencies. It does this by determining if there is a Common Platform Enumeration (CPE) identifier for a given dependency. If found, it will generate a report linking to the associated CVE entries.
A simple measure of software dependency freshness. It is a single number telling you how up-to-date your dependencies are.
Supply-chain Levels for Software Artifacts, or SLSA ("salsa").
SLSA is a specification for describing and incrementally improving supply chain security, established by industry consensus. It is organized into a series of levels that describe increasing security guarantees.
It’s a security framework, a checklist of standards and controls to prevent tampering, improve integrity, and secure packages and infrastructure. It’s how you get from "safe enough" to being as resilient as possible, at any link in the chain.
