step-security/harden-runner

• highreadme#1

  Reposition the README's opening paragraph to clearly state its unique category

  Why:

  CURRENT

  Corporate laptops and production servers typically have robust security monitoring in place to reduce risk and meet compliance requirements. However, CI/CD runners, which handle sensitive information like secrets for cloud environments and create production builds, often lack such security measures. This oversight has led to significant supply chain attacks, including the SolarWinds and Codecov breaches. Traditional security monitoring and EDR solutions are ineffective for CI/CD runners due to their ephemeral nature. These tools also lack the necessary context to correlate events with specific workflow runs in a CI/CD environment. StepSecurity Harden-Runner addresses this gap by providing security monitoring tailored for CI/CD runners, with support for Linux, Windows, and macOS runners. This approach brings CI/CD runners under the same level of security scrutiny as other critical systems, addressing a significant gap in the software supply chain.

  COPY-PASTE FIX

  StepSecurity Harden-Runner is a specialized CI/CD security agent that functions as an EDR (Endpoint Detection and Response) solution specifically designed for GitHub Actions runners. Unlike traditional EDRs or general supply chain security tools, Harden-Runner provides real-time monitoring of network egress, file integrity, and process activity on ephemeral runners, detecting threats tailored to the CI/CD environment.

  Add a 'Why Harden-Runner?' or 'Comparison' section to the README

  Why:

  COPY-PASTE FIX

  Copy

  Add a new section titled 'Why Harden-Runner?' or 'Comparison to Other Tools' that explicitly contrasts its capabilities with general vulnerability scanners (e.g., Trivy), runtime security tools (e.g., Falco), or broad EDR platforms, emphasizing its unique focus on GitHub Actions runner-specific EDR. For example: 'While tools like Trivy scan for vulnerabilities and Falco monitors general runtime activity, Harden-Runner provides an EDR-like capability *within* your GitHub Actions runners, offering granular, real-time threat detection and policy enforcement specifically for CI/CD workflows.'

  actions, egress-filtering, github-actions, hardening, network-security, runners, runtime-security, security-hardening, supply-chain-security

  COPY-PASTE FIX

  Copy

  Add `ci-cd-security-agent` and `github-actions-edr` to the existing topics.
