GitHub Security

A leaked API key in a commit history, a vulnerable dependency pulled in without review, or a misconfigured Terraform file merged straight to production — these are some of the most common ways breaches start, and they all happen inside the repository, long before an attacker ever touches your live infrastructure.

Why Repository-Level Security Matters

Your source control is where every vulnerability begins its life — a hardcoded credential, an insecure default, a dependency with a known CVE. Catching these at the commit or pull-request stage is dramatically cheaper than catching them after they've shipped: no incident response, no rotation under pressure, no customer notification.

What We Check

Alastor InfoSec's GitHub Security coverage runs continuously against every connected repository:

• Secret scanning — API keys, credentials, private keys, and tokens committed to code or accidentally left in commit history, including secrets buried in old commits that a simple grep of HEAD would miss.
• Dependency and supply chain scanning (SCA) — known-vulnerable packages, license risk, and dependency confusion attacks, flagged before merge.
• Infrastructure as Code (IaC) checks — Terraform, CloudFormation, and Kubernetes manifests reviewed for insecure defaults, overly permissive IAM roles, and public-by-default resources.
• Branch protection and access review — who can push directly to protected branches, whether required reviews are actually enforced, and where CI/CD tokens have broader scope than they need.
• CI/CD pipeline security — build pipelines reviewed for injectable steps, exposed secrets in logs, and third-party Actions running with excessive permissions.

Built Into Your Existing Workflow

GitHub Security checks run on every commit and pull request, surfacing findings directly where your engineers already work rather than in a separate portal they have to remember to check. This pairs naturally with our Code Security module for deeper application-level static analysis, giving you commit-level hygiene and code-level vulnerability detection from the same pipeline.

Who Needs This

Any engineering team shipping code through GitHub — which is to say, nearly every modern software team — benefits from continuous repository scanning rather than relying on developers to remember secret hygiene manually. This is especially important for teams under SOC 2 or ISO 27001 audit scope, where source control access controls and secret management are standard control points auditors will ask about directly.
