Background for this topic.
Source code is the human-readable text programmers write in a language such as Python, Java, or C before it is compiled or interpreted into a running program. It defines the program’s logic, data handling, and interactions with operating systems, networks, and other services. Source code may include application code, scripts, and configuration that controls software behavior.
In security, exposed or improperly protected repositories can disclose credentials, private keys, internal endpoints, or details that help attackers find exploitable flaws. Vulnerabilities may also enter through unsafe coding patterns, outdated dependencies, or malicious changes to code and build pipelines. Defenses include least-privilege repository access, secret scanning, peer review, static analysis, dependency and software-composition checks, and integrity controls for releases. Preserving commit history and build provenance helps investigators determine what changed and whether delivered software matches reviewed source.
