What defines a scanner in the context of GitLab Security Scanner?

In the context of GitLab Security Scanner, the correct definition of a scanner is that it refers to a command line tool that generates a report. This aligns with the functionality of many security scanners that integrate with CI/CD pipelines, where they run in a command-line environment to analyze code for vulnerabilities and security issues.

Command line tools are particularly advantageous in a DevOps or CI/CD environment because they can be easily automated and integrated into existing workflows. When a scan is completed, these tools typically produce detailed reports that summarize the findings, making it easier for development teams to identify and address security vulnerabilities in their code.

Additionally, many modern security scanners in the GitLab ecosystem are designed to work seamlessly within the GitLab environment, allowing teams to incorporate security testing into their development processes without requiring a separate user interface or web service for each scan. The nature of command line tools also emphasizes efficiency and speed, which is crucial in continuous integration scenarios where rapid feedback is essential.

This function distinguishes it from other types of tools, such as web services that might require additional configuration or user interface-based tools that might not fit seamlessly into an automated workflow.
