What is Docker Scout and how to use it for image vulnerability scanning?

The Docker Scout tool is a modern container security analysis solution designed for deep scanning of built image layers for known vulnerabilities in system packages and third-party application libraries.

With the constant emergence of new security threats, developers need to regularly check used dependencies for zero-day vulnerabilities, and integrating the scanner directly into the build environment allows identifying problem areas even before the code reaches the production environment.

The analysis process consists of building a detailed dependency map and comparing each detected software version with up-to-date global vulnerability databases, after which a detailed report is generated indicating the criticality of the found problems and recommendations for fixing them.

To effectively use this tool, developers typically perform the following steps:

Using such specialized security utilities becomes an integral part of the software development life cycle, ensuring a high level of security for finished products at all stages of their delivery.
