Containers have become a cornerstone of modern software development. They allow developers to package applications with all necessary dependencies and run them consistently across environments, drastically reducing headache around environment setup. However, this convenience also introduces new security challenges.

Securing containers involves ensuring the integrity, confidentiality, and availability of the containerized application throughout its lifecycle—from image creation to deployment and runtime, to keep applications and their environments free from vulnerabilities, misconfigurations, and malicious activity.
