Its visualization tools permit you to view the security status of most your AWS services within a window.
In order to integrate our own scanner, the only real image we have to build ourselves may be the image used for the scanning process itself.

Vulnerabilities In Container Images

When we do vulnerability or penetration testing in a live production system, we say we’re doing reactive security.
We’re in a race — trying to find the issues before other people can exploit them.
In the Ecosystem section you will find how Trivy works together other tools and applications that you may already use.

  • of the modern practices used increasingly by software development teams as the DevOps culture is growing in popularity.
