In the latest case were many security specialists, DevOps searching CVE-2021– connected with a common Java logging library.
TAP automagically integrates with Grype as the source code and image scanner, nonetheless it also has beta support currently for Snyk and for Carbon Black .
Nowadays, a containerized solution is really a de facto standard in the cloud-native application development world.
Tools like Docker, Containers, CRI-O, and Kubernetes are on-trend.
Millions of development and architecture teams select a container-based treatment for build their product.

Trivy Open Source Scanner For Container Images – Just Download And Run!
The goals of the team and management – Especially in larger teams, it could happen that the goals of the management and person deploying and using the security scanner aren’t aligned.
You must be clear about why your team really wants to use a security scanner in the first place.
Misconfiguration scans can expose our application stack to unnecessary security risks.

Using agents, the scanners are automatically integrated into your workflows to ingest and normalize data with maximum ease, generating results that can be viewed through a web interface.
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.

Extending Trivy
One of the more serious concerns arises when the container runtimes that launch and manage containers — software such as containerd, CRI-O, and rkt themselves contain vulnerabilities.

Grep the results and you may find the exact version of the component the image has.
It’s often useful to exec into a running container with the image and run the binary to check on versions.
But that doesn’t mean we can’t use every tool at hand to reduce the odds of having a security breach.
Trivy config –exit-code 1 –severity MEDIUM,HIGH,CRITICAL .
Our demo project doesn’t include any IaC files, but this is where the Trivy job would go if it did.
