lynis VS grype

Linux has (free) tools to improve security and detect/remove malware: Lynis,Chkrootkit,Rkhunter,ClamAV,Vuls,LMD,radare2,Yara,ntopng,maltrail,Snort,Suricata...

What I would do in your place is run this https://github.com/CISOfy/lynis and follow some of the instructions.

Linux security audit scanner

Besides pointing pentester tools like metasploit at yourself, there are some nice scanners out there.

Using Grype:

In the lab to follow, we'll see how vulnerability scanning can be conveniently achieved with Grype and how various systematic techniques can be applied to start securing our microservices at the container image level.

Scanning your container images for vulnerabilities is a good approach. But this scanning is not one time job, it should be done regularly (weekly, monthly, etc.) You need to follow vulnerability reports and fix all of the vulnerabilities as soon as possible. I recommend some open-source tools that could be useful: Trivy, Docker-Bench, Grype.

Grype is another popular open source tool from Anchore. Working with SBOM files, Grype scans container images and filesystems for vulnerabilities. Grype supports different output formats for vulnerabilities and custom templates for output.

Grype will allow you to scan a container to see if you have any vulnerable packages.

I have a Docker image that I built with python:3.10-slim. I wanted to start scanning my images so I'm using grype to do it locally with the plan to introduce it to a GitHub Actions workflow. After I ran the scanner, there was one critical issue found: libdb5.3 CVE-2019-8457. I looked it up and it seems to be an issue with sqlite.
