Trivy. A Simple and Comprehensive Vulnerability Scanner for Containers.

Using Trivy:

Trivy is a mature and comprehensive open source tool from Aqua Security that supports scanning multiple sources, from file systems to containers and VMs. Trivy also looks beyond vulnerabilities, to scan licenses, secrets, infrastructure as code misconfiguration, and more.

I would suggest to think about the thread model that you are facing so you can have a better mental model of the weak points of your environment. The very very big majority of these attacks will be automated probing for publicly known vulnerabilities or default credentials. That means the maintainers of the software you are running and the channels on which their updates are shipped to you and deployed are very important factors. For software that is not installed from a trusted and well maintained source (e.g. Ubuntus main repository), you want to make extra sure that vulnerabilities are updated. E.g. your deployed docker containers might contain security issues, you can run checks on these with tools like trivy. The same is also true for appliances, in case your router or firewall contains a software vulnerability, how will you be notified and how will the required updates be deployed?

2. Terrascan: https://github.com/tenable/terrascan Terrascan detects security vulnerabilities and compliance violations across your IaC. Supports multiple cloud providers, ensuring that your infrastructure complies with security best practices.

Terrascan - Scan for Infrastructure-as-Code vulnerabilities

(https://runterrascan.io/) They seem to like it, don't have a ton of my own experience though.

Nessus Expert - newer offering. Nessus Pro + terrascan + basic external attack surface mapping. Doesn’t scan from the internet, but shows you all your public domains, DNS, etc so you can pick what you want to scan/ fix

It is always a good practice to scan your Kubernetes deployment or Helm chart before deploying. We can use Checkov to scans Kubernetes manifests and identifies security and configuration issues. It also supports Helm chart scanning. We can also use terrascan and kubeLinter to scan the Kubernetes manifest.
