log4shell VS trivy

I hope more organizations and governments do this. They had an excellent resource for Log4J. https://github.com/NCSC-NL/log4shell

A few

Nice list - https://github.com/NCSC-NL/log4shell/blob/main/software/README.md

There are various tools, nicely again enumerated by NCSC-NL at their Github repository with which you can detect whether you are vulnerable. See which one you like best given the situation you are in.

Check what other software you are running and see if the software is vulnerable according to the list published by the NCSC-NL. CISA.gov has a similar registry.

There are multiple lists of software, the one I use is by the Dutch Cyber Security Center: https://github.com/NCSC-NL/log4shell/tree/main/software Everyday I cross reference on new changes and see if it effects my list. The list can be quite extensive and you might miss the most obvious ones like you FW, switches, SAN or some print software.

NCSC-NL has a researched list of specific vulnerabilities.

4. Trivy: https://github.com/aquasecurity/trivy Trivy is a versatile tool that scans for vulnerabilities in your containers, and also checks for vulnerabilities in your application dependencies.

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?
