falcosidekick VS trivy

How does Falco do that? Based on a set of rules that Falco interprets at startup time, it waits for events and syscalls that would trigger one of those rules. When a rule is triggered, Falco raises an alert and, thanks to applications like Falco Sidekick, allows teams to react accordingly.

Falco can emit its findings to stdout, a file, syslog, or custom endpoints with "Program Output" using bash. Alternatively, Falcosidekick is an extra app that receives Falco alerts from multiple clusters and forwards them to a variety of outputs concurrently. Falcosidekick has a large number of custom destinations, so it may reduce the need to write custom integrations for existing destinations like a SIEM.

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?
