I remember filtering for newly spawned processes, but I’m uncertain if we need to specify the container ID for Nginx in the command.

I feel confident about using Falco, but I might mix up the timestamp format. I hope it's just the standard ISO format.

I think we did a similar exercise where we had to log incidents, but I can't recall if we needed to specify the output format exactly like that.

This seems like a good opportunity to demonstrate my Falco skills. I'll make sure to thoroughly analyze the container behavior for the full 20 seconds, and capture all the relevant process-related incidents in the required format. Shouldn't be too difficult if I plan it out carefully.

No problem, I've used Falco before for this kind of task. I'll start by launching the Nginx container, then run Falco with the appropriate process-related filters. Saving the incident data to the specified file should be easy enough.

Hmm, I'm a bit unsure about how to use Falco effectively here. I'll need to review the documentation to make sure I understand the right commands and filters to use. Capturing the incident data in the right format will also be important.

Okay, this seems straightforward. I'll need to set up Falco on the container, run it for at least 20 seconds, and capture the incident data to the specified file. The key will be using the right filters to detect newly spawning and executing processes.
