How does Docker reduce security?
It downloads things without checking signatures by default. And even if you enable DCT, it TOFUs every key without even asking or checking against a WoT
Basically, using docker means you could run malicious code (arbitrary code execution) in your container because it doesn’t verify what it downloads.
The bright side is, that you run it in a container. Beware of privileged mode, don’t give it unnecessary mounts or networks, and there’s very little some malicious code can do.
If you’re using it for a build system, tough luck but you need to manage the keys to avoid TOFU, and ideally pull from your own registry.
