Recently, I’ve been learning more about this subject. Today I came across the Decentralization Scoring System and it slapped me across the face.
Technical ease of running your own backend. Full points for Docker/simple setup with good docs.
Oof, they neef a column for security to mark back down all the services that use docker.
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.
A container that has access to all the data on the database. All the users data is compromised. And the attacker can execute malicious JavaScript on the users.
There’s nothing bright about using docker. Its a huge risk.
