You want to have a file specifying your dependencies, and a file specifying your currently locked set - e.g. Cargo.toml and Cargo.lock, or Gemfile and Gemfile.lock, or pyproject.toml and poetry.lock

You'll then want tooling to periodically update your locked dependencies, so that you pick up fixes to security vulnerabilties. That wants to go through your CI.

This is a double edged sword.

Because on one hand, you do pick up hotfix patches, but on the other hand, you are possibly bit more exposed to supply chain attacks.

Any ideas on how to balance that out? Or should we just not consider supply chain attacks to be a real threat?

Mirror the upstream, and as part of mirroring, do an automated security analysis of your dependencies.

Sandbox your dependencies.

Run automated security vulnerability testing on your program, looking for rogue behaviour.

Require code signatures on dependencies.

Identity security critical components and audit them.
