40. Awareness: Supply Chain Security

Supply chain attacks target your build process or dependencies.
Protect your development pipeline with signature verification and strict sources.

Example

# 40. Verify package signatures and hashes
pip install --require-hashes -r requirements.txt

# 40. Use trusted repositories only
pip config set global.index-url https://pypi.org/simple

✅ Lesson: Verify integrity, use trusted registries, and restrict write access to your deployment pipeline.
