Additions to consider:
- Compartmentalize devices/identities: Use separate devices or profiles for different activities (e.g., one for work, one for sensitive stuff)
- Encrypt everything: Use tools like VeraCrypt/PicoCrypt for storage and PGP for email.
- Metadata
- Physical OPSEC: Cover webcams, disable mics when not in use, and be mindful of shoulder surfers or CCTV when accessing sensitive info.
