System and endpoint hardening

Secure computers, servers and phones.

📖 Key ideas

  1. Patch OS and software promptly.
  2. Use endpoint protection (antivirus/EDR).
  3. Remove unused software and services.
  4. Use strong unique passwords with a password manager and MFA.
  5. Encrypt disks and enable screen locks.
💡 Real-life example: Hardening is closing every unused window and door in a house.
