====== OpSec ======

//OpSec// is shorthand for //Operational Security//.

It is a set of behavioural principles that are designed to keep you and your data safe.

===== What to do? =====

This is a very brief list.

0. Security is a process, not a product. Nothing is ever 100% safe.

  - Keep your software up to date.
  - Use strong and different passwords.
  - Always have a pair of eyes on your hardware (it does not have to be your pair!).
  - Lock your screen when you leave your computer/phone.
  - Make sure to use encrypted connections (watch out for the "http**s**:" in the address bar.
  - Encrypt your hard disk.
  - Don't open links or attachments from emails.

  * **C**onfidentiality,
  * **I**ntegrity, and
  * **A**vailability

are three things you might want to have, and which are achieved through e.g. encrypting messages, signing messages, and using services without a single point of failure.
