Concepts
Risk
How likely something bad is to happen and how much it would hurt. Good security spends effort where both are high.
A risk combines a chance and a cost. A stolen social media password is annoying; a stolen email password can lead to losing many accounts and some money, so it deserves more care first.
You cannot remove all risk and do not need to. You reduce it where it matters, accept a little where it does not, and prepare for the rest with a backup and a plan.
What to do
- Rank your accounts by how much losing each would hurt.
- Protect the top of the list first.
- Have a backup for what you cannot afford to lose.
