Security - Concept
Security control
A specific measure put in place to reduce a security risk
What's it for?
Reduces a particular security risk through a specific safeguard or check.
For example…
A second login check makes a stolen password less useful.
MFA is a security control that reduces the chance a stolen password alone can give an attacker access
Think of it like…
Seatbelts and airbags: each control handles a different part of the risk, and none replaces common sense
