Question
If we are using the time-based model of controls, what equation are we using?
Solution
The equation used in the time-based model of controls is P > D + R.
Here's what each term represents:
- P stands for the time it takes for an attacker to break through the preventive controls.
- D stands for the time it takes to detect that an attack is happening.
- R stands for the time it takes to respond to the attack and restore systems to normal.
The goal of this model is to ensure that the sum of detection and response time (D + R) is less than the time it takes for an attacker to break in (P). This way, the attack can be mitigated before it succeeds.
