The sprawling and complex set of subjects we call cyber security can all be tied to one fundamental concept — time. The time it takes a cyberattack to penetrate, the time from initial compromise to lateral movement across the network, the time it takes for an attack to be detected, to be analyzed, to be responded to and remediated.
Time is one of seven base quantities in the International System of Units upon which all other measures are constructed. No surprise then that it’s the single most important factor in cybersecurity program success.
Industry research indicates that within just two hours, on average, attackers can break out from the initial compromised endpoint and move to other machines in the network. Assuming machine zero is not the end game, that’s the window companies have to detect and stop an attack before damage
