Definition
Adaptive Cyber Defense (ACD in short) covers the general area of cyber security that is outside of its classical focus, namely, protection and detection. Specifically, ACD incorporates adaptive and autonomous responses – proactive, or reactive, to detected attacks or observed cyber incidents – that dynamically change some combination of the configuration of the protected system, its behavior, and the security policies and mechanisms that govern the system, with the aim of achieving tolerance, survivability, and resilience to future attacks.
Background
The initial focus of cyber security was protection – security mechanisms and techniques focused on preventing bad things from happening. Typically, strict enforcement of well-designed static policies prevented any attempts to violate, breach, or bypass the security controls (Lipner 2015). As systems grew more complex, versatile, geographically distributed,...
