Security teams can't protect what they don't know about. But it is not enough to just understand what they have within their organizations' environment. Defenders also need to put themselves in an adversary's shoes to understand which systems are likely to be targeted and how the attack would be carried out. Technologies such as attack surface management and attack path modeling make it possible for security teams to gain visibility into which assets adversaries can see and how they might gain access. With attack surface management, organizations are continuously discovering, classifying, and monitoring the IT infrastructure.
