Access control. The Carbon Black researchers believe it is "highly plausible" that this threat actor sold this information on an "access marketplace" to others who could then launch their own attacks by remote access. A central authority regulates access rights and organizes them into tiers, which uniformly expand in scope. Without authentication and authorization, there is no data security, Crowley says. In some cases, authorization may mirror the structure of the organization, while in others it may be based on the sensitivity level of various documents and the clearance level of the user accessing those documents. To prevent unauthorized access, organizations require both preset and real-time controls. The goal is to provide users only with the data they need to perform their jobsand no more. Modern IT environments consist of multiple cloud-based and hybrid implementations, which spreads assets out over physical locations and over a variety of unique devices, and require dynamic access control strategies. It consists of two main components: authentication and authorization, says Daniel Crowley, head of research for IBMs X-Force Red, which focuses on data security. In general, access control software works by identifying an individual (or computer), verifying they are who they claim to be, authorizing they have the required access level and then storing their actions against a username, IP address or other audit system to help with digital forensics if needed. Electronic access control (EAC) is the technology used to provide and deny physical or virtual access to a physical or virtual space.
