Traditional enterprise security models were built around protecting a trusted, internal network from external threats. Data was safely contained within a clearly defined perimeter.
As businesses adopt more cloud-based systems and mobile working becomes commonplace, that perimeter has been radically redefined or indeed removed altogether.
Modern employees are often untethered, working outside office walls and connecting to business applications via personal devices and different networks. Consequently, enterprises no longer have distinct boundaries.
Administrators of modern environments face new security challenges as they attempt to secure employees’ access to the new enterprise network.
