Although organizations realize the need to upgrade their approach to user access control. The deployment of existing technologies is holding back the introduction of Software Defined Perimeter (SDP). A recent report carried out by the Cloud Security Alliance (CSA) on the “State of Software Defined Perimeter” states that the main barrier to adopting SDP is the existing in-place security technologies.
The foundations that support our systems are built with connectivity and not security as an essential feature. TCP connects before it authenticates. Security policy and user access based on IP lack context and allow architectures that exhibit overly permissive access. Most likely, this will result in a brittle security posture.
