Software Defined Perimeter
Software Defined Perimeter (SDP) is a security framework that creates a dynamic, identity-centric boundary around network resources, hiding them from unauthorized users. It operates on a 'default deny' principle, granting access only after device and user authentication, and establishes encrypted connections for authorized sessions. This approach enhances security by reducing the attack surface and preventing lateral movement within networks.
Developers should learn SDP when building or securing applications in cloud, hybrid, or zero-trust environments, as it provides robust protection against network-based attacks like DDoS and data breaches. It's particularly useful for securing remote access, IoT deployments, and compliance-sensitive industries like finance or healthcare, where granular access control is critical.
