Software Defined Perimeter

The Software-Defined Perimeter (SDP) architecture provides the ability to deploy network security perimeter functionality where needed dynamically and flexibly to isolate applications and services deployed and accessed on networks. An SDP implementation hides assets from unauthorized entities, establishes trust prior to allowing connections, and manages the system via separate control and data planes. With SDP, organizations can achieve the goals of Zero Trust, improving their security effectiveness and resiliency by moving away from traditional, and largely ineffective perimeter-centric security models. WE will assess and deploy SDP in accordance with the Cloud Security Alliance Specification version 2.

Software Defined Perimeter

TechnoGen Cyber Security designs enterprise cybersecurity architectures that deploy a Software- defined perimeter (SDP) framework to control access to resources based on identity and a need-to- know model, in which device posture and identity are verified before access to application infrastructure is granted. SDP mitigates the most common network-based attacks such as server scanning, denial of service, SQL injection, operating system and application vulnerability exploits, man-in-the-middle, pass-the-hash, pass-the-ticket, and other attacks.

How do SDPs relate to Zero Trust security?

As the name implies, there is no trust in Zero Trust security; no user, device, or network is considered trustworthy by default. Zero Trust security is a security model that requires strict identity verification for every person and device trying to access internal resources, no matter whether they are sitting inside or outside the network perimeter (or, the software-defined perimeter).

An SDP is one way to implement Zero Trust security. Users and devices must both be verified before they can connect, and they have only the minimum network access they need. No device, not even a CEO's laptop, can form a network connection with a resource it is not authorized to use.
