Cryptzone: What is a Software-Defined Perimeter?
Download as PPTX, PDF1 like1,329 views
A Software-Defined Perimeter (SDP) is a security model that creates secure 1:1 connections between users and data by authenticating users before granting access. Utilizing mutual TLS and real-time policy enforcement, SDP architecture involves controllers, gateways, and clients interacting securely, while protecting cloud and network resources. This approach enhances security by removing the need for traditional defenses and focusing on identity-centric policies.

- 1. What is a Software-Defined Perimeter?
- 2. What is a Software-Defined Perimeter (SDP)? Simple. Secure. Dynamic. A new network security model that dynamically creates 1:1 network connections between users and the data they access 2
- 3. How Does a SDP Work? Software-Defined Perimeter Traditional TCP/IP Not Identity Centric – Allows Anyone Access Identity-Centric – Only Authorized Users “Connect First, Authenticate Second” “Authenticate First, Connect Second” 3

SDP Architecture • Controller is the authentication point, containing user access policies • Clients are securely onboarded • All connections based on mutual TLS connectivity • Traffic is securely tunneled from Client through Gateway 4 Protected Applications SDP Controller SDP Gateway (Accepting Host) SDP Client (Initiating host) PKI Identity Management Policy Model
