Cryptzone: What is a Software-Defined Perimeter?
- 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
- 4. 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
- 5. SDP in Action 5 Protected Applications AppGate Controller AppGate Gateway AppGate Client Control Channel Encrypted, Tunneled Data Channel
- 6. SDP in Action 6 Controller uses PKI and IAM to establish trust Controller is an authentication point and policy store System is administered via graphical admin console 1 Protected Applications AppGate Controller AppGate Gateway AppGate Client Control Channel Encrypted, Tunneled Data Channel PKI Identity Management Policy Model Graphical Admin Console 1

SDP in Action 7 Controller uses PKI and IAM to establish trust Controller is an authentication point and policy store System is administered via graphical admin console Gateways protect cloud and network resources Application network traffic passes through Gateway 1 2 Protected Applications AppGate Controller AppGate Gateway AppGate Client 2 Control Channel Encrypted, Tunneled Data Channel PKI Identity Management Policy Model Graphical Admin Console 1

- 16. Summary 16 Utilizes an authenticate first approach Removes attacks including zero day, DDOS and lateral movement The Cloud Fabric can now be extended all the way to the user and device Leverages legacy applications by extending the SDP Architecture No longer need traditional network defense equipment (Firewall, VLAN, VPN, etc.) • Identity-centric security • Policies on user and cloud instances Identity-Centric Network Security
