Study Notes

SDP & Industry Adopted Solutions

Network Access Control: Ensures only authorized devices can access network resources.
Virtual Private Network (VPN): Provides secure remote access by encrypting data over the internet.
Identity & Access Management (IAM): Manages user identities and access privileges across systems.
SDP & Identity Lifecycle Management: Facilitates the creation, maintenance, and deletion of user identities within SDP frameworks.
SDP & Open Authentication Protocols: Supports secure user authentication using standardized protocols.
Next Generation Firewall: An advanced firewall technology that offers capabilities beyond traditional firewalls, such as application awareness and intrusion prevention.

Core Tenets, Underlying Technologies, & Architecture

SDP Core Tenets: Focuses on essential principles guiding the secure perimeter model.
Underlying Technology: Encompasses the technical foundations supporting SDP.
Drop-All Firewall: Implements a security posture that denies all traffic by default until explicitly allowed.
Separate Control & Data Planes: Enhances security by isolating control commands from data traffic.
Mutual Transport Layer Security (mTLS): Ensures both client and server authenticate each other during a secure connection.
Single Packet Authorization (SPA): A security protocol that allows unique user requests which cannot be replayed.

SPA Benefits and Limitations

Benefits of SPA: Provides service restriction with a default drop-all firewall to block unauthorized access and reconnaissance.
Limitations of SPA: Implementation complexities and potential challenges in ensuring all packets are properly handled.

SDP Architecture Components

Initiating Hosts: Devices that request access to services.
SDP Client: Software or application that connects to the SDP framework.
Accepting Hosts: Resources that grant access upon successful authentication.
Controller: Central management component that oversees authentication and authorization processes.
Gateway: Bridges communication between clients and servers within the SDP environment.

SDP Secure Workflow

Outlines the steps and checks involved in securely connecting users and devices through SDP.

Basics of SDP Deployment Models

Architectural Considerations: Elements to factor in when designing SDP deployments like existing network infrastructures and user experience.
Deployment Models: Various configurations for implementing SDP:
- Client-to-Gateway Model
- Client-to-Server Model
- Server-to-Server Model
- Client-to-Server-to-Client Model
- Client-to-Gateway-to-Client Model
- Gateway-to-Gateway Model

Onboarding and Device Validation

Onboarding Process: Involves initial setup of SDP controllers, gateways, and clients for secure access, requiring authentication for ongoing connections.
Device Validation: Ensures only devices with valid credentials access the network, utilizing certificates to establish trust.

mTLS in Various IT Environments

Particularly effective in environments with strict security needs and low operational complexity, such as B2B applications.

Conclusion

Emphasizes the importance of understanding and implementing SDP principles and technologies for robust security frameworks.
