Study Notes
SDP Principles
- SDP architecture emphasizes least privilege and segregation of duties.
- Key controls include dynamic rules on drop-all firewalls to enhance security.
- Servers and services are hidden to prevent unauthorized access.
- Authentication is required before establishing connections, ensuring users are authorized on specific devices.
- Single packet authorization (SPA) and mutual transport layer security (mTLS) provide secure communication.
- Access control is fine-grained, allowing for detailed device validation.
Relationship Between SDP & ZT
- Zero Trust (ZT) is the overarching model encompassing SDP.
- ZT principle: No assumptions about trustworthiness are made when entities request resource access.
- ZT starts with no pre-established privileges, allowing privileges to be added constructively.
- ZT operates under the assumption of breach, necessitating verification of access requests for all resources.
- ZT emphasizes creating micro-perimeters around sensitive data to enhance control and visibility.
- Access requests require verification before granting permission, with continuous monitoring throughout the session.
- While SDP has different origins than ZT, both share the principle of prioritizing verification over trust.
- SDP requires users to sign in cryptographically for access to hidden assets in public infrastructures.
- SDP integrates various security controls (applications, firewalls, clients) for a unified security approach.
History of SDP
- SDP originated from the U.S. Defense Information Systems Agency's initiative in 2007 focused on cybersecurity.
- The CSA established the SDP framework in 2013, which aims to control access based on identity and device attestation.
- SDP operates using a need-to-know model, verifying device posture and identity before allowing access.
- Resources in an SDP environment are hidden without DNS information or IP addresses, making them undetectable without specific access permissions.
- As organizations pursue digital transformation, SDP addresses evolving cybersecurity threats and challenges.
