Draft v0.1.06 frameworks · 29 control themes

Which control answers which control.

Look up a SOC 2, PCI DSS, ISO 27001, NIST CSF, HIPAA or NIST 800-53 requirement and see what it lines up with in the other five, with the evidence an auditor usually asks for.

Control objectiveSOC 2PCI DSS 4.0
Asset and system inventory
CC6.1Logical access security (inventory of information assets is a point of focus)
12.5.1Inventory of system components in scope for PCI DSS is maintained
12.5.2PCI DSS scope is documented and confirmed at least every 12 months
Authentication, unique IDs and multi-factor authentication
CC6.1Logical access security software, infrastructure and architectures
8.2User identification and related accounts are strictly managed
8.3Strong authentication for users and administrators is established and managed
8.4Multi-factor authentication is implemented
8.5MFA systems are configured to prevent misuse
Encryption at rest and key management
CC6.1Logical access security (encryption of data at rest)
3.5Primary account number is secured wherever it is stored
3.6Cryptographic keys used to protect stored account data are secured
3.7Key management processes and procedures are defined and implemented

Each number is how many shared control themes connect the two frameworks. Darker cells overlap more.

Control objectives

The common ground. Each square is a framework that covers the objective.

For AI agents

The same data is an API that agents pay for per call, with no signup or key. Payment is USDC over the x402 protocol, from $0.01 a call. llms.txt and openapi.json describe it.
