Security — Conceptual Overview
Audience: Implementers, Architects, Security Engineers Governance Rule: DGP-30
1. What Security Refers To
Security in MPLP refers to the cross-cutting protection dimension that spans across all protocol layers. It concerns the trust boundaries, access controls, and audit mechanisms that implementations may provide.
Security is not a standalone security framework. It is a conceptual area where protocol-level considerations intersect with implementation-level security controls.
2. Conceptual Areas Covered by Security
Security concerns the following areas:
| Conceptual Area | Description |
|---|---|
| Role-Based Access | Relates to capabilities defined in Role module (plan.create, confirm.approve) |
| Approval Workflows | Concerns human-in-the-loop patterns in Confirm module |
| Audit Trails | Is involved in Trace record semantics |
| Source Identification | Relates to L4 integration event source requirements |
| State Scoping | Concerns Context-based isolation boundaries |
3. What Security Does NOT Do
Security explicitly does not:
- ❌ Define cryptographic algorithms
- ❌ Mandate specific authentication protocols (OAuth, SAML, etc.)
- ❌ Prescribe network security measures (TLS, firewalls)
- ❌ Define data classification levels
- ❌ Constitute a security framework or compliance standard
4. Where Normative Semantics Are Defined
The normative semantics related to security are NOT defined on this page.
They are distributed across:
| Normative Source | What It Covers |
|---|---|
Role Module (mplp-role.schema.json) | Capabilities array, role_id bindings |
Confirm Module (mplp-confirm.schema.json) | Approval workflows, override mechanisms |
Trace Module (mplp-trace.schema.json) | Audit record structure |
| L4 Integration Invariants | Source identification requirements |
| L3 Architecture Deep Dive | AEL sandboxing, VSL encryption considerations |
5. Conceptual Relationships
Security interacts with the following protocol elements:
6. Reading Path
To understand security-related normative semantics, read:
- Role Module — Capability definitions
- Confirm Module — Approval workflows
- Trace Module — Audit records
- L3 Architecture Deep Dive — Sandboxing, encryption
