Zero Trust Engineering — North-south ingress and egress security

/02 About

Networks and environments engineering reference for north-south ingress and egress security, including policy, logical interfaces, recovery and assurance.

Purpose: North-south ingress and egress security. Domain: Networks and environments. Family: decision. Scenario trigger: Inspect inbound request or outbound data transfer. Input assurance: Traffic direction, authenticated request context and destination trust. Evaluation: Assess ingress exposure and egress authorization policy. Governing policy: Ingress and egress application-aware filtering policy. Resource-side obligation: Mediate permitted requests and sanctioned outbound destinations. Protected concern: Enterprise edge security gateway. Logical interface: Ingress identity egress destination application context verdict and evidence. Evidence: Ingress request attributes egress destination and action evidence. Failure: Unexpected external destination or bypass of enforced edge. Required recovery: Block transfer and identify compromised workload or route. Architectural invariant: Outbound traffic requires policy independent of internal source location Adoption: replace reference roles with concrete owner-controlled services. Specify exact provider/consumer identities, schema fields and classifications, signal provenance and freshness, idempotency, authorization lifetime, timeout/retry limits, observation and tamper evidence. A denied or failed operation must not silently become a permitted one. Scope: original vendor-neutral, implementation-agnostic technical reference model. Illustrative logical components and behaviors are neither a deployed system nor evidence of regulatory compliance. Package identities remain stable within the package; cross-package semantic reconciliation requires separate explicit registry support.
