THE POLICY ENGINE LANDSCAPE

Diamond Grid
CEDAR ⭐ COMMUNITY DIAMOND AWS, 2023
Language:Rust (core) + Go (k8s) + Java (bindings) Stars:1,466 (core) + 144 (k8s admission) License:Apache 2.0 Origin:Amazon — AWS Verified Access + Amazon Verified Permissions Lineage:Rust → formal verification → Cedar-spec (DRT tested)
KEY INSIGHT
Cedar is NOT OPA. PURPOSE-BUILT authorization language.
Designed for: “is principal P allowed to do action A on resource R?”
NOT for: general policy-as-code (that’s OPA/Rego)
ADELIC POUCH SCORE

Total: 57/70 = 81% ✓ COMMUNITY DIAMOND
OPA / REGO ⭐ COMMUNITY DIAMOND CNCF, 2016
Language:Go (engine) + Rego (policy DSL) Stars:10,000+ License:Apache 2.0 Origin:Styra → donated to CNCF 2021 Lineage:Datalog-inspired → general purpose → k8s admission (Gatekeeper) Conftest:v0.56.0 installed Day 97 on msi01
KEY INSIGHT
OPA is a GENERAL policy engine. Cedar is purpose-built auth.
OPA = “evaluate any policy against any JSON input”
conftest wraps OPA for file-based policy testing (k8s/TF/Docker)
TETRATE / ENVOY MESH ⚠ COMMUNITY WATCH
Language:Go Stars:701 (proxy-wasm-go-sdk) + 386 (func-e) Focus:Envoy proxy + Istio tooling + WASM extensions
KEY INSIGHT
Tetrate is the company behind Istio commercial support.
Their tools = the control plane for the ambient mesh we want.
tetrate-service-bridge-sandbox has AKS demo (HCL!)
KYVERNO ⭐ COMMUNITY DIAMOND CNCF incubating
Language:Go Origin:Nirmata → CNCF incubating Focus:Kubernetes-native policy (no Rego) Status:Already installed on eose-dev k3s
KEY INSIGHT
Kyverno policies = YAML (not Rego).
Easier to write than OPA/Gatekeeper for k8s-only use.
FALCO ⭐ COMMUNITY DIAMOND CNCF graduated
Language:C++ (engine) + Go (falco-exporter) Focus:Runtime threat detection (eBPF) Status:Installed on eose-dev k3s (modern_ebpf driver)
KEY INSIGHT
Falco = the ONLY runtime layer. OPA/Kyverno = admission.
Falco catches what slips through admission.
CONFTEST ⭐ COMMUNITY DIAMOND
Language:Go (wraps OPA) Stars:~2,800 Focus:Policy testing for files (k8s/TF/Dockerfile/etc.) Status:v0.56.0 + OPA 0.69.0 installed msi01 Day 97
KEY INSIGHT
conftest = OPA for CI/CD. Run before kubectl apply.
The PRE-DEPLOY gate. OPA/Gatekeeper = the POST-DEPLOY gate.
Both needed. conftest catches it before it hits the cluster.

VERDICT: NOT COMPETITORS. COMPLEMENTS.
Cedar = “can kayyo@pemos.ca call this API?” (identity auth)
OPA = “does this Deployment have memory limits?” (config policy)
Use both: Cedar for authz gates, OPA/conftest for config gates

The actuarial argument: fix the 68 no-limits containers = CA$144 cost = removes the WPA BREAK signal = prevents potential CA$7,000/mo AKS overrun from runaway pods. At CA$75/hr EOSE Labs rate (same as bounty testimony rate) — policy debt is cheap to fix, catastrophic to ignore.

COI — CERTIFICATE OF INSURANCE PATTERN

Policy Compliance COI
In traditional insurance: a COI proves coverage exists for a specific engagement.
In EOSE fleet: a Policy COI proves compliance exists for a specific deploy.

CEDAR FOR EOSE: INTEGRATION SPIKE

Cedar k8s Webhook
Current EOSE auth model:
OAuth2-proxy (Google) → email in allowlist → service access
This is L0 auth — email = identity. That’s it.
Principal: User {"email": "kayyo@pemos.ca", "role": "admin"} Action: Action {"name": "kubectl-apply", "namespace": "pemos-system"} Resource: Resource {"kind": "Deployment", "name": "mefine-static"} Context: {"gamma1_epoch": 97, "sostle_level": "L2"} // Cedar policy syntax: permit( principal in Role::"fleet-admin", action == Action::"kubectl-apply", resource in Namespace::"pemos-system" ) when { context.sostle_level >= 2 && context.gamma1_epoch == 97 };

This replaces email allowlists with structured Cedar policies. Every API call to the fleet = Cedar evaluation. Verdict = ADMIT/DENY. Logged. Indexed by PEMCLAU.

INTEGRATION PLAN
›
cedar-access-control-for-k8s webhook → replace/augment current oauth2-proxy
›
Cedar policies stored in git (policy/cedar/*.cedar)
›
conftest-eose validates Cedar policy files pre-deploy
›
Full audit trail: every authz decision = loom corpus entry
§ 08

TETRATE + AMBIENT MESH POLICY

Szabo V11 Vision
proxy-wasm-go-sdk 701⭐
›Write Envoy WASM filters in Go
›Custom auth/policy filters for waypoints (L7 ambient mesh)
›MECIPOL D-class checks as WASM filters = inline policy
func-e 386⭐
›Run Envoy easily for local testing
›Test WASM filters before deploying to waypoints
›The “conftest” of the ambient mesh layer
tetrate-service-bridge-sandbox
›AKS demo in HCL
›Starting point for Szabo V11 mesh setup
›Shows TSB (Tetrate Service Bridge) on AKS
AMBIENT MESH POLICY CHAIN (SZABO V11 VISION)
Request → ztunnel (L4, mTLS) → waypoint (L7, Envoy) ↓ WASM filter (Go, proxy-wasm-go-sdk) ↓ Cedar policy evaluation ← authz: who can do what? ↓ OPA/conftest policy check ← config: is this valid? ↓ MECIPOL verdict → ADMIT/DENY ↓ Response (or 403)
Every request through the mesh = evaluated against Cedar (authz) + OPA (config) + WASM (custom). The policy stack is in the data plane. No sidecar needed.
