Cyber Essentials — Rego Policies for OPA

6 open-source Rego policies encoding frameworks/regional/cyber_essentials policies. Apache 2.0, Rego v1, ready to load into OPA or Enterprise OPA.

What this is

6 Rego policy files encoding frameworks/regional/cyber_essentials policies, part of the Rego Policy Libraries — a standalone, dependency-free collection of Open Policy Agent policies for published security and compliance standards. No orchestrator, no agent, no vendor runtime.

Load and query it

git clone https://github.com/ynotbhatc/rego_policy_libraries.git
opa eval -d rego_policy_libraries/frameworks/regional/cyber_essentials -f pretty 'data'

Or load into a running OPA:

for f in rego_policy_libraries/frameworks/regional/cyber_essentials/*.rego; do
  curl -X PUT --data-binary @"$f" "$OPA/v1/policies/$(basename $f .rego)"
done

Two ways to use these policies

Gating a change of state — evaluate a proposed action before it proceeds, and refuse it if it violates the standard. Measuring state — evaluate collected facts about an environment against the standard to produce compliance evidence. The same policy content serves both; only the integration differs.
