Develop a defensive architecture study for the proposed Detection.Space security-operations platform. Cover Threat Hunter, Intel Synthesizer, Sigma Architect, Validator, Responder, Archivist, and Stage Monitor. Define the explicitly authorized test environment, assets, telemetry, threat model, identities, and human owners before discussing orchestration, Splunk integration, Sigma-to-SPL translation, response, observability, rollback, and audit. Cite NIST, MITRE ATT&CK, Sigma, Splunk, or other standards only where directly applicable and name the version. Treat autonomy and performance targets as unproven design claims until tested. Evaluate coverage, precision, recall, false positives, latency, drift, adversarial robustness, approval boundaries, containment, and recovery. Keep examples synthetic and defensive; provide no intrusion, evasion, credential theft, persistence, or destructive instructions. High-impact or novel actions require explicit human approval and reversible playbooks.
Deliver the system trust-boundary architecture, one contract per agent, the control and approval flow, an authorized validation plan with acceptance criteria, and failure-handling runbooks covering stop, rollback, escalation, evidence preservation, and audit review. Clearly separate proposed controls from implemented and independently tested controls.
