OSINT Agent Pattern Architecture

A reference implementation pattern for distributed OSINT (Open Source Intelligence) agents within the SFAMDF framework.

Overview

This pattern demonstrates how to implement a distributed OSINT collection and analysis system using SFAMDF principles:

Federated Orchestration - Raft-based consensus for high availability
Secure Execution - AgentBox sandboxing with policy enforcement
Human Oversight - Confidence-based escalation to expert analysts
Resilience - Distributed state with automatic failover

4. Security Threat Mitigations

Threat	Mitigation
Poisoned Source Data	Multi-source corroboration
Collection Fingerprinting	Randomized patterns + proxy rotation
Intel Exfiltration	Volume anomaly circuit breaker
HITL Manipulation	MFA + dual approval requirements
Orchestrator Compromise	Quorum + task signature validation

5. Resilience Patterns

Orchestrator Failure:

Raft consensus elects new leader in < 1 second
In-flight tasks redistributed to healthy nodes

Operator Failure:

Checkpoint-based recovery from distributed state
Task reassigned to healthy instance in same domain

Expert Unavailability:

Timeout-based escalation chain
Fallback to higher-authority expert pool

Network Partition:

Majority partition continues operation
Minority partition enters read-only mode
