Repository: agentic-incident-response-assistant
Brand: CyberDudeBivash Sentinel APEX Ecosystem
Domain: Agentic AI Systems & Automated Incident Response Scaffolding
Core Features: Planner/Validator Multi-Agent Architecture, Read-Only Permission Gates, Step Cutoff Limits, and Immutable Episodic Audit Trails
1. Executive Summary & Architecture Overview
The agentic-incident-response-assistant is a production-grade, safety-constrained Agentic AI framework built for the CyberDudeBivash platform
This repository demonstrates Safe Agentic Autonomy by enforcing a strict separation of concerns through a Planner/Validator Architecture
Planner Agent: Interprets incoming SOC telemetry and decomposes complex goals into step-by-step action proposals
. Validator Agent: Acts as an independent policy checkpoint, verifying every proposed tool invocation against strict allowlists and permission scopes before execution
. Read-Only Permission Gates: Ensures that investigative tools (log parsing, metric checks) run automatically, while any high-impact write/action tool (host isolation, firewall rule changes) requires explicit Human-in-the-Loop (HITL) authorization
. Step Cutoff Limits: Prevents runaway execution loops by enforcing hard programmatic iteration bounds
. Episodic Audit Trails: Logs every observation, reasoning step, tool parameter, and human decision into an immutable JSON trail for post-incident audits and forensic analysis

# Agentic Incident Response Assistant (`06-agentic-incident-response-assistant`)
**CyberDudeBivash Sentinel APEX Ecosystem**
*Enterprise-Grade Constrained Agentic AI Framework for Automated SOC Incident Triage*
---
## Overview
The `agentic-incident-response-assistant` provides a safety-first, governed Agentic AI scaffolding for Security Operations Centers (SOCs)[cite: 1]. It transitions incident response from manual triage to **Controlled Agentic Autonomy**[cite: 1].
### Key Safeguards
* **Planner/Validator Architecture:** Isolates task step formulation from policy and security validation[cite: 1].
* **Permission Gates:** Read-only investigative tools auto-run; restricted write tools (host isolation, service restarts) enforce mandatory Human-in-the-Loop (HITL) authorization gates[cite: 1].
* **Step Cutoff Limits:** Programmatic boundaries prevent infinite loops and runaway API compute costs[cite: 1].
* **Immutable Audit Trail:** Logs every observation, reasoning step, tool call, and analyst approval into episodic JSON audit files[cite: 1].

Integration with Sentinel APEX Threat Intelligence Platform
This repository integrates directly into the CyberDudeBivash Sentinel APEX Platform:
SIEM / EDR Trigger: Ingests alerts via Webhook into
core/orchestrator.py.Automated Triage: Runs read-only log parsing and network telemetry gathering automatically.
Analyst Dashboard Gate: Pushes restricted mitigation proposals directly to SOC Analyst Slack/Teams channels or SIEM dashboards for one-click HITL approval.
Compliance Audit Sync: Ships episodic audit JSONs directly to SIEM cold storage for ISO27001/SOC2 compliance audits[cite: 1].
Commercial Licensing
Under the CyberDudeBivash Pvt. Ltd. ecosystem, this repository forms a core building block for:
SaaS B2B Incident Response Modules: Sold as a pre-packaged agentic integration for enterprise SIEMs (Splunk, Microsoft Sentinel, Elastic).
Cybersecurity Advisory Services: Deployed during incident response retainer engagements to accelerate threat triage and forensic timeline reconstruction.
