Enterprise Security Governance & Risk Assessment Framework

A structured Governance, Risk, and Compliance (GRC) case study simulating the design of an enterprise-wide security program for a global organization. The project integrates risk assessment, governance, incident response, and compliance aligned with industry frameworks.

Executive Summary

This project demonstrates the design of a complete enterprise security program where risk-driven analysis informs governance decisions, security controls, and resilience planning. It reflects real-world GRC operations across global environments with cloud, IoT, and regulatory considerations.

Project Overview

• Scope: End-to-end enterprise GRC program design
• Domains: Risk Management, Governance, Incident Response, Compliance
• Frameworks: ISO 27001, NIST CSF, CIS Controls, GDPR
• Risk Methods: Qualitative & Quantitative Analysis (CIA, SLE, ALE)

Key Deliverables

• Enterprise Case Study (Global Architecture Firm simulation)
• Threat Modeling (12+ attack scenarios)
• Risk Assessment (CIA-based qualitative + ALE/SLE quantification)
• Enterprise Information Security Policy (EISP)
• Incident Response Plan (IRP)
• Disaster Recovery Plan (DRP)
• Business Continuity Plan (BCP)
• Security Architecture Design
• Physical Security Controls
• Security Governance Structure (roles & responsibilities)

Methodology

The project follows a structured GRC lifecycle aligned with enterprise security practices:

1. Defined organizational context and critical assets
2. Identified threats and mapped attack vectors
3. Performed qualitative and quantitative risk assessments (CIA, ALE, SLE)
4. Developed security policies aligned with ISO 27001
5. Designed incident response, disaster recovery, and business continuity plans
6. Proposed security architecture and physical controls
7. Established governance structure with defined roles and accountability

Sample Findings

• High-risk threats: insider threats, unauthorized access, IoT exploitation
• Critical assets classified based on CIA impact (financial systems, data centers)
• Quantitative risk evaluation using Annual Loss Expectancy (ALE)
• Identified control gaps in phishing resistance, DDoS mitigation, and compliance readiness

Framework Alignment

• ISO 27001: Information Security Management System (ISMS) design principles
• NIST CSF: Identify, Protect, Detect, Respond, Recover lifecycle
• CIS Controls: Security control prioritization and baseline hardening
• GDPR: Data protection and privacy compliance considerations

Tools & Concepts

• Risk Assessment (Qualitative & Quantitative)
• CIA Triad (Confidentiality, Integrity, Availability)
• ALE / SLE Financial Risk Modeling
• Threat Modeling Techniques
• Security Policy Development
• Incident Response Lifecycle
• Business Continuity & Disaster Recovery Planning

Skills Demonstrated

• Governance, Risk & Compliance (GRC)
• Enterprise Risk Analysis
• Security Policy Design
• Incident Response Planning
• Business Continuity Management
• Security Architecture Design
• Regulatory & Compliance Alignment
