Security Program Maturity

Maturity models, capability assessment, roadmap development, and continuous improvement.

Overview

Maturity models measure and improve security capabilities.

Maturity Levels

Level 1: Initial
- Ad-hoc processes
- Reactive

Level 2: Managed
- Documented processes
- Repeatable

Level 3: Defined
- Standardized processes
- Organization-wide

Level 4: Quantitatively Managed
- Metrics-driven
- Measured

Level 5: Optimizing
- Continuous improvement
- Innovation

Capability Assessment

Maturity Model Framework

def assess_maturity(capability):
    levels = {
        1: "Initial - Ad-hoc",
        2: "Managed - Documented",
        3: "Defined - Standardized",
        4: "Measured - Metrics-driven",
        5: "Optimizing - Continuous improvement"
    }
    
    score = evaluate_capability(capability)
    return {
        "capability": capability,
        "level": score,
        "description": levels[score]
    }

Roadmap Development

# Security Maturity Roadmap

## Year 1: Foundation
- Document processes
- Implement basic controls
- Establish metrics

## Year 2: Enhancement
- Automate processes
- Advanced monitoring
- Compliance certification

## Year 3: Optimization
- Continuous improvement
- Threat intelligence
- Zero trust implementation

Continuous Improvement

Plan -> Do -> Check -> Act
  |     |     |      |
  |     |     |      +-- Improve
  |     |     +-- Verify
  |     +-- Implement
  +-- Design

Practice

Conduct a maturity assessment and develop a 3-year roadmap.
