Implementation Tiers Detail

Tier 1: Partial

• Risk Management Process: Ad hoc; not formalized
• Integrated Risk Management: Limited awareness; irregular risk practices
• External Participation: No formal collaboration with external entities
• Governance: Cybersecurity not integrated into enterprise risk management

Tier 2: Risk-Informed

• Risk Management Process: Approved by management but may not be policy
• Integrated Risk Management: Awareness at organizational level; some sharing
• External Participation: Aware of ecosystem role; limited collaboration
• Governance: Some integration of cybersecurity into enterprise risk

Tier 3: Repeatable

• Risk Management Process: Formally approved policies; regularly updated
• Integrated Risk Management: Organization-wide approach; consistent implementation
• External Participation: Regular collaboration with partners and ecosystem
• Governance: Cybersecurity fully integrated into enterprise risk management

Tier 4: Adaptive

• Risk Management Process: Continuous improvement using advanced techniques
• Integrated Risk Management: Real-time shared awareness; dynamic risk response
• External Participation: Active leadership in ecosystem risk management
• Governance: Agile cybersecurity governance adapting to changes
