8. ICT Asset Classification, Security & Resilience
The Digital Operational Resilience Act (DORA) emphasizes the need for financial entities to classify, secure, and build resilience for their ICT assets (including applications and infrastructure). DORA requires a comprehensive inventory of ICT assets, classification by criticality, and robust security measures to mitigate risks. This guide provides a detailed overview of DORA compliance requirements related to ICT asset management at the asset level.

1. Regulatory Foundation
Regulatory Foundation
DORA Regulation (EU 2022/2554): Articles 5, 6, 8, 11, 13, and 15
RTS 2024/1774, Articles 4-5: ICT asset management specifics
RTS 2024/1774, Articles 11-12: Data and system security requirements
The classification and management of ICT assets are foundational elements of operational resilience under DORA. Financial entities must:
  • Identify and classify all ICT assets based on criticality to business operations
  • Implement security measures proportional to the asset's importance and risk level
  • Build resilience by ensuring assets can recover or continue functioning during disruptions
2. Asset Management Framework
2.1 Asset Inventory Requirements
Per RTS 2024/1774 Article 4, financial entities must maintain a comprehensive inventory including:
1
Unique asset identification
2
Location information (physical and logical)
3
Asset classification level
4
Owner identification and responsibilities
5
Business function mapping
6
Recovery time and point objectives
7
Network exposure status
8
Interdependency mapping
9
Support status and lifecycle tracking
The inventory must cover:
1
Applications (e.g., core banking systems, customer-facing platforms)
2
Infrastructure (e.g., servers, networks, cloud services, on-premises data centers)
3
Supporting tools (e.g., monitoring, backup, and recovery tools)
2.2 Critical Asset Requirements
Per RTS 2024/1774 Article 5, entities must implement:
3. Security Controls Framework
3.1 System Security
Per RTS 2024/1774 Article 11, implement:
  • Access restrictions and privilege management
  • Secure configuration baselines
  • Software authorization controls
  • Advanced malware protection
  • Data storage controls
  • Comprehensive endpoint security
Security controls must be proportionate to the asset's classification:
  • Critical Assets:
  • Advanced security measures (MFA, encryption, real-time monitoring, redundancy)
  • Important Assets:
  • Robust controls (RBAC, regular patching, vulnerability scanning)
  • Non-Critical Assets:
  • Standard security measures for basic protection
3.2 Data Protection
Per RTS 2024/1774 Article 12, ensure:
  • Data classification implementation
  • Protection measures aligned with sensitivity
  • Complete lifecycle management
  • Encryption at rest and in transit
  • Data masking or pseudonymization techniques
(See Data Security Guide for detailed requirements)
3.3 Identity and Access Management (IAM)
  • Enforce least privilege and role-based access control (RBAC)
  • Use MFA for critical applications and infrastructure
(See Security Operations Guide for details)
3.4 Asset Resilience
  • Redundancy and High Availability:
  • Implement failover mechanisms for critical assets
  • Use load balancing and clustering for essential functions
  • Backup and Recovery:
  • Regular backups stored in diverse locations
  • Automated testing of backup integrity
  • Restoration procedure validation
3.5 Continuous Monitoring
  • Deploy real-time monitoring tools
  • Implement SIEM systems for threat detection
  • Regular vulnerability scanning and penetration testing
4. Implementation Requirements
4.1 Asset Management Policy
Develop and maintain:
  • Comprehensive policy documentation
  • Regular review procedures
  • Update processes
  • Integration with ICT risk framework
4.2 Security Implementation
Establish:
  • Control mapping to asset criticality levels
  • Continuous monitoring requirements
  • Regular testing and validation
5. Integration Points
5.1 Risk Management
  • Integrate asset management with risk assessment
  • Monitor control effectiveness
5.2 Third-Party Management
  • Track provider assets and dependencies
  • Enforce security requirements
  • Include third-party services in asset inventory
  • Enforce SLAs for security and resilience
5.3 Incident Management
  • Define asset-related incident procedures
  • Establish response protocols
  • Ensure rapid identification and mitigation
5.4 Business Continuity
  • Define recovery priorities
  • Implement resilience requirements
  • Integrate with disaster recovery planning
5.5 Testing Requirements
  • Conduct regular asset security testing
  • Validate resilience measures
  • Perform penetration testing
  • Run disaster recovery simulations
  • Execute incident response drills
5.6 Threat Management
  • Implement asset threat monitoring
  • Maintain vulnerability management
6. Common Challenges and Solutions
6.1 Asset Discovery
Challenge: Maintaining complete asset inventory
Solution:
  • Deploy automated discovery tools
  • Conduct regular inventory reviews
  • Establish clear ownership assignment
  • Implement automated dependency mapping
6.2 Classification Consistency
Challenge: Ensuring accurate classification
Solution:
  • Define clear classification criteria
  • Conduct regular reviews

  • Align with data classification framework
6.3 Control Implementation
Challenge: Implementing appropriate security controls
Solution:
  • Apply risk-based approach
  • Conduct regular validation
  • Monitor control effectiveness
  • Ensure proportional security measures
6.4 Legacy Systems
Challenge: Older systems lacking modern security features
Solution:
  • Prioritize upgrades
  • Implement compensating controls
  • Plan system phase-out where appropriate
7. Key Success Factors
