A.5.9 "Inventory of Information and Other Associated Assets," an information security auditor would review how an organization manages and maintains an inventory of its information assets and associated resources. Here's a breakdown of the evidence and areas an auditor might focus on:
-
Documentation and Policies:
-
Verify the existence of documented policies, procedures, or guidelines that define how information assets and associated resources should be inventoried.
-
Asset Identification:
-
Review the organization's process for identifying and categorizing information assets, including data, systems, devices, and facilities.
-
Asset Ownership:
-
Assess if each information asset has an identified owner responsible for its maintenance, protection, and security.
-
Classification and Labeling:
-
Evaluate whether assets are appropriately classified based on their sensitivity and criticality, and if they are labeled accordingly.
-
Asset Inventory Database:
-
Examine if the organization maintains a centralized database or system that tracks and manages the inventory of information assets.
-
Asset Attributes:
-
Review if the inventory includes relevant attributes for each asset, such as asset type, location, owner, classification, and associated risks.
-
Updates and Changes:
-
Assess how the organization manages updates, changes, and additions to the asset inventory as new assets are acquired or existing assets are retired.
-
Access Control and Authorization:
-
Evaluate if access to the asset inventory database is restricted to authorized personnel and if proper authentication and authorization mechanisms are in place.
-
Regular Review and Validation:
-
Verify if the asset inventory is regularly reviewed and validated to ensure its accuracy and completeness.
-
Integration with Other Processes:
-
Assess how the asset inventory process is integrated with other information security and IT management processes, such as risk management and change management.
-
Auditing and Monitoring:
-
Examine whether audit trails or logs are maintained to track changes to the asset inventory and who made those changes.
-
Disposal of Assets:
-
Review how the organization removes assets from the inventory when they are no longer in use or have reached their end of life.
-
Responsibilities and Accountability:
-
Evaluate whether roles and responsibilities for managing the asset inventory are clearly defined and understood by relevant personnel.
-
Asset Lifecycle Management:
-
Assess if the organization manages the entire lifecycle of each asset, from acquisition to disposal, and considers information security at each stage.
-
Training and Awareness:
-
Verify if personnel involved in managing the asset inventory receive appropriate training and awareness regarding asset management practices.
-
Incident Response and Recovery:
-
Evaluate if the asset inventory supports incident response and recovery efforts, enabling quick identification of affected assets.
By reviewing these areas, an auditor can determine whether the organization has established effective processes for identifying, classifying, managing, and protecting its information assets and associated resources in line with information security best practices.
