Asset Management
Definition
Asset management is the set of processes used to identify, record, control, and maintain an accurate inventory of information assets and the systems, services, and devices that store, process, or transmit them throughout their lifecycle. In an ISO/IEC 27001 context, effective asset management ensures you know what you have, who is responsible for it, how it is used, and what protections are required based on business criticality and information security needs. This commonly includes establishing an inventory with unique identifiers, assigning asset owners, defining acceptable use, and ensuring assets are returned or securely disposed of when no longer needed (e.g., Annex A controls such as 5.9 Inventory of information and other associated assets, 5.10 Acceptable use of information and other associated assets, and 5.11 Return of assets). Strong asset management supports risk assessment, incident response, access control, vulnerability management, and audit readiness by reducing blind spots like unmanaged endpoints, unknown cloud resources, or untracked SaaS accounts. Equivalent concepts appear across frameworks (e.g., the NIST Cybersecurity Framework's asset management outcomes, NIST SP 800-53 inventory-related controls, and CIS Controls for inventory and control of enterprise assets).
Real-World Examples
Startup asset inventory and ownership
A small company maintains a quarterly-updated asset inventory listing laptops, admin accounts, critical SaaS tools, and data stores, with an owner and classification for each item.
Scaleup discovery and device management
A growing team uses automated discovery plus endpoint management to reconcile devices, detect unmanaged machines, and trigger remediation when a device falls out of compliance.
Enterprise lifecycle and secure disposal
An enterprise ties procurement, tagging, CMDB records, license allocation, and decommission workflows together, requiring secure wipe evidence before assets are retired or transferred.
It is the practice of identifying and controlling information assets and related technology so ownership, usage, and required protections are clear across the full lifecycle.
You cannot protect or audit what you cannot see; accurate asset records reduce blind spots, support risk management, and provide evidence for security and compliance reviews.
ITAM covers hardware, virtual, and service assets end-to-end, while SAM focuses specifically on software entitlements, deployments, usage, and license compliance obligations.
An asset inventory tracks what exists and who owns it; a CMDB additionally models configuration items and their relationships to services, dependencies, and change processes.
Define scope and required fields, assign owners, capture assets from procurement and discovery sources, and reconcile regularly so additions, changes, and retirements are reflected.
Common fields include unique ID, asset type, owner/custodian, business function, location, environment, criticality, data classification, lifecycle status, and key security controls.
Review frequency depends on risk, but many organizations reconcile continuously via discovery and perform formal reviews at least quarterly and after major changes or incidents.
By comparing approved inventories to discovery and access logs, you can quickly detect unknown devices or services, assess exposure, and either onboard, restrict, or remove them.
It includes request/procurement, tagging and registration, secure configuration, monitoring and maintenance, transfers/returns, and verified secure disposal with records and approvals.
Common tools include discovery scanners, endpoint management/MDM, CMDBs, and license tracking; choose based on coverage, integration, data accuracy, reporting, and audit needs.
