Asset Inventory

An asset inventory is a comprehensive list of all hardware, software, data, and information assets within an organization, serving as the foundation for security management and compliance.

An asset inventory (also called asset register or CMDB) is a documented list of all assets that an organization owns, operates, or is responsible for. It's a foundational requirement for security and compliance programs.

Types of assets to inventory: - Hardware: Servers, laptops, mobile devices, network equipment - Software: Applications, operating systems, libraries - Data: Databases, file systems, cloud storage - Cloud Resources: VMs, containers, SaaS applications - People: User accounts, service accounts - Vendors: Third-party services and integrations

Key attributes to track: - Asset owner and custodian - Classification/criticality level - Location (physical or logical) - Network connectivity - End of life/support dates - Patch status

Asset inventory is required by virtually every compliance framework and enables: - Vulnerability management - Configuration management - Incident response - Disaster recovery planning

Why It Matters

You cannot protect what you do not know exists. Asset inventory is the foundation of every security program—without it, vulnerability management, patch management, and incident response all operate blindly. Auditors will ask for a complete asset inventory as one of their first evidence requests, and gaps in your inventory translate directly to gaps in your security posture.

Key Points

Foundation for all security and compliance programs

Must include hardware, software, data, and cloud assets

Each asset needs an owner and classification

Should be continuously updated, not annual snapshots

Enables vulnerability management and incident response

Applicable Compliance Frameworks

SOC 2 ISO 27001 HIPAA PCI DSS NIST CSF

Frequently Asked Questions

How often should asset inventory be updated?

Continuously is ideal through automated discovery. At minimum, quarterly reviews. Cloud environments especially need real-time tracking due to dynamic provisioning.

What is a CMDB?

Configuration Management Database (CMDB) is an asset inventory that also tracks relationships between assets. Common tools include ServiceNow, Snipe-IT, and cloud-native solutions.
