Knowing What You Need to Protect

In security, you cannot protect what you don't know you have. Asset Inventory is the process of creating a complete and accurate list of all hardware, software, and data within an organization.

Types of Assets

1. Hardware: Servers, workstations, network devices, mobile devices.
2. Software: Operating systems, applications, custom code.
3. Data: Customer lists, intellectual property, financial records (often the most valuable asset).

Importance for Security

• Scope Definition: Ensures penetration testers know the boundaries.
• Patching: You can't patch a server you don't know exists (Shadow IT).
• Risk Assessment: Allows the security team to categorize assets by criticality. A critical database requires more security controls than a standard desktop PC.

Tool Note: Automated asset discovery tools are used in large environments to scan the network and identify unauthorized devices (rogue devices).
