Assets, Threats, and Vulnerabilities in a Security Assessment

In any comprehensive security assessment, understanding and documenting assets, threats, and vulnerabilities is essential for identifying and managing risks. Here’s a structured approach to represent and analyze these elements.

Assets

Assets are the valuable resources that need protection in an organization, ranging from sensitive data and intellectual property to physical devices and even personnel. To effectively show assets, you should start by maintaining an asset inventory — a comprehensive list that categorizes assets by type (hardware, software, data, or people) and details each asset’s owner, importance, and sensitivity level.
