What is a security baseline?

A security baseline comprises a defined set of minimum security controls and practices that an organization should implement to safeguard its information assets effectively. Establishing a baseline allows organizations to identify the minimum security requirements necessary to protect their systems and data against potential threats. This foundational reference serves as a guide for implementing security measures, measuring security posture, and ensuring compliance with applicable regulations and standards.

By determining a security baseline, organizations can create a framework that helps prioritize security efforts, allocate resources effectively, and minimize risks to acceptable levels. The baseline may vary based on the organization's size, industry, regulatory obligations, and the specific threats faced, but its core purpose remains consistent: to define the essential security measures needed to protect critical assets from vulnerabilities and attacks.

In contrast, the other options presented do not correctly define what a security baseline is. Financial benchmarks or reports on past incidents do not provide the necessary controls for maintaining security. Similarly, while regulatory requirements may influence an organization's security practices, they do not directly equate to the concept of a security baseline itself.
