Security Controls Baseline
Baseline security controls are the fundamental, minimum security measures an organization implements to protect its information systems and data, ensuring confidentiality, integrity, and availability. They serve as a starting point for a robust security posture, providing a foundation upon which more specialized controls can be built.
Definition:
The set of minimum security controls defined for a low-impact, moderate-impact, or high-impact information system.

What are Baseline Security Controls?
- Minimum Security: They represent the essential security practices that every organization should have in place, regardless of size or industry.
- Foundation for Security: Baseline controls act as a starting point for a comprehensive security program, providing a basic level of protection against common threats.
- Consistency and Auditability: They help ensure consistency in security configurations across an organization, making it easier to audit and manage security risks.
- Risk Reduction: Implementing baseline controls helps reduce the risk of cyberattacks, data breaches, and unauthorized access.
- Examples:
Common baseline controls include strong passwords, multi-factor authentication, firewalls, anti-malware software, regular software updates, and data backup and recovery procedures.
Why are Baseline Security Controls Important?
