Why is it critical to adapt security controls based on a system's purpose?

Adapting security controls based on a system's purpose is essential because it enhances their effectiveness in mitigating threats. Different systems serve various functions and are exposed to unique risks; therefore, one-size-fits-all security measures may not provide adequate protection. Tailoring security controls ensures that they are relevant to the specific threats associated with a system's operations, making them more capable of addressing vulnerabilities and risks effectively.

For example, a financial transaction system may need stricter access controls and logging mechanisms compared to an internal employee portal, where information sensitivity levels might differ. By aligning security measures with the system's intended purpose, organizations can better safeguard their assets and ensure compliance with relevant regulations and standards. This strategic approach to security allows for a more proactive stance in identifying and responding to potential threats, ultimately contributing to the overall security posture of the organization.
