Which function focuses on implementing controls for mission critical infrastructure services?

The function that focuses on implementing controls for mission-critical infrastructure services is "Protect." This function is essential in cybersecurity and risk management frameworks, such as the NIST Cybersecurity Framework. Protecting mission-critical infrastructure involves putting in place measures and controls that safeguard systems, data, and assets from potential threats and vulnerabilities. This includes security policies, training, access controls, and protective technologies that ensure the integrity and availability of critical services.

By concentrating on the Protect function, organizations aim to maintain the security and resilience of their operations, ensuring that essential services remain operational even in the face of adversities. This proactive approach is fundamental to risk management, especially in sectors where downtime can have severe consequences, such as energy, finance, and healthcare.

The other functions—Detect, Identify, and Respond—play important roles as well but focus on different aspects of risk management. Detect involves identifying potential security incidents, Identify focuses on understanding and managing cybersecurity risks, while Respond pertains to taking action during and after an incident has occurred. However, Protect is specifically focused on preventive measures and controls necessary to uphold mission-critical infrastructure.
