Which of the following is considered a technological control?

The correct answer is firewall software because it is a fundamental component of cybersecurity that uses rules to allow or block data traffic based on established security policies. Firewalls act as a barrier between trusted internal networks and untrusted external networks, protecting sensitive information from unauthorized access and potential cyber threats.

Technological controls like firewall software are essential in managing and mitigating risks in a cloud environment, providing a means to enforce security policies effectively. These controls can be automated, monitored, and updated to adapt to new security threats, making them an integral part of a comprehensive security strategy.

In contrast, the other options represent non-technological or administrative controls. For instance, firing personnel involves human resource decisions that do not directly utilize technology for security purposes. Similarly, a fireproof safe and a fire extinguisher are physical controls designed to protect data and assets from physical threats, such as fire, rather than addressing cybersecurity concerns. This distinction underscores the critical role of technological controls like firewall software in maintaining cloud security.
