12. An alert references attacks associated with a zero-day exploit. An analyst places a bastion host in the network to reduce the risk of the exploit. Which of the following types of controls is the analyst implementing?
Answer: A
The analyst is implementing a compensating control.
By placing a bastion host in the network, the analyst is providing an alternative measure to mitigate the risks associated with the zero-day exploit, which characterizes a compensating control.
A) Compensating
This option is correct as it describes a control that is used to provide an alternative solution to a security issue when the primary control is not feasible or effective. The implementation of the bastion host serves to enhance security by acting as a barrier, thereby compensating for potential vulnerabilities within the network.
B) Detective
This option is incorrect because detective controls are designed to identify and alert on security incidents after they have occurred. The creation of a bastion host does not detect attacks but rather aims to prevent them from occurring in the first place.
C) Operational
This option is not applicable since operational controls refer to processes and procedures put in place to manage security on an ongoing basis. While the bastion host is a part of operational security, it is specifically serving as a compensating control for the identified threat.
D) Physical
This option is incorrect as physical controls pertain to tangible barriers or protections, such as locks or security guards, that protect physical assets. The bastion host is a virtual solution, making it unrelated to physical controls.
Conclusion
In summary, the use of a bastion host effectively illustrates the implementation of a compensating control, as it provides an alternative method to address the risks introduced by the zero-day exploit. All other options fail to accurately describe the nature of the control being applied, emphasizing the importance of compensating measures in cybersecurity strategies.
