Risk acceptance of an exception to a security control would MOST likely be justified when:

The most likely justification for risk acceptance of an exception to a security control is when the business benefits exceed the loss exposure. Risk acceptance is a risk response strategy that involves acknowledging and tolerating the risk, without taking any action to reduce or transfer the risk. An exception to a security control is a deviation or non-compliance from the established security policy or standard, due to a valid business reason or circumstance. Risk acceptance of an exception to a security control may be justified when the business benefits exceed the loss exposure, which means that the value or advantage of the exception outweighs the potential cost or harm of the risk. For example, an exception to a security control may enable faster or easier access to the system or data, which may improve the productivity, efficiency, or satisfaction of the users or customers, and generate more revenue or profit for the business. The business benefits of the exception may exceed the loss exposure of the risk, which may be low or negligible, or may be mitigated by other controls or factors. Therefore, risk acceptance of an exception to a security control may be a reasonable and rational decision, based on the cost-benefit analysis of the exception and the risk. Automation cannot be applied to the control, the end-user license agreement has expired, and the control is difficult to enforce in practice are not the most likely justifications for risk acceptance of an exception to a security control, as they are either irrelevant or insufficient reasons, and they do not consider the business benefits or the loss exposure of the exception and the risk. References = CRISC Review Manual, 6th Edition, ISACA, 2015, page 50.
