Which of the following is an outcome of using ACAS?

The selection of enhanced security oversight as the outcome of using the Assured Compliance Assessment Solution (ACAS) is indeed the most appropriate choice. ACAS aims to continuously monitor and assess the security posture of information systems and networks. By implementing this solution, organizations benefit from improved visibility into their security environments, facilitating better decision-making regarding security measures and compliance with established standards.

With ACAS, security teams can receive real-time data on vulnerabilities, threats, and overall compliance status. This leads to a proactive approach in identifying and mitigating potential risks to the organization’s information systems. Enhanced security oversight ensures that any anomalies or deviations from compliance are quickly addressed, thereby strengthening the organization's defense mechanisms against cyber threats.

The other options, such as increased IT costs, reduced network speed, and mandatory third-party consulting, do not accurately reflect the primary outcomes one would expect from using ACAS. While there may be operational costs involved in implementing such systems, the overall goal is to create a more secure environment rather than increasing expenses or degrading performance. Therefore, the positive impact of enhanced security oversight stands out as the primary benefit of utilizing ACAS.
