What is a Cybersecurity RMF ISSO?

A Cybersecurity RMF ISSO (Risk Management Framework Information System Security Officer) is a professional responsible for ensuring the security and compliance of information systems within an organization, following the guidelines of the Risk Management Framework (RMF). The ISSO plays a key role in assessing, implementing, and maintaining security controls, ensuring that systems meet federal or organizational cybersecurity standards. They collaborate with system owners and other stakeholders to manage risks, document security processes, and support continuous monitoring. RMF ISSOs are particularly common in government and defense sectors, where strict security compliance is required.
