The System and Communications Protection (SC) Policy and supporting documents are a critical aspect of the CMMC framework. The SC domain involves safeguarding the integrity and confidentiality of data in transit and at rest and protecting networks and information systems from unauthorized access and disclosure. This collection of documents focuses on the implementation of security measures to protect information systems and the communications transmitted or received by these systems. These documents aim to ensure that organizations have robust protections in place for their information systems and the communications that occur on these systems and include requirements for remote access, gateway security, network access, collaborative computing, remote control, and VOIP.
