How are portable storage devices defined in the context of information systems?

In the context of information systems, portable storage devices are defined as devices that can be easily inserted and removed. This characteristic is crucial because it allows users to transport data across different systems and locations conveniently. These devices, such as USB flash drives, external hard drives, and SD cards, are designed for flexibility and ease of use, enabling quick access to stored data when plugged into compatible systems. This definition emphasizes their mobility and versatility in data management.

This fundamental understanding is important for CMMC assessors as it aligns with controls related to data protection and risk management, particularly in environments that handle sensitive information. Proper identification and handling of portable storage devices are vital for ensuring that data security measures are applied correctly. As mobile devices, they often present unique security challenges that need to be addressed through proper policies and procedures.
