What does CMMC requirement AC.L2-3.1.13 mandate for OSCs regarding remote access sessions?

The correct response is that CMMC requirement AC.L2-3.1.13 mandates the use of FIPS-validated cryptography for organizations seeking compliance. This requirement ensures that any remote access sessions are secured using cryptographic methods that have been validated to meet specific federal security standards established by the Federal Information Processing Standards (FIPS).

FIPS-validated cryptography is crucial for protecting sensitive information transmitted over potentially insecure communication channels, especially in a remote access context. By adhering to these standards, organizations can safeguard the integrity and confidentiality of their data while ensuring compliance with federal regulations.

While the other choices may touch on important aspects of security, they do not align with the specific focus of AC.L2-3.1.13. Regular password updates, two-factor authentication, and monthly security audits are significant controls for enhancing security but are not the particular requirements set forth by this specific CMMC criterion. This highlights the importance of understanding the nuances and specific mandates of the CMMC framework to achieve compliance effectively.
