What is a key requirement of remote access under CMMC practice AC.L2-3.1.12?

The requirement under CMMC practice AC.L2-3.1.12 emphasizes the importance of using encrypted methods for remote access, with the goal of ensuring confidentiality. This means that when employees or authorized users connect to the organization's network remotely, the data transmitted should be protected from unauthorized access and interception. Encrypted Virtual Private Networks (VPNs) are specifically designed to create a secure connection over the internet, providing a layer of encryption that helps safeguard sensitive information exchanged during remote sessions.

Using encrypted VPNs is essential for maintaining the integrity and security of data, especially given the increasing prevalence of cyber threats. This practice helps organizations comply with CMMC standards, which focus on safeguarding controlled unclassified information (CUI) and establishing robust security protocols for remote connectivity.

In contrast, options suggesting open access to all users, unmonitored sessions, or free access without restrictions lack the necessary security measures and would expose the organization to significant vulnerabilities, undermining the central objectives of CMMC compliance.
