NIST SP 800-171 & CMMC 2.0 3.7.5 Requirement:
Require multifactor authentication to establish nonlocal maintenance sessions via external network connections and terminate such connections when nonlocal maintenance is complete.
NIST SP 800-171 & CMMC 2.0 3.7.5 Requirement Explanation:
When a person remotely connects to a system to perform maintenance they generally do so with a privileged account. This creates additional risk that can be reduced by requiring multifactor authentication.
Example NIST SP 800-171 & CMMC 2.0 3.7.5 Implementation:
When system administrators connect to your network via a remote VPN connection with their privileged accounts require them to authenticate using multifactor authentication.
NIST SP 800-171 & CMMC 2.0 3.7.5 Scenario(s):
- Scenario 1:
Alice a system administrator needs to connect to her company's file server from home using a VPN connection. Because she is an admin her account is configured to require multifactor authentication when she connects to the VPN.
