Enabling a feature that inspects and validates IP address assignments across the network ensures that only authorized servers can issue network configurations. It can block illegitimate attempts to distribute network settings, thereby mitigating the risk associated with unauthorized entities disrupting network communication. Simply disabling ports does not resolve the issue of an illegitimate entity actively operating within the network. Enhancing the encryption of data transmission is important for data protection but does not address the core issue of protecting against unauthorized network configurations. Adjusting the level of security on peripheral defenses, such as a firewall, may enhance the network's overall security posture, but it will not directly prevent an internal entity from distributing potentially harmful network configurations.
