An untrusted network typically implies a network without security protocols. In cybersecurity, the concept of trust is critical, especially in relation to data transmission and access control. An untrusted network lacks the necessary security measures, such as encryption, strong authentication protocols, and intrusion detection systems, making it vulnerable to various threats, including eavesdropping, data interception, and unauthorized access.

Networks categorized as untrusted are often open to the public or less secure environments, which may lead to increased risk for the data and systems connected to them. Therefore, users must exercise caution and implement additional security measures when accessing resources over an untrusted network.

In contrast, a private network with restricted access suggests a more controlled and secured environment, where only authorized users can gain access. Networks connected to secure government sites and networks only accessible to internal employees typically require established security protocols to protect sensitive information, which positions them as trusted rather than untrusted.
