Device Security Mode and Transport Types
Gain insights into the various device security modes and transport types in CUCM and discover how to secure your communication manager trunk effectively. When setting up a SIP trunk in Cisco Unified Communications Manager (CUCM), it is crucial to understand the different options available for device security mode and transport types. By selecting the appropriate settings, you can ensure that your communication channels are protected and encrypted.
The device security mode determines the level of security applied to your trunk. CUCM offers three options: non-secure, authenticated, and encrypted. Non-secure mode does not apply any security measures, while authenticated mode requires authentication between the devices. Encrypted mode, on the other hand, encrypts the entire communication between the devices, providing the highest level of security.
For the transport types, CUCM supports both TCP and UDP. TCP (Transmission Control Protocol) provides a reliable and ordered delivery of data, ensuring that packets are received in the correct order. UDP (User Datagram Protocol), on the other hand, does not have these guarantees but offers a lower latency, making it suitable for real-time communication.
Comparison of Device Security Modes and Transport Types
|Device Security Mode||Transport Type|
|Authenticated||Both TCP and UDP|
|Encrypted||Both TCP and UDP|
Choosing the right combination of device security mode and transport type depends on your specific requirements and the level of security you need. It is important to assess your communication needs and the sensitivity of your data to make an informed decision.
