To ensure secure transmission of log data over the network, particularly when dealing with sensitive or critical information, using TLS (Transport Layer Security) for encrypted communication between network devices and syslog servers is necessary:
Secure Logging Setup: When configuring an ArubaOS-CX switch to send logs securely to a Syslog server, specifying the server with the TLS option ensures that all transmitted log data is encrypted. Additionally, the switch must have a valid certificate to establish a trusted connection, preventing potential eavesdropping or tampering with the logs in transit.
Other Options:
Option B, Option C, and Option D are less accurate or applicable for directly encrypting log data between the device and Syslog server as specified in the company policies.
