What must be done to ensure the security of log files during transmission?

To ensure the security of log files during transmission, encrypting communication channels is essential. This practice protects the integrity and confidentiality of the data as it travels over the network. Encryption makes it extremely difficult for unauthorized users to intercept and read the log data, thereby mitigating risks associated with data breaches or unauthorized access during transit.

Using encryption ensures that even if the data is intercepted, it cannot be easily deciphered. This is especially important for sensitive logs that may contain personal information or critical security event data. Implementing secure protocols, such as SSL/TLS, can help achieve this encryption.

While basic authentication can add a layer of security, it does not protect the log data itself; it merely verifies user identity. Storing log files locally and reviewing them periodically are important practices for log management, but they do not directly address the security of the log data during transmission.
