The purpose of executing the provided CLI commands, which include setting the log-checksum to md5- auth, is to ensure the integrity of the log files. This setting is used to record the MD5 hash value of log files, which is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value. By using MD5 authentication, FortiAnalyzer ensures that the log files have not been altered or tampered with during transit, thereby verifying their integrity upon receipt. This is not related to encrypting log transfers, scheduling reports, or creating secure channels for OFTP (Over-the-FortiGate Protocol) processes.
