Free CompTIA Security+ SY0-601 Practice Question

Signing log messages with a digital signature ensures the integrity and authenticity of the log data by allowing the verification of the log source and whether it has been tampered with in transit. Timestamping provides a record of when events occurred but does not ensure data integrity. While encryption protects the confidentiality of log data during transfer, it does not directly ensure the integrity or authenticity of the data itself. Using a strong hashing algorithm, without a comparison mechanism or digital signatures, would not safeguard against tampering during transit.
