Using cryptographic hashing provides a rigorous method for validating the integrity of log files by generating a unique hash. If the log file is altered in any way, the hash will change, indicating tampering. Digital signatures also ensure integrity and authenticity but may not cover all scenarios of log file management during an incident response. Access control mechanisms and regular backups are supportive measures but do not directly validate data integrity.
