Establishing a chain of trust in a system log

摘要

Embodiments include a method, system, and computer program product for acquiring a data repository, the data repository being associated with a log configured to receive metadata. Then, a content of the log with respect to at least one manipulation of the data repository is modified by adding first metadata of the metadata. Further, signatures that identify control statements configured to govern the at least one manipulation of the data repository are collected by adding second metadata of the metadata into the log.
