A centralized auditing system receives an audit block containing one or more audit files generated by an audit agent running in an audited device. The audit block additionally stores a first digital signature corresponding to a previous audit block, and a second digital signature generated based at least on the one or more audit files and the first digital signature. After receiving the audit block, the auditing system verifies the integrity of the received audit block based on the second digital signature stored in the audit block and/or the first digital signature corresponding to the previous audit block. In response to verifying the integrity of the received audit block, the auditing system adds the received audit block to an audit register. Moreover, the auditing system adds the one or more audit files included in the audit block to an audit database.
