The Central Log Server must be configured to off-load log records onto a different system or media than the system being audited.

Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. Although this may be part of the operating system function, for the enterprise events management system, this is most often a function managed through the application since it is a critical function and requires the use of a large amount of external storage.
