Common use of Purging Clause in Contracts

Purging. This type of media sanitization is a process that protects information from a laboratory attack. The terms clearing and purging are sometimes synonymous. However, for some media, clearing is not sufficient for purging (i.e., protecting data from a laboratory attack). Although most re-writeable media requires a single overwrite, purging may require multiple rewrites using different characters for each write cycle. This is because a laboratory attack involves threats with the capability to employ non-standard assets (e.g., specialized hardware) to attempt data recovery on media outside of that media’s normal operating environment.
