Cryptographic information may be at rest in some device or storage media. This may include copies of the information that is also in transit or in use. Information-at-rest (i.e., stored information, including information contained within a cryptographic module) shall be protected in accordance with Section 6.1 . A variety of protection mechanisms may be used. The cryptographic information may be stored so as to be immediately available to an application (e.g., on a local hard disk or a server); this would be typical for keying material stored within a cryptographic module or in immediately accessible storage (e.g., on a local hard drive). The keying material may also be stored in electronic form on a removable media (e.g., a CD-ROM), in a remotely accessible location, or in hard copy form and placed in a safe; this would be typical for backup or archive storage.
