Lower processing and storage requirements makes tokenization an ideal method of securing data at rest in systems that manage large volumes of data.ДЄ further method of preventing unwanted access to data at rest is the use of data federation especially when data is distributed globally (e.g. This is achieved by keeping specific data fully or partially visible for processing and analytics while sensitive information is kept hidden.

Tokens require significantly less computational resources to process and less storage space in databases than traditionally encrypted data. This process does not alter the type or length of data, which means it can be processed by legacy systems such as databases that may be sensitive to data length and type. Tokenization is a non-mathematical approach to protecting data at rest that replaces sensitive data with non-sensitive substitutes, referred to as tokens, which have no extrinsic or exploitable meaning or value. Finally, only store the minimum possible amount of sensitive data. Periodic auditing of sensitive data should be part of policy and should occur on scheduled occurrences. Encryption also enables crypto-shredding at the end of the data or hardware lifecycle. Encryption keys should be stored separately from the data. Data encryption keys should be updated on a regular basis. Cryptography can be implemented on the database housing the data and on the physical storage where the databases are stored. Increasing encryption on multiple levels is recommended.

Encrypted data should remain encrypted when access controls such as usernames and password fail. The encryption of data at rest should only include strong encryption methods such as AES or RSA. Mobile devices are often subject to specific security protocols to protect data at rest from unauthorized access when lost or stolen and there is an increasing recognition that database management systems and file servers should also be considered as at risk the longer data is left unused in storage, the more likely it might be retrieved by unauthorized individuals outside the network.Дata encryption, which prevents data visibility in the event of its unauthorized access or theft, is commonly used to protect data in motion and increasingly promoted for protecting data at rest. The division of data at rest into the sub-categories 'static' and 'inconstant' addresses this distinction ( see Figure 2).Д«ecause of its nature data at rest is of increasing concern to businesses, government agencies and other institutions. These definitions could be taken to assume that Data at Rest is a superset of data in use however, data in use, subject to frequent change, has distinct processing requirements from data at rest, whether completely static or subject to occasional change.

The imprecise nature of terms such as вЂњconstantвЂќ and вЂњfrequentвЂќ means that some stored data cannot be comprehensively defined as either data at rest or in use. вЂњInactive dataвЂќ could be taken to mean data which may change, but infrequently. which never changes), regardless of its storage medium, is data at rest and active data subject to constant or frequent change is data in use.

While it is generally accepted that archive data (i.e. For example, some enterprise encryption gateway solutions for the cloud claim to encrypt data at rest, data in transit and data in use. Data at rest includes but is not limited to archived data, data which is not accessed or changed frequently, files stored on hard drives, USB thumb drives, files stored on backup tape and disks, and also files stored off-site or on a storage area network (SAN).' Дata in use has also been taken to mean вЂњactive dataвЂќ in the context of being in a database or being manipulated by an application.

'.all data in storage but excludes any data that frequently traverses the network or that which resides in temporary memory.
