In other cases, there is a formal need-to-know determination. In addition to such a determination, Special Access Programs and Sensitive Compartmented Information may require additional investigation and adjudication of the prospective clearance holder. [citation needed]
SCI information may be either Secret or Top Secret, but in either case it has additional controls on dissemination beyond those associated with the classification level alone. In order to gain SCI Access, one would need to have a Single Scope Background Investigation (SSBI). Compartments of information are identified by code words. This is one ...
Some token service providers or tokenization products generate the surrogate values in such a way as to match the format of the original sensitive data. In the case of payment card data, a token might be the same length as a Primary Account Number (bank card number) and contain elements of the original data such as the last four digits of the ...
Data masking or data obfuscation is the process of modifying sensitive data in such a way that it is of no or little value to unauthorized intruders while still being usable by software or authorized personnel. Data masking can also be referred as anonymization, or tokenization, depending on different context.
Mutual authentication is a desired characteristic in verification schemes that transmit sensitive data, in order to ensure data security. [ 1 ] [ 2 ] Mutual authentication can be accomplished with two types of credentials: usernames and passwords , and public key certificates .
Data verification helps to determine whether data was accurately translated when data is transferred from one source to another, is complete, and supports processes in the new system. During verification, there may be a need for a parallel run of both systems to identify areas of disparity and forestall erroneous data loss .
In cryptography, a message authentication code (MAC), sometimes known as an authentication tag, is a short piece of information used for authenticating and integrity-checking a message. In other words, it is used to confirm that the message came from the stated sender (its authenticity) and has not been changed (its integrity).
The primary use of data sanitization is for the complete clearing of devices and destruction of all sensitive data once the storage device is no longer in use or is transferred to another Information system . [12] This is an essential stage in the Data Security Lifecycle (DSL) [1] and Information Lifecycle Management (ILM). Both are approaches ...
