Static Data Masking
Persistent data masking, or Static Data Masking (SDM) is the primary method of protecting specific data elements at rest. These "elements" are typically database column or flat-file field values that are considered sensitive. These fields may contain personally identifiable information (PII), protected health information (PHI), primary account numbers (PAN), trade secrets, or other private values.
The "startpoint" data-centric security product IRI FieldShield -- or the IRI CoSort product and IRI Voracity platform that include the same capabilities -- provide more data discovery and SDM functions for more data sources than any other data masking tool. They now also include a state-of-the-art re-ID risk scoring wizard.
Available per-field/column functions include:
- multiple, NSA Suite B and FIPS-compliant encryption (and decryption) algorithms, including format-preserving encryption
- SHA-1 and SHA-2 hashing
- ASCII de-ID (bit scrambling)
- binary encoding
- data blurring and generalization
- redaction (string masking)
- reversible and non-reversible pseudonymization
- expression (calculation / shuffle) logic
- conditional / partial filtering (omission)
- custom value replacement
- byte shifting and sub-string functions
- tokenization (for PCI)
You can also "roll your own" external data masking function. This allows you to call a custom field protection at runtime instead of a built-in function
Whether built-in or custom, you can apply functions conditionally to specific rows or columns, and across tables through protection rules you can define, store, and re-use. It is also possible to apply these functions in a dynamic data masking (DDM) context.
Create, run, and manage your data masking jobs in a free state-of-the-art GUI, built on Eclipse.™ Or, use the same, simple, self-documenting 4GL metadata defining your data layouts and protections in a command line environment.
If you have sensitive data in Excel, check out IRI CellShield. FieldShield supports many of the same encryption, redaction and psedudonymization functions as FieldShield.
If you have sensitive data in unstructured text, log or .pdf files, check out IRI DarkShield. DarkShield supports at least half the number of functions listed for FieldShield above.
Did You Know?
FieldShield is the award-winning, fit-for-purpose static data masking product for databases and flat files built on Eclipse and powered by IRI CoSort. FieldShield -- along with DarkShield and CellShield -- is also a member product of the IRI Data Protector suite, and is included with IRI Voracity total data management platform subscriptions.
Voracity users can run these static masking functions along with data discovery, integration, migration, governance, and analytic operations. For example, they can encrypt and sort data for safe bulk DB loads, or build a delta report or ETL job that de-identifies fields.
