DLP Use Cases for File Hashing
Exact Data Matching (EDM)
DLP solutions use file hashes to detect exact copies of sensitive documents. If a file's hash matches a known sensitive document, the policy triggers.
Document Fingerprinting
Beyond exact matching, DLP can fingerprint document structures. Hashing helps identify templates, forms, and structured documents containing sensitive data.
File Integrity Monitoring
Hash values can track whether sensitive files have been modified. Changes to hash values indicate the file content has been altered.
Allow/Block Lists
Create allowlists or blocklists of file hashes for DLP policies. Known-good or known-bad files can be identified by their hash values.
