Predefined Data Pattern
Predefined Data Pattern defines the default DLP (Data Loss Prevention) patterns and classify private and confidential data that should be regulated in accordance to regulatory compliance requirements.
Predefined data patterns are located in Data Protection > Policies > Data Patterns > Predefined tab.
FortiCASB identifies SaaS account activities on files with these predefined data patterns and alert the administrators.
For example, when a file containing Social Security Numbers (SSN) is accessed by a SaaS user, FortiCASB will notify the file owner or the administrator.
In 2023, additional data patterns are added with the support through FortiGuard, resulting a total of 147 data patterns with 5 pattern categories:
- Personal Identity Information
- Financial Information
- Legal Information
- Intellectual Property
- Malware and Ransomware
The maximum uncompressed/compressed file size that the data patterns supports is 20 MB.
For the latest data pattern updates, please refer to FortiGuard DLP updates.
