Selecting a content classifier

The Conditions tab of the custom policy wizard is used to add content classifiers or email attributes to the policy.

• Content classifiers are used to identify account numbers, credit card numbers, industry terms, and similar items as sensitive data.
• Attributes are used to identify email components to monitor. The available content classifiers and attributes are:
• Patterns & Phrases classify data by regular expression (regex) patterns, key phrases, dictionaries, and scripts. Regex patterns are used to identify alphanumeric strings of a certain format, such as 123-45-6789.
• File Properties classify data by file name, type, or size. File name identifies files by their extension. File type identifies files by their “magic number” (an internal identifier).
• Fingerprint files or directories, including SharePoint directories, and database records directly from a database table, Salesforce table, or CSV file.
• Use Machine Learning to provide examples of the data that you want to protect, so the system can learn from them and identify items of a similar nature.
• Set a Transaction Size to monitor transactions that exceed a size limit, such as email messages more than 10 MB.
• Set a Number of Email Attachments to monitor email messages containing multiple attachments.
• Set a Number of Email Destinations to monitor email messages being sent to multiple destination domains.
