True-file type detection

When Cortex Data Loss Prevention (DLP) scans a file, true file-type detection identifies the file based on its actual internal format rather than relying on its file extension.

This ensures consistent policy enforcement and prevents users from intentionally bypassing DLP rules by masking files.

• Accurate Enforcement: DLP recognizes the sensitive data inside the file and applies the matching data-in-motion rule, regardless of the file's current extension.
• Evasion Prevention: If a user renames a restricted document (for example, changing report.pdf to report.log), DLP still identifies the true file type as a PDF, scans the embedded sensitive data, and enforces the appropriate rule.
