Which levels of inspection does Zscaler DLP utilize for file type enforcement?

The correct answer is based on the specific methods Zscaler Data Loss Prevention (DLP) employs for file type enforcement. Zscaler DLP utilizes Magic Bytes, Mime Type, and File Extension to determine and enforce the types of files being transmitted over its network.

Magic Bytes refer to specific sequences of bytes located at the beginning of a file, which can help identify the file type regardless of its file extension. This means that even if a file is misnamed, Zscaler can still accurately recognize its true format.

MIME Type (Multipurpose Internet Mail Extensions) provides a way to indicate the nature and format of a file. Unlike the file name or extension, the MIME type is more reliable, as it’s transmitted in the HTTP headers and specifies what type of data is being sent.

Finally, the file extension is the suffix at the end of a filename that typically indicates its format (e.g., .pdf, .jpg, .docx). While it can provide a clue about the file’s content, relying solely on file extensions can be insufficient without validating the actual content of the file.

This combination of methods allows Zscaler DLP to effectively enforce policies for file types, ensuring that sensitive information is appropriately managed and that
