What is the role of Magic Bytes in Zscaler DLP?

Magic Bytes play an important role in the functioning of Zscaler Data Loss Prevention (DLP) by helping to identify specific file types. These are unique sequences of bytes that appear at the beginning of different file types, essentially serving as digital fingerprints that can accurately recognize the format of a file.

When Zscaler's DLP system scans files, Magic Bytes allow it to quickly determine the nature of the file being processed. This identification is crucial for ensuring that appropriate policies are applied based on the type of content being transmitted or accessed. By accurately identifying file types, Zscaler can enforce security measures more effectively to protect sensitive information.

In contrast, roles and permissions are related to access control for users and are not part of the file identification process. File content inspection focuses on analyzing the inner data of the files rather than recognizing the file type itself using Magic Bytes. Encryption of sensitive files is a separate process aimed at securing data but does not relate to the identification of file types using Magic Bytes.
