What are the three levels of inspection for DLP?

The correct answer focuses on the specifics of how data is inspected in a Data Loss Prevention (DLP) solution. The three levels of inspection—Magic Bytes, MIME type, and file extension—are fundamental in identifying and classifying files during the data transmission process.

Magic Bytes refer to the specific byte patterns found at the beginning of a file that help to identify its format regardless of its extension. This is crucial because a file’s extension can be misleading; identifying files using their underlying content rather than the name helps ensure accurate classification.

MIME type is a standard used on the internet to indicate the nature and format of a document or file. By examining the MIME type, DLP solutions can determine how to handle the file based on its intended use or content type.

File extension is another layer of classification that provides quick insights into the file's type; however, relying solely on this can be insufficient due to potential manipulation of file names.

These three inspection levels allow DLP systems to thoroughly analyze files to prevent unauthorized transmission of sensitive information, targeting the actual content rather than just superficial indicators.

The other options, while related to data processing and network protocols in different contexts, do not specifically pertain to the structured approach used in DLP systems for identifying and
