Malformed Data

The Clearswift Gateway has a number of ways to handle 'malformed data'.

Malformed data is any information that is unable to be correctly read or processed by the Clearswift Gateway. This data could have been deliberately corrupted in order to disguise a threat, or might have been affected by an external process. Malformed data can be hidden in the structure of a document, in the content, or in meta data.

The Clearswift Gateway uses a number of standard specifications to define and detect instances of malformed data, in attachments, message headers and meta data. For example:

• The Detect Malformed Data content rule - detects and processes any malformed data contained in documents and media types
• The Structural Validation content rule - checks for any data that might have been appended for certain format types
