Compressed files provide a number of special security concerns. Compressed files can
be
password-protected or encrypted, can harbor so-called "zip-of-death" security risks,
and
can contain numerous compression layers.
Compression types
Cloud App Security extracts and scans files compressed
using the most popular compression types (listed below). Cloud App Security also checks for malware "smuggled"
within nested compressions. Example: An infected file that is zipped,
ARJ-compressed, MS-compressed, and zipped again.

NoteCloud App Security supports scanning up to 5 recursive
compression layers maximum.
