Usage Guidelines

The Central AP can filter a decompressed file based on file content if the decompression depth of the file is smaller than or equal to the decompress-depth value. Based on the configured decompression depth, the Central AP can process files with multiple decompression layers.

The Central AP detects compressed file by flow and implements decompression and content security detection simultaneously. If a data flow contains threat information, the Central AP processes the flow based on the content security configuration. If the data flow is secure and the decompression depth of a file exceeds the specified value, the Central AP will take the action set using the file-frame decompress depth action command for the situation in which the maximum decompression depth is exceeded:

  • Allow: Allows the file transfer. This is the default action.

  • Alert: Allows the file transfer and generates a log.

  • Block: Blocks the file transfer and generates a log.

Example

# Set the maximum decompression layer to 5.
