Abstract
A method for cooperatively filtering data traffic in a communication network. The method includes: filtering the data traffic on the basis of first filter rules using a first security filter module; inserting a description of the first filter rules into the filtered data traffic; filtering the filtered data traffic on the basis of second filter rules using a second security filter module, taking into account the inserted description of the first filter rules. A computer program, a device, and a storage medium are also described.

A method for cooperatively filtering data traffic in a communication network, comprising the following steps:
- filtering the data traffic based on first filter rules using a first security filter module;
- inserting a description of the first filter rules into the filtered data traffic;
- and
- filtering the filtered data traffic based on second filter rules using a second security filter module, taking into account the inserted description of the first filter rules.
A device for data processing configured to cooperatively filter data traffic in a communication network, the device configured to perform the following steps:
- filtering the data traffic based on first filter rules using a first security filter module;
- inserting a description of the first filter rules into the filtered data traffic;
- and
- filtering the filtered data traffic based on second filter rules using a second security filter module, taking into account the inserted description of the first filter rules.
A non-transitory computer-readable storage medium on which are stored commands for cooperatively filtering data traffic in a communication network, the commands, when executed by at least one computer, causing the at least one computer to perform the following steps comprising:
- filtering the data traffic based on first filter rules using a first security filter module;
- inserting a description of the first filter rules into the filtered data traffic;
- and
- filtering the filtered data traffic based on second filter rules using a second security filter module, taking into account the inserted description of the first filter rules.
