Embodiments can provide a computer implemented method in a data processing system comprising a processor and a memory comprising instructions, which are executed by the processor to cause the processor to implement a system for network protection, the method comprising determining, by the processor, if an incoming connection comprising one or more packets has a false latency larger than a trigger latency; determining, by the processor, if an attack is currently in progress; and if the attack is in progress, injecting, by the processor, at least one of the one or more packets of the incoming connection or one or more packets of an outgoing connection with a false latency.

Identification of attack flows in a multi-tier network topology

Embodiments can provide a computer implemented method in a data processing system comprising a processor and a memory comprising instructions, which are executed by the processor to cause the processor to implement a system for network protection, the method comprising determining, by the analyzing unit, if an incoming connection comprising one or more packets has a false latency larger than a trigger latency; if the incoming connection latency is larger than the trigger latency, reporting, by the analyzing unit, the incoming connection as a suspicious connection; determining, by the analyzing unit, if an attack is currently in progress; and if the attack is in progress, injecting, by the analyzing unit, at least one of the one or more packets of the incoming connection or one or more packets of an outgoing connection with a false latency.

A computer program product for transmitting data flow in a network between two resources using a processing circuit to perform a method which includes obtaining a data record from a first resource, storing the data record and an associated data record identifier in a first memory, transmitting the data record from a first network to a second network, storing the data record and an associated data record identifier in a second memory, determining by an inline service provider whether the data record is suitable for transmission from a first resource to a second resource; based on determining that the data record is suitable for transmission by the inline service provider transmitting only the data record identifier stored in the second memory to the first switch and retrieving the data record stored in the first memory associated with the data record identifier for transmission to the second resource.
