Abstract: The increase of the number of smart devices using mobile networks’ services is followed by the increase of the number of security threats for mobile devices, generating new challenges for mobile network operators. Signalling attacks and storms represent an emerging type of distributed denial of service (DDoS) attacks and happen because of special malware installed on smart devices. These attacks are performed in the control plane of the network, rather than the data plane, and their goal is to overload the Signalling servers which leads to service degradation and even network failures. This paper proposes a detection and mitigation mechanism of such attacks which is based on counting repetitive bandwidth allocations by mobile terminals and blocking the misbehaving ones. The mechanism is implemented in our simulation environment for security in mobile networks SECSIM. The detector is evaluated calculating the probabilities of false positive and false negative detection and is character ised by very low negative impact on un-attacked terminals. Simulation results using joint work of both detector and mitigator, are shown for: the number of allowed attacking bandwidth allocations, end-to-end delay for normal users, wasted bandwidth and load on the Signalling server. Results suggest that for some particular settings of the mechanism, the impact of the attack is successfully lowered, keeping the network in stable condition and protecting the normal users from service degradations.
