This paper compares the probability similarities between a cyberattack, the distributed denial-of-service, and the mathematical model of probability, Lévy walks. This comparison aims to explore the validity of Lévy walks as a model resembling the DDoS probability features. This research also presents a method, based on the Smirnov transform, for generating synthetic data with the statistical properties...
The domain name system (DNS) is an essential component of Internet. As it is expected to be used by all legitimate users and applications, generally there are less inspections, restrictions and filters on it. Botnets rely on this open component to accomplish their malicious operation. Therefore, to defeat the single point of failure and evade static blacklists and firewalls, they employ DNS-based...
This paper puts forward an automatically generated system of attack signature based on virtual honeypots, which adopts an open source software virtual honeypot-Honeyd, uses the plug-in-supporting function of Honeyd, and sets up Signature Generation System (SGS) to generate attack signature for Snort automatically. SGS carries out the intrusion rule extraction of data packets which have entered Honeyd...
Despite of the advances in the e-learning domain during the last decades, there is a lack of suitable mechanism to carry out assessment with the appropriate measures to avoid cheating. Current LMSs do not provide the needed features to check that the intended student is taking the online exam by himself, or even to know if he has spent the whole session time in front of the computer. This paper presents...
