DFA-AD: a distributed framework architecture for the detection of advanced persistent threats

Advanced persistent threats (APTs) are target-oriented and advanced cyber-attacks which often leverage the bot control and customized malware techniques in order to control and remotely access valuable information. APTs generally use various attack techniques to gain access to the unauthorized system and then progressively spread throughout the network. The prime objectives of APT attacks are to steal intellectual property, legal documents, sensitive internal business and other data. If an attack is successfully launched on a system, the timely detection of attack is extremely important to stop APTs from further spreading and for mitigating its impact. On the other hand, internet of things (IoT) devices quickly become ubiquitous while IoT services become pervasive. Their prosperity has not gone unnoticed, and the number of attacks and threats against IoT devices and services are also increasing. Cyber-attacks are not new to IoT, but as the IoT will be deeply intertwined in our societies and lives, it becomes essential to take cyber defense seriously. In this paper, we propose a novel distributed framework architecture for the detection of APTs named as distributed framework architecture for APTs detection (DFA-AD), which is a promising basis for modern intrusion detection systems. In contrast to other approaches, the DFA-AD technique for detecting APT attack is based on multiple parallel classifiers, which classify the events in a distributed environment and event correlation among those events. Each classifier method is focused on detecting the APT's attack technique independently. The evaluation results show that the proposed approach achieves greater effectiveness and accuracy.
