Intelligent Network Service Optimization in the Context of 5G/NFV
Our contemporary society has never been more connected and aware of vital information in real time, through the use of innovative technologies. A considerable number of applications have transitioned into the cyber-physical domain, automating and optimizing their routines and processes via the dense network of sensing devices and the immense volumes of data they collect and instantly share. In this paper, we propose an innovative architecture based on the monitoring, analysis, planning, and execution (MAPE) paradigm for network and service performance optimization. Our study confirms distinct evidence that the utilization of learning algorithms, consuming datasets enriched with the users’ empirical opinions as input during the analysis and planning phases, contributes greatly to the optimization of video streaming quality, especially by handling different packet loss rates, paving the way for the achievable provision of a resilient communications platform for calamity assessment and management
Incidents Information Sharing Platform for Distributed Attack Detection
Intrusion detection plays a critical role in cyber-security domain since
malicious attacks cause irreparable damages to cyber-systems. In this
work, we propose the I2SP prototype, which is a novel Information
Sharing Platform, able to gather, pre-process, model, and distribute
network-traffic information. Within the I2SP prototype we build several
challenging deep feature learning models for network-traffic intrusion
detection. The learnt representations will be utilized for classifying
each new network measurement into its corresponding threat level. We
evaluate our prototype's performance by conducting case studies using
cyber-security data extracted from the Malware Information Sharing
Platform (MISP)-API. To the best of our knowledge, we are the first that
combine the MISP-API in order to construct an information sharing
mechanism that supports multiple novel deep feature learning
architectures for intrusion detection. Experimental results justify that
the proposed deep feature learning techniques are able to predict
accurately MISP threat-levels
