The Research and Technology Transfer Centre of the Research and Academic Computer Network (NASK) – National Research Institute (NRI) has developed a cyber security system to help detect and suppress DDoS attacks. The FLDX system is based on the results of many years of scientific research including control theory, signal theory and machine learning theory.

DDoS (Distributed Denial of Service) attacks, unlike other types of cyber attacks, do not aim to break security, but to block access to the website and web servers.

Network infrastructure overload and loss of access to digital services are among the most serious and prevalent cyber security threats. Such incidents are increasing every year. According to NASK estimates, today already around 1/3 of website outages are caused by DDoS attacks.

The entirely new solution, developed by NASK researchers, is extremely fast and effective in protecting the availability of services in the web, regardless of whether the source of the threat is a volumetric DDoS attack or a sudden increase in user activity. Algorithms implemented in the system automatically identify and precisely isolate dangerous packet flows, and then limit their harmful impact on services and network resources.

The solution can be used to protect the state’s critical infrastructure, military network infrastructure and state administration, as well as a source of information on security incidents and a mechanism for suppressing selected types of threats.

The effectiveness and efficiency of the system has been confirmed by deployments in nationwide networks. FLDX was also awarded the Grand Prix of the ‘State Security Leader’ competition during the International Defence Industry Exhibition in Kielce.
