ToN IoT - The role of heterogeneity and the need for standardization of features and attack types in IoT network intrusion datasets

The Internet of Things (IoT) is reshaping our connected world due to the proliferation of the availability of small devices connected to the Internet and their communication technologies. Therefore, the study and research towards intrusion detection in the IoT domain has a lot of significance. Network intrusion datasets are fundamental for this...

Zero trust-architectuur op basis van implied trust-zones

Zero trust’ is een term die steeds meer draagvlak krijgt binnen de cybersecuritygemeenschap. Centraal achter het zero trust-gedachtegoed is dat er fundamenteel anders moet worden omgegaan met de beveiligingsarchitectuur van een organisatie en haar (IT) infrastructuur: van ‘trust, but verify’ naar ‘don’t trust, verify!’ [1]. In een zero trust...

A new approach for structural health monitoring by applying anomaly detection on strain sensor data

Structural Health Monitoring (SHM) systems help to monitor critical infrastructures (bridges, tunnels, etc.) remotely and provide up-to-date information about their physical condition. In addition, it helps to predict the structure’s life and required maintenance in a cost-efficient way. Typically, inspection data gives insight in the structural...

Flow-based detection of DNS tunnels

DNS tunnels allow circumventing access and security policies in firewalled networks. Such a security breach can be misused for activities like free web browsing, but also for command & control traffic or cyber espionage, thus motivating the search for effective automated DNS tunnel detection techniques. In this paper we develop such a technique,...

Run-time revenue maximization for composite web services with response time commitments

We investigate dynamic decision mechanisms for composite web services maximizing the expected revenue for the providers of composite services. A composite web service is represented by a (sequential) workflow, and for each task within this workflow, a number of service alternatives may be available. These alternatives offer the same...

Dynamic Profit Optimization of Composite Web Services with SLAs

In this paper we investigate sequential decision mechanisms for composite web services. After executing each sub-service within a sequential workflow, decisions are made whether to terminate or continue the execution of the workflow. These decisions are based on observed response times, expected rewards, and typical Service Level Agreement...

Hoe goed bent u 'in control' over de robuustheid van uw ICT-keten?

ICT-ketens worden enerzijds steeds complexer en anderzijds van steed vitaler belang voor de maatschappij en voor organisaties. Daarbij neemt ook het belang van robuustheid van ICT-ketens en de beheersing daarvan toe. De auteurs beschrijven een nieuwe methodiek waarmee de mate van beheersing van de robuustheid van ICT-ketens kan worden vastgesteld.

Intelligent overload control for composite web services

In this paper, we analyze overload control for composite web services in service oriented architectures by an orchestrating broker, and propose two practical access control rules which effectively mitigate the effects of severe overloads at some web services in the composite service. These two rules aim to keep overall web service performance ...
