The complexity of modern communication networks and innovative cyber-attacking methods make it difficult to automatically detect and prevent attacks. Software-Defined Networking (SDN) separates the forwarding of network traffic from the decision plane of the network and offers a central and programmable interface for the configuration of the network. In this paper, a novel approach to integrate end-to-end...
Industrial espionage through complex cyber attacks such as Advanced Persistent Threats (APT) is an increasing risk in any business segment. Combining any available attack vector professional attackers infiltrate their targets progressively, e.g. through combining social engineering with technical hacking. The most relevant targets of APT are internal enterprise and production networks providing access...
Establishing trust relationships between network participants by having them prove their operating system's integrity via a Trusted Platform Module (TPM) provides interesting approaches for securing local networks at a higher level. In the introduced approach on OSI layer 2, attacks carried out by already authenticated and participating nodes (insider threats) can be detected and prevented. Forbidden...
The deployment of devices at remote or distributed locations is a typical scenario e.g. in large enterprise networks or industrial applications. In the deployment of a device identification of the device and the establishment of security relations (trust) between the device and other elements of the infrastructure is crucial. Usually, the process requires either to pre-configure the device or to let...
