Today's IT systems used by corporations are characterized by a steadily growing number of computers and other devices. Furthermore, virtually all devices are connected via networks. Lastly, the complexity of dependencies between computers and services is growing. The named reasons make it difficult to understand, protect and maintain the functionality of computer networks already today.
An additional difficulty is that today's IT systems cannot be shielded anymore from the outside world. One important reason is the spatial expansion of many computer networks which might lead to physically exposed hosts that might be compromized by adversaries. Another reason is the amount of interaction between entities within the (secure and trusted) own IT system and other (hazardous and untrusted) entities located in the outside world.
To reduce operational costs, networks and computers are consolidated today using various types of virtualization technologies, for instance hardware or network virtualization (VLAN, VPN, SDN, etc.). Formerly physically separated machines and networks are now isolated from each other by a thin layer of software that abstracts over the hardware. If the security offered by the virtualization layer fails, the security of the entire IT system can be weakened, as attacks can spread more easily between components.
The changes listed above can even be witnessed even in the very security critical main scenarios addressed by the DecADe project: IT systems found in airplanes and automobiles.
In the project we focus on solutions for permanent and comprehensive monitoring of the IT system, early detection of attacks, and a concise assessment of the current threat level of the entire IT system. The project understands the growing amount of devices and connectivity not only as a problem but also as a chance that only needs to be used in order to increase the security level of the IT system. The projects main idea is that components of the IT system with free capacity (CPU, memory, bandwidth, etc.) shall be leveraged to monitor the behavior of other components in order to find anomalies in the entire IT system.
