Network Security

We are actively working on security protocols and methods for authentication as well as access control. To evaluate security properties, we also apply formal methods like model checking. We work with new protocols or modifications of existing protocols that use hardware security chips as the Trusted Platform Module (TPM) or Smart Cards.

Protection against DoS Attacks

Today (Distributed) Denial of Service Attacks are a major threat to the internet. In the past years there were attacks against the Internet infrastructure (i.e. DNS root servers), various services and companies and even against private persons using specific services (i.e. XBOX live). We are researching different ways to mitigate this threat.

Some networks are specially vulnerable against DoS attacks, for example if a core service that other services depend on has only limited capacity available. An attack against such a service will also affect dependend services. We are working on methods to check network and service topologies for such weaknesses.

Defense against ongoing attacks is easier if the defender has the possibility to flexibly re-configure his network topology. We are working on virtualization techniques that allow to change the network on the fly to limit the consequences on an attack.

Another research topic is the defense of HTTP-Servers by redirecting traffic between the client and multiple proxies. This way the attacker has to spend more resources to cause load on the server.

Honeypots, Malware Analysis and Intrusion Detection

In order to protect networks against Distributed Denial of Service Attacks understanding the mechanisms which are used to conduct these attacks is crucial. 

Our research activities therefore deal with the investigation of malware and botnets. We employ different kinds of honeypots in order to collect worms and other kinds of malware. All collected malware is automatically analyzed in sandbox environments in order to gain knowledge about its functionality and the botnets which are build with it. Using the results of our analysis enables us to enhance our traffic analysis and intrusion detection methods.

Network Access Control and Applications of Trusted Computing Technology

We work on authentication and authorization in various areas of networking. Peer-to-Peer networks and other self-organising systems, Web Services, and sensor networks are some examples. Especially in the context of (partially) self-organising systems, we investigate solutions that go beyond classic X.509 PKI or shared key infrastructures.

To this end, we develop cryptographic protocols, especially for authentication and conduct security analyses. One way to do this is to apply methods of model checking. We also adapt yet unprotected applications and services to be able to use standardized state-of-the-art security solutions (TLS, IPSec, WS Security, XACML, …) with them.

We also work on security solutions that use the Trusted Platform Module (TPM) technology. One use-case for TPM is  the secure storage of keys. Users cannot interfere and copy keys to insecure locations. The same is true for attackers who might want to get hold of the key to attack the network and its services. We also investigate Remote Attestation with the help of TPM. Remote Attestation allows to signal to another party that only a certain set of applications and a certain version of an Operating System (OS) is running on a computer. The primary usage is to avoid that worms, trojan horses or users of the system comprise its security by installing attack software. This is especially useful in business settings where even priviledged users could be attackers that need to be stopped.
