The Fraunhofer Institute for Secure Information Technology SIT offers an extensive know-how in the field of network security including the following topics:
Network Technologies: Network security is a very diverse and complex topic. A profound expertise of the underlying network technologies is essential for a holistic consideration of the security in network structures. Fraunhofer SIT possesses a well-established expertise concerning various wired as well as wireless network types of every scale, amongst others Ethernet-LAN, WLAN, peer-to-peer or mesh/ad hoc networks up to GSM (2G) / UMTS (3G) /LTE (4G) / 5G etc. Besides classical methods of protecting both network components or points of access, for example by VPN, firewalling etc. special fields such as Layer 2 security and Trusted Network Connect (TNC) are also taken into consideration.
Future Networks and Software Defined Networking (SDN): Being a research institution one of the primary objectives of Fraunhofer SIT is the development and evaluation of security features for both state-of-the-art and future network architectures or concepts, such as Software Defined networking, Future Internet, NGN / Future Networks, IMS (IP Multimedia Subsystem).
Multimedia Communication: Real-time communication with its vast variety of media, for example Voice over IP telephony, is one of the major fields of application within modern data networks. Thus, Fraunhofer SIT analyzes security implications of multimedia communications, including Unified Communications and associated protocols like SIP, H.323 and (S)RTP. Also the court-proof transfer and archiving of voice or video data streams is considered, including media conferencing.
Attacks from inside a company are a seriously underestimated threat for internal network infrastructures. Besides comprehensive analyzes of potential attack scenarios Fraunhofer SIT offers the implementation of standardized protocols such as IEEE 802.1AE in conjunction with the development of new security related features and services.
