Universities are increasingly becoming the target of cyber attacks. According to the Federal Office for Information Security (BSI), the current threat level is higher than ever before [1]. In view of this growing threat and the increasing number of corresponding attacks, the Ministry of Culture and Science (MKW) of the state of North Rhine-Westphalia (NRW) published an Agreement on Cyber Security at Universities (VzC) at the end of 2023. With a total of 12 measures, this serves as a basis for securing university networks. At the same time, the BSI regularly recommends targeted measures to defend against threats.

After sneaking into a network, attackers can remain undetected for months, collecting data, searching for sensitive material, or acquiring credentials. They can then use this information to roam around the IT infrastructure, to observe it and to snatch even more data. The more data is tapped, the more severe the consequences of the attack may be. To identify such attacks as early as possible, a good defence strategy is essential. An important part of such a strategy is so-called Threat Hunting. Read the rest of this entry »
