Computers and internet access are now an integral part of our everyday lives. We use them not only for work, but also for private purposes. Whether it’s work-related documents, conversations with colleagues, friends and family, bank documents or the exchange of private photos; none of this should be visible to everyone.Whoever uses such technologies should also protect themselves. In order to protect yourself, an efficient password protection is essential.

Social Engineering – or: How we get tricked
Sometimes you just can’t say “no”. When the fundraising rescue workers are at the front door or in the pre-Christmas season the opportunities to do a good deed one more time this year are increasing. Of course we are happy to help, for we are social beings after all. However, this humanitarian side of us is being exploited increasingly. Social engineering aims to motivate people to do things they would not do under normal circumstances. This manipulation occurs everywhere – digitally, as well as in the real world.

Statement on attacks on high-performance computing systems
Several high-performance data centres throughout Europe are currently victims of cyber attacks. Some centres have therefore blocked the access to their computing capacity at least in parts due to security incidents to protect against (further) attacks.

Sicher surfen dank des richtigen Browsers
Wer im Internet unterwegs ist, kann bereits bei der Wahl seines Browsers einiges falsch machen. Obwohl die Hersteller von Browser stets versuchen ihre Programme so sicher wie möglich zu entwickeln, können sich immer Sicherheitslücken enthalten. Diese Sicherheitslücken im Browser können besonders problematisch sein, da Daten in der Regel auch aus nicht vertrauenswürdigen Quellen bei Nutzung eines Web-Browsers geladen werden können. Diese Daten können ebenfalls sogenannte Schadsoftware (wie zum Beispiel Viren, Trojaner usw.) enthalten. Es gibt jedoch Möglichkeiten diese Gefahren aus dem Weg zu gehen und die Auswahl eines sicheren Webbrowsers ist hierbei von großer Bedeutung.

According to the Federal Office for the Protection of the Constitution (BfV), both universities and research institutions are in danger regarding them.
