Basic Protection by Current Security Standards
Up-to-date software is the main instrument to protect devices which are connected to a network, especially the internet, like notebooks, desktop computers but also smartphones and tablets. Most important to keep up-to-date are the operating system and applications that communicate over the network, e.g. an internet browser or an e-mail application. But other out-of-date application software can be dangerous too because it might be another opportunity to infect your system, for example with malware disguised as media files which use bugs in a media player. Since updates or patches can not only improve security but also usability and stability of software, they should be installed regularly and in a timely manner. Devices with discontinued manufacturer support and without regular updates may only be used in the WWU network to a limited extent.
