High-security key management systems, presented by leading security providers at CeBIT 2011, ensure that only authorized users can access data stored in the cloud. Private users are increasingly purchasing IT and Internet security services provided directly from the Internet. Security-as-a-service, for example, is often provided free of charge or for a small extra fee for new operating system licenses, in the form of anti-virus protection and firewalls. CeBIT 2011 also included displays of the latest protection software for today’s smartphones, which are increasingly exposed to hacker attacks due to their rapid growth in use. National governments also face IT security challenges: BITKOM reported that 78 percent of all German Internet users would like to see more government protection on the Web, particularly against terrorism and crime.
