Only 7% of German companies are prepared for AI

8.000 managers in 30 countries took part in the “AI Readiness” study and commented on the use of AI in the company. Germany is ill-prepared. IT infrastructure and cybersecurity are cited as the highest priority areas for the use of AI. 14 percent of companies worldwide are fully prepared to use AI - in Germany only 7 percent. This is shown by Cisco's first AI Readiness Index, for which over 8.000 companies were surveyed, more than 300 in Germany alone. Compared to seven other EU countries and Great Britain, Germany is...

Learn to hack to prevent attacks

“Ethical hackers” hack into corporate networks to identify security holes before attackers find them. This can be learned in a course. Cyber ​​specialists are in short supply. Current studies assume a need for more than 100.000 security employees in companies and authorities - in Germany alone (Cybersecurity Workforce Study; (ISC)2 Research). They are urgently needed to build a resilient security structure for the business location. Hacking as a course offering cyber specialists also offers excellent prospects on the job market. One of the more unusual areas of activity in these future professions is “offensive cybersecurity” (OffSec). Here you will find…

B2B Cyber ​​Security ShortNews

IT security is one of the areas that is currently being changed by AI. On the one hand, AI helps criminals make attacks more efficient, sophisticated, scalable and evade detection. On the other hand, security departments and law enforcement agencies receive new tools to detect and attribute illegal activities more effectively. Cisco Talos analyzed the current state of this race and identified the following trends: Increasing danger Thanks to AI, cybercriminals require fewer and fewer people and knowledge for attacks and software development. This both lowers barriers to entry, so that the number of criminals and attacks increases, and...

According to Cisco Talos analysis, this type of attack was responsible for a quarter of all incidents investigated by the Incident Response Team in the first quarter of 2023. At the same time, the proportion of detected ransomware attacks fell from 2023% to 20%. However, the cyber researchers are not giving the all-clear: Because a fifth of all observed threat activities were…
