With a role in cyber security, the area of responsibility goes beyond internal IT and focuses primarily on the technical aspects of detecting and eliminating threats online. A lot of work is done here to secure companies online, especially preventively, and to protect them from external attacks.
In this process, the role before takes over the implementation of technological measures for prevention and threat elimination. The tasks thus include access controls, cryptography, rights management, firewalls, proxies, virus scanners, vulnerability management and much more. In addition, concrete knowledge about combating mailware and direct attacks should be available. Therefore, a degree in computer science is often a basic requirement.
The trend is that internal IT systems are more and more connected to the internet, therefore the areas of IT security and cyber security will merge more and more in the future. Nevertheless, and perhaps because of this, the area of cyber security remains an important role, which primarily takes on technical tasks and ensures information security together with other roles of IT security.
