Cybersecurity

In a nearly completely interconnected world, cybersecurity is a main concern for governments, corporations and individuals. The Internet is a technological space where criminals operate with little prosecution, and where the application of laws is restricted by the absence of national boundaries. Even those expected to be the good guys can be little trusted. Governments and Internet corporations take advantage of their privileged situation, by accessing the private information of individuals and competitors. Big databases with detailed information on individuals are stored throughout the Internet, and security breaches make this information available in black markets in the deep web. Still, each day we rely more on the cloud and the free services on our mobiles, PCs and the Internet. Even industrial processes and critical infrastructures are getting more connected, sometimes without an adequate concern for security. The cyberspace can be so harmful that cyber warfare is considered the fifth domain of warfare.

Clearly, cybersecurity is a hot topic for today and future life, which makes it a main topic in university research and teaching. I belong to the Network Engineering and Security Group and to the UGR Cyber Security Group, and offer courses on cybersecurity in Degree and Master level. I specialize in security event detection, mainly with multivariate techniques.
