About CyberSec


My name is Tobias, and I started as a developer decades ago. I have held many different positions, including team lead, department head, board member, and self-employed consultant. However, everything had one thing in common - it was always about IT. Over the last 20 years, I learned a lot about security, privacy, and how to manage them. I steadily expanded my knowledge; however, there will still be much to learn.

I regularly attend cybersecurity conferences and events. Furthermore, I did a MicroMaster in Cybersecurity at RIT (Rochester Institute of Technology) and the Unlocking Information Security program at Tel Aviv University. I concluded that I want to share my knowledge with others, especially newcomers and interested parties. Therefore, I set up this website to provide a starting point for everyone interested in this topic.

I have lined up many slide decks, which I will publish in the upcoming months, and some cybersecurity tools to support you in your daily business. I wish all newcomers and readers of my slides all the best.

Frequently Asked Questions

Cybersecurity or IT security protects networks, computer systems, and devices from theft or damage to their hardware and software or the data they process and from disruption or misuse of the services and functions they provide. The information is both private and business, which in turn may be personal. Overall, cybersecurity is often (but not only) directed against cybercrime. Among the most significant challenges is the lack of global, centralized cybersecurity institutions and global agreements and regulations to detect and combat cybercrime and bring about cyber resilience.
A cyberattack can lead to identity theft and blackmail attempts on an individual level. Personal data, such as credit card details or family photos, can also be stolen. Critical infrastructures, such as power plants, hospitals, and financial service providers, are essential to the functioning of our society. In addition, industrial espionage is one of the most significant risks for companies.
