Petr Pelc - Be Selective, Be Fast

Let´s explore how selective data and rules can shorten the time from collection to critical findings. The aim is to identify suspicious indicators and help incident responders decide quickly if deeper investigation is required.  

16:00
Pavel Mazánek & Vojtěch Vokálek - Can your SOC see me?

Does having the right security tools mean that a real attack will be caught? Let’s take a look at SOC operations from both the attacker’s and defender’s perspective, see how threat modelling can help identify relevant threats and attack paths, and how Purple Teaming validates scenarios in practice and reveals what needed to be and what actually was properly detected, correlated, and mitigated.

Hung Ngo
IT Security Specialist
Hung “Hungo Boss” Ngo is a cybersecurity specialist focused on security monitoring, detection engineering and threat intelligence. He teaches with Czechitas, co-organizes BSides Prague and speaks at security events, making complex topics accessible with practical insight and nerdy humor.

There’s something for everyone at Security Days. A cyber junior—whether a student or simply an enthusiast captivated by the field of cybersecurity—is interested in all the latest information, wants to meet others in the field, and learn from the best. Cybersecurity specialists who want to continue expanding their knowledge, specialize further, and gain a more comprehensive perspective. They want to discuss the latest developments and technologies. Or perhaps an expert. They’re interested in hearing other experts’ views on a given issue and want to engage in constructive debate with them. During the event, they also want to meet with less experienced professionals to share their know-how.
