The total number of vulnerabilities continues to rise. If we had to rely on just CVSS for prioritizing those vulnerabilities, we have an enormous hard time to remediate all of them. In this talk, we’ll explore the critical gaps in CVSS-based prioritization and discuss why factors like exploitability, asset criticality, and real-time threat intellig…

This workshop is especially for all attendants who are not Dutch natives. In an exact and logical manner I will guide you through the syntax and semantics of the Dutch language, from sounds (the famous 'ggh' and vowel inventory) to gender of nouns and word order. There will be simple illustrations to help you get a grip on the language and bluff yo…
