Gateway to Hell – Network Basics for DBAs, DEVs and DevOps

New environments are increasingly based on a software-defined data center, both on-premises and in the cloud. However, more conventional approaches also require database administrators or DevOps teams to understand and handle the network stack. Knowledge of this basic technology is more relevant today than ever before – even if, at its core, it is mostly a creation of the 1980s and 90s.
With a twinkle in our eye, we answer the following questions, among others:
– What’s so great about the Classless Society?
– What does a salami pizza have to do with network technology?
– If Superman likes supernetting, who does subnetting?
– How do nuclear weapons affect network design?
– If my routes come from the GPS, what do I need a router for?
– Who has DNS in their DNA?
We would like to invite all DBAs, developers and DevOperators to rediscover the basics of network technology with us. Everything seen through the practical eyes of experienced, strictly practice-oriented database experts. The lecture is therefore aimed at experienced IT professionals who (only) have little to do with network technology in their day-to-day work and would like to widen their view.

Hard Road to Hardening: CIS Benchmarks and Linux Security for Beginners

This is our project report about hardening project systems running Linux as a backend for the Oracle Database. Being long-time Linux and Oracle professionals, out of the blue we found ourselves tasked with a strangely nontechnical technical issue. Despite all experience, we were bewildered by all that was to learn in the security domain, to put it mildly!

This is a story of criminal threats, self-imposed limitations, calculated risks, hidden dangers, familiar habits, external pressures, real-world challenges, practical applications, performance, overhead, tools, and the big question: Who will maintain this?

Join us, as we explore the journey towards enhanced security — and the trade-offs that come with it.
