DESCRIPTION:Let's learn about L2 isolation with VLANs and dive into basic n
 etwork architecture with OPNsense. After playing a bit with IPv4\, let's d
 iscuss unicorn-issues IPv6 for your homelab-ing. Then expanding with WireG
 uard for simple inter-machine networks. Continuing\, we will take a look i
 nto Linux network namespaces and a few tricks you can do with your systems
  to bypass "security" - and also how to defend against it.

DESCRIPTION:So\, it is 2025 and mailservers are getting more and more repla
 ced by cloud-based solutions\, which promise to be easy and secure... But 
 what if you can just do it yourself? Hosting your private message server a
 nd applying common modern mailserver security practices on your own? This 
 talk wants to introduce a few common software solutions and introduce mult
 iplie techniques from an operators toolbox.

DESCRIPTION:You want to learn more about Linux permissions? This is the tal
 k for you. Let's learn about the basic UID/GID concepts in Linux and expan
 d into more complex ACLs. Then escalating on the "everything-is-a-file" co
 ncept and applying the learned security logic onto program behavior using 
 SELinux or AppArmor.
