Networking. I recently spoke at Interop 2016 in Las Vegas, and while I was there I scribbled down some notes pertaining to how decomposing applications into microservices-based architectures was similar in some respects to decomposing networks into an overlay network and an underlay (physical) network. Servers/Hardware.

Fast, GB wifi leads Elliot to discover a TOR network which leads him to the onion routing protocol. Ohfeld: After elevating our privileges to it, we could inspect the firewall rules.

Networking. The use of VMware NSX for microsegmentation is a really popular use case, and so the topic of scripting distributed firewall (DFW) rules often comes up.

Plus, by default, the administrator account on Windows computers doesn’t lock out. Maybe you have a SIEM, and you identify these attempts in a daily report and then address it by blocking the source IP address in your IPS or firewall. The evildoers can brute force the administrator account until the cows come home!

After testing Unix, Miller went to fuzz Windows NT and other systems. And while it’s not Windows, it can be added.

So it's it's a fun time.
