Learning about SNMP, and microinterview with Kevin Johnson

In an effort to educate ourselves for an upcoming interview, we sat down and talked about SNMP (Simple Network Management Protocol). We get into the basics, the ins and outs of the protocol, the different tools that use (or exploit) SNMP, and we talk about how to better secure your SNMP implementation. YOu should listen to this, because next week's interview will knock your socks off. :)

Finally, We end with a DerbyCon interview Mr. Boettcher snagged with our friend Mr. Kevin Johnson about how we need to regulate ourselves with regard to a code of ethics, before someone regulates us... When one 'white hat' can run code on a server he/she doesn't control (unpatched Shellshock) and thinks it's okay, where do we draw the line from what is right, and what violates the CFAA? Mr. Johnson looks for an answer with our Mr. Boettcher.

Keep Calm and take a tcpdump! :)

Tcpdump is just one of the tools that will make troubleshooting network issues, or testing applications, or even finding out what traffic is being generated on a host.  This podcast is to help you understand the Tcpdump program, and how powerful it is...

Part 2 with Jarrod Frates - how pentesting is important

Part 2 of our interview with Jarrod Frates (FRAY-tes). We ask him about the value that a pentest can create, the way that that 'perfect' pentest can change culture and help create dialogue.

Also, we talk about how to take your automated testing info and then shift gears to manual testing... when to stop doing automated testing, and do the manual testing.

Hope you enjoy, have a great week!

DerbyCon report and Shellshock news

We went a little off the beaten path this week. I wanted to talk to Mr. Boettcher about his experience at DerbyCon, and we ended up having another friend of ours who also attended DerbyCon, Jarrod Frates, join us for a bit of discussion. We discussed several talks, and even spent a little bit of time talking about ShellShock and it's larger implications for those programs that are ubiquitious, yet are not being audited, like bash.  (The llama graphic will make more sense next week...) :)
