Gary’s DefCon Journal  

August 17, 2021

Day 1- 

Hey Blue Team Village! Guess who’s back, back again? Gary’s back, tell a friend. It’s check in day at DefCon and I am so excited I’m rapping Eminem. Why am I so excited? Because people are back at DefCon. Wonderful, lovely, vaccinated and mask wearing people. I checked in this morning and got my wristband. I still had Lennart’s Amex (he definitely should have noticed all the cat food I’ve bought) so I planned on going even bigger this year than last year. Stay tunaed to read all about my adventures. 




Thursday I listened to Abe give a talk called, “Logjamming: Tales of Inovation, Intrigue, & Shenanigans from Combining Data.” Which is good because I need some more tips and tricks in that area. Apparently a certain Graylog founder/ can opener doesn’t have time to entertain all my questions. I bet Abe will help a cat out. 

Questions- 


What kind of log sources can I ingest into Graylog?

 - Raw-TCP/UDP, Beats, CEF, AWS-FlowLogs-Cloudtrail-Kenisis, Syslog-tcp-udp, Plain TCP UDP


What Illuminate content packs are available? 

- 0365, Palo Alto, OKTA, Windows Events, Sysmon


What is the best way to get started with Graylog?

-the best way to get started is to download a deployment available, install via the docs 

-checkout the graylog community and our website for video content and howtos


Gary, do you use Graylog?
Yes, obviously, I have a very successful business with many logs to ingest. But would you believe that Lennart didn’t give me a discount on the product? And to think I let him live in my house and open my cans. 


Is there formal training on Graylog?

- Yes there are enterprise training modules available at academy.graylog.org 

- now Training is offered as part of a paid course for anyone.


Can you describe how Graylog scales?

-scaling is done via a cluster of Graylog Severs with Mongo DB, Elastic Search and the graylog application


How is your new dog sister?

Please don’t make me answer this. But here is a picture of the wretched creature to please all of dog loving simpletons. But be warned, it is rather hideous. 



Can I run Graylog in the cloud? 

-yes, Graylog Managed cloud offering, we use a new product in premise called Graylog Forwarder

that forwards your logs encrypted and compressed into the cloud securing them.



Azure AD logging? 

- yes when you have Microsoft E5/A licensing tier to allow these logs to be enabled.


Logging sources

- AD/DNS/ logging, utilizing winlogbeat, however with multiple AD servers 






Abe gave an excellent talk, but I did take a cat nap towards the end. I couldn’t help meowself. Then I went to check out the town on Lennart’s dime. I toured around Vegas in style and in fear. Cats do hate water after all, aww the things I will do for good content. The attention I get really sustains my ego. Thursday was such a big day for me that I only managed to fit in about 12 cat naps. I will have to strive to do better tomorrow. 



Day 2- 

I began my day by blessing the people with my presence a bit and did a couple laps around Defcon. It was nice to be able to collect all the free treasures. Keychains are my favorite, they are incredible to swat. I am putting in a request for laser pointers next year now. 


After exploring I was feeling rather catatonic and in desperate need for some sunbathing. I ordered a few tunatinis to help take the edge off of such a stressful week. Humans do not appreciate how hard it is to be a cat. The cabana was a bit of a splurge but I deserve it. After all, Lennart did adopt a mongrel without my knowledge. 


After my rest and relaxation I was ready to get going with some capture the flag. I believe my cat reflexes will really help me win. 


Unsurprisingly, I was able to win. Defeating you Plebeians was kitten’s play. No one saw me as a threat. Meanwhile I became King of Defcon. Please feed me tuna accordingly. We also learned that unfortunately, my party was cancelled. That’s right, the party was really for me. But I rallied because I am a benevolent ruler who can go with the flow. I did sit in the hotel room in my party hat for a bit, it just looked so good on me. In the end the party was moved from Saturday to Friday night. Good thing I got ready so early. It became a virtual event instead, which meant I was able to hit the tables for some craps. I won a lot of money that I will use to hire a good lawyer and sue Miller for trespassing, emotional damage, embezzlement, racketeering, and whatever I find in the legal textbook I am reading. 

Going Home- 

What a weekend. Wow, it was so awesome to see so many of you there. My personal highlight was my time at the cabana. I did not realize how much I needed that kind of relaxation. Ever since the mongrel invaded my home I have harbored a lot of stress. I hopped on my jet, no commercial flights for this cat, and headed home. I wonder if Lennart even knew I was gone. Well that is it for me from Defcon this year. Hope to see you all back again next year.
