IT Systems To Functions HeatMap Tool

Just a sample of the beginnings of what an organizations map could look like The initial systems to functions heatmap tool concept was really brought to me in an engagement with Rippleworks and the amazing Anisha Vaswani.

SSH Honeypot Cowrie Session Video

I had a ssh honeypot running a few months ago for a couple of weeks and while most session playbacks are just rapid fire scripts from bots trying to plant crypto mining software, I did have a few humans kicking around in there. I had a colleague login and kick the tires and shared the video back to him. Here is the video to give you a sense of what the ssh session looks and feels like. Disclaimer...

Took me a while to work this through. It should have been pretty easy but the Jitterbit Formula Builder syntax is just different enough to be a little bit of a challenge. Basically, I had a need to take multiple fields from a Jitterbit connection and map them over to a multiple line large string text field. We were taking some data parsed into separate fields and just moving them into a big text...
