An Anki deck for Cisco Cyberops Associate CBROPS 200-201

I’ve recently been going through the Cisco Cyberops NetAcademy course as part of a TAFE unit I am doing at the moment. While working through the e-learning I took a bunch of notes, and then over the weekend I turned them into an Anki deck to help me prepare for the final exam. I’m actually unsure if I’ll bother with the certification exam, but this seemed like a more useful and reusable way to prepare than just reading and writing private notes.

The Man Who Broke Capitalism

With Cisco announcing that they no longer need 12% of their staff this calendar year (5% in February, and another 7% in September), I am left wondering what is so terribly wrong with American Capitalism. Interestingly at about the same time someone recommended I read this book, so here we are -- seeking to understand the behavior of our corporate masters once more. This book starts with this quote: To understand a civilization, consider its heroes. Which is telling because its so true. I think it also works for organizations -- if you want to see the values of an organization, don't look at what they say, look at who they promote and idolize. That's really the author's point though, so I shouldn't take too much credit. It's clear from the start that the author doesn't like Jack Welch or his leadership of General Electric and that he thinks Welch's legacy is toxic. Honestly though, he makes a pretty convincing argument that leaves me not being a huge fan either and certainly GE didn't survive the experience of Welch and those he chose to replace him upon retirement. It is asserted that Welch had three main maneuvers in business: downsizing;…

Cisco CyberOps Associate: Official Cert Guide

I don't think I've really reviewed a technical book here before, but I read the thing so I guess I should. This book is the certification guide for a "Cisco CyberOps Associate" certification, which is what they now call the CCNA Security qualification. Its a relatively junior certification, qualifying you to be a level one operator in a Security Operations Centre (SOC). I read this book because I took a Cisco NetAcad course for the associated certification in the second half of 2022 (although it has continued to be a thing I plug away at in 2023). That was mainly motivated by a desire to more about a field that is clearly important, but hasn't been core to my personal career. This book is reasonably well written and readable -- I'd read a chapter in the evening after work and its wasn't a huge chore to churn though. I certainly learned things along the way, even if the certification seems to suffer from a desire to have everyone rote learn a lot of acronyms, which seems like a common ailment in the industry (AWS Certified Cloud Practitioner, I'm looking at you). My main critism is of the qualification itself, which…

Configuring a spa3000 or spa3102

I've had a spa3000 for a long time and then it blew up. That meant I had to replace it with a spa3102, but without being able to refer to the configuration I had on the spa3000. It wasn't too bad, although the software on these devices is truly terrible (even with a modern firmware). Some pointers: Use the WAN port on the spa3102, even if you're only plugging in one ethernet port. Get firmware from Cisco. You can upload this to the spa3102 by putting it on a web server and then hitting http://SPA3102_IP/admin/upgrade?http://yourwebserver/firmware.bin. Then follow the instructions here. When you have problems with the dial plan, realize that Chris Yeoh has already solved this and go here. Finally, fix hangup detection by stealing the config line from here. Job done. Of course, there's no way to backup the config on one of these devices, so I am sure I will be back here again.
