Securing Terraform and You, Part 3 -- The Finish Line

9/20: The open source version of Terraform is now OpenTofu 

I swear, this is not a recurring series. The problem just -- finally -- got solved.

I went back to tfsec after seeing the simple start guide posted here, by Liam Galvin at Ghost Security.

There are two aspects of my code: 

  • Allow buckets starting with [word]
  •  deny buckets that don't start with [word].

 The initial guide only has "don't allow buckets that are exactly named this", but that's all I needed to actually get going!

The problems could have been;

  • The rego file and the terraform file don't play well in the same file. Having the options in two separate subfolders helped even though there was a command that I used to read both files in the same folder.
  • Trivy ... I don't know. Maybe the metadata setup was incorrect - but if it's set up as comments -- readable by the program but not acknowledged in the rego -- who knows. I can work on that in the future.
  • The code was similar though not exact to examples and code I puzzled together initially. 100% it could be wrong (also, ChatGPT didn't know how to write it either. Is this too new and the ChatGPT learning model doesn't know it? )
Remember - tfsec has been bought by Aqua Security, the people behind Trivy; This code could probably work if I put in the correct metadata tags and use the right command.

Connecting IoT Devices to a Registration Server (Packet Tracer, Cisco)

In Packet Tracer, a demo software made by Cisco Systems. It certainly has changed a lot since 2016. It's almost an Olympic feat to even get started with it now, but it does look snazzy. This is for the new CCNA, that integrates, among other things, IoT and Automation, which I've worked on here before. Instructions here . I don't know if this is an aspect of "Let's make sure people are paying attention and not simply following blindly", or an oversight - The instructions indicate a Meraki Server, when a regular one is the working option here. I have to enable the IoT service on this server. Also, we assign the server an IPv4 address from a DHCP pool instead of giving it a static one. For something that handles our IoT business, perhaps that's safer; Getting a new IPv4 address every week or so is a minimal step against an intruder, but it is a step. There are no devices associated with this new server; In an earlier lab (not shown), I attached them to 'H

Building, Breaking, and Building A CRM with Retool

 I like no- or low-code solutions to things. I've often wanted to simply push a button or move some GUI around and have the code implement itself.  I've thought about building something that's like a customer relationship management (CRM) system for keeping up with my network better than my little spreadsheet where I click links and then go like something. The general idea in this CRM Development is:  To have a GUI to add people to a NRM (Network Relationship Management).       Attach it to a database (MySQL is what I went with eventually using Amazon Relational Database service, but you can use PostGRES, and probably others).     Make sure components are connected to each other in the retool interface. This video is a good start. Watching the tutorial video, heard some SQL commands and went 'Oh no 😳" before going "Wait I know basic SQL", which is good, because you'll see.  When you get set up, there's a plethora of resources you can use -- Incl
