Cisco Capture The Flag - Meraki Version

Capture the Flag is a networking game that will allow you to gain hands-on experience with designing and operating cloud-based solutions with the Cisco Meraki platform.

Find it HERE (Until July 17th 2020) - An Online treasure hunt! Where the treasure is "things to put onto your resume."

After signing up, you log into an emulator of a Meraki dashboard.

This is how it looks forreal. I've used Meraki in demos before!

One of the clues is

"What is the name of the custom performance class configured at London’s MX which matches the metrics described?"

[metrics ommitted by runtcpip.com]

Then you go to the appropriate page and you look around; When you answer successfully, you get a nice,DOS-esque screen;

There are hints; Don't be ashamed to use them, even if you lose points. It's all a learning experience!

Even if said hints are a strange mixture of vague and obvious.

Change Access Point Radio Frequency somewhere in the 'Wireless' menu? Groundbreaking.

You don't lose points from clicking 'Read More Task Details'.

When even the hints have you stumped, there was an open WebEx chat where someone was on hand to help.

Shout out to Nate Austin for helping me with #18 - You can run APIs here, you don't need to download Postman if you're a beginner! I found where to put the API key myself and got the correct answer.

You can also get an e-mail with a summary of the "flags" you've captured.

Things I learned

Meraki has cameras!
Meraki appliances can be configured in different deployment modes.
When blocking with filters, site categories are updated dynamically.

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

If you're seeing this post, I'm helping you, and you probably have LI presence: React and share this post to help me in return. 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

Create a Simple Network (Packet Tracer) + A Walkthrough

Again; I've done this, but now there's so many new things, I'm doing it again. The truly new portions were...everything on the right side of this diagram; The cloud needed a coax connector and a copper Ethernet connector. It's all easy to install, turn off the cloud (Weird), install the modules. Getting the Cable section of Connections was an unusual struggle - The other drop down menu had nothing within. It required going into the Ethernet options and setting the Provider Network to 'cable', which is the next step AFTER the drop-downs. The rest was typical DHCP and DNS setups, mainly on the Cisco server down there. The post is rather short - How about adding a video to it? Find out what A Record means - This site says 'Maps a name to an IP address', which is DNS. So it's another name for DNS? You can change them (presumably in a local context) to associate an IP address to another name.

Securing Terraform and You Part 1 -- rego, Tfsec, and Terrascan

9/20: The open source version of Terraform is now OpenTofu Sometimes, I write articles even when things don't work. It's about showing a learning process. Using IaC means consistency, and one thing you don't want to do is have 5 open S3 buckets on AWS that anyone on the internet can reach. That's where tools such as Terrascan and Tfsec come in, where we can make our own policies and rules to be checked against our code before we init. As this was contract work, I can't show you the exact code used, but I can tell you that this blog post by Cesar Rodriguez of Cloud Security Musings was quite helpful, as well as this one by Chris Ayers . The issue is using Rego; I found a cool VS Code Extension; Terrascan Rego Editor , as well as several courses on Styra Academy; Policy Authoring and Policy Essentials . The big issue was figuring out how to tell Terrascan to follow a certain policy; I made it, put it in a directory, and ran the program while in that directory
