I recently got a hold of a Cisco Secure Firewall 1210CE to replace my 1010 in the lab. It was pretty simple to onboard to Security Cloud Control for cloud management. youtu.be/J63QIZJCWrY?...

Happy New Year!

I wish all my network buddies a happy and more importantly “quiet” holiday season.

My lab firewall at home is managed by a Cloud-Delivered FMC in Cisco’s Security Cloud Control. In this video I spend time upgrading it to the latest Gold Star version 7.6.2.1. youtu.be/HQwZtT5gt_E?...

The use of firewalls has evolved over the years, from the perimeter to now being intertwined into the network. In this video, we do some white-boarding for some basic firewall use cases. youtu.be/yjMx5WVP5Vk?...

It’s Monday, so may your emails be way lighter than your coffee.

New episode is here. Ep 164: Oak Cliff Swipers This one is guaranteed to make your head shake in disbelief. darknetdiaries.com/episode/164

Firewalls have evolved over the years, but it has felt like a generation since the industry started using "Next Gen FW". Hybrid Mesh Firewall is what orgs are looking at now. Let’s focus on one piece of it, which is the firewall. youtu.be/-jtenKwmYG8?...

No laptop to open today.

I setup Cisco TrustSec in the lab using Identity Services Engine 3.4. With TrustSec, the focus is on segmenting with identity and not the IP address. youtu.be/9WZhE7BUjA0?...

For those running Cisco Catalyst 9800 series wireless controllers, you can run your config through the Wireless Config Analyzer for some best practices. youtu.be/Mgz85huSEwI?...

As organizations continue to deploy wireless solutions, they can’t forget about the wired side. Security is still needed on those switch ports and you should know what devices are connected. Cisco ISE can help with the visibility and control for wired devices as well. youtu.be/GlA_xW1jDdQ?...

Some hobbies can be expensive.

The Catalyst 9200L I upgraded in the lab last video, I now make the connection up to the Cisco Meraki Dashboard in order to use the Cloud CLI. youtu.be/mEEOCP1WkHI?...

Catalyst 9200L switches can be supported in the Meraki Dashboard even while running IOS-XE code. The first thing to do is upgrade to the required code: youtu.be/AqMNminqSsY?...

I was messing around with Veo 3. It’s interesting the stuff you can create from text to video. Here a cheesy security video for you :) youtu.be/AUslKFJaHKA?...

The sounds of Network Engineering.

Segmentation is not just a check box that you check and you are done. It involves different solutions, layers that you have to take into consideration. In an effort to make things dynamic and scalable, Cisco Identity Services Engine can help orgs implement TrustSec. youtu.be/BElQ_95Sg-g?...

Happy Father’s Day!

As soon as the pickup notification came…I walked over to my car and drove carefully through the streets following all rules of the road.

Last weekend I spent some time adding a Cisco Meraki MS130-12X to the lab. It will eventually replace an MS220 that is going End of Support soon. Join me for another episode of Weekend Maintenance! youtu.be/5VcuN-Mi6-8?...

Today’s schedule is cutting the grass because my neighbor cut his first and CCDE studies.

Check out this episode of Talk Time - Conversations That Matter. We spend some time talking about everyone’s favorite subject: Artificial Intelligence. youtu.be/HVTdFHK4WIg?...

I spent some time this Saturday doing some maintenance in the home lab. I swapped out a 3802 AP and upgraded code on the wireless controller. youtu.be/nNuas7EKp3Q?...

The weather keeps getting better! I need me some sun ☀️

Tiny coffee time!

History!

Patching and upgrades are important for a healthy <insert technology here>. This week I move the lab from Cisco ISE 3.3 to 3.4. youtu.be/w_Ae4t1wEvk?...

Cisco ISE can be used to control and manage admin access to network devices like your switches and routers. It uses TACACS+ to Authenticate, Authorize, and provide Accounting for the users who are logging into those devices. youtu.be/Q5JZQCuQaB8?...

Let the guest access fun continue! In this video, I create an SSID to be used for sponsored guest access with Cisco Identity Services Engine. youtu.be/vQF41fa4Nx0?...

Seems legit!

Happy Easter to those celebrating!

Studies: Onward to 15 hours of BGP videos.

Guest access is something organizations need to have in mind. How do you manage their access? What do they have access to? This week we take a look at sponsored guest access with Cisco Identity Services Engine. youtu.be/xJorsH3423E?...

This is your reminder to backup your files.

This week, I use Cisco ISE to apply Posture policies to the devices that join my network. This is a way you can ensure devices are following you org's policies and are compliant. youtu.be/zA8-ogu5iNg?...

Welcome to Monday! Unless you’ve already been there for hours.

Current status:

Figuring out the type of devices that connect to your network is important in the visibility journey. It lets you make decisions on what should or should not be in your environment or what resources they should access. This week, I use Cisco ISE to explore Profiling. youtu.be/8OxT8dXt3kM?...

Timeline cleanse!

Your reminder to make sure <Important thing> is backed up.

It was close to 80 degrees earlier this week. Today it’s snowing. Gotta love this time of the year.

“Your Change Request uses too many big words.”

Five hours of sleep a night…good right?

This week I spend some time in the lab moving from MAB to PEAP using Cisco ISE. There are always good opportunities in the org to tighten up security. youtu.be/EpsrsGF8uUg?... For previous vids: youtube.com/@zerosandwon...

Meeting etiquette: Just because the meeting is an hour long, doesn’t mean you have to use every possible second. It’s ok to give folks time back.
