Firewalls are a necessary component in any network environment, especially in an enterprise. Take a look at your front door, would you remove it permanently? Firewalls have evolved over the years from simple gatekeepers to complex security solutions that integrate with the rest of the network. Imagine if you could program your front door to only allow people in who wore green shirts. Once inside they would only be able to walk into the living room…on a Tuesday. My own firewall journey started years back on Juniper SSG350s then onto ASA and Palo Alto. I am currently looking into Cisco’s Firepower Threat Defense (FTD). As a fan of most things Cisco (ASA CX anyone?), FTD adds visibility to the rest of the ecosystem that might include AMP, ISE and Stealthwatch. With an ASA 5512-X in hand, my mission is to replace its ASA image with FTD. Continue reading Image Swap: ASA to FTD
Has anyone ever been excited to go to a job they hate? Perhaps on the day they were quitting. No matter what your profession, passion determines how deep into your job or career you will go. If you lack the willingness to learn and the willingness to love what you do for a living, there is no passion. If you find yourself with that lack of passion, what you are currently doing might not be for you. No matter what that job is right now, do it to the best of your abilities. Even if what you are doing is not what you envisioned for yourself. What you are doing might not even have been on your personal roadmap. The goal is to someday look around and find yourself in love with what you do. It does not matter if you accomplish that goal at 20 or 60 years old. I want to write to motivate those working in IT that have not yet found their passion or to those who are interested in the realm of networks. I am a Network Engineer and I love what I do.

Building a network for a new site from the ground up is great experience for engineers and administrators. However, if you are not organized it can also be a nightmare. Companies all over the world handle the “New Site” process differently. The way you maneuver through the project depends on the size of the organization as well as the teams involved. Some places have a complete Project Management Org that will take your project, organize it, shine it up and help you complete it. Project Managers can be a big help by following up with vendors, partners and making sure the teams are meeting deadlines among other things. However, sometimes you might not have a team of PMs helping you. You might be the PM for your particular “New Site” project. Whether or not you are the one doing everything or just the racking of equipment the following items or milestones are just reminders of tasks to keep in mind. Continue reading New Location, Who Dis?
Well, it has not been the start of the year we were thinking of when we made our resolutions last year. The year is almost 4 months in and it feels like we are crawling a decade a week. I pray for those out there affected by COVID-19. Many out there are sick, lost jobs or have family that are sick or have passed. You will get through this. We will all get through this. Daybreak will come.
I wanted to write a little about my experience working from home. I have a ton of technical topics in my head I want to dump in the blog, but all the happenings in the world have pushed me in a slightly different direction. For now, I just want to have a “chat” and try to motivate others.
My company transitioned office employees to work from home a few weeks back and I’ve been here ever since. I normally work from home once a week. Even at my last place, I worked from home once a week. I usually spend about an hour driving in to work and another back. I never hit traffic to and from work since I stay off the main e-ways and try to stick to the back roads. So the hour is usually all driving and a couple of red lights. As someone who supports the world-wide network for the company, I can do my job from anywhere. I’ve always wanted to work from home full-time. Now…not so much. Continue reading From Home I Work
Have you ever read a biography or saw a movie about someone’s life? There are many of them out there. It seems like every month there is a “Based on a True Story…” flick that gets released. It does not matter if the person was an athlete, a politician or even an astronaut; one thing that you will never read or hear them say is “That was the easiest thing I’ve done”. Never. Their accomplishments were hard earned. Blood, sweat and tears went into reaching another level. I would say the same applies to those of us working in the field configuring switch ports , looking over security logs and even providing phone support. No, I am not comparing surviving a war or landing on the moon to someone closing out a “My Netflix does not work in the office” ticket, but a similar mentality is needed. The mentality and actions of someone who wants to reach a higher level professionally needs to mirror those that meet challenges head on or even better: Someone who constantly looks for those challenges. Our professional lives need to be like a treadmill on a constant incline. Many times when our lives level out, we get complacent and speaking for myself, lazy. Look for a challenge and climb! Continue reading Challenge Accepted
Can you give me a list of all the destinations employees at your company are browsing to on the internet in the office and out? Would you know if all of those sites are safe? Are they clicking on those “Free Tablet Just For You!!!!!!” email links? The internet can be a dangerous place. DNS helps users easily reach destinations. Who is going to remember the IP addresses to hundreds of sites? However, DNS can lead users to malicious destinations as well. You might have a need to protect users or enforce company policies at the DNS level.
This post will be a review of Cisco Umbrella. We’ve been using it in production. This will by no means serve as deployment instructions. Please refer to Cisco Umbrella’s documentation for those. These are just my thoughts on how the process went. Continue reading Do it Live: Cisco Umbrella
So you are interested in networking? I don’t mean attending gatherings, handing out business cards, shaking hands and kissing babies. I mean being a network engineer or administrator? Perhaps you just started the journey at a company and feel slightly lost. If you are, then the following paragraphs are meant for you. This is not only meant to be a motivator to continue learning and applying, but here you will find three things to look for or try to work on that can push you upwards in the work place.
Whether you are part of a small team, large team or riding solo there is much more to network engineering. Sure, there are days where it seems like everyone needs a port configured, but there will be times where you can bring forth your ideas into fruition. There will be times where you look around and figure out ways to improve existing infrastructure. You might be interested in pursuing certain software that can improve a process or provide valid insight. You might want to create or update documentation. You might just want to improve certain aspects of a network, such as routing or security. These are all good things to do, time-permitting and team-willing. If you have good ideas bring them up to your team or your manager. This will not only be a good way to learn, but you can excel career-wise by getting involved and pursuing ways to improve your company. Continue reading Beyond Engineering
Have you ever had a work-related dream that you’ve woken up from and were thankful it was just a dream? Designing and executing the network for a new data center will definitely give you a few night terrors. I recall the night before our data center move, I dreamed that I woke up late on the day of the move. That’s not too bad right? Well for some reason, in my dream the data center was in another state instead of an hour away. Then my car did not start; I had to “borrow” a car and I got lost on the way there. Again, I was thankful it was a dream. The actual move went a bit smoother. However, these types of projects can be real nightmares for teams. The main thing to do is plan. You the follow this with a few healthy doses of additional planning. Continue reading Data Center Move: A Perspective
