Day 19 - Gateway

gateway1.png

In the contexts of Information Technology and of humanity,  I define “gateway” as a portal for change. We, and our data, may enter new environments by passing through that gateway.

When you discover your network communications are limited by what can be reached locally, your options are to give up, or to send your IP traffic out a gateway to other networks.

There’s no guarantee what you’ll find through the portal will be improve your situation, or make it worse. Just understand that the knowledge and risks that come from passing through a gateway are essentially limitless.

I remember a gate that my childhood friends and I climbed through to access a favorite fishing hole. Yes, we were trespassing. And sometimes we were hurt there. But every single trip through that gateway was an adventure. It became a gamble of risking injury or getting caught against the possible payout of big fish (and peer admiration!), or splashing and swimming, or even the opportunity to perform amateur forensic analysis at the site of some impromptu beer party. Past this gateway we sought adrenaline on our path to some future and mystical condition called “adulthood.”

If simply passing through a gateway changes your environment, it becomes a bridge to new opportunities, and as such, may require a guardian to keep out what is unwanted, and to allow you (or your data) pass through. Not unlike the Bifrost Bridge of Norse mythology, recently referenced in Marvel Universe movies.

It has a guardian who sees and knows much—but perhaps not all, and perhaps not enough!

How does your IT environment deal with gateways?

  • Does it limit traffic by source, destination, source port, and destination port?
  • Does it filter content and/or restrict other access?
  • Who has access to the keys to your gateway?
  • Who reviews and inspects the behavior of your staff who hold the keys to the gate, thus ensuring their power is not abused or misused?

Tell us about your own Bifrost Bridge and its Guardians—how you keep them working as needed, how you learn to improve their performance, and how SolarWinds can be a gateway into silos to which you previously had no access!

My first thoughts on the word Gateway and having read the article, is from the 'Gateway to Opportunities' angle. I have always been a great believe in we make our own paths in life. Some by design, some because of outcomes from previous decisions. The pressure on children whilst still at school is to choose their 'Options' (Not sure what this process is called outside of UK), but this is where you choose your focused lessons, whether they be a language, specific science track, IT, history etc., with the purpose that you are receiving teaching on your chosen career path.

Well I am sorry, but at that age I had nothing but a semblance of an idea on what I wanted to do in life (still not 100% sure if I am honest). Myself and many of my friends are working in areas that have little or no relationship to the choices made way back then. My career path has been one of opportunity, but based on decisions and actions that I put in place that opened doors (gateways) to opportunities that have come my way.

A gateway is an open to door to anything.

This remind me of gateway computers, from network perspective you also have gateways and we all need some sort of gateway in life.

I bought a set of speakers from the company Gateway before they shut up shop in Australia. They lasted me a very long time and I was pretty happy with them.

I then delved into networking and starting learning about subnets and network gateways. From a networking background, now one of the first checks with connectivity problems is "can you ping your gateway?"

A gateway is a portal into something new or different, whether in IT or life. It can act as a transition point to allow or deny access, particularly in IT. Ether way it is a sign that a change is about to happen.

A gateway is the opportunity to leave your small LAN behind and enter the vast Internet.

I love the Marvel reference!  No matter how good your gatekeeper is, vigilance is required to monitor any anomalies on the network that indicate unwanted traffic has slipped past the gatekeeper. 

I remember Gateway computers.  I had a lot of success with them back in the late 90's especially when they purchased ALR.   It was a good few years, then, they fell off the map and i have been with Dell ever since. 

Gateway is a door, as stated by, desr​ and i also believe its a opening to an opportunity to knowledge. I think we can utilize our gateways to all sorts of interesting paths.   Chose wisely, someone may be watching...

A Gateway is a moveable barrier in a fence.  Some may contain access controls to only allow authorised visitors.  Some are locked to all and some are wide open.  Hopefully you can stop unwanted visitors and hopefully the fence is high enough to stop unwanted visitors just climbing over.

I'm currently learning to be the keeper of the gateway and all of the above.  I don't have the keys yet, but we do block the most common traffic businesses do not let through.

There is no such thing as a hall pass to a gateway.

hilarious how many of us immediately thought of Gateway Computers

They even had commercials that could have been inspiration for Word-a-Day challenges!

I read this in the morning and came back to it, and I'm not sure what there is to add. Everyone loves a Marvel reference, right? A gateway is in that double-edged role, enabling access for those inside the circle and preventing access from outsiders, with a little help from some other friends... I'm technically in a position to administrate it, but it still limits me, and me peers try and prevent me from accessing it - for good reason, I'm a bit of a 'break-it-and-see' person... But I do have the capacity and, at a push, the responsibility to change it. So simultaneously, I limit it while it limits me.

Yesterday we saw the note on character aspects, and I rather soberly acknowledged that the questions that stood out were the flaws that I disliked the most. I wonder if in a way, we create a gateway of ourselves with our characters to both limit and protect ourselves.

You are responsible for choosing the people who enter the gateway of your life. Be wise in your choice.

A gateway is a portal one must pass to enable one to get to another location. And this is what came to mind:

It is interesting that in common usage, the term gateway has taken on a negative context, especially in regards to addiction. Is marijuana a gateway drug to more dangerous drugs, e-cigarettes to regular cigarettes, video games to other other addictions, etc. The one common factor between all these things is that there is, often, very little, if any, evidence correlating the two behaviors.

"The Gateway to Adventure." That is how I always envisioned the role of the gateway. A gateway serves as a line of delineation between here and "over there" with an opening. The thought of a gateway brings along with it anticipation, excitement, big horizons, new opportunities, and all that.

In the IT realm the gateway is your first step to reaching the outside world. If you can reach your side of the gateway... Good! If you can reach the other side of the gateway... Great!!! Your next hop is adventure!

This is all I keep thinking of when I hear the word gateway..That darn box.

We have deployed firewalls at many of our locations, in addition to our "portal gateway", which use src/dest to filter traffic.  They are our "Gatekeepers", as it were, and have done fairly well.  We also use them to manage our DMZs, which then allows us an added layer of protection by requiring login to, say, a jump server to access anything in the "Zone".  As for who has access, there are a total of three people out of 3,000 that have the "Keys To The Kingdom", as it were, so 1/10th of 1%?  Let's just hope they don't all take a bus together! 😉

As for the "Gateway" comments, yes I remember the "Cow" boxes.  My first "real" job in the industry was in 1992 as an inside sales rep at a computer store, where we sold HP, Packard Bell (there's a blast from the past!), Compaq and Apple.  Since Gateway was only available through the "Gateway Store", I would see more of them come to our service department because, uh, um, well, I'll just trail off that statem....[indistinguishable mumbling]

Gateway an entrance and an exit. A beginning and an end. To some, perhaps life and death. The Roman god Janus, the two faced god, presided over passages seeing all who passed through in either direction. He stood guard at the gates of cities and temples.

zdavid​​ mentions the use as negative, in connotation, when paired with the word drug, but I think it implies it is the the weaker drug that opens the passage way to the harder. The gates do not always open or present themselves to everyone. It is luck of epi-genetics that can push or drag one through that portal. For some the gateway remains open to pass back thru, for those less fortunate other gateways open up and the continue their tragic journey. For the fortunate ones others people can intervene showing them new gateways to a new beginning, finding some other "Gateway to Adventure" as tinmann0715​ mentioned. Which alters their path and presents new portals to walk thru.

To answer the specific questions rschroeder​ posed:

How does your IT environment deal with gateways?

  • Does it limit traffic by source, destination, source port, and destination port?
    • We limit traversal thru our gateways in various ways, physical separation of connectivity, by group membership and role based authorization, by application, and final perhaps be the source, destination, and port.
    • These are done at the perimeter from external to internal, locally on systems, and then globally within our domain by policy
  • Does it filter content and/or restrict other access?
    • Yes we filter content from the application layer down. Where ever is appropriate. It has been a long time coming to this organization, our internal gateways we left wide open. Now because of external pressures we are forces to lock down those passage ways.
  • Who has access to the keys to your gateway?
    • There are roughly eight people who can control the keys to everything. Three of us can in crisis get access to everyone else's keys.
    • Our user community is just starting to struggle with having their keys open only a few select gateways. It is a big cultural shift.
  • Who reviews and inspects the behavior of your staff who hold the keys to the gate, thus ensuring their power is not abused or misused?
    • It takes two of the three to access all the keys.
    • The three of us can access the master key to the domain, but the other two are alerted to that access.
    • We just hired a member dedicated to Security who is setting up the auditing systems. I configured most of the infrastructure to send that new system the data after I built it for him. My staff will configure the rest of the systems to do the same.

When I saw the word "Gateway" I immediately thought of a helicopter ride I once took.  While on an Alaskan cruise my wife and I opted for an excursion that was a helicopter ride up over the glaciers in Alaska.  It was an absolutely amazing experience and I would recommend it to anybody.  While we were flying up through the mountains the pilot came across on the headsets (which you have to wear to hear each other talk) and told us that nature has gateways and that we were about to pass through one of them.  Following that he flew us up between two peaks and as we came out across the other side we could see a massive ice field nestled in a bowl that was formed by the mountains, this was the ice-pack that a bunch of the major Alaskan glaciers flowed from, it was an absolutely amazing sight.

Filter! I guess your words aren't getting through to the....gateway.

When I saw the images he posted of gateway I immediately thought of stargate and gateway computers as well, but I also think of how an API is a bit of a gateway to the unknown, much in the stargate model. I mean, it is what you make of it, and what's on the other side (of the API) is only limited by what you want to get out of it.

My parents getting a Commodore 64 was my gateway drug into IT. I can pretty much pinoint that as when my interest in all things technology started. It grew when I got a Super Nintendo, then an 386 PC, and just keep going from there. I was always ripping into our old dead electronics to see what they looked like and see if I could figure out how they worked and possibly even fix them.

Fast forward to me (allegedly) being an adult, and I now run the entire network for a hospital and am responsible for making sure it stays in working order. I also just recently got my hands on the Super Nintendo Classic, so I have been putting that through a workout. I build my own gaming pc's completely custom from the ground up. I also even play around with doing some experiments on my raspberry pi 2 that I won here on thwack a few years ago. And it all started with a Commodore 64 and a 5 1/4" floppy.

This is the first thing that came to my mind too!  The old Gateway computer boxes with the cow prints.  What a great company.  Too bad they were bought by Acer.

My first Windows PC was a Gateway 2000 P5-133XL from 1995 that looked like this. That box was a beast. It handled two motherboard upgrades before I decided to get an aftermarket case. It was last running a K6-2 450MHz.

A gateway is often intended to be one way, but generally there is an exchange in both directions. Of course, in an IT discussion there is data exchange. But in life we have many gateways - the phone is a gateway of communications, our homes are gateways of family interaction, our communities are gateways of interaction, supplies and support, TV and media are gateways of ideas. Care must be taken that the gateways to which we subject ourselves build who we are an not negatively impact our lives.

The original "gateways" I remember using were for converting traffic from token ring to ethernet and vice versa.  It was a pretty big deal back in the 90's.
