Don’t Do KRACK: Dealing With WiFi Security Attacks

Not Even Once.

In the last couple months a wireless vulnerability known as KRACK (Key Reinstallation Attack) was discovered. Basically, this exploit takes advantage of how the devices hand off each other’s encryption keys. Most major brands of wireless providers such as like one we use called Ubiquiti were patched within hours if not days. But most of the small businesses that purchase generic routers are unaware and are still being affected.

Understanding Managed Wireless

That is where managed wireless comes into play. With managed wireless your access points, switches, firewalls, routers are all up to date as firmware is pushed out. This makes hacking these type of wireless networks with known exploits very tough. The kind of clients that need this kind of service are hospitals, hospitality, real estate, banking, financial and more. You do not want some guy sitting out on the street with a laptop running a script getting inside your network and manage wireless prevents just that.

Stopping Network Penetration

What we have seen over the last decade are people that take advantage of wireless exploits to penetrate networks. We have blogged about this in the past as a test to get into a clients network, but if our intentions were nefarious we could easily penetrated the network and seized control. With the updates happening regularly, patching done regularly, and watching how the network performs, managed wireless networks can help your business stay secure, give your clients that use Guest services a positive experience and keep you up on the latest trends when it comes to options for wireless technologies.

Worried about KRACK and other WiFi exploits? We recommend for all businesses to get a managed wireless access point. Contact Triton Technologies today to learn more about our wireless access point installations, backed with Managed IT Services.

Network Security: First, Middle and Last

We had the fun privilege this week of doing a security check for a restaurant.

We have agreements with banks, credit card processors and more to analyze a network for security issues or make changes to a client’s network because of a new point of sale system to be installed or modifications to existing ones.

The Restaurant’s Network

It was a simple restaurant, 5 workstations, a router and on-screen credit card swiping.

The meeting was to discuss security, and how to implement it in a manner that doesn’t impact the business. I arrived early with the credit processor and sat down.

Gaining Entry to the Network

Within a minute I had on a Samsung Tablet, logged into his wireless, logged into his router, cataloged his entire network, logged into the music system and started playing “The Pinacolada Song” through the overhead speakers.

With the next two minutes, I logged into the into the point of sale computer, copied the outstanding credit card batches report, locked all the workstations, and had the HP printer print out the lyrics to “I’m a little teapot.”

By the time the manager sat down, the network was in our total control with the ambiance now the melodic sounds of Rupert Holmes which were heard throughout the restaurant.

Complete Takeover: Under 5 Minutes

Total time, 4 minutes. Complete network take over without any advanced tools.

As I explained this in front of his credit processor, I could see the blood leave the face of the manager. And to show I truly did have control, I changed the music to “The girl from Ipanema.”

You could hear their collective jaws drop as they hit the table.

What You Need for Network Security

Over the next hour, we talked about securing the network using Sophos Firewalls, Ubiquiti Wireless Access, and a Cisco switch to VLAN everything together. Proposal accepted in FULL.  

Security is no joke, and it should be the first thing you consider when designing a network. It’s not a burden when it protects what you have, your clients data and can keep your business working especially when the banks can giveth and taketh away your credit card processing ability. Contact us today if you’re interested in knowing how secure your business network is.

Why Restaurants Need WiFi

If your restaurant wants to survive, it needs wifi.

When it comes to selling more restaurants need to attract more clients or high-priced clients. How does a business do that? Business clients, high spenders, people that will spend hour after hour sitting and ordering, not just one thing, but many things.

How does a hospitality facility do that? Good wireless.

Wifi is Now Inexpensive

Wireless has come a long way in the last couple of years and it is extremely inexpensive. Vendors such as our preferred vendor Ubiquiti offers a captive portal for restaurants to also help generate marketing data. For a client to use their wireless, they need to sign up, like or add a page from their website to social media. This helps with mailing lists, mailers, and helps demographic data to be compiled.

In the past, it used to be terribly expensive, but now for easily under $1000 a business can establish powerful access points, gateways, and switches which are all cloud controlled and accessible on any device.

Wifi is Now Secure (When Setup Properly)

How secure is it? Very. Many wireless isolates their clients, and VLANs the traffic making it nearly impossible to snoop and you can have multiple networks on a single managed switch without any extra cost. By isolating it out it makes it PCI compliant allowing the credit card devices to be on the same wire as the wireless network.

As a user who is mobile, I purposely patronage businesses that have wifi and will continue to do so into the distant future.

Why We Recommend Ubiquiti Wireless Access

Wifi isn’t complicated. What is complicated is people.

For a long time, most small business would go out to their local office supply store, purchase a router, create wifi and give it no password so their patrons could access it without an issue. Those days are long gone. Businesses need to scale and the wireless network technology has arrived to allow it.

Good Wifi: A Product and a (Quick) Story

Ubiquiti Wireless Access with Triton Technologies logo.

We recommend a brand called Ubiquiti. Never heard of them? They are the secret for many MSPs and IT consultants. Their technology is simple to install, simple to manage, and easy to deploy.

A prime example is a hotel we did in Massachusetts. Over 90 access points, 6 switches, 2 gateways, 1 load balancer and we got the install done in a day. Literally. All the changes, tweaks and configurations were done within 7 hours with only 30 minutes downtime programming the switches. It was truly a great feat to see.

With their technology it is also cloud based, so any network changes, from their login portal, firmware updates and more are done entirely over a web browser. It is a joy to access and modify the settings.

Why is Wifi Important for a Business Owner?

Wifi brings customers. From hospitals, hotels, restaurants, and more, wifi is an integral part of their business. The longer a client can sit at a restaurant, the more they order, the greater the profit. For motels and hotels, to get the luxurious conference contracts, businesses need to get great wifi and services like Ubiquiti can provide that service quickly with a minimum of fuss.

What makes them so great?

  1. No licensing costs. You bought it, you own it and can operate it until you replace it.
  2. Easy to install. Industry standard design, compact design and easy to install hardware kits.
  3. Cloud manageable. Just log into a single website and access thousands of sites at the click of a mouse.
  4. Low cost. Their access points are easily under a $100 price point.
  5. Accessories. Literally hundreds of easy to access accessory devices such as external mounts, antennas and more.
  6. Simple technology. The interface is clean, no fluff, no ads: just easy to read and understand menus and interface.

With hundreds of deployments, from the single access point or thousands of units throughout Worcester, we recommend the Ubiquiti line of wireless technology.

Let’s help you get it installed at your business.
