Normally when you implement IT security for your office network, you create what’s called a “castle-and-moat” setup in which a perimeter (the moat) surrounds your network data (the castle). But these traditional cybersecurity systems can be bypassed by security holes in devices, routers, configurations, missing patches/updates/antivirus, or phishing scams – and cloud apps are often outside your perimeter.
All of these vulnerabilities can potentially grant a cybercriminal access to your business data – but, luckily, there’s now a better way to protect your data. It’s called Zero Trust.
“Castle-and-moat” is a traditional cybersecurity method, which you probably currently use. It works on the assumption that anyone in your network is trusted to access any of the data within your network. In Zero Trust networks, there is no trusted access, which means anytime anyone wants to access secure data, they must prove that they’re allowed to do so.
In practical terms, this means that Zero Trust requires regular authentication on the device level, the network level, or the user level. Authentication takes a little bit of extra effort from the person wanting to access the data but it’s not much extra work. Like using a key to open your front door, a Zero Trust network requires you to have the key (e.g. password, keycard, thumbprint, code) available to unlock that door.
For the user (your employee), it’s a tiny extra step that keeps your data secure. For you, it comes with a ton of benefits: oversight into who is accessing your data and when, as well as control over what people are allowed to do with your data.
Here’s a quick overview of how Zero Trust networks operate. If you’re interested in more of the nitty gritty details behind the Zero Trust setup, check out Part 2 of this series so you can dive into Zero Trust architecture.
It works like this:
As we said, we’ll talk more about this in the next blog in this series, for those of you who want to get really in depth with Zero Trust but, in essence, you can think of Zero Trust as a process of protecting the data, versus the older security methods of simply protecting the perimeter.
In addition to the benefits we listed earlier, Zero Trust methodologies for protecting your data and networks also:
Your WFH employees may have dozens of IoT devices in their homes (including Alexas, smart watches, WiFi-powered vacuums, and smart light bulbs), but consumer IoT devices often have terrible built-in security.
Castle-and-moat security methods made sense in the past, when networks were solely accessed from work computers in a workplace on a local area network (i.e. behind the moat).
In our modern world of anywhere/anytime remote and cloud-based access, that kind of thinking just doesn’t work anymore.
And when those events happen, the unauthorized people or cybercriminals accessing your business networks may not have been legitimately allowed past your “moat.” They’re like spies in your castle.
The best way to stop cybercriminals from seeing your data is to block them out.
And the best way to do that is to set up a Zero Trust network that fits your exact needs.
