When it comes to IT security, zero trust security means that you take nothing for granted. Every user, device, and application will be authorised for every access request, no matter who, what, or where they are.
In this post we’ll outline how a zero trust security framework operates in practice, and explore whether zero trust security is the best system for SMEs.
What is Zero Trust Security?
The zero trust security framework means that nothing in an organisation’s network can be trusted by default. Instead, every user, device, and service must be continuously authenticated, authorised, and validated any time they try to access any service or resource.
In a zero trust cybersecurity system, users can only gain access to services and resources when it’s strictly necessary, and they’ll be closely monitored throughout the process.
Limitations of Traditional Security Systems
Traditional cybersecurity systems operate like a castle with a moat. The moat and the castle’s walls are effective at staving off most attacks. But what about attacks that come from within the castle itself?
A zero trust security system eliminates some common cybersecurity threats through eliminating “inherent trust”. For example, the CEO or head of IT may be trusted to access whatever systems they want, whenever they want. Plus, employees may remain logged into certain systems round the clock, for the sake of convenience.
But cybercriminals can exploit this. If they steal certain credentials or gain access to certain devices, they could access your most secure systems.
The Benefits of Zero Trust Security
Zero trust security systems operate less like a castle with a moat, and more like an airport. As you move through an airport, you must prove your identity and pass through security systems whenever you want to access a new area. Plus, you’ll only ever be allowed to access one specific aircraft, and if your name’s on a no-fly list, then you’ll get no access at all.
The point is that these checks apply to everyone, all the time, with no exceptions. Plus, rather than a single authentication at a single point of entry, there are strict controls throughout the system.
Does Your SME Need a Zero Trust System?
All businesses need to take cybersecurity seriously. But SMEs may be particularly vulnerable to cyberattacks.
According to one study, 96% of all cyberattacks are directed at SMEs. A separate study suggested that cybercriminals are around three times more likely to target smaller businesses over larger businesses.
Why? Simply because they know that SMEs are less likely to have sophisticated cybersecurity systems in place, or the means to respond effectively to data breaches. And with the rise of AI systems, cybercriminals are now more powerful than ever.
A zero trust framework could help you secure your systems against all possible threats. But this is not the sort of system you can simply implement overnight. It’s an ongoing commitment that may require significant changes to how you build and manage your digital systems.
How To Implement a Zero Trust System For Your SME
A zero trust system isn’t a product you can buy. Nor is it the sort of thing that you can just turn a key to activate. It’s best to think of it as a strategy, as a collection of security procedures that work together.
To implement zero trust for your SME, you will need to:
- Fully understand your digital systems, along with all risks and vulnerabilities
- Design the right security controls that work for your system, your staff, and your devices
- Define your priorities, and assess how you’ll measure your impact
You may need the assistance of a specialist IT consultant to help you design and implement a zero trust security framework for your business. The Government’s National Cyber Security Centre could also offer some support.
