Zero Trust Security: How Does It Work and Who Needs It?
Gone are the days when employees worked from just one location, supported by a local IT infrastructure. Today, remote work arrangements are common and highly sought-after. The traditional network perimeter doesn’t exist anymore. That’s because employees now rely on a combination of work and personal devices to access a growing number of cloud services.
This new IT environment has made traditional approaches to cybersecurity ineffective. Thus, leading to an explosion of data breaches, ransomware attacks, and other costly incidents. Fortunately, a more robust approach to cybersecurity already exists, and it’s called zero trust security. Let’s take a closer look at how it works and who should implement it.
What Is Zero Trust Security?
As the name implies, zero trust security is a security model that doesn’t trust any user, device, or application by default, regardless of whether they’re located within the main network or outside.
Don’t be surprised if this model seems familiar to you. It was actually first presented by an analyst at Forrester Research Inc. in 2010. While many large enterprises have been relying on it for a long time, most SMBs were perfectly content with the castle-and-moat approach to security.
In the castle-and-moat approach, everything inside the network (= the castle) is trusted, and only outside connections are verified by a firewall or other security tools (= the moat). As you can imagine, this approach stops working when employees are forced to leave their offices. Why? Because of a global pandemic, or when organizations embrace the cloud to increase their efficiency and lower their costs.
As soon as an intruder gets over the moat, they can do whatever they please inside the castle. That’s unacceptable!
By always authenticating and authorizing all users, devices, and applications (even if they already reside inside the castle), zero trust security prevents a single intrusion from having disastrous consequences. Essentially, it ensures that all doors inside the castle are safely locked at all times and impossible to open by force.
When a remote employee working for an organization that has adopted the zero trust security model becomes compromised, the impact is highly localized because the threat is unable to move laterally across the network and keep spreading. The same happens when a third-party cloud vendor becomes infected with malware, or when one employee’s personal mobile device has spyware installed on it.
What Are the Main Benefits?
According to a recently published report, the global market size of zero trust security is expected reach $51.6 billion by 2026 from $19.6 billion in 2020, growing at a CAGR of 17.4 percent.
Clearly, many organizations see it as the best way forward. However, improved security posture isn’t the only benefit they’re attracted by. Here are three other important benefits that you should know about:
How to Achieve Zero Trust Security?
Zero trust security is a holistic security model, so it doesn’t depend on any specific technology. There are, however, certain principles that all zero trust security implementations must follow:
Since there are countless different ways to achieve zero trust security, it’s paramount that you select the approach that best meets your needs and requirements.
