Zero Trust & Cybersecurity: Everything You Need to Know

Zero-trust is an increasingly popular approach in cybersecurity. Find out what it is, why it’s so important, and how to implement it in your organisation in the post below.

1. What Is Zero-Trust?

Is there a trust in a cybersecurity approach that is based on the idea that everyone who uses your system must be verified every time? In other words, a zero-trust system is the opposite of a network that has implicit Trust.

It’s based on the idea that there is almost a constant level of threat from both outside and inside your own network, and is designed to mitigate this. It does this by using authentication and authorisation methods that are continuous and active for every user and every session.

Combined with the use of segmented security zones, the zero-trust approach means those that have not got the proper security permissions will not be able to access your network. Additionally, these approaches are further affected by restricting user access only to the information and tools that are necessary.

2. Why Is The Zero-Trust Approach Important In Cyber Security?

Zero-trust approaches inside security are important because of the rapidly evolving nature of cybersecurity threats. Indeed, because threats are being specifically designed to get around more traditional cybersecurity defences, instituting the zero-trust approach can significantly increase the security of your system and decrease the chances of a data breach.

In turn, this should help your business be much more compliant with regulations such as GDPR, making it more trustworthy and reducing the risk of expensive fines or ransomware attacks.

3. Instituting a Zero-Trust Approach: Learn From The Experts

Now you know more about what a zero-trust approach is, and why it’s so important for your organization it’s time to look at how you can institute one. The first stage of this is to learn as much as you can from the experts, not only about zero-trust approaches but also about the types of cybersecurity threats that are an issue right now.

By better understanding the threats that your organisation is facing, you will be able to better respond and protect against these. Understanding not only what needs to be done to protect your network, but why, something that can help you avoid gaps in your approach.

The good news is that there are many places you can go to get high-level expert advice on this, including cybersecurity blogs written by experts online. Indeed, you can greatly increase your chances of avoiding issues such as online scams and attacks by reading what the experts have to say on the subject.

The best ones even offer products and tools that will help you boost your cybersecurity provision, too.

4. Instituting a Zero-Trust Approach: Technical Implementation

One aspect of instituting a zero-trust approach that you must deal with is the technical implementation side. Now this can be quite complicated, especially for those who are not on your technical team. However, the bare bones put simply are that you will need to :

• Use multifactor authentication for all users

Also known as 2FA or two-factor authentication, multifactor authentication is where at least two verification methods are used to log a user into a system or network. That means instead of just using a password, a user needs to also enter a code generated or sent to a separate device.

The main benefit of this is that it can massively reduce the risk of automated attacks, because the user has to have access to the second device or method in order to gain entry.

• Use micro segmentation

Segmentation is all about isolating different zones from each other. Think of them as islands that only individual users can access. In this way, security breaches from island to island are reduced because it’s impossible for users to move between the islands. Instead, they can only access their own.

• Complete regular device health checks

Each device is like a window into your network or system. It’s important to check that each of these windows is secure, it could let in uninvited guests. The best way to do this is with regular device health checks. Be sure to monitor software updates, update operating systems, clear caches, and run diagnostic tools.

• Use continuous monitoring systems

Imagine being able to see exactly what each user is doing, the health of their device, and current network traffic, all in real time. Well, that is exactly what continuous monitoring allows you to do, and with it, you can further enhance your zero-trust approach.

• Swap to zero-trust for network access

This is all about switching from castle and moat security measures to protect your network to identity-based security measures. It’s a system that automatically trusts no one as they log in. Instead, they require that they verify their identity sufficiently before they are allowed access.

5. Instituting a Zero-Trust Approach: Moving Forward With A Zero-Trust Approach

To implement a successful zero-trust approach in your organisation, you will need to properly plan and prepare. This can often mean starting small and running pilot zero-trust projects in limited areas of your organization. In this way, you can test out how this approach will work best for your specific needs, and show the rest of the company the value and how easy it is to use.

Usually, it’s best to start with areas where the most sensitive data or systems are stored. Then you can best utilise the benefits of zero-trust to protect your most valuable assets. It’s also crucial that you not only implement these changes but also train staff on how to use them. This will reduce a great deal of friction and user error as you roll them out.

Lastly, do not forget that, like every invocation you institute in your organisation, you will need to properly monitor its efficacy and use. That means tracking any incidents, access request and response times, and adjusting as necessary.
