What is 'Zero Trust'?
Zero Trust is a security framework that assumes that every person, device, and application that attempts to access your network is a potential threat.
The goal of Zero Trust is to prevent unauthorised access to sensitive information and systems, even if an attacker has already infiltrated your network.
What Zero Trust Is Not
Zero Trust is not a single technology or product, but rather a holistic approach to security. It’s not a silver bullet for all your security problems and shouldn’t be viewed as a replacement for traditional security measures, like firewalls and antivirus software.
Instead, zero trust should be thought of as an additional layer of security that works in conjunction with other technologies and processes.
Why Zero Trust Is Important
The traditional perimeter-based security approach, which relied on firewalls and other security technologies to protect the network from external threats, is no longer enough in today’s increasingly complex and dynamic threat landscape.
Cyber attacks are becoming more sophisticated, and the rise of remote work and bring-your-own-device (BYOD) policies have made it easier for attackers to gain access to sensitive information.
Zero Trust helps address these challenges by ensuring that every access request is verified and authorised, regardless of where it originates.
Steps to Achieve Zero Trust in Small to Medium Businesses
Identify critical assets and sensitive data. The first step in implementing zero trust is to understand what information and systems need to be protected. This will help you prioritise which areas of your network should be secured first.
Implement multi-factor authentication. Requiring users to provide multiple forms of authentication, such as a password and a fingerprint, will make it more difficult for attackers to gain unauthorised access to your network.
Segment your network. Divide your network into smaller segments, each of which is protected by its own security controls. This will help limit the damage that can be done in the event of a breach.
Use micro-segmentation. Take network segmentation a step further by implementing micro-segmentation. This involves creating smaller, more granular segments within your network to protect sensitive information and systems.
Monitor and respond to security incidents. Regularly monitoring your network for security incidents and having a response plan in place is crucial to maintaining the security of your network. This will help you detect and respond to security incidents quickly, minimising the damage that can be done.
In conclusion, Zero Trust is an essential security framework for small to medium businesses in today’s threat landscape.
By taking the necessary steps to implement Zero Trust, you can protect your critical assets and sensitive information from cyber-attacks and maintain the security of your network.
