The 5 Key Controls in Cyber Essentials

In today’s article, I’ll walk you through the 5 key controls laid out by Cyber Essentials, understand what these are, and why these are important to the Cyber Security of your business.

Author: Rob Jervis, CTO at Aristi, has been working closely with the Cyber Essentials Scheme since its inception in 2014 and has supported countless organisations of all sizes with Cyber Security.

To improve your security measures and achieve Cyber Essentials accreditation, it is crucial to understand and implement the five key controls. These controls help to protect your business and ensure compliance with the Cyber Essentials standard. Let's explore these controls in detail:

1. Firewalls

Firewalls are used to protect your business from unauthorised access. Proper implementation of firewalls is critical to adhering to Cyber Essentials and enhancing overall business security. Firewalls protect systems and networks from unauthorised and unexpected connections, which can allow attackers access.

2. Secure Configuration

Secure configuration involves properly setting up your computer networks and devices to reduce vulnerabilities. Mismanaging configurations can lead to significant security issues, making this a vital control for maintaining a secure environment.

3. User Access Control

Restricting access to your data and services is crucial for security. Implementing robust access control measures ensures that only authorised individuals can access sensitive information, protecting your company in the process. Implementing the principle of least privilege ensures everyone has the right access at the right time, and that they are able to work effectively and securely.

4. Malware Protection

Protecting your business from malware is a basic control for maintaining safety and security. Implementing effective malware protection strategies helps safeguard your systems and data from malicious attacks, and unexpected downtime. Combining this control with a solid backup strategy helps protect against the risks of ransomware.

5. Patch Management

Good patch management is an important practice which ensures updates are applied to your devices and software in a timely manner, to protect against newly identified software vulnerabilities. This control is vital for maintaining security and reduces the exposure of your systems to exploits that could compromise your business.

In Summary

Understanding and implementing these five controls will not only help you achieve Cyber Essentials accreditation, it will significantly enhance your organisation's security posture.
