What are the Five Controls of Cyber Essentials?
Introduction to Cyber Essentials
In today's digital landscape, cyber threats are more prevalent than ever, posing significant risks to businesses of all sizes. Cyber Essentials is a UK government-backed scheme designed to help organisations protect themselves against a range of the most common cyber-attacks. Achieving Cyber Essentials certification demonstrates that a business has taken essential steps to safeguard its data, systems, and networks from cyber threats.
At its core, Cyber Essentials focuses on five fundamental technical controls that, when implemented correctly, can defend against various cyber-attacks. These controls are crucial for any organisation aiming to establish a solid foundation for their cybersecurity posture.
1. Firewalls
Firewalls act as the first line of defence between your internal network and external threats. They monitor and control incoming and outgoing network traffic based on predetermined security rules. A properly configured firewall can prevent unauthorised access to your network, effectively blocking potential cyber-attacks.
Key Points:
- Network Segmentation: Firewalls can segment your network, limiting the spread of malware or unauthorised access within your organisation.
- Access Control: By setting rules for inbound and outbound traffic, you can ensure that only legitimate traffic is allowed, reducing the risk of cyber threats.
- Monitoring and Logging: Firewalls provide network activity logs, which can be crucial for identifying and responding to suspicious activities.
2. Secure Configuration
Secure configuration involves setting up systems and devices securely, reducing the risk of vulnerabilities that could be exploited by attackers. This includes removing or disabling unnecessary functions, accounts, and services that could be potential entry points for cyber criminals.
Key Points:
- Default Settings: Changing default passwords and settings to more secure options is essential to prevent unauthorised access.
- Software Updates: Regularly updating software to the latest versions ensures that known vulnerabilities are patched.
- Minimal Services: Disabling unneeded services and accounts reduces the attack surface, making it harder for attackers to find weak points.
3. User Access Control
Controlling who has access to your data and systems is critical to maintaining security. User access control ensures that only authorised individuals have access to sensitive information and that their access rights are limited to what is necessary for their role.
Key Points:
- Least Privilege Principle: Granting users the minimum level of access required to perform their duties helps to limit potential damage from compromised accounts.
- User Authentication: Implementing strong authentication methods, such as multi-factor authentication (MFA), enhances security by requiring additional verification steps.
- Regular Review: Periodically reviewing user access rights ensures that only current employees and necessary accounts retain access, removing unnecessary or outdated permissions.
4. Malware Protection
Malware protection involves implementing measures to protect against malicious software that can infiltrate, damage, or steal data from your systems. This includes using anti-virus software, anti-malware tools, and other protective technologies.
Key Points:
- Anti-Virus Software: Installing and regularly updating anti-virus software helps detect and remove malicious software before it can cause harm.
- Web Filtering: Blocking access to known malicious websites reduces the risk of malware infections from online sources.
- Email Filtering: Filtering emails for spam and malicious attachments can prevent malware from being delivered via phishing attacks.
5. Patch Management
Patch management is the process of regularly updating software and systems to fix vulnerabilities and improve security. By keeping your software up to date, you can protect against known threats and ensure your systems are running securely.
Key Points:
- Automated Updates: Using automated update tools ensures that critical patches are applied promptly, reducing the window of vulnerability.
- Regular Scheduling: Establishing a regular patching schedule helps maintain consistent protection across all systems and applications.
- Testing Patches: Testing patches in a controlled environment before deployment ensures that they do not introduce new issues or conflicts.

Implementing the five controls of Cyber Essentials is a fundamental step in protecting your organisation from the most common cyber threats.
