Understanding the Five Key Areas of Cyber Essentials

Small to medium sized business form the backbone of the UK economy, yet they often operate with less the sufficient cyber defences in place. This is often due to a lack of technical knowledge or experience, or even following the common misconception that cyber security is unreachable for smaller teams and businesses. To help support these businesses, and to boost the overall resilience of the digital economy, the UK Government created the Cyber Essentials certification, a government-backed initiative designed to help businesses safeguard themselves against the most common cyber threats. This article will explore the five key areas of Cyber Essentials that every business should focus on to enhance their cyber security posture, and to help them comply with Cyber Essentials.

1. Firewalls: Building a Secure Barrier

Firewalls act as the first line of defense for your network. They monitor and control incoming and outgoing network traffic based on predetermined security rules. By implementing properly configured firewalls, business can block unauthorised access to their network and data, while still allowing legitimate traffic through.

Key Actions:

Ensure that firewalls are installed on all devices connected to the internet.

Regularly update firewall rules to adapt to new threats.

2. Secure Configuration: Making Devices Cyber-Safe

Secure configuration involves adjusting the settings on your devices and software to minimise vulnerabilities. This includes disabling unnecessary features, removing outdated or unsupported applications, and changing default passwords. A properly configured device reduces the risk of unauthorised access and helps protect sensitive data.

Key Actions:

Regularly review device settings and configurations.

Remove any software or services that are not in use, or are no longer updated by the provider.

3. User Access Control: Restricting Access Based on Need

User access control focuses on ensuring that employees only have access to the information necessary for their roles. This principle, known as least privilege, helps reduce the risk of data breach as it prevents unauthorised individuals from being unnecessarily exposed to sensitive information. Implementing strong password policies and multi-factor authentication can also further enhance security.

Key Actions:

Limit user permissions based on job requirements, with stringent access requirements on sensitive or private data.

Enforce strong password policies and use multi-factor authentication.

4. Malware Protection: Defending Against Malicious Software

Malware protection is essential for detecting and removing harmful software that can compromise your systems. This includes viruses, worms, trojans, and spyware. Businesses should install reliable anti-malware solutions and ensure they are regularly updated and configured to defend against the latest threats.

Key Actions:

Use reputable anti-malware software across all devices.

Schedule regular scans and updates to maintain protection.

5. Security Update Management: Staying Ahead of Threats

As mentioned previously, regularly updating software and systems is critical for protecting against known vulnerabilities, as cyber attacks often exploit outdated software to gain access to systems. Automating updates can help ensure that no critical patches are missed, keeping your systems secure.

Key Actions:

Set up automatic updates for all software and operating systems.

Regularly check for updates on applications that do not support automatic updates.

Conclusion: Strengthening Your Cybersecurity Posture

Achieving Cyber Essentials certification is a significant step towards enhancing the cyber security posture of a business. By focusing on the five key areas of firewalls, secure configuration, user access control, malware protection, and security update management, you can build a robust defense against cyber threats.

Furthermore, utilising compliance software like OneClickComply can automate the process of implementing and monitoring these controls, ensuring that your business remains compliant and secure in an ever-changing digital landscape.
