Understanding Cyber Essentials' Five Technical Controls

 

 

As CEO of AiMTECH, I’m often asked about the real value behind Cyber Essentials. It’s not just a certification; it’s a fundamental step in protecting your business from the ever-evolving landscape of cyber threats. So, let’s dive deeper into the five technical controls that make up Cyber Essentials, and why they’re essential for your organisation’s security. 

 

Firewalls serve as your first line of defence, acting as a barrier between your trusted internal network and untrusted external networks. By controlling incoming and outgoing traffic, they prevent unauthorised access to your systems. Cyber Essentials mandates that businesses use properly configured firewalls to shield sensitive information from potential intruders. It’s crucial to ensure that all default passwords are changed, and only necessary services are exposed to the internet. 

 

Every device and software application comes with default settings that may not be secure. Cyber Essentials emphasises the importance of secure configuration, which means adjusting settings to minimise vulnerabilities. This includes disabling unnecessary features, managing user privileges carefully, and regularly updating software to prevent attackers from exploiting known weaknesses. 

 

Not everyone in your organisation needs access to everything. User Access Control is about implementing the principle of least privilege, only granting employees the minimum level of access necessary for their roles. By restricting administrative privileges and regularly reviewing access levels, you reduce the risk of insider threats and limit the potential damage from a compromised account. 

 

Malware, such as viruses, ransomware, and spyware, poses a significant risk to businesses. Cyber Essentials requires robust malware protection, which can be achieved through antivirus software, whitelisting approved applications, and implementing sandboxing techniques. These measures help detect and block malicious software before it can cause harm, keeping your data and systems secure. 

 

Outdated software is one of the most common ways cybercriminals gain access to systems. Patch Management is the process of ensuring that software updates and security patches are applied promptly. Cyber Essentials insists on regular patching to address vulnerabilities as soon as they are discovered, reducing the window of opportunity for attackers. 

 

 

These five technical controls are not just boxes to tick, they are essential practices that lay the foundation for a secure IT environment. By implementing them, you protect your business from the most common cyber threats and demonstrate your commitment to safeguarding your clients' and partners' data.
