Edge security is a targeted approach to safeguarding the entry and exit points of a network, specifically where data traffic traverses the boundary between an organisation’s internal network and external networks like the internet. It revolves around the implementation of security measures strategically positioned at the network edge. The network edge forms the boundary between the internal infrastructure and external networks, and becomes the focal point for deploying crucial security mechanisms.

Edge security is a proactive strategy that involves measures such as firewalls, intrusion detection, and prevention systems, designed to monitor, filter, and regulate incoming and outgoing traffic. This comprehensive approach ensures that only authorised users and devices gain access, creating a robust defence against cyber threats.

What are the key elements of Edge Security?

Perimeter Defence

Edge security involves deploying firewalls, intrusion detection and prevention systems, and other security mechanisms at the network perimeter. These tools monitor and filter incoming and outgoing traffic to prevent unauthorised access, attacks, or data breaches.

Access Control

Controlling access to the network is critical for security. Edge security solutions often include access control measures, such as secure authentication methods, to ensure that only authorised users and devices can access the network.

Content Filtering

Edge security may involve content filtering to block malicious content, websites, or harmful applications. This helps prevent users within the network from accessing potentially dangerous or inappropriate content.

DDoS Protection

Distributed Denial of Service (DDoS) attacks can overwhelm a network with traffic, causing disruptions. Edge security solutions often include DDoS protection mechanisms to mitigate the impact of such attacks.

Secure Gateways

Secure gateways at the network edge enable secure communication between internal and external networks. Virtual Private Networks (VPNs) and secure web gateways are examples of technologies used to establish secure connections.

Threat Intelligence

Edge security relies on threat intelligence to stay updated on the latest cyber security threats and vulnerabilities. This helps in the proactive identification and mitigation of potential risks.

Cloud Security

As businesses increasingly adopt cloud services, edge security extends to the cloud edge. Protecting data and applications in the cloud is an integral part of an effective and robust edge security strategy.

Mobile Device Security

With the proliferation of mobile devices, edge security encompasses measures to secure mobile endpoints. Mobile Device Management (MDM) and Mobile Threat Defence (MTD) solutions are part of this approach.
