Edge security definition
Edge security is the practice of protecting data, applications, and devices at the “edge” of the network rather than at a centralized point like a data center. With the rapid growth of the Internet of Things (IoT) and the continued decentralization of IT environments, the edge of networks — where users and devices connect — has become a crucial point to secure.
Examples of edge security
- IoT devices. With billions of devices connected to the internet, from smart thermostats to industrial sensors, malicious actors have gained multiple potential entry points. Ensuring these devices are secure and can securely communicate with other devices and central networks is a primary concern of edge security.
- Decentralized data processing. As more data processing tasks move to the edge (e.g., in edge computing scenarios where data is processed locally on the device or in a nearby gateway rather than being sent back to a central server), there's a need to secure this data, and the processes that handle it.
- Bandwidth considerations. Edge security solutions help reduce the bandwidth requirements of a network. Instead of sending all traffic (including potential threats) to a central location for analysis, only relevant traffic needs to be sent, while potential threats are dealt with at the edge.
- Edge firewalls and gateways. These solutions protect against threats right at the network perimeter or even beyond.
- Physical security. Edge devices can be spread out and located in various places. You should ensure they're physically secure to prevent tampering or unauthorized access.
