Edge Security
What is Edge Security?
Edge security is a type of enterprise security infrastructure that is decentralized, and no longer located in a conventional datacenter. Rather than being centrally located or cloud-based, it functions at the “edge” of an organization’s network computing.
How does edge security work?
Edge security is the process of securing the network at the edge, or rather at the place where the end user is both creating and storing data in a larger network. This form of perimeter security is critical in edge compute environments.
What are the benefits of edge security?
The benefit of edge security is that the protection is often on-device and therefore doesn’t require the full power of the larger network security protocols. This reduces possible points of failure or attack from malicious parties.
What are the challenges with edge security?
The challenges associated with edge security are:
· Decentralized security and increased perimeter defense risks, which can expose the larger data center to vulnerability.
· Password and local security risks where there is no IT professional as a safety mechanism.
· Physical hardware risks, where entire drives or data sets can be physically accessed or infiltrated.
How does edge security work with the Internet of Things (IoT)?
IoT devices pose particular difficulty for edge security for several reasons. The first of these is the sheer number of IoT devices, many of which are consumer-grade and therefore not designed with robust security in mind. These devices often have shorter lifecycles and are developed by companies that are concerned more with adoption rates, useability, and user experience than with edge-based security protocols.
Additionally, many of the devices disallow users from performing software updates, which are essential to security patches when threats are exposed or detected.
Two cutting-edge ideas that show promise are artificial intelligence (AI) threat detection and peer-to-peer (PtP) updating.
Using machine learning and AI, one could detect anomalies in behavior to identify, mitigate, and neutralize risks. When certain network or sensor data triggers a real-time alert, it would reduce the risk of unseen threats.
PtP networks could be used to share firmware updates between users, creating a more robust and secure network of IoT devices that could be patched with current security updates based on known threats to the device network.

Now more than ever, you need to move fast and adapt quickly to change. HPE GreenLake brings the cloud experience to apps and data everywhere, enabling you to adopt transformative technology faster and simplify your operations. HPE GreenLake delivers public cloud services and infrastructure as a service for your workloads—on-premises, fully managed in a pay-per-use model at the edge, in colocations, and in your data center.
HPE has solutions to help ensure that your dynamically adjusting edge is continuously secure—wherever, whenever, and whatever it is. To create a more intelligent edge, you need the following three components:
· You need IoT solutions that can leverage data gathered from “things” on the edge to solve business problems.
· You need networks that can connect the IoT solutions to the rest of the organization in a secure and efficient way.
· And finally, once you have the IoT solutions and the networks in place, you need to take all this and create a digital workplace that defines how your employees and customers engage and conduct business.
