Network segmentation – Understanding Network and Security for Near-Edge Computing

Implement network segmentation to isolate and protect critical edge computing resources. Use Virtual LANs (VLANs) or Software-Defined Networking (SDN) techniques to create separate network segments for different types of devices and services. This helps contain potential security breaches and limit the lateral movement of threats within the network.

Monitoring and logging

Implement comprehensive monitoring and logging mechanisms to detect and respond to security incidents in real time. Monitor network traffic, device logs, and system events to identify any suspicious activities or anomalies. Employ centralized logging and analysis tools to gain visibility into edge computing resources and enable proactive threat detection and incident response.

Security updates and vulnerability management

Stay updated with security patches and firmware updates for edge devices and gateways. Regularly scan for vulnerabilities and implement a robust vulnerability management process to address any identified weaknesses promptly. Consider using automated tools for vulnerability scanning and patch management.

Physical security

Ensure the physical security of edge computing resources. Protect devices from unauthorized access, theft, or tampering by implementing appropriate physical security controls. This may include secure cabinets, access control systems, surveillance cameras, and other physical security measures.

Incident response and disaster recovery

Develop an incident response plan and disaster recovery strategy that’s specific to edge computing environments. Define procedures for responding to security incidents, including containment, investigation, and recovery. Regularly test the effectiveness of the plan and conduct drills to ensure preparedness.

Training and awareness

Provide security training and awareness programs for personnel involved in managing edge computing resources. Educate employees about best security practices, social engineering threats, and the importance of following security policies. Promote a culture of security awareness throughout the organization.

By implementing these security measures, organizations can enhance the protection of their edge computing resources and mitigate potential risks. It is essential to continually evaluate and update security measures to stay ahead of evolving threats and ensure the ongoing security of edge computing environments.

Summary

In this chapter, we surveyed common pitfalls associated with the network and security facets of near-edge computing solutions. This included challenges faced on the internet due to latency, packet loss, and server and client configurations, as well as common protocols in use.

We also covered standard industry approaches to mitigating these issues. We explored how GSLB and IP Anycast are used to reduce the latency introduced by the physical distance between the server and the client. Then, we reviewed HTTP/3 and QUIC – a new set of protocols that eliminates the need to worry about many of the challenges faced by older, more widely adopted protocols such as HTTP/1.1 and HTTP/2.

Lastly, we covered some of the key considerations you must take into account regarding security when implementing an edge computing solution that is not fully based in the cloud.

In the next chapter, we will dive into the same sorts of details for solutions deployed at the far edge.
