Definition
Backhaul is the process of transmitting data from a remote location to a centralized site, like a data centre. It facilitates data transmission between multiple locations, enables network expansion and connects users to remote areas.
However, since backhaul transports sensitive data, organizations must protect backhaul infrastructure to safeguard the transmitted data’s confidentiality, integrity and availability.
Advantages and Disadvantages of Backhaul
Pros
- It creates connectivity between core networks and remote locations.
- Protects unauthorized access by securely transmitting sensitive data.
- Improves efficiency and performance levels due to its scalability.
- Ensures effective communication by reducing downtime and disruptions.
- Wide compatibility with diverse technologies allows for flexibility.
Cons
- It’s expensive to maintain the backhaul infrastructure.
- It might introduce limitations that lead to congestion, high latency and poor performance.
Ways of Protecting Backhaul
- Robust encryption: Encryption protocols protect transmitted data, especially when using wireless technologies.
- Access control: Authorization protocols such as multi-factor authentication (MFA) and role-based access control (RBAC) limit who has access to backhaul infrastructure.
- Network segmentation: Through network segmentation, you can isolate the backhaul network from other infrastructure parts, minimizing the impact of cyber-attacks.
- Intrusion detection and prevention (IDPS): These services monitor network traffic for suspicious activity, allowing you to respond promptly to threats.
- Regular security assessments: Regular checks, such as scanning and penetration tests, ensure early detection and response to potential threats in the backhaul infrastructure.
