Solution for Network Security Improvement for a Rural Commercial Bank

Client Background:

Since its establishment, a rural commercial bank has maintained a traditional network system, utilizing a three-layer network architecture pattern composed of numerous layer 2 switches and a few layer 3 switches. While this hierarchical network model offers advantages in stability and redundancy, it no longer meets the bank's expanding scale and business volume.

Importance of Network Upgrade:

Support Business Innovation:

Upgrading the network of the rural commercial bank can provide more advanced technological support, laying a solid foundation for business innovation and enhancing customer trust and satisfaction.

Enhance Customer Experience:

Network upgrades for the rural commercial bank can improve the stability and response speed of the banking system, enhancing the customer experience.

Enhance Security:

Updating network equipment and security protection systems ensures the security of internal systems and customer data, preventing various network attacks and fraudulent activities.

Adapt to Digital System Development:

With the development of digital systems, there is an increasing demand from customers for online business transactions. Network upgrades enable banks to better adapt to the trend of digital development and enhance competitiveness.

Challenges:

High Throughput:

As a location with high business volume, the bank's network requires high throughput and strong device performance to ensure normal operation under high loads.

High Scalability:

The bank's network architecture needs to continuously expand and improve according to business needs, requiring enterprise network equipment with high scalability to meet the demand for additional devices due to business expansion.

High Security and Reliability:

Due to the special nature of banking systems, network security is a key focus of network upgrades. Enterprise information security is related to the overall operation of the enterprise, with severe consequences potentially affecting the survival of the enterprise and its customers. Therefore, network upgrades must strictly control network security systems.

Ease of Management:

A good network design should ensure that network administrators can easily understand the overall operation status of the network, business flow, and device operation status, thereby achieving efficient network management.

Solution:

Considering the bank's business functions and security scenarios, it needs to be divided into different network zones, each requiring independent network equipment to connect to corresponding servers, PCs, and other devices. Based on the actual project situation, Netlink Communications engineers have planned and designed the network according to standardized, structured, and hierarchical principles. The main network planning topology is as follows:
