At Biztech, we pride ourselves on delivering top-notch IT solutions tailored to the unique needs of our clients. Recently, we assisted a client multiple counties away with a critical security enhancement project. This project involved network segmentation—a key measure to boost security, maintain data privacy, and ensure operation uptime.

Segregated Networks: Enhancing Security and Privacy

Upon assessing the client’s infrastructure needs, our team decided that creating a dedicated, private network for the visiting technician was the best solution. This dedicated network only accessed the six necessary machines, fortifying security and privacy measures. By implementing this design, we ensured that no unauthorized data was accessible to the technician. Our client’s machines could function efficiently without any security compromises, achieving seamless operation uptime.

The Mechanics of Network Segmentation

So, how did we implement it? We assigned the technician to a virtual local area network (VLAN) through a configured switch port, enabling secure and isolated access to the required machines within the broader network infrastructure. In large networks, such segmentation is essential. It creates multiple mini-networks within the broader structure, isolating specific areas that don’t need to interact with each other.

For instance, the maintenance department’s network was separated from the production network. This isolation ensured that machinery operations could proceed independently, without cross-traffic that could lead to performance bottlenecks or security vulnerabilities.

The larger network held several distinct areas, including an ERP system, sales CRM, and other essential departments like accounting and shipping. Each department has unique data needs and access privileges, making segmentation a security measure and a business efficiency tool.

Maintaining these separate “islands” of data ensured that only the necessary information was accessible to each department while protecting sensitive data through restricted access protocols.

For example, the ERP system manages raw materials and production plans, interacting with the manufacturing line. However, data from manufacturing pushes one way to avoid cyclical dependencies that could lead to vulnerabilities. Similarly, the shipping and inventory data flows back into the ERP system post-manufacturing, tying all operational data back to a centralized hub while maintaining security and data integrity.

Customized Dashboards for Executive Reporting

One of the critical aspects of our project was ensuring that executives had clear, real-time visibility across all operations. Each department received a customized dashboard tailored to show metrics relevant to their function—production performance, accounting figures, or shipping statuses. Executives could view hourly, daily, weekly, and monthly reports for comprehensive oversight.

Key Security Aspects of Network Segmentation

1. Separation of Networks

This principle was foundational to our solution. By creating isolated networks, we precisely controlled who could access which data, minimizing the attack surface and preventing unauthorized access. This meticulous control is crucial because not every user can access all network segments.

2. User Authentication and Monitoring

Identifying and monitoring users who bridge multiple network segments was another critical aspect. We employed multi-factor authentication (MFA) to ensure that any crossover between segments happened securely. MFA helps verify the identity of the user logging in, their device, and their location, adding layers of security that reduce the risk of breaches.

3. Secure Device Integration

Ensuring that devices connecting to the network are verified was another key focus. As part of our MFA process, business cell phones played a crucial role, holding authenticators that speed up these security checks without compromising integrity. This method aligns with modern security demands seen in other sectors like banking.

Looking Ahead: Continuous Improvement

Our project with this client proved successful, but there is always room for improvement and adaptation as security landscapes evolve. We continuously seek to enhance our solutions and welcome feedback to make our services even more robust. With each project, we aim to add valuable lessons to our repertoire, ensuring our clients always receive the best possible IT solutions.

Network segmentation is a vital security strategy that offers multiple business benefits—from boosting security and privacy to enhancing operational efficiency. At Biztech, our tailored approach ensures that each client receives solutions that meet their needs while maintaining peak security standards.
