Network Segmentation

As cloud computing and connected devices become a standard part of enterprise IT, corporate networks are growing more complex by the day—opening new doors for cyberattackers to infiltrate sensitive data and systems. If your organization relies upon endpoints owned and operated by third parties, compliance and security can be a challenge. Burwood Group can help you adopt network segmentation strategies that limit a would-be attacker to a single subnet.

Network segmentation is based on the “zero trust” model of information security, in which your IT team can enforce security across your networks as traffic travels to endpoints. With the right design, network segmentation improves cybersecurity while also lightening your compliance load. That’s why it is quickly becoming a best practice for Burwood Group and our clients.

It's critical to protect all data from the inside out, going far beyond traditional endpoint protection. As the volume of connected devices and remote access points continues to grow, so does the challenge of managing administrative access and ensuring up-to-date security patches. Even routine use of email or file-sharing applications can open the door to costly attacks. For example, a healthcare organization saw a virus spread rapidly across its system after a user downloaded a contaminated file from a file-sharing application.

Segmentation can contain such risks before they spread. Our approach is based on key principles for ensuring security and compliance, while providing access for authorized users:

  • Provide secure access to resources. Protect your network whether users are accessing resources on the premises or from a remote access point.

  • Allow access and connections on a "need-to-know" basis. Separate devices and networks that are needlessly connected. In a manufacturing setting, for instance, third-party production systems may be connected to the enterprise network—creating a major vulnerability with no business purpose.

  • Verify that users, apps and content are legitimate. Create an access control system to give access to sensitive applications and data only to authorized users and devices.

  • Implement ongoing inspections and maintain logs. Ongoing monitoring enables your team to review access activity and determine whether and for how long unusual activity has been underway.

Burwood Group can help you uncover network vulnerabilities and create a segmentation strategy tailored for your environment. Through segmentation, we help you gain greater control over your systems and a deeper look at network traffic and activity.

First, we help you identify networks, data and devices that would benefit from segmentation. Rather than attempting to segment all aspects of your network, we help you prioritize the risks and requirements. And, we help you select the right tools for managing network segmentation and ongoing security, such as Palo Alto Network’s GlobalProtect and Cisco’s TrustSec. 

Traditional endpoint security strategies are no match for today’s complex networks, regulations and modes of working. Burwood Group can help you adopt network segmentation strategies that reduce the risks and control the damage should an intrusion occur.
