📰 Reddit r/cybersecurity
Learn how distributed firewalls can substitute for network segmentation in a financial services company, and why it matters for cybersecurity
Action Steps
- Assess the current network architecture using VMware distributed firewalls
- Evaluate the sensitivity of systems and data hosted in the environment
- Configure distributed firewalls to create virtual zones for management and database components
- Test the effectiveness of distributed firewalls in isolating sensitive systems
- Compare the complexity and security benefits of distributed firewalls versus traditional network segmentation
Who Needs to Know This
Cybersecurity teams and network administrators can benefit from understanding the trade-offs between distributed firewalls and network segmentation, especially in complex environments with sensitive systems
Key Insight
💡 Distributed firewalls can be a viable alternative to network segmentation, but require careful configuration and testing to ensure effective isolation of sensitive systems

I am reviewing cyber controls for a financially services company which uses VMware distributed firewalls on its VMs. They have a sensitive system hosted in a separate environment. This environment is not externally accessible and host database components and a few management components. As per policy two separate zones should be created - 1) management and 2) secured zone for database, however to avoid complexity, management has not created separate zones
