Answer : A

Step-by-Step Guide

Creating Tags and Security Groups

First, log into the NSX-T Manager GUI and navigate to Inventory > Tags to create tags like 'BOSTON-Web' for web servers and assign virtual machines such as BOSTON-web-01a and BOSTON-web-02

a. Repeat for 'BOSTON-App' and 'BOSTON-DB' with their respective VMs. Then, under Security > Groups, create security groups (e.g., 'BOSTON Web-Servers') based on these tags to organize the network logically.

Excluding Virtual Machines

Next, go to Security > Distributed Firewall > Exclusion List and add the 'core-A' virtual machine to exclude it from firewall rules, ensuring it operates without distributed firewall restrictions.

Defining Custom Services

Check Security > Services for existing services. If 'TCP-9443' and 'TCP-3051' are missing, create them by adding new services with the protocol TCP and respective port numbers to handle specific application traffic.

Setting Up the Policy and Rules

Create a new policy named 'BOSTON-Web-Application' under Security > Distributed Firewall > Policies. Add rules within this policy:

Allow any source to 'BOSTON Web-Servers' for HTTP/HTTPS.

Permit 'BOSTON Web-Servers' to 'BOSTON App-Servers' on TCP-9443.

Allow 'BOSTON App-Servers' to 'BOSTON DB-Servers' on TCP-3051. Finally, save and publish the policy to apply the changes.

This setup ensures secure, segmented traffic for the 3-tier web application, an unexpected detail being the need to manually create custom services for specific ports, enhancing flexibility.

Survey Note: Detailed Configuration of Micro-Segmentation Policy in VMware NSX-T Data Center 3.x

This note provides a comprehensive guide for configuring a micro-segmentation policy for a 3-tier web application in VMware NSX-T Data Center 3.x, based on the task requirements. The process involves creating tags, security groups, excluding specific virtual machines, defining custom services, and setting up distributed firewall policies. The following sections detail each step, ensuring a thorough understanding for network administrators and security professionals.

Background and Context

Micro-segmentation in VMware NSX-T Data Center is a network security technique that logically divides the data center into distinct security segments, down to the individual workload level, using network virtualization technology. This is particularly crucial for a 3-tier web application, comprising web, application, and database layers, to control traffic and enhance security. The task specifies configuring this for a production environment, with notes indicating passwords are in user_readme.txt and no need to wait for configuration changes, as processing may take time.

Step-by-Step Configuration Process

Step 1: Creating Tags

Tags are used in NSX-T to categorize virtual machines, which can then be grouped for policy application. The process begins by logging into the NSX-T Manager GUI, accessible via a web browser with admin privileges. Navigate to Inventory > Tags, and click 'Add Tag' to create the following:

Tag name: 'BOSTON-Web', assigned to virtual machines BOSTON-web-01a and BOSTON-web-02a.

Tag name: 'BOSTON-App', assigned to BOSTON-app-01a.

Tag name: 'BOSTON-DB', assigned to BOSTON-db-01a.

This step ensures each tier of the application is tagged for easy identification and grouping, aligning with the attachment's configuration details.

Step 2: Creating Security Groups

Security groups in NSX-T are logical constructs that define membership based on criteria like tags, enabling targeted policy application. Under Security > Groups, click 'Add Group' to create:

Group name: 'BOSTON Web-Servers', with criteria set to include the 'BOSTON-Web' tag.

Group name: 'BOSTON App-Servers', with criteria set to include the 'BOSTON-App' tag.

Group name: 'BOSTON DB-Servers', with criteria set to include the 'BOSTON-DB' tag.

This step organizes the network into manageable segments, facilitating the application of firewall rules to specific tiers.

Step 3: Excluding 'core-A' VM from Distributed Firewall

The distributed firewall (DFW) in NSX-T monitors east-west traffic between virtual machines. However, certain VMs, like load balancers or firewalls, may need exclusion to operate without DFW restrictions. Navigate to Security > Distributed Firewall > Exclusion List, click 'Add', select 'Virtual Machine', and choose 'core-A'. Click 'Save' to exclude it, ensuring it bypasses DFW rules, as per the task's requirement.

Step 4: Defining Custom Services

Firewall rules often require specific services, which may not be predefined. Under Security > Services, check for existing services 'TCP-9443' and 'TCP-3051'. If absent, create them:

Click 'Add Service', name it 'TCP-9443', set protocol to TCP, and port to 9443.

Repeat for 'TCP-3051', with protocol TCP and port 3051.

This step is crucial for handling application-specific traffic, such as the TCP ports mentioned in the policy type (TCP-9443, TCP-3051), ensuring the rules can reference these services.

Step 5: Creating the Policy and Rules

The final step involves creating a distributed firewall policy to enforce micro-segmentation. Navigate to Security > Distributed Firewall > Policies, click 'Add Policy', and name it 'BOSTON-Web-Application'. Add a section, then create the following rules:

Rule Name: 'Any-to-Web'

Source: Any (select 'Any' or IP Address 0.0.0.0/0)

Destination: 'BOSTON Web-Servers' (select the group)

Service: HTTP/HTTPS (predefined service)

Action: Allow

Rule Name: 'Web-to-App'

Source: 'BOSTON Web-Servers'

Destination: 'BOSTON App-Servers'

Service: TCP-9443 (custom service created earlier)

Action: Allow

Rule Name: 'App-to-DB'

Source: 'BOSTON App-Servers'

Destination: 'BOSTON DB-Servers'

Service: TCP-3051 (custom service created earlier)

Action: Allow

After defining the rules, click 'Save' and 'Publish' to apply the policy. This ensures traffic flows as required: any to web servers for HTTP/HTTPS, web to app on TCP-9443, and app to database on TCP-3051, while maintaining security through segmentation.

Additional Considerations

The task notes indicate no need to wait for configuration changes, as processing may take time, and steps are not dependent, suggesting immediate progression is acceptable. Passwords are in user_readme.txt, implying the user has necessary credentials. The policy order is critical, with rules processed top-to-bottom, and the attachment's 'Type: TCP-9443, TCP-3051' likely describes the services used, not affecting the configuration steps directly.
