Lear how to apply Security Policies to the VM-Series Firewall on NSX-T (East-West)

Where Can I Use This?	What Do I Need?
VMware NSX	VM-Series Firewall License (BYOL) Panorama VM-Series plugin Panorama plugin for NSX

Now that you have defined the steering rules, you can now use Panorama for centrally administering policies on the VM-Series firewalls.

To manage centralized policy, attach the Dynamic Address Group as a source or destination address in security policy and push it to the firewalls; the firewalls can dynamically retrieve the IP addresses of the virtual machines that are included in each security group to enforce compliance for traffic that originates from or is destined to the virtual machines in the specified group.

Create security policy rules.
1. Select PoliciesSecurityPrerules.
2. Select the Device Group that you created for managing the VM-Series firewalls on NSX-T in Create Template Stacks and Device Groups on Panorama.
3. Click Add and enter a Name and a Description for the rule. In this example, the security rule allows all traffic between the WebFrontEnd servers and the Application servers.
4. Select the Source Zone and Destination Zone. The zone name must be the same in both columns.
5. For the Source Address and Destination Address, select or type in an address, address group or region. In this example, we select an address group, the Dynamic Address Group you created previously.
6. Select the Application to allow. In this example, we create an Application Group that includes a static group of specific applications that are grouped together.
  Click Add and select New Application Group.
  Click Add to select the application to include in the group.
  Click OK to create the application group.
7. Specify the action— Allow or Deny—for the traffic, and optionally attach the default security profiles for antivirus, antispyware, and vulnerability protection, under Profiles.
8. Repeats the steps above to create the pertinent policy rules.
9. Click Commit, select Commit Type as Panorama. Click OK.
Apply the policies to the VM-Series firewalls for NSX-T.
1. Click Commit, and select Commit Type Device Groups.
2. Select the device group, NSX-T Device Group in this example and click OK.
3. Verify that the commit is successful.
Validate that the members of the Dynamic Address Group are populated on the VM-Series firewall.
1. From Panorama, switch device context to launch the web interface of a firewall to which you pushed policies.
2. On the VM-Series firewall, select PoliciesSecurity, and select a rule.
3. Select the drop-down arrow next to the address group link, and select Inspect. You can also verify that the match criteria are accurate.
4. Click the more link and verify that the list of registered IP addresses is displayed.
  
  The policy will be enforced for all IP addresses that belong to this address group, and are displayed here.
(Optional) Use template to push a base configuration for network and device configuration such as DNS server, NTP server, Syslog server, and login banner.
Refer to the Panorama Administrator’s Guide for information on using templates.
Create a Zone Protection profile and attach it to a zone.
A zone protection profile provides flood protection and has the ability to protect against port scanning, port sweeps, and packet-based attacks. It allows you to secure intratier and intertier traffic between virtual machines within your data center and traffic from the internet that is destined to the virtual machines (workloads) in your data center.
1. Select your Template.
2. Select NetworkNetwork ProfilesZone Protection to add and configure a new profile.
3. Select NetworkZones, click the default-zone listed and select the profile in the Zone Protection Profile drop down.
Create a DoS Protection profile and attach it to a DoS Protection policy rule.
1. Select your Device Group.
2. Select ObjectsSecurity ProfilesDoS Protection to add and configure a new profile.
  A classified profile allows the creation of a threshold that applies to a single source IP. For example, you can configure a max session rate for an IP address that matched the policy, and then block that single IP address once the threshold is triggered.
  An aggregate profile allows the creation of a max session rate for all packets matching the policy. The threshold applies to the new session rate for all IP addresses combined. Once the threshold is triggered, it affects all traffic that matches the policy.
3. Create a new DoS Protection policy rule in PolicyDoS Protection, and attach the new profile to it.
