Apply Security Policies to the VM-Series Firewall on NSX-T (East-West)

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.
  1. Create security policy rules.
    1. Select
    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
      and enter a
      and a
      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
      Destination Zone
      . The zone name must be the same in both columns.
    5. For the
      Source Address
      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
      to allow. In this example, we create an
      Application Group
      that includes a static group of specific applications that are grouped together.
      1. Click
        and select
        New Application Group
      2. Click
        to select the application to include in the group.
      3. Click
        to create the application group.
    7. Specify the action—
      —for the traffic, and optionally attach the default security profiles for antivirus, anti-spyware, and vulnerability protection, under Profiles.
    8. Repeats the steps above to create the pertinent policy rules.
    9. Click
      , select Commit Type as
      . Click
  2. Apply the policies to the VM-Series firewalls for NSX-T.
    1. Click
      , and select Commit Type
      Device Groups
    2. Select the device group, NSX-T Device Group in this example and click
    3. Verify that the commit is successful.
  3. 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
      , and select a rule.
    3. Select the drop-down arrow next to the address group link, and select
      . You can also verify that the match criteria is accurate.
    4. Click the
      link and verify that the list of registered IP addresses is displayed.
      Policy will be enforced for all IP addresses that belong to this address group, and are displayed here.
  4. (
    ) 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.
  5. 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 intra-tier and inter-tier 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
    2. Select
      Network Profiles
      Zone Protection
      to add and configure a new profile.
    3. Select
      , click the default-zone listed and select the profile in the
      Zone Protection Profile
      drop down.
  6. Create a DoS Protection profile and attach it to DoS Protection policy rule.
    1. Select your
      Device Group
    2. Select
      Security Profiles
      DoS 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 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
      DoS Protection,
      and attach the new profile to it.
