Install a single Host Defender

Install Host Defender on each host that you want Prisma Cloud to protect.
Single Host Defenders can be configured in the Console UI, and then deployed with a curl-bash script. Alternatively, you can use twistcli to configure and deploy Defender directly on a host.

Install a Host Defender (Console UI)

Host Defenders are installed with a curl-bash script. Install Host Defender on each host that you want Prisma Cloud to protect.
Prerequisites
:
  • Your system meets all minimum system requirements.
  • You have already installed Console, and it can be accessed over the network from the host where you want to install Defender.
  • Port 8084 is open on the host where Defender runs. Console and Defender communicate with each other over a web socket on port 8084 (by default the communication port is set to 8084 - however, you can specify your own custom port when deploying a Defender).
  • You have sudo access to the host where Defender will be installed.
  1. Verify that the host machine where you install Defender can connect to Console.
    $ curl -sk -D - https://<CONSOLE_IP_ADDRESS|HOSTNAME>:8083/api/v1/_ping

    If curl returns an HTTP response status code of 200, you have connectivity to Console. If you customized the setup when you installed Console, you might need to specify a different port.
  2. Log into Console.
  3. Go to
    Manage > Defenders > Deploy
    .
    1. In the first drop-down menu (2), select the way Defender connects to Console.
      A list of IP addresses and hostnames are pre-populated in the drop-down list. If none of the items are valid, go to
      Manage > Defenders > Names
      , and add a new Subject Alternative Name (SAN) to Console’s certificate. After adding a SAN, your IP address or hostname will be available in the drop-down list.
      Selecting an IP address in a evaluation setup is acceptable, but using a DNS name is more resilient. If you select Console’s IP address, and Console’s IP address changes, your Defenders will no longer be able to communicate with Console.
    2. (Optional) Set a proxy (3) for the Defender to use for the communication with the Console.
    3. (Optional) Set a custom communication port (4) for the Defender to use.
    4. (Optional) Set
      Assign globally unique names to Hosts
      to
      ON
      when you have multiple hosts that can have the same hostname (e.g., autoscale groups, overlapping IP addresses, etc).
      After setting the toggle to
      ON
      , Prisma Cloud appends a unique identifier, such as ResourceId, to the host’s DNS name. For example, an AWS EC2 host would have the following name: Ip-171-29-1-244.ec2internal-i-04a1dcee6bd148e2d.
    5. In the second drop-down list (5), select
      Host Defender - Linux
      or
      Host Defender - Windows
      .
    6. In the final field, copy the install command, which is generated according to the options you selected.
  4. On the host where you want to install Defender, paste the command into a shell window, and run it.

Install a single Host Defender (twistcli)

Use twistcli to install a single Host Defender on a Linux host.
Prerequisites
:
  • Your system meets all minimum system requirements.
  • Console can be accessed over the network from the host where you want to install Defender.
  • You have sudo access to the host where Defender will be installed.
  • You’ve created a service account with the Defender Manager role. twistcl uses the service account to access Console.
  1. Verify that the host machine where you install Defender can connect to Console.
    $ curl -sk -D - https://<CONSOLE>/api/v1/_ping

  2. SSH to the host where you want to install Defender.
  3. Download twistcli.

Verify that Defender is installed and connected to Console.
In Console, go to
Manage > Defenders > Manage
