Rackspace PDR on Azure

Rackspace Proactive Detection & Response (PDR) on Microsoft® Azure® has two main components that must be implemented in your Azure environment: the Network-based Intrusion Detection (NIDS) appliance infrastructure must be set up and select vendor agents must be deployed.

Deployment of a NIDS Appliance Infrastructure

To enable visibility of your Azure network, we deploy NIDS appliances into each distinct network environment.

NIDS Appliance Platform Requirements

At this time, the Rackspace Azure and PDR support teams deploy, manage, and monitor your NIDS appliances. Our current NIDS appliances are provided by the Alert Logic® Threat Manger™ offering. Rackspace PDR has the following platform requirements:

  • Be a Rackspace Azure customer.
  • Have a NIDS appliance for each routable network segment (appliance needs to be reachable by agents and vice versa).
  • Set up egress and ingress firewall rules (NSGs) as defined in Rackspace PDR Threat Manager Network Requirements.

Secure Socket Layer (SSL) Appliance End-to-end Decryption

Many applications terminate SSL and Transport Layer Security (TLS) at the network edge with a load-balancer or web application firewall. If your application uses end-to-end encryption, see the
Rackspace PDR SSL Decryption Guide.

Deployment of Vendor Agents

Individual PDR agents are deployed and maintained by the Rackspace PDR team. However, we do have base
requirements that must be met to ensure that our automated deployment system and PDR support team can access your instances to deploy or troubleshoot agents and systems.

Ensure that your virtual machine (VM) images have the Azure Virtual Machine Agent (VM Agent). See the following documentation for more information on installing the VM Agent:

Building Compatible Instances

Due to the various vendors that we have selected to provide the necessary telemetry to our systems, it is important that you select operating systems and kernel versions that are compatible with the vendor agents. For more information, see the Rackspace PDR system requirements.

Golden or Base Images

It is important that images taken from hosts that have Rackspace PDR agents deployed be prepared for deployment before using them as base images. Follow the Rackspace PDR imaging hosts guide to ensure that Golden images are properly prepared.

Instance Network Requirements

The agents used to provide telemetry to our Security Operations Center (SOC) do have specific networking requirements that must be implemented. Use the Rackspace PDR Agent network requirements guide to correctly implement network ACLs and firewall rules for your platform.
