Deployment Guide
This document provides guidance for deploying the certificate enrollment infrastructure required for BigFix Mobile Configuration Management (MCM). It describes how to integrate BigFix MCM with Microsoft certificate services to enable device certificate enrollment using the Simple Certificate Enrollment Protocol (SCEP).
- Deployment architecture
  The following diagram illustrates the deployment architecture for integrating BigFix MCM with the certificate enrollment infrastructure. It shows the key components involved in the certificate enrollment workflow, including Active Directory, Microsoft Certificate Authority (CA), Network Device Enrollment Service (NDES), NDES Proxy, LDAP Proxy, and BigFix components.
- Infrastructure prerequisites
  Before configuring certificate enrollment for BigFix MCM, ensure that the required infrastructure components and access permissions are available. The certificate enrollment workflow relies on integration between Active Directory, Microsoft Certificate Services, NDES, and BigFix components.The following prerequisites should be verified before proceeding with the configuration steps described in this guide.
- Active Directory setup
  Active Directory provides the directory services required for integrating Microsoft Certificate Authority (CA) and Network Device Enrollment Service (NDES). The following steps ensure that the Active Directory environment is properly prepared before configuring the certificate enrollment infrastructure.
- Certificate Authority (CA) Configuration
  The Microsoft Certificate Authority (CA) is responsible for issuing certificates requested through Network Device Enrollment Service (NDES) using the Simple Certificate Enrollment Protocol (SCEP).This section describes the required configuration on an existing Enterprise Certificate Authority to support certificate enrollment.
- SCEP Certificate Template Configuration
  A custom certificate template must be created to support SCEP-based certificate enrollment with required security and key configurations.
- NDES Installation and Configuration
  The Network Device Enrollment Service (NDES) provides the SCEP interface that allows devices managed by BigFix MCM to request certificates from the Microsoft Certificate Authority. This section describes how to install and configure NDES and verify that it is ready to process certificate enrollment requests.
- NDES Proxy Configuration
  This document provides step-by-step instructions for installing and configuring HAProxy as a proxy for the Network Device Enrollment Service (NDES), covering both challenge and certificate enrollment requests.
- LDAP Proxy Configuration
  This section provides step-by-step instructions to install and configure OpenLDAP as an LDAP proxy on RHEL 8.
- BigFix Configuration for Certificate Enrollment
  This section describes how to configure BigFix MCM to integrate with the certificate enrollment infrastructure using NDES Proxy and LDAP Proxy.
- SCEP Profile Configuration in BigFix
  This section describes how to create and configure a SCEP profile in BigFix MCM to enable device certificate enrollment using the configured NDES Proxy infrastructure.
- Communication Ports and Network Flow
  This section describes the network communication paths and required ports between components involved in the certificate enrollment workflow for BigFix MCM.
- Certificate Enrollment Flow
  This section describes the end-to-end certificate enrollment flow for devices managed by BigFix MCM, using MCM Proxy, NDES Proxy, and Microsoft Certificate Authority.
