Configuration Guide
Learn how to configure BigFix according to your needs.
- Introduction
  This guide explains additional configuration steps that you can run in your environment after installation.
- BigFix Site Administrator and Console Operators
  In BigFix there are two basic classes of users.
- Integrating with LDAP
  You can add Lightweight Directory Access Protocol (LDAP) associations to BigFix.
- Enabling SAML V2.0 authentication for LDAP operators
  Starting from Version 9.5.5, BigFix supports SAML V2.0 authentication via LDAP-backed SAML identity providers.
- Using multiple servers (DSA)
  Here are some of the important elements of multiple server installations:
- Server object IDs
  The BigFix server generates unique IDs for the objects that it creates: Fixlets, tasks, baselines, properties, analysis, actions, roles, custom sites, computer groups, management rights, subscriptions.
- Customizing HTTPS for Gathering
  You can gather license updates and external sites by using the HTTP or HTTPS protocol on a BigFix server or in an airgapped environment.
- Configuring secure communication
- Real Time AV Exclusions
  BigFix Console, Server and Relay components of the architecture perform high volume file operations.
- Downloading files in air-gapped environments
  In air-gapped environments, to download and transfer files to the main BigFix server, use the Airgap utility and the BES Download Cacher utility.
- Getting client information by using BigFix Query
  The BigFix Query feature allows you to retrieve information and run relevance queries on client workstations from the WebUI BigFix Query Application or by using REST APIs.
- Persistent connections
  Starting from Patch 11, the capability to establish persistent connections was added to the product.
- Relays in DMZ
  Starting from Patch 13, the capability to establish a persistent TCP connection between the parent relay in the more secure zone and its child relay inside the DMZ network was added to the product. This allows you to manage systems in a demilitarized zone (DMZ network).
- Working with PeerNest
  The BigFix client includes a new feature named PeerNest, that allows to share binary files among clients located in the same subnet. The feature is available starting from BigFix Version 9.5 Patch 11.
- Archiving Client files on the BigFix Server
  You can collect multiple files from BigFix clients into an archive and move them through the relay system to the server.
- BigFix Configuration Settings
  A number of advanced BigFix configuration settings are available that can give you substantial control over the behavior of the BigFix suite. These options allow you to customize the behavior of the BigFix server, relays, and clients in your network.
- Additional configuration steps
  These topics explain additional configuration steps that you can run in your environment.
- Migrating the BigFix Server (Windows/MS-SQL)
  This section details the steps and operational procedures necessary for migrating the BigFix Server from existing hardware onto new computer systems.
- Migrating the BigFix Server (Linux)
  This section provides basic information on migrating your BigFix Server from existing Linux hardware onto new systems.
- Server audit logs
  Starting with BigFix version 9.5.11, the server audit logs include the following items:
- List of advanced options
  The following lists show the advanced options that you can specify in the Advanced Options tab of the BigFix Administrative tool on Windows systems, or in the BESAdmin.sh command on Linux systems using the following syntax:
- Security Configuration Scenarios
  BigFix provides the capability to follow the NIST security standards by configuring an enhanced security option.
  - On Windows Systems
    You can set the enhanced security option by performing the following steps:
  - On Linux Systems
    You can set the security options after you install BigFix V9.5 or upgrade it to V9.5, by running the following command as super user:
- Client Authentication
  Client Authentication extends the security model used by BigFix to encompass trusted client reports and private messages.
- Maintenance and Troubleshooting
  If you are subscribed to the Patches for Windows site, you can ensure that you have the latest upgrades and patches to your SQL server database servers.

On Linux Systems

You can set the security options after you install BigFix V9.5 or upgrade it to V9.5, by running the following command as super user:

./BESAdmin.sh -securitysettings -sitePvkLocation=<path+license.pvk> 
              -enableEnhancedSecurity -requireSHA256Downloads

Note: The notation <path+license.pvk> used in the command syntax stands for path_to_license_file/license.pvk.

The full syntax of the ./BESAdmin.sh -securitysettings is the following:

./BESAdmin.sh -securitysettings -sitePvkLocation=<path+license.pvk> 
   [-sitePvkPassword=<password>]
   { -status | {-enableEnhancedSecurity|-disableEnhancedSecurity} 
   | {-requireSHA256Downloads|-allowSHA1Downloads} }

where:

status

Shows the status of the security settings in your BigFix environment.

Example:

BESAdmin.sh -securitysettings -sitePvkLocation=/root/backup/license.pvk
-sitePvkPassword=mypassw0rd -status

Enhanced security is currently ENABLED
SHA-256 downloads are currently OPTIONAL

enableEnhancedSecurity | disableEnhancedSecurity

Enables or disables the enhanced security that adopts the SHA-256 cryptographic digest algorithm for all digital signatures as well as content verification and the TLS 1.2 protocol for communications among the BigFix components.

Warning: If you use this setting you break backward compatibility because BigFix version 9.0 or earlier components cannot communicate with BigFix version 9.5 server or relays.

requireSHA256Downloads

Ensures that data has not changed after you download it using the SHA-256 algorithm.

Note: You can set requireSHA256Downloads only if you also set enableEnhancedSecurity.

allowSHA1Downloads

Ensures that the file download integrity check is run using the SHA-1 algorithm.
