2.4 Deployment Considerations

This section provides an overview of the most important considerations for installing or upgrading Security Agent for UNIX.

Table 2-1 New Installations

Agents	Tool Recommended for New Installation
Secure Configuration Manager	UAM
Sentinel	UAM
Change Guardian	CG AM
Sentinel and Change Guardian	UAM or CG AM
SCM and Change Guardian, and Sentinel	Depends on the following factors: With Change Guardian 4.2.1, use UAM With Change Guardian 5.0 and later, upgraded from 4.2.1 without security communication profile changes, use CG AM With Change Guardian 5.0 and later, upgraded from 4.2.1 and with security communication profile changes, new agent installation for SCM is not supported due to incompatible communication protocols. With new installations of Change Guardian 5.0 and later, new agent deployment for SCM is not supported due to incompatible communication protocols. IMPORTANT:With new installations of Change Guardian 5.0 and later, new agent deployment for SCM is not supported due to incompatible secure communication profile.
Sentinel and SCM	UAM

Table 2-2 Upgrade Paths for Agents With Change Guardian 5.0 Enabled

Existing deployment	Tool Recommended for Upgrade Deployments
Security Agent for UNIX 7.5 with Change Guardian 4.2.1 enabled	Upgrade using the following sequence: Upgrade Change Guardian to 5.0 Migrate hosts. For more information, see Section 5.0, Migrating Hosts from UAM to CG AM. Use CG AM to upgrade agents to 7.5.1
Security Agent for UNIX 7.5 with Change Guardian 4.2.1 and Sentinel 7.x or 8.x enabled	Upgrade using the following sequence: Upgrade Change Guardian to 5.0 Migrate hosts. For more information, see Section 5.0, Migrating Hosts from UAM to CG AM. Use CG AM to upgrade agents to 7.5.1
Security Agent for UNIX 7.5 with Change Guardian 4.2.1, SCM 6.x, and Sentinel 7.x or 8.x enabled	Upgrade using the following sequence: Upgrade UAM and all agents to 7.5.1. For more information see, Upgrading Security Agent for UNIX Using UAM. For Change Guardian, make cipher changes on Change Guardian 4.2.1 to ensure enhanced security on 7.5.1 agents. Upgrade Change Guardian to 5.0

Table 2-3 Upgrade Paths for Security Agent for UNIX 7.5.1 using UAM

Existing deployment	Notes
Security Agent for UNIX 7.5 with Change Guardian 4.2.1 enabled	Requires cipher changes on Change Guardian 4.2.1 because of enhanced security on Security Agent for UNIX 7.5.1.
Security Agent for UNIX 7.5 with Sentinel 7.x or 8.x enabled	-
Security Agent for UNIX 7.5 with SCM 6.x enabled	-
Security Agent for UNIX 7.5 with Change Guardian 4.2.1, SCM 6.x, and Sentinel 7.x or 8.x enabled	For Change Guardian agent, it requires cipher changes on Change Guardian 4.2.1 because of enhanced security on Security Agent for UNIX 7.5.1.
