This is an example of how a large business might deploy Privilege Manager for Unix. Some global companies prefer to fragment their requirement and deploy multiple instances as shown in the medium-sized business model.
This example comprises three policy servers, two are balancing the load of multiple agents. This may be necessary if there is a high level of audit and/or a significant volume of requested elevated privilege. Further, there is an additional policy server configured as a failover should one or both policy servers become unavailable.
Figure 8: Large Business Implementation
This example is based on an organization with offices in London and New York. Again, as with the medium-sized business example, the web servers and corporate web-based applications reside in a DMZ. The requirement to execute commands at an elevated level from inside the firewall remains.
Access to the web server and web applications is predominantly, but not exclusively, from the London office. Privilege Manager for Unix tunnelling components are used to breach the firewall to the DMZ.
In addition, internal firewalls are located between the offices in London and New York, and tunnelling components are deployed to enable access from office to office and indeed from anywhere to the DMZ.
Within each office, multiple policy servers are configured for load balancing, with each policy server serving a number of agents.
Figure 9: Enterprise Deployment Implementation
You can extend each of the models described above by, for example, adding more policy servers, configuring additional load balancing, assigning dedicated audit, logging and reporting servers. The models provide a small indication of the flexibility and modular way in which you can configure and implement Privilege Manager for Unix to meet the precise requirements of any size business.
This is an overview of the steps necessary to set up your environment to use Privilege Manager software:
To configure a primary policy server
To configure a secondary policy server
To install the PM Agent or Sudo Plugin on a remote host
