In this chapter, we look at some of the new tools available to the HP-UX administrator to help secure and manage an HP-UX system. These tools range from Secure Shell to encryption technologies allowing us to secure all our applications over an IP network. Many of these tools are new. We briefly look at them in operation and discuss when and if their use may be appropriate. It must be said that we cannot afford detailed discussions on all these tools. I would strongly suggest that you go over the references at the end of the chapter to gain more insight into the technologies behind this new breed of tools, utilities, and infrastructure applications.
