Osiris is one of the most widely deployed open source host integrity monitoring systems available today. Osiris can monitor everything from UNIX environments like AIX and Mac OS X, to Windows desktops systems and servers. Osiris can monitor files, network ports, users, groups, and various elements of the kernel and administrator services. One of the biggest advantages of Osiris is that it is quite simple to use. Usability and simplicity were critical goals in the design of the Osiris system. The less complicated your Osiris deployment is, the more likely you will be successful in monitoring the integrity of your environments. The more complicated your Osiris deployment is, the more likely you will end up ignoring it altogether.

In this chapter we have covered all of the steps involved in deploying a simple and effective Osiris deployment. Some of the more complicated features of Osiris were intentionally left out. To find more information about Osiris, I recommend consulting the most current online documentation.
