TIP: In highly sensitive environments, it may be desirable to compile a custom copy of mtree to run from read-only media. This ensures that your auditing tool itself cannot be compromised. Consider scheduling routine checks against critical directories on your system to warn you of any issues. The default system path is a good place to start here: /usr/bin:/bin:/usr/sbin:/sbin. If you have installed programs at /usr/local, you may also want to monitor that hierarchy. The /etc/ folder also contains important configuration files which you may want to monitor for modification. If your systems contain valuable or sensitive data, then it is always a good idea to audit your system s security. Through the mtree binary, OS X provides a built-in tool that does a pretty good job of accomplishing this. The mtree tool certainly isn t as extensive as tools such as Tripwire, but it does its job well and is fairly easy to use.

This chapter introduced you to web services and their architecture. You looked at the theory of web services and how the group of technologies HTTP, SOAP, XML, and WSDL are used in the Web Services ecosystem. You then looked into how to create a web service using Visual Studio and Visual Web Developer Express. You looked into how to tie a web service to databases using DataSets, and finally you built a web service client by using the IDE to access the WSDL document for your web service to generate a proxy class.

Another place for this is the default EC2 environment, where users will be working on virtual machines all day long, but will only write changes back in if they save a copy of the machine into a local space, such as their S3 account. It also makes for a nice way to store images (and images containing packages) during the imaging process for a number of environments.
