NOTE: You should not be using /Library/StartupItems or /System/Library/StartupItems for processes. It is included here as another place to look when you are trying to determine how a process was invoked. Here, you will see any startup items that have already been added to the list, as you can see in the list of Login Items in Figure 2 9. If you find startup items here, take a look at what they do before you become alarmed. A number of third-party tools create a startup item as part of their installation process. However, if you feel you don t need to automatically start the application, delete it here. You can also create one manually by clicking on the plus sign (+) and browsing to the item to be added. While Applications are most commonly launched at login, you can also have documents automatically opened.

We ve spent much of this chapter describing how to categorize processes, how to identify information about a process, and how to interact with the processes. Finally, it s important to look at which processes should and should not be running on your systems. Every process should be reviewed for merit, either by running a quick search

through sites you trust on the Internet or consulting trusted publications for validation. If a process is found not worthy it should be removed. Those processes that are worthy should also be authentic. What do we mean by authentic Virtually any application or service can be plucked from an operating system, altered, then put back into the OS, and run. And it would appear to be a valid service or application if you were to only look at the name of the service. But if a file has been edited, then usually the date and time of creation and/or last modification will change. To add insult to injury, date and time stamps can also be faked. So another good place to look for changes is in its default file size. These are two quick and easy ways to tell if a file has been altered, but they can both be faked (although it is rare that both would be faked at the same time). Therefore, a better method was devised to determine whether an application or service is authentic by having it signed by a Certificate Authority. The signatures of files and folders cannot be faked, and therefore the application becomes signed using PKI. That signature then becomes a means to determine that the application is therefore authentic. Leveraging application signing allows the operating system itself to then validate the authenticity of applications. Because the applications come from vendors, the packages that install applications and the applications themselves should be able to be validated with PKI as well. For more on application signing, see 6.

Throughout this chapter, we have looked at how services, daemons, and processes are started in Mac OS X. Each of these will take up resources on a computer and according to which account invokes them they can each be dangerous. In order to mitigate some of the damage that can be done by a process, we will now turn our attention to managing these users in 3.

Over the years, Apple has gone to great lengths to make OS X strong by hardening its user security. Hardening means strengthening a component in a system to make it more secure. User accounts can be hardened in OS X by limiting the resources users can access. You can accomplish this two ways: by using the built-in GUI tools, or by using the command line. In this chapter, we will go deeper into securing the Mac by focusing first on restricting user access and then on more advanced command-line security that can be used to harden user accounts.
