About Securing Operating Systems

Securing operating systems is the first step towards safeguarding the Siebel Business Applications deployment from intrusion. Workstations and servers are typically installed with a multitude of development tools and utilities. Securing an operating system involves the removal of all nonessential tools, utilities, and other system administration options. This process also requires that all appropriate security features are activated and configured correctly, and includes the following tasks:

• Protecting files and resources

• Restricting accounts and services to those who need them

• Applying and maintaining patches and product updates

• Performing maintenance activities, such as running security software

Note: Before implementing the security recommendations for operating systems described in this chapter, perform all the security steps outlined in your operating system documentation. Security guidelines for operating systems are generally available on vendor Web sites.
