Solaris software provides a sophisticated resource management tool, the Resource Manager. The Resource Manager can help prevent denial of service attacks. With the Resource Manager, you can designate resources for particular projects. You can prevent scripts from overrunning the machine's resources. You can limit the space that a project can occupy. For a description and an extensive example of how to use the Resource Manager, see “Solaris 9 Resource Manager Topics” in System Administration Guide: Resource Management and Network Services.
