If you have One World, it looks like it may be built-in: Also available with this latest release of NetSuite OneWorld is the Administration and Controls Toolkit (ACT) SuiteSolution, which provides a powerful set of new tools for managing access, security, and audit controls. The ACT SuiteSolution contains extensible modules for tracking (and preventing) record deletion, managing employee terminations (pre-dating terminations as well as automated access removal from non-production environments), enhanced security around SuiteScript file management, and a robust audit and change management dashboard for at-your-fingertips, real-time, visibility into key configuration and controls changes. - http://www.netsuite.com/portal/company/pressreleases/05-17-16b.shtml
