Windows Server 2003 Recommended Baseline Security (ITSG-20) 1 Introduction 1.1 Background Threat agents exploit vulnerabilities to either gain control or disable a computer. Experts differ on what may be the primary cause of computer vulnerabilities. Some will agree that two causes are exploitation of defects in software, and lack of secure configurations. To address software defects, vendors issue patches in many forms. These are designed to address software defects particular to an operating system or application. Although they fix one problem, patches create other issues. In addition to patches, checklists are used to provide computer users with secure and tested configuration guides. In the past, Government agencies 1 have produced and disseminated checklists for securing computer systems. However, the way checklists are produced has changed. Vendors realize benefits producing configuration checklists for their own products. In turn, public and private organizations save time and money by leveraging this complex work. 1.2 Aim ITSG-20 provides a practical set of security settings for Microsoft Windows Server 2003. The aim is to establish and maintain a High Security Windows Server 2003 environment. There are two platform variants: Domain Server and Workgroup Server. We cover two applications as well: Print Server and File Server. In other words, we provide four configurations, one for each application running on each platform, as follows: 1) Domain File Server 2) Domain Print Server 3) Workgroup File Server 4) Workgroup Print Server The guideline provides a Baseline configuration that applies to all servers of a given type, Domain Server or Workgroup Server. Given that the Baseline configuration provides security before functionality, it should be used as a starting point. File and Print Server application policies are layered on top of the Baseline configuration. In this way, we provide a template for creating additional server roles based on the CSE Baseline. Application policies layered above the Baseline enables the server to function as intended. 1.3 Scope ITSG-20 provides guidance to build High Security Domain and High Security Workgroup servers. Additional policies can be applied to support a variety of roles within your organization. 1 Agencies such as: National Institute of Standards and Technology (NIST), National Security Agency (NSA), Center for Internet Security (CIS), and SANS (SysAdmin, Audit, Network, Security).
