Securing GroupWise 6.5 for SUSE Linux Enterprise Server 8 and Novell Nterprise Linux Services 1.0

The purpose of this document is to help readers properly secure a Novell GroupWise 6.5 (GroupWise) environment installed on SUSE Linux Enterprise Server 8 (SLES) using Novell Nterprise Linux Services 1.0 (NNLS). We begin by providing information pertaining to the installation environment that is used throughout the document. We'll start working with OS security by properly securing our installation of SLES. Commonly required services that can cause extra vulnerabilities are also secured. Following the hardening of SLES, we continue by addressing NNLS security, particularly the components required to support the subsequent installation of GroupWise. Finally, the initial installation of GroupWise will be hardened to provide a more secure environment. Once the above steps are complete, a functionally secured GroupWise environment will be ready for deployment. In conclusion, we discuss expanding this scenario to include such issues as growth and scalability. Securing every aspect of each component is worthy of complete books (if not volumes) on each subject. For this reason, we will be applying best-practice security measures that secure the environment in general, as a whole. Resources for more detailed and complex configurations are noted throughout this document.
