ArcNews Fall 2005 Issue -- ArcGIS Enterprise Security Controls White Paper Available: "ArcGIS Enterprise Security Controls White Paper Available ESRI is providing a white paper describing enterprise security controls for ArcGIS client/server, Web application, and Web services architectures entitled ArcGIS Enterprise Security: Delivering Secure Solutions. It can be downloaded from the ESRI Web site (www.esri.com/enterprisesecurity). Effective enterprise security can be a challenge for the IT architects and security specialists who design, deploy, and support mission-critical solutions. Until the last few years, entire IT systems were frequently designed around a single mission objective and 'community of interest.' The result was physically isolated systems, each maintaining its own data stores and applications. Integration was accomplished through complicated interfaces that replicated and synchronized data among the various systems. Security was generally enforced at the perimeter; any authorized user, once granted entry to a system, could access all data and applications, including GIS applications, resident in the system. Maintaining such 'islands of automation' is expensive and inefficient and does not offer the flexibility or, in many cases, the in-depth security that organizations are seeking."
