Some blurb

"IDC research consistently finds that customers look forward to a first service pack after a product release to bolster the security of the Windows environment," said Al Gillen, research director for system software at IDC. "In the case of Windows Server 2003 SP1, Microsoft has brought forward not just the normal collection of updates, but several tools that promote more-secure network configuration and a streamlined way to administer the latest security releases."
Service Pack 1 Offers Customers New Security Enhancements
Windows Server 2003 Service Pack 1 provides new functionality to address known security vulnerabilities and prepares companies to better face future security threats. These new technologies include the following:
* Security Configuration Wizard. Customers can more easily reduce attack surface area with the new Security Configuration Wizard. The tool reduces the attack surface by gathering information about specific server roles, then automatically blocking all services and ports not needed to perform those roles.
* Windows Firewall. Customers can increase their security with the new Windows(r) Firewall on the server, allowing networkwide control through Group Policy. Also released with Windows XP Service Pack 2, Windows Firewall serves as a host (software) firewall around each client and server computer on a customer's network.
* Post-Setup Security Updates (PSSU). Servers are vulnerable during the time between their installation and application of the latest security updates. In response, Windows Server 2003 Service Pack 1 blocks all inbound connections to the server after installation until Windows Update has delivered the latest security updates to the new computer.

Other Service Pack 1 features that offer customers a more robust security defense include Internet Information Services (IIS) 6.0 Metabase Auditing, which allows administrators to identify potential malicious users should the store become corrupted, stronger defaults and privilege reduction on services to establish a minimum security threshold for applications, and the addition of Network Access Quarantine Control components to allow administrators to isolate out-of-date virtual private networking (VPN) assets.

"Windows Server 2003 Service Pack 1 has enabled us to take our network security to the next level, and installation was practically seamless," said Jonathan Addington, network administrator at K2 Corp. "With the latest security updates, we've once again reduced our system vulnerability to viruses, worms and hacker attacks, and added functionality that continues to reduce system management costs."
Increased Reliability, Performance and Extensive Testing
Customers also can expect to see an increase in overall reliability and performance with the enhancements in Windows Server 2003 Service Pack 1. Microsoft internal testing shows customers can expect increased performance and reliability up to 50 percent, depending upon workload, after deploying Windows Server 2003 Service Pack 1. In addition, Microsoft worked closely with its hardware and software partners to ensure the highest possible level of application and device compatibility for Service Pack 1. Microsoft tested a wide range of server applications including anti-virus, firewall, database, communication, business intelligence, Web development, financial and more. Microsoft also tested many Windows Server-based devices for compatibility with Service Pack 1.
Microsoft Plans Security Enhancements for Small Businesses Server
