About The Customer
Landesbank Baden-Württemberg (LBBW) is one of the largest commercial banks in Germany, serving as the central bank for savings banks in the states of Baden-Württemberg, Saxony, and Rhineland Palatinate. LBBW's core activities include retail and corporate banking, real estate financing, and customer-driven capital market business. The bank has systematically centralized its IT applications infrastructure to reduce administration work for its 13,000 IT workstations. LBBW operates from four main locations in Stuttgart, Karlsruhe, Mannheim, and Mainz, along with approximately 200 nationwide branches. The bank's IT infrastructure primarily uses a central Citrix XenApp environment, with most workstation PCs replaced by thin clients.
The Challenge
The central XenApp environment at Landesbank Baden-Württemberg (LBBW) faced significant security challenges. The bank needed to protect its environment from unauthorized software execution, particularly against malware that could be embedded within email attachments, web browsers, or removable storage devices. Additionally, LBBW required a robust compliance and audit policy to ensure user and group-specific access requirements were met. The bank's IT organization needed a multi-level security solution that could prevent unauthorized software from running on its XenApp server farms, ensuring maximum system security and stability.
The Solution
LBBW implemented the AppSense User Virtualization Platform to enhance its security architecture. This platform uses secure capture mechanisms at the kernel level to identify and block unwanted software applications on servers or terminals. It protects against script-based and executable viruses, trojans, and spyware. The AppSense solution also offers control over software content, such as ActiveX, VBScripts, batch files, Windows Installer packages, and configuration files for registration. The platform's comprehensive control functionality allows LBBW to define rules-based policies for application execution for individual groups or users. The solution logs all security-related events for auditing purposes and provides clear error messages to users when an application is blocked. Passive monitoring mode allows LBBW to observe user behavior before implementing new updates, ensuring that security configurations can be adapted accordingly.
Operational Impact
  • The AppSense User Virtualization Platform has become a key strategic component of LBBW's IT infrastructure, ensuring maximum system security by blocking unauthorized applications at the kernel level.
  • The solution provides proactive protection against executable and script-based viruses, spyware, peer-to-peer tools, and hacker tools, ensuring optimal system stability and integrity for 1,500 XenApp servers.
  • The platform's rules-based configuration simplifies user and group-specific access management, enhancing overall system efficiency.
  • Passive monitoring mode supports security configuration by allowing LBBW to observe user behavior before implementing new updates, ensuring that application execution rules can be adapted accordingly.
  • The solution's extensive control functionality enables LBBW to implement internal security policies across the entire company in a highly efficient, user-friendly manner.
Quantitative Benefit
  • Protected 1,500 XenApp servers from unauthorized software.
  • Centralized IT applications infrastructure for 13,000 IT workstations.
  • Implemented security measures across four main locations and approximately 200 nationwide branches.
