Web applications are not protected by today's network level firewalls, because they allow access to TCP port 80 without restrictions. However, many successful attacks today are not on the network level, but on application level. For protecting against application level attacks, a firewall must understand the application protocols, that are used on its open ports. This happens in application level firewalls and for Web applications in Web application firewalls. The underlying concepts of Web application firewalls differ much from the concepts of traditional network level firewalls. This book explains the underlying concepts of Web application firewalls. Afterwards, they are applied to a collection of security requirements, that application developers should respect today for developing a secure Web application. A Web application firewall is capable of automatically implementing many of these requirements. As a result, Web application developers can ignore these requirements, because the Web applications firewall already ensures their implementation and therefore the security of the Web application. This book is intended for anyone, who is interested in securing his Web application.

Analyzing modern service and production processes reveals that intensified competition and unpredictable demand fluctuations create significant pressure to reduce costs through efficient process control while optimizing revenue via effective capacity and price management. Research in profit maximization primarily addresses two areas: cost reduction, often focusing on operational control of production schedules and logistics planning, with little emphasis on direct customer interaction; and capacity and price control, which typically examines only one aspect of profit-enhancing Revenue Management. The implementation of a Revenue Management approach must prioritize real-world applicability, particularly in light of unexpected demand fluctuations and unpredictable customer behavior regarding pricing. A viable solution must address these uncertainties to ensure practical information acquisition. In this context, Mr. Becher proposes a concept for integrated capacity and price control in Revenue Management utilizing Fuzzy Expert Controllers. This approach effectively addresses the revenue objectives while considering the inherent uncertainties in the market, providing a comprehensive framework for optimizing revenue in challenging conditions.
