As businesses grow increasingly dependent upon Web applications to provide services to customers, employees and partners, these complex applications become more difficult to secure. Although traditional security solutions protect Internet infrastructure layers, they do not guard against HTTP and HTML attacks. Many organizations that conduct security testing still deploy applications that allow attackers to manipulate their logic and wreak havoc on their business. To mitigate this risk, development and delivery teams must address Web application security throughout the lifecycle, addressing the many layers detailed in this paper.

Building a software-as-a-service solution requires addressing a few key technical challenges. In this webcast, we'll focus on the role of IBM Tivoli Directory Server and WebSphere Portlet Factory in creating a Software as a Service solution. We will demonstrate how to use Tivoli Directory Server to prevent the user population of one tenant from accessing the virtual portal and portlet components of another tenant. We will also use the dynamic profile capability of WebSphere Portlet Factory to create multiple highly customized applications from one code base.

As businesses grow increasingly dependent upon Web applications, these complex entities grow more difficult to secure. Most companies equip their Web sites with firewalls, Secure Sockets Layer (SSL), and network and host security, but the majority of attacks are on applications themselves – and these technologies cannot prevent them. This paper explains what you can do to help protect your organization, and it discusses an approach for improving your organization’s Web application security.
