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.

Join this webcast to see how IBM Data Studio Developer and pureQuery can take the pain out of Java data access. uApplications developed using both Java and SQL have become a common requirement. Database connectivity using Java Database Connectivity (JDBC) to create an application is a multi-step tedious process, and tooling that covers both SQL and Java has been unavailable, until now. IBM Data Studio introduces the pureQuery platform: a high-performance, Java data access platform focused on simplifying the tasks of developing, managing, and optimizing database applications and services.

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.
