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.

Because access to government information continues to be an area of concern for many U.S. citizens with disabilities, the U.S. government enacted Section 508 of the Rehabilitation Act in 2001 to ensure that government agencies create accessible Web content, enabling all citizens to access the information they need. A fully accessible Web site makes Web content accessible to all individuals, including those with disabilities, who may be accessing Web content via a variety of user agents. Common user agents include standard Web browsers, text-only browsers, assistive devices and mobile devices such as cell phones or personal digital assistants (PDAs).
