Abstract
Research into web application security is still in its initial phase. In spite of enhancements in web application development, large numbers of security issues remain unresolved. Login attacks are the most malevolent threats to the web application. Authentication is the method of confirming the stated identity of a user. Conventional authentication systems suffer from a weakness that can compromise the defense of the system. An example of such vulnerabilities is login attack. An attacker may exploit a pre-saved password or an authentication credential to log into web applications. An added problem with current authentication systems is that the authentication process is done only at the start of a session. Once the user is authenticated in the web application, the user's identity is assumed to remain the same during the lifetime of the session. This chapter examines the level login attacks that could be a threat to websites. The chapter provides a review of vulnerabilities, threats of login attacks associated with websites, and effective measures to counter them.
