Abstract: Due to insufficient checks on input data in many web applications web servers remain prone to external tampering. This paper proposes ALF (application level firewall) to protect web systems with three new mechanisms. First, ALF provides a fine grained access control policy. Second, ALF allows web application developers to specify the restriction on application running parameters. Finally, ALF collects web user behavior statistics.
Keywords: ALF (Application Level Firewall), Attack Signature, CGI (Common Gateway Interface).
