• Sommario/riassunto: This concise and practical book shows where code vulnerabilities lie-without delving into the specifics of each system architecture, programming or scripting language, or application-and how best to fix themBased on real-world situations taken from the author's experiences of tracking coding mistakes at major financial institutionsCovers SQL injection attacks, cross-site scripting, data manipulation in order to bypass authorization, and other attacks that work because of missing pieces of codeShows developers how to change their mindset from Web site construction to Web sit
