Security and Cryptography

Abstract

Writing secure code is hard. Even in traditional client-server applications, it’s difficult to defend against the vast array of possible threats and attacks. Security considerations stretch across every area of programming, from design to deployment, and include everything from hiding sensitive information to restricting the abilities of different classes of users. Code that runs smoothly, requires user credentials, and uses encryption can still be filled with exploitable security holes. Most often, the professional developers who created it won’t have any idea of the risk until these weaknesses are exploited.
