Frank Rietta is the CEO of Rietta.com, a Security Focused Web Application Firm. He is a web application security architect, expert witness, author, and speaker. He is a computer scientist with a Masters in Information Security from the College of Computing at the Georgia Institute of Technology. Additionally, he is a contributor to the security chapter of the 7th edition of the "Fundamentals of Database Systems" textbook published by Addison-Wesley. Rietta.com is in the business of defensive security. Our business is built around the realization that security cannot be bolted on at the end of a development process, and thus if you want to build web applications capable of withstanding constant attack from hackers and those who would cause users harm, you have to build security into the development process itself. This has become even more critical with the rise of cloud-based computing and the proliferation of mobile iPhone and Android applications that communicate constantly with publicly accessible web-based API servers to function. In our industry, the security perimeter is no longer defined as a network firewall, but is instead wherever your servers make an authentication decision. This means ultimately all security depends on software security.
