The general consensus is that client-side code is more accessible to the bad guys and thus more easily exploited. While there are many things to exploit with rich Internet applications, I’ve had few security problems with them, and here’s why. Most RIAs I’ve encountered have been well-coded with only a minimal set of vulnerabilities, especially compared to older Web technologies. These RIAs aren’t just more secure because they’re using new technologies. Instead, applications are being developed securely up front, with good support from management. It’s obvi- ous that Web 2.0 developers have learned a lesson from Web 1.0 security disasters. That’s half the battle. Project managers have learned from past mistakes, too. More and more, I see managers asking consultants and their own teams for extra security checks of their applications. That’s going to result in more secure systems. I expect these double-checks will be a com- mon practice, as more developers use Web 2.0 technologies and systems become more complex. —K.B. 11 SOFTWARE TESTING MARCH 2009

These controls won’t guarantee Web security, but they create a foundation upon which good security and solid risk management can be built. —K.B. 12 SOFTWARE TESTING MARCH 2009
