Ep. 116: Chrome Retires XSS Auditor
Do you rely on the browser to protect your application from Cross-Site Scripting?

Investing in People for Better Application Security

I feel like we are stuck at this crossroad where the arrow points both ways. The good news is that none of these recommendations are wrong. We do need to … [Read more...] about Investing in People for Better Application Security
What is the difference between source code review and static analysis?
Static analysis is the process of using automation to analyze the application's code base for known security patterns. It uses different methods, such as following data from it source (input) to its sink (output) to identify potential weaknesses. It also uses simple search methods in an attempt to identify hard-coded values, like passwords in the code. Automated tools struggle at finding business logic or authentication/authorization flaws. Code Review is a much larger project where both … [Read more...] about What is the difference between source code review and static analysis?
Interesting Browser Difference
Update 8/16/19 - It appears that not long after I published this, Chrome sent an update that now mimics FireFox. In Chrome you now get a new tab that has a URL of "about:blank#blocked".

I have posted previously on the ability to execute XSS when you control the HREF attribute of a link tag. This is done by setting a url to javascript:alert(9);.
