When it comes to application vulnerabilities, there are 2 common groups we might view them: Technical Debt and New Development. I break these down because the way in which we address vulnerabilities is fundamentally different. Something that might not be exploitable receives a very low priority when it is technical debt. However, during new development, it can be addressed with little cost. Much of this comes down to if soemthing is syntactically insecure vs. actually vulnerable. Let’s look at … [Read more...] about Technical Debt vs. New Dev
Security takes a layered approach to reduce the risk to our organization. Input validation is the perfect example of one of these layers. In most cases, input validation is 1 factor in a multi-pronged approach to protecting against common vulnerabilities. Take any course on secure development and they will, or should, mention input validation as a mitigating control for so many vulnerabilities. You might notice that it always comes with a but. Use input validation, but also use output … [Read more...] about Input validation is less about specific vulnerabilities
The title might be confusing, let's see if we can clear it up. I saw an article the other day that was giving a comparison between encoding, encryption and hashing. There was a statement made that basically said: Encoding has no security purpose. I thought this was interesting because when training on security topics we mention encoding for specific use cases. For example, when we discuss Cross-Site Scripting, the answer is output encoding. I want to clarify that I agree with the statement … [Read more...] about Is encoding really encoding if it is escaping?
Browsers play a role in web application security, but where does their responsibility stop and the developer's start? In this episode, we are going to discuss a few changes happening in the Chrome browser, that change security by default. Listen to the Episode: SameSite Default Chrome has announced a few changes that we need to watch out for in the near future. We previously talked about the default value for samesite that is coming up fast. I wrote about this here: … [Read more...] about Ep. 117: How Browsers are Helping with Security
Do you rely on the browser to protect your application from Cross-Site Scripting? Over the years, many of the popular browsers attempted to create these XSS filters to help reduce the risk of the vulnerability. Unfortunately, over the years we have seen a lot of bypasses to these filters. Chrome announced they are removing their XSS Auditor. Hear some of our thoughts on the changes. Listen to the Episode: References https://www.chromium.org/developers/design-documents/xss-auditor … [Read more...] about Ep. 116: Chrome Retires XSS Auditor
