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?

Listen to the Episode: References https://www.chromium.org/developers/design-documents/xss-auditor … [Read more...] about Ep. 116: Chrome Retires XSS Auditor

Application security, like any facet of security, is a complex challenge with a mountain of solutions. Of course, no one solution is complete. Even throwing multiple solutions will never get 100% coverage. The push today is around devsecops, or pushing left in the SDLC. I am seeing more solutions recommending also pushing right in the SDLC. 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
