Security

This content is now available in the Pluralsight course "OWASP Top 10 Web Application Security Risks for ASP.NET" [http://www.pluralsight.com/courses/owasp-top10-aspdotnet-application-security-risks] If your app uses a web server, a framework, an app platform, a database, a network or contains any code, you’re at risk of security misconfiguration. So that would be all of us then. The truth is, software is complex business. It’s not so much that the practice of writing code is tricky (in fact I’...

Finally they’ve delivered! Earlier today the much awaited padding oracle patch was released by Microsoft. As usual, Scott Guthrie has written about it and you can find all the info in ASP.NET Security Update Now Available [http://weblogs.asp.net/scottgu/archive/2010/09/28/asp-net-security-update-now-available.aspx] . It’s not a moment too soon either. According to Thai Duong [http://vnhacker.blogspot.com/], half of the duo responsible for bringing the vulnerability in ASP.NET to public awarenes...

The last week hasn’t been particularly kind to ASP.NET, and that’s probably a more than generous way of putting it. Only a week ago now, Scott Guthrie wrote about an Important ASP.NET Security Vulnerability [http://weblogs.asp.net/scottgu/archive/2010/09/18/important-asp-net-security-vulnerability.aspx] ; the padding oracle exploit. I watched with interest as he was flooded with a barrage of questions (316 as of now) and realised that whilst he’d done his best to explain the mitigation, he obvio...

You’ve gotta feel a bit sorry for Scott Guthrie. Microsoft’s developer division VP normally spends his time writing about all the great new work his team is doing and basking in the kudos of loyal followers. But not this weekend. Unfortunately his latest post [http://weblogs.asp.net/scottgu/archive/2010/09/18/important-asp-net-security-vulnerability.aspx] has been all about repeating the same dire message; ASP.NET has a major security flaw posing a critical vulnerability to millions of websites...

This content is now available in the Pluralsight course "OWASP Top 10 Web Application Security Risks for ASP.NET" [http://www.pluralsight.com/courses/owasp-top10-aspdotnet-application-security-risks] Consider for a moment the sheer volume of information that sits out there on the web and is accessible by literally anyone. No authentication required, no subversive techniques need be employed, these days just a simple Google search can turn up all sorts of things. And yes, that includes content wh...

A couple of Saturdays back I had a chat with Richard Banks [http://www.richard-banks.org] on the Talking Shop Down Under [http://www.talkingshopdownunder.com] podcast about web application security while at “Developer Developer Developer!” in Sydney [http://www.dddsydney.com/]. It’s now online here: Episode 22 - Troy Hunt on Developers and Security [http://www.talkingshopdownunder.com/2010/07/episode-22-troy-hunt-on-developers-and.html] It’s a funny thing, podcasts; there are no second takes...

This content is now available in the Pluralsight course "OWASP Top 10 Web Application Security Risks for ASP.NET" [http://www.pluralsight.com/courses/owasp-top10-aspdotnet-application-security-risks] Authenticating to a website is something most of us probably do multiple times every day. Just looking at my open tabs right now I’ve got Facebook, Stack Overflow, Bit.ly, Hotmail, YouTube and a couple of non-technology forums all active, each one individually authenticated to. In each case I trust...

This content is now available in the Pluralsight course "OWASP Top 10 Web Application Security Risks for ASP.NET" [http://www.pluralsight.com/courses/owasp-top10-aspdotnet-application-security-risks] In the first post of this series [https://www.troyhunt.com/2010/05/owasp-top-10-for-net-developers-part-1.html] I talked about injection and of most relevance for .NET developers, SQL injection. This exploit has some pretty severe consequences but fortunately many of the common practices employed wh...

A report from WhiteHat Security [http://www.slideshare.net/jeremiahgrossman/whitehat-security-8th-website-security-statistics-report] last year reported “83%...
