OWASP ZAP is an excellent (FREE) tool to test your website for common security issues. It has a large library of plugins and an what seems to be an active community. Although the tool has an active attack method, I prefer the passive attack method as you can use the site as you normally would. Although tutorials do exist on how to get started, I personally had difficulty finding them or knowing what I was even looking for when I first started. Especially related to passive security scanning. The interface isn't the most "intuitive", so I figured I would write these instructions for anybody encountering the same problems.
I'm currently working through a complete Identity setup without using Entity framework. This is taking me to difficult places as the source for this library is yet to be released. It involves lots of reading and guessing. One area of confusion is the Security Stamp.

Because the Internet is still the wild west (as it should be), I run FireFox in a mode that I recommend. This can decrease page load times, reduce bandwidth usage and reduce the tracking that can be done (not prevent it). Click on through to see the screen shots…
Database, Database, Database. They are everywhere, and have been for a long time. Personally I find working with a database enjoyable, especially when the requirements get twisted and you need to expand your mind to solve the problem. This blog post is not about one of those mind-bending situations. Just some basics that help with everyday SQL. This one is actually dated now, but still not used as much as it probably should be.
