I blog about a number of topics here at shiflett.org, and a favorite one is web application security. A reader recently asked for some other security blog recommendations, so I thought I'd mention a few of the ones I try to keep up with.

Although not always the most exciting, Schneier tends to produce a steady stream of relevant content. Here are some others that I've found interesting:

• Andrew van der Stock
• Dan Kuykendall
• Jeremiah Grossman
• Ivan Ristic
• Nitesh Dhanjani
• RSnake
• Ryan Cartner

There is also a blog about Usable Security as well as a Planet Security that aggregates a number of security blogs.
