Concrete5 Server hardening guide
I thing this can be a good value to Concrete5 project because I'm developing other projects that require Magento and I was very pleased to see a very well done detailed installation guide with best practices.
I hope we can grow this topic and thank you very much.
Security is what I do for a living. I specialize in web application security, vulnerability analysis and pen testing. Currently I maintain three C5 sites and have multiple test servers at home.
Having this sort of discusson open to the public is great for soliciting input, however it's obviously not a good idea to discuss real or potential vulnerabilites, attack vectors and so forth in a forum that's open the world.
