Hello ranchers. Hope yall doing great. So I have been trying to figure out the best way to secure a web application and i don't know if to go with Declative or Programatic Security. Anybody care to explain to me the advantages and disadvantages of each. And my other question is, if i choose Form based Authentication, how will i have to add each user that registers on my site manually to the server or are there ways i can use to check the username and password from the database? Please bear with me if this is a stupid question :)
Declarative security is great in that it's already debugged and working and secure, something that can not necessarily be said of whatever you intend to put in place. But it's only the beginning, there's much more to securing a web app than that. Start reading at http://www.coderanch.com/how-to/java/SecurityFaq#web-apps for all the other things you need to do, like preventing SQL injection and XSS attacks. A library like Apache Shiro can do a lot of the things that you'll likely need to do in that respect.
