// moving the question with more info from haskell-cafe to web-devel

Hallo,

I already wrote a message with the same subject to haskell-cafe without reply.

I did not found anything comparable to Spring Security[1][2] (Java) or Symfony
Security[3] (PHP) in Haskell. Both components are used in web applications to
grant or deny access to resources based on roles, ACLs or custom voters.

[1] http://projects.spring.io/spring-security
[2] http://docs.spring.io/autorepo/docs/spring-security/3.1.7.RELEASE/apidocs
[3]
http://api.symfony.com/master/Symfony/Component/Security/Core/SecurityContext.html

A naive strategy would be to port the concepts of both components, which are
very similar, to Haskell. They represent a lot of accumulated knowledge from
many experts about web security.

Or are there better ways to do web security in a powerful language like
Haskell?

There was some unfinished role-based-access-control effort in snap[4] that has
been removed from git now.

There seem to be a more modern (and more complex) thing than Role-Based-
Access-Control now, XACML[5] which is used inside Red Hats JBoss[6].
