ServletRequest Attributes

I'm reorganizing my JSPs and would like to implement a Servlet that I have that authenticates my users. After authenticated, I'd like to use the RequestDispatcher to go to a JSP page. From that JSP page, I need to be able to check whether or not the user was authenticated and I was thinking of using the request attributes. Is this approach secure? Can a hacker add attributes to the request, or can this only be done from within my servlet?

Scoped variables in the various scopes are safe from hackers. Anything is possible with enough determination, but it'd take hacking into the server to make such mischief...

With regards to your plan: frequently a servlet filter is used to check for authentication, and authentication information is usually stored in the session.
