color:#1F497D'>BK> Disagree that click jacking is limited to browsers. It
affects browsers because it’s rendered from css and web pages have
flexible layout. I have seen click jacking with forms by using full
transparency. This is a bit of an issue for me as it is very likely that
the UI I will be using will be rendered ( prob using Moonlight from Xaml)
, the same rules apply its just a bit more tricky as it the security interacts
with the rendering engine.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Clickjacking requires the attacker be able to overlay a powerful
UI view rendered transparent over a view of the attacker’s
choosing. That means the attacker needs a way to name and display the
powerful view. If displaying that page requires a capability the attacker
doesn’t have, the attack fails. Of course, if the attacker has the
capability to the page, the attack is unnecessary.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>For a standard browser I can agree with you but im not user
here.. since we are displaying rendered windows in a browser though I suppose
if there are no security pop ups then click jacking becomes useless. <o:p></o:p></span></p>

color:#1F497D'>BK> It’s the interaction with ACL systems and how
to manage if say you have a Directory Server , A Capability File Server and
Older NT File Server (Acl) , Machines running Windows 7 , Macs and
machines running a new Capability OS. How do you interact the
capabilities ? I’m not designing a Research system but
a practical one. Windows allows you to add Domain groups to local groups
eg you can add Domain Admins to Administrator and Domain Users to Users and all
domain users can the login with User or Admin rights. How do you model
that any user in the organization can log in get basic rights from the
tree , deploy his allocated applications from the tree and access his files on
the server. I seem to always need this user –Group mapping is there a
nicer way .. I need to rethink.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Yeah im getting more confident here whether you store all the
ACLs in the tree or provide a power box to map cap lists to groups is something
that can be decide later. <o:p></o:p></span></p>

relies on another user. <o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I don’t know what you mean by “another
user.” There are many mechanisms to enforce VOC. For example,
the user’s capability can point to a proxy for the resource, and the
proxy will block “mistakes,” i.e., delegations that would violate
policy.<o:p></o:p></span></p>
