Hello,

Just a quick question because I have done some search in the past and did not 
get anything relevant.

I'm thinking about the possibility of restricting the JBoss AS deployment 
(WAR/EAR/SAR) at the production servers. Basically, it sounds good to have 
JBoss verify the authenticity of WARs dropped in the auto-deploy directory 
prior to deploying anything inside. Otherwise, it is not deployed at all and I 
expect no code inside will be executed at all.

On first strike I thought of JSE SecurityManager, and I know JBoss As can be 
configured to run with a SecurityManager (I have read some of the Wiki entries 
related to this).

However, I'm not too much interested in exercising too much control in specific 
permissions for operations in the webapp. That is too dynamic in nature to 
control it properly. Therefore, what I would like to is simply have JBoss 
verify that a WAR is signed by a trusted signer whose certificate is stored in 
the JBoss keystore, and permit everything inside the WAR provided it passes 
this test.

First off, do you agree this is a good idea and helps raise security? And Is 
this possible, and if so how do I accomplish this?

One counter- case I can think of, is that provided an intruder has access to 
shell, then they can stop JBoss AS or basically modify anything, including 
disabling security manager. Then nothing practical will stop them.

Another question, is there a way to deploy a WAR/EAR/SAR etc. programmatically? 
I heard that auto-deploy is quite resource intensive and I would like to see if 
I can disable it altogether. I already have installed a distributed file 
synchronization mechanism to broadcast file changes periodically over a network 
of servers, so I can deploy updated WARs likewise onto the local filesystem of 
individual servers. The remaining is have JBoss verify the WAR and deploy it.

Thanks for any insights in advance.
