<h3>Troubleshoot: Security</h3>
|
||
|
|
<p>Use these resources to determine the cause of problems that occur when using
|
||
|
|
the application server security.</p>
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
<p>Check the application server standard output and standard error log files.
|
||
|
|
See <a href="trblogs.htm">WebSphere Application Server - Express log files</a> for
|
||
|
|
more information.</p>
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<p>When troubleshooting security-related problems, consider the following:</p>
|
||
|
|
<p><strong>Does the problem occur when security is disabled?</strong> <br>
|
||
|
|
The problem may be a result of the enablement of security. More troubleshooting
|
||
|
|
is necessary to ensure the problem is security related. </p>
|
||
|
|
<p><strong>Did security appear to initialize properly?</strong> <br>
|
||
|
|
The following sequence of messages generated in the SystemOut.log indicate
|
||
|
|
normal code initialization of an application server. This varies based
|
||
|
|
on the configuration, but the message are similar: </p>

<p><strong>Is there a stack trace or exception printed in the SystemOut.log?</strong> <br>
|
||
|
|
The stack trace will log any code incorrectly initialized, failing components,
|
||
|
|
and the failing class. </p>
|
||
|
|
<p><strong>Is this a distributed security problem or a local security problem?</strong></p>
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
<p>If the problem is local, the code involved does not make a remote
|
||
|
|
method invocation, then troubleshooting is isolated to a single process.
|
||
|
|
It is important to know when a problem is local or distributed since
|
||
|
|
the behavior of the Object Request Broker (ORB), among other components,
|
||
|
|
is different between the two.</p>
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<p>Once a remote method invocation takes place, a different security
|
||
|
|
code path is entered. When you know the problem involves two or more
|
||
|
|
servers, check the log files of all servers involved. If possible,
|
||
|
|
make sure the timestamps on all machines match as closely as possible
|
||
|
|
to identify request and reply pairs from two different processes easier.</p>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<p><strong>Is the problem related to authentication or authorization?</strong> <br>
|
||
|
|
Most security problems fall under one of these two categories. Authentication
|
||
|
|
is the process of determining who the caller is. Authorization is the
|
||
|
|
process of validating that the caller has the proper authority to invoke
|
||
|
|
the requested method. When authentications fails, typically this is related
|
||
|
|
to either the authentication protocol, authentication mechanism, or user
|
||
|
|
registry. When authorization fails, this is usually related to the application
|
||
|
|
bindings from assembly or deployment and to the identity of the caller
|
||
|
|
who is accessing the method and the roles required by the method. </p>
|
||
|
|
<p><STRONG>Does the problem seem to be related SSL?</STRONG> <br>
|
||
|
|
The Secure Socket Layer (SSL) is a separate layer of security. Troubleshooting
|
||
|
|
SSL is differant than troubleshooting authentication and authorization
|
||
|
|
problems. SSL errors are often caused by incorrect configurations. Each
|
||
|
|
keystore used by a client must contain the certificate of the Certificate
|
||
|
|
Authority (CA) that signed the certificate used by the server. During
|
||
|
|
mutal authentication, the server requires the client to present a cerfticate
|
||
|
|
for authorization. Each server keystore must contain the certificate
|
||
|
|
of the CA that signed the certificate presented by the client. Another
|
||
|
|
common error are configurations where the client and the server do not
|
||
|
|
have common configured SSL cipher suites.</p>
|
||
|
|
<p><strong>Is the problem related to Java 2 Security? </strong> <br>
|
||
|
|
If Java 2 Security is enabled, deployers and administrators are required
|
||
|
|
to make sure that all applications are granted required permissions,
|
||
|
|
otherwise, applications may fail to run.</p>
