/**
* This class is for various network permissions.
* A NetPermission contains a name (also referred to as a "target name") but
* no actions list; you either have the named permission
* or you don't.
* <P>
* The target name is the name of the network permission (see below). The naming
* convention follows the hierarchical property naming convention.
* Also, an asterisk
* may appear at the end of the name, following a ".", or by itself, to
* signify a wildcard match. For example: "foo.*" or "*" is valid,
* "*foo" or "a*b" is not valid.
* <P>
* The following table lists all the possible NetPermission target names,
* and for each provides a description of what the permission allows
* and a discussion of the risks of granting code the permission.
* <P>
*
* <table border=1 cellpadding=5 summary="Permission target name, what the permission allows, and associated risks">
* <tr>
* <th>Permission Target Name</th>
* <th>What the Permission Allows</th>
* <th>Risks of Allowing this Permission</th>
* </tr>
*
* <tr>
* <td>setDefaultAuthenticator</td>
* <td>The ability to set the
* way authentication information is retrieved when
* a proxy or HTTP server asks for authentication</td>
* <td>Malicious
* code can set an authenticator that monitors and steals user
* authentication input as it retrieves the input from the user.</td>
* </tr>
*
* <tr>
* <td>requestPasswordAuthentication</td>
* <td>The ability
* to ask the authenticator registered with the system for
* a password</td>
* <td>Malicious code may steal this password.</td>
* </tr>
*
* <tr>
* <td>specifyStreamHandler</td>
* <td>The ability
* to specify a stream handler when constructing a URL</td>
* <td>Malicious code may create a URL with resources that it would
normally not have access to (like file:/foo/fum/), specifying a
stream handler that gets the actual bytes from someplace it does
have access to. Thus it might be able to trick the system into
creating a ProtectionDomain/CodeSource for a class even though
that class really didn't come from that location.</td>
