/**
 * 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.*" and "*" signify a wildcard
 * match, while "*foo" and "a*b" do not.
 * <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.
 *
 * <table class="striped">

 * <tr>
 *   <th scope="row">allowHttpTrace</th>
 *   <td>The ability to use the HTTP TRACE method in HttpURLConnection.</td>

 *   information in the HTTP headers (such as cookies) that it might not
 *   otherwise have access to.</td>

 *   <th scope="row">getCookieHandler</th>
 *   <td>The ability to get the cookie handler that processes highly
 *   security sensitive cookie information for an Http session.</td>
 *   <td>Malicious code can get a cookie handler to obtain access to
 *   highly security sensitive cookie information. Some web servers
 *   use cookies to save user private information such as access

 *   <th scope="row">getProxySelector</th>
 *   <td>The ability to get the proxy selector used to make decisions
 *   on which proxies to use when making network connections.</td>
 *   <td>Malicious code can get a ProxySelector to discover proxy
 *   hosts and ports on internal networks, which could then become
 *   targets for attack.</td>

 *   could access security sensitive information.</td>

 *   a password</td>

 * <tr>
 *   <th scope="row">setCookieHandler</th>
 *   <td>The ability to set the cookie handler that processes highly
 *   security sensitive cookie information for an Http session.</td>

 *
 * <tr>
 *   <th scope="row">setDefaultAuthenticator</th>
 *   <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>
 *   <th scope="row">setProxySelector</th>
 *   <td>The ability to set the proxy selector used to make decisions
 *   on which proxies to use when making network connections.</td>
 *   <td>Malicious code can set a ProxySelector that directs network
 *   traffic to an arbitrary network host.</td>
 * </tr>
 *
 * <tr>
 *   <th scope="row">setResponseCache</th>
 *   <td>The ability to set the response cache that provides access to
 *   a local response cache.</td>
 *   <td>Malicious code getting access to the local response cache
 *   could access security sensitive information, or create false
 *   entries in the response cache.</td>
 *   </tr>
 *
 * <tr>
 *   <th scope="row">specifyStreamHandler</th>
 *   <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>
