/**
 * This class provides a mechanism for specified named permissions
 * related to the Java security framework.  These permissions have no
 * associated actions list.  They are either granted or not granted.
 *
 * <p>The list of valid permission names is:<br>
 * <table border=1>
 * <tr><th>Permission Name</th><th>Permission Allows</th><th>Risks</th</tr>
 * <tr>
 *   <td><code>createAccessControlContext</code></td>
 *   <td>Allows creation of an AccessControlContext</td>
 *   <td>The new control context can have a rogue DomainCombiner, leading
 *       to a privacy leak</td></tr>
 * <tr>
 *   <td><code>getDomainCombiner</code></td>
 *   <td>Get a DomainCombiner from an AccessControlContext</td>
 *   <td>Access to a DomainCombiner can lead to a privacy leak</td></tr>
 * <tr>
 *   <td><code>getPolicy</code></td>
 *   <td>Allows retrieval of the system security policy</td>
 *   <td>Malicious code can use information from the policy to better plan
 *       an attack</td></tr>
 * <tr>
 *   <td><code>setPolicy</code></td>
 *   <td>Allows the security policy to be changed</td>
 *   <td>Malicious code can give itself any permission it wants</td></tr>
 * <tr>
 *   <td><code>getProperty.</code><em>key</em></td>
 *   <td>Retrieve the property specified by the key</td>
 *   <td>Malicious code can use information from the property to better plan
 *       an attack</td></tr>
 * <tr>
 *   <td><code>setProperty.</code><em>key</em></td>
 *   <td>Allows changing of the value of all properties implied by key</td>
 *   <td>Malicious code can insert rogue classes to steal keys or recreate
 *       the security policy with whatever permissions it desires</td></tr>
 * <tr>
 *   <td><code>insertProvider.</code><em>key</em></td>
 *   <td>Allows the named provider to be added</td>
 *   <td>Malicious code can insert rogue providers that steal data</td></tr>
 * <tr>
 *   <td><code>removeProvider.</code><em>key</em></td>
 *   <td>Allows the named provider to be removed</td>
 *   <td>A missing provider can cripple code that relies on it</td></tr>
 * <tr>
 *   <td><code>setSystemScope</code></td>
 *   <td>Allows the system identity scope to be set</td>
 *   <td>Malicious code can add certificates not available in the original
 *       identity scope, to gain more permissions</td></tr>
 * <tr>
 *   <td><code>setIdentityPublicKey</code></td>
 *   <td>Allows the public key of an Identity to be set</td>
 *   <td>Malicious code can install its own key to gain permissions not
 *       allowed by the original identity scope</td></tr>
 * <tr>
 *   <td><code>SetIdentityInfo</code></td>
 *   <td>Allows the description of an Identity to be set</td>
 *   <td>Malicious code can spoof users into trusting a fake identity</td></tr>
 * <tr>
 *   <td><code>addIdentityCertificate</code></td>
 *   <td>Allows a certificate to be set for the public key of an identity</td>
 *   <td>The public key can become trusted to a wider audience than originally
 *       intended</td></tr>
 * <tr>
 *   <td><code>removeIdentityCertificate</code></td>
 *   <td>Allows removal of a certificate from an identity's public key</td>
 *   <td>The public key can become less trusted than it should be</td></tr>
 * <tr>
 *   <td><code>printIdentity</code></td>
 *   <td>View the name of the identity and scope, and whether they are
 *       trusted</td>
 *   <td>The scope may include a filename, which provides an entry point for
 *       further security breaches</td></tr>
 * <tr>
 *   <td><code>clearProviderProperties.</code><em>key</em></td>
 *   <td>Allows the properties of the named provider to be cleared</td>
 *   <td>This can disable parts of the program which depend on finding the
 *       provider</td></tr>
 * <tr>
 *   <td><code>putProviderProperty.</code><em>key</em></td>
 *   <td>Allows the properties of the named provider to be changed</td>
 *   <td>Malicious code can replace the implementation of a provider</td></tr>
 * <tr>
 *   <td><code>removeProviderProperty.</code><em>key</em></td>
 *   <td>Allows the properties of the named provider to be deleted</td>
 *   <td>This can disable parts of the program which depend on finding the
 *       provider</td></tr>
 * <tr>
 *   <td><code>getSignerPrivateKey</code></td>
 *   <td>Allows the retrieval of the private key for a signer</td>
 *   <td>Anyone that can access the private key can claim to be the
 *       Signer</td></tr>
 * <tr>
 *   <td><code>setSignerKeyPair</code></td>
 *   <td>Allows the public and private key of a Signer to be changed</td>
 *   <td>The replacement might be a weaker encryption, or the attacker
 *       can use knowledge of the replaced key to decrypt an entire
 *       communication session</td></tr>
 * </table>
 *
 * <p>There is some degree of security risk in granting any of these
 * permissions. Some of them can completely compromise system security.
 * Please exercise extreme caution in granting these permissions.
