| /** |
| * 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. |

| * otherwise have access to.</td> |

| * <td>The ability to get the cookie handler that processes highly |
| * security sensitive cookie information for an Http session.</td> |

| * highly security sensitive cookie information. Some web servers |

| * hosts and ports on internal networks, which could then become |
| * targets for attack.</td> |

| * could access security sensitive information.</td> |

| * code can set an authenticator that monitors and steals user |
| * authentication input as it retrieves the input from the user.</td> |

| * <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> |

| * traffic to an arbitrary network host.</td> |

| * <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> |
