### Tools for Managing Security

The Application Server provides the following tools for managing security:

- Admin Console, a browser-based tool used to configure security for the entire server, to manage users, groups, and realms, and to perform other system-wide security tasks. For a general introduction to the Admin Console, see Tools for Administration. For an overview of the security tasks you can perform with the Admin Console, see Managing Security With the Admin Console.

- `asadmin`, a command-line tool that performs many of the same tasks as the Admin Console. You may be able to do some things with `asadmin` that you cannot do with Admin Console. You perform `asadmin` commands from either a command prompt or from a script, to automate repetitive tasks. For a general introduction to `asadmin`, see Tools for Administration.

- `deploytool`, a graphical packaging and deployment tool for editing application deployment descriptors to control individual applications’ security. Because `deploytool` is intended for application developers, this document does not describe its use in detail. For instructions on using `deploytool`, see the tool’s online help and The J2EE 1.4 Tutorial at `http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html`.

The Java 2 Platform, Standard Edition (J2SE) provides two tools for managing security:

- `keytool`, a command-line utility for managing digital certificates and key pairs. Use `keytool` to manage users in the `certificate` realm.

- `policytool`, a graphical utility for managing system-wide Java security policies. As an administrator, you will rarely need to use `policytool`.

For more information on using `keytool`, `policytool`, and other Java security tools, see Java 2 SDK Tools and Utilities at `http://java.sun.com/j2se/1.4.2/docs/tooldocs/tools.html#security`.
