import java.security.Permission;

/**
 * A {@code SecurityManager} that always permits an action to take place. By default a Java application has no
 * {@code SecurityManager} set (although Java applets do). This security manager acts as if there was no security
 * manager in place. matlabcontrol uses Remote Method Invocation (RMI) to communicate with MATLAB when it is used in an
 * application that is not running inside MATLAB. RMI requires a security manager be set in order to allow loading
 * classes that are defined in the other Java Virtual Machine, but not its own. This is for good reason, because
 * allowing arbitrary code to be loaded into an application has the potential for a security exploit. By default RMI
 * allows connections from any external machine unless otherwise configured (or blocked by a firewall). matlabcontrol
 * is configured to prohibit any external connections on the port it is using.
 * 


 * When matlabcontrol launches a session of MATLAB it installs this security manager so that MATLAB may load classes
 * defined in your application. matlabcontrol does not install this security manager in your program. Installing any
 * security manager will allow your application to receive objects from MATLAB that are of classes defined in MATLAB,
 * but not in your application. Using this security manager is convenient when your application does not need any
 * security beyond the default of having no security manager installed.
 * 


 * To install this security manager:
 *  * {@code
 * System.setSecurityManager(new PermissiveSecurityManager());
 * }
 * 
 * 
 * @since 4.0.0
