Security Level Indicators

When you set up a session security options data structure, you must use the CodeVerifierOptions type to specify which Java code should be run through the verifier before execution. The verifier checks to see that the Java code is valid and that it does not attempt any illegal actions that could affect the host platform.

enum CodeVerifierOptions {
   eDontCheckCode = 0, 
   eCheckRemoteCode, 
   eCheckAllCode 
   };

Constant descriptions

eDontCheckCode

Don't verify any code.

eCheckRemoteCode

Verify any code that is read from a network.

eCheckAllCode

Verify all code.

In addition, you must also use the NetworkSecurityOptions type to specify the security level allowed for applets accessing a network.

enum NetworkSecurityOptions {
   eNoNetworkAccess = 0, 
   eAppletHostAccess, 
   eUnrestrictedAccess
   };

Constant descriptions

eNoNetworkAccess

Applets have no access to networks.

eAppletHostAccess

An applet may access only its host server.

eUnrestrictedAccess

Applets have unrestricted access to all networks.

Finally you must use the FileSystemOptions type to specify the security level allowed for applets accessing the local file system.

enum FileSystemOptions {
   eNoFSAccess = 0,
   eLocalAppletAccess,
   eAllFSAccess
};

Constant descriptions

eNoFSAccess

Applets have no access to the local file system.

eLocalAppletAccess

Only applets that are stored locally may access the local file system.

eAllFSAccess

All applets have access to the local file system.

See "Session Security Options Structure" (page 45) for more information about using these three security indicator types.
