Description

• 

This routine is used to update and retrieve the current security settings. Security settings can only be modified when security is disabled. Changes to security settings are lost on restart.

  

This routine returns the current security settings (prior to the call) as an expression sequence of equations of the form name = val. Here, name is a recognized security setting name and val is, depending on the name, either a boolean or a list of file specifications.

  

If the settings argument is provided, each name = val pair is applied to the current settings, replacing the previous value.

• 

Valid names are:

SECURE_READ_LIST

specification list for permitted read operations

SECURE_NOREAD_LIST

specification list for restricted read operations

SECURE_WRITE_LIST

specification list for permitted write operations

SECURE_NOWRITE_LIST

specification list for restricted write operations

SECURE_EXTCALL_LIST

specification list for permitted external call libraries

SECURE_NOEXTCALL_LIST

specification list for restricted external call libraries

SECURE_SYSCALL_ENABLED

Boolean flag for enabling/disabling calls to system and ssystem

SECURE_MODE

Boolean flag for enabling/disabling security

For any given list of file specifications, if a list item is one of the names SECURE_READ_LIST, SECURE_NOREAD_LIST, SECURE_WRITE_LIST, SECURE_NOWRITE_LIST, SECURE_EXTCALL_LIST, or SECURE_NOEXTCALL_LIST, then the list item is replaced by the current value of that name in the security settings.
