NAME ^

Win32::SDDL - Parser for the Windows Security Descriptor Definition Language (SDDL)

VERSION ^

version 0.07

SYNOPSIS ^

    use Win32::SDDL;

    my $sddl = Win32::SDDL->new( 'service' );

    $sddl->Import( 'D:(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPLOCRRC;;;PU)' );

    foreach my $mask( @{$sddl->{ACL}} ){
        $trustees{ $mask->{Trustee} } = 1;
    }

    my @trustees = sort keys %trustees;


    print scalar( @{$sddl->{ACL}} )." entries found.\n";

DESCRIPTION ^

This module was created to aid in interpreting SDDL strings commonly used in Windows to represent access control lists. SDDL stands for Security Descriptor Definition Language. Because SDDL uses many predefined constants, it can be difficult to read. This module provides an object-oriented interface for converting and using the information in SDDL strings.

NOTE: For resources relating to SDDL, see the SEE ALSO section of this document.

METHODS ^

Win32::SDDL->new( *type* );

Example:

    my $sddl = Win32::SDDL->new( 'service' );

Creates a new Win32::SDDL object. Optionally, an object type can be provided. The only optional type supported at present is 'service'. This will change the value of certain constants as they have a different meaning for services than they do for files, registry keys, or other objects.

$sddl->Import( $sddl_string );

Example:

    my $sddl_string = 'D:(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPLOCRRC;;;PU)';

    $sddl->Import( $sddl_string ) or die( "Error!  Unable to import '$sddl_string'!\n" );

PROPERTIES ^

All Win32::SDDL objects have the following properties:

$sddl->{SDString}

The currently loaded SDDL string

$sddl->{Type}

The type of SDDL string (changes the description of some constants).

$sddl->{ACL}

An array of Win32::SDDL::ACE objects.

Each object has the following properties:

Flags

An array of flags translated into English.

AccessMask

An array of permissions translated into English.

Type

The type of ACE (SYSTEM_AUDIT,ACCESS_ALLOW, or ACCESS_DENY).

objectType

A GUID representing the object type for the ACE (usually empty).

InheritedObjectType

A GUID representing the parent object type if it exists.

Trustee

The Trustee name.

UPDATE HISTORY ^

FORTHCOMING CHANGES ^

Modular SID Translation

As originally written, the module uses WMI to translate SIDs to account names. The intention is to allow support for arbitrary translators, with the following to be provided by this module: WMI, native API call, LDAP, Offline.
