Puppet Local Security Policy

created by Paul Cannon at email paulscannon at gmail dot com

forked and updated by Adam Yohrling at email aryohrling at gmail dot com

Local_security_policy features

Configure local security policy (LSP) for Windows servers. LSP is key to a baseline configuration of the following security features:

Account Policy

  • Password Policy
  • Account Lockout Policy

Local Policy

  • Audit Policy
  • User Rights Assignment
  • Security Options

This module uses types and providers to list, update, and validate settings.

Use

The title and name of the resources is exact match of what is in Local Security Policy GUI. If you are uncertain of the setting name and values just use puppet resource local_security_policy to pipe them all into a file and make adjustments as necessary. The block will look like this

local_security_policy { 'Audit account logon events': <- Title / Name
  ensure         => present,              <- Always present
  policy_setting => "AuditAccountLogon",  <- The secedit file key. Informational purposes only, not for use in manifest definitions
  policy_type    => "Event Audit",        <- The secedit file section, Informational purposes only, not for use in manifest definitions
  policy_value   => 'Success,Failure',    <- Values
}

How this works

The local_security_policy module works by using secedit /export to export a list of currently set policies. The module will then take the user defined resources and compare the values against the exported policies. If the values on the system do not match the defined resource, the module will run secedit /configure to configure the policy on the system. If the policy already exists on the system no change will be made.

In order to make setting these polices easier, this module uses the policy description from the Local Security Policy management console and translates that into the appropriate entries in the file used by secedit /configure. Similarly, the module is able to translate user and group names into the SID and name values that are used by User Rights Assignment policies.

New policy maps require values for the key, name, and policy_type. Policies that require user and group conversion to SID values require data_type: :principal to perform the translation. Policies that require the value to be enclosed in double-quotes require data_type: :quoted_string. Policies that modify registry values also require a value for reg_type. The following reg_type values are supported:

    REG_NONE 0
    REG_SZ 1
    REG_EXPAND_SZ 2
    REG_BINARY 3
    REG_DWORD 4
    REG_DWORD_LITTLE_ENDIAN 4
    REG_DWORD_BIG_ENDIAN 5
    REG_LINK 6
    REG_MULTI_SZ 7
    REG_RESOURCE_LIST 8
    REG_FULL_RESOURCE_DESCRIPTOR 9
    REG_RESOURCE_REQUIREMENTS_LIST 10
    REG_QWORD 11
    REG_QWORD_LITTLE_ENDIAN 11

Here are examples of working policy definitions from lib\puppet_x\lsp\security_policy.rb: 

'Accounts: Rename administrator account' => {
                name: 'NewAdministratorName',
                policy_type: 'System Access',
                data_type: :quoted_string
            },
 'Recovery console: Allow floppy copy and access to all drives and all folders' => {
                name: 'MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Setup\RecoveryConsole\SetCommand',
                reg_type: '4',
                policy_type: 'Registry Values',
            },
  'Allow log on locally' => {
                name: 'SeInteractiveLogonRight',
                policy_type: 'Privilege Rights',
                data_type: :principal,
      },

In the first example above, the key Accounts: Rename administrator account is what the user will define as the 'name' in the resource. In the policy definitions included in the module, this is the name shown in the Local Security Policy management console. It is recommended to make this something descriptive and easy to remember, or a description pulled from the Operating System. The name 'NewAdministratorName' is the key used in the import file used by secedit /configure. The policy_type 'System Access' is the section name in the import file used by secedit /configure. The data_type ':quoted_string' indicates that this value must be enclosed in double-quotes in the import file used by secedit /configure.

To modify these settings, you would define the following resources in your Puppet configuration:

local_security_policy { 'Accounts: Rename administrator account':
  ensure => present,
  policy_value => 'MyAdminAccount',
}

local_security_policy { 'Recovery console: Allow floppy copy and access to all drives and all folders':
  ensure => present,
  policy_value => '0',
}

local_security_policy { 'Allow log on locally':
  ensure => present,
  policy_value => 'Administrators',
}

Assuming all of the desired values are different than what is currently set in the OS, this would result in the following INI file, which would be imported by secedit /configure:

[Unicode]
Unicode=yes
[System Access]
NewAdministratorName = "MyAdminAccount"
[Registry Values]
MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Setup\RecoveryConsole\SetCommand=4,0
[Privilege Rights]
SeInteractiveLogonRight = *S-1-5-32-544
[Version]
signature="$CHICAGO$"
Revision=1
