# EnterpriseDataProtection CSP
|

|

The EnterpriseDataProtection configuration service provider (CSP) is used to configure Windows Information Protection (WIP) (formerly known as Enterprise Data Protection) specific settings. For more information about WIP, see [Protect your enterprise data using Windows Information Protection (WIP)](https://technet.microsoft.com/itpro/windows/keep-secure/protect-enterprise-data-using-wip).

While WIP has no hard dependency on VPN, for best results you should configure VPN profiles first before you configure the WIP policies. For VPN best practice recommendations, see [VPNv2 CSP](vpnv2-csp.md).

Attack surface reduction rules are supported on Windows Server 2019 as well as Windows 10 clients.
|
||||
|
||||
The limited subset of rules that can be used in Windows 10 Enterprise E3 include:
|
||||
|
||||
- Block executable content from email client and webmail
|
||||
- Block all Office applications from creating child processes
|
||||
- Block Office applications from creating executable content
|
||||
- Block Office applications from injecting code into other processes
|
||||
- Block JavaScript or VBScript from launching downloaded executable content
|
||||
- Block execution of potentially obfuscated scripts
|
||||
- Block Win32 API calls from Office macro
|
||||
- Use advanced protection against ransomware
|
||||
- Block credential stealing from the Windows local security authority subsystem (lsass.exe)
|
||||
- Block process creations originating from PSExec and WMI commands
|
||||
- Block untrusted and unsigned processes that run from USB
|
||||
|
||||

You can exclude files and folders from being evaluated by most attack surface reduction rules. This means that even if an ASR rule determines the file or folder contains malicious behavior, it will not block the file from running. This could potentially allow unsafe files to run and infect your devices.
|
||||
|
||||
> [!WARNING]
|
||||
> [!IMPORTANT]
|
||||
> Excluding files or folders can severely reduce the protection provided by ASR rules. Excluded files will be allowed to run, and no report or event will be recorded.
|
||||
>
|
||||
> If ASR rules are detecting files that you believe shouldn't be detected, you should [use audit mode first to test the rule](evaluate-attack-surface-reduction.md).
|
||||
|
||||
> [!IMPORTANT]
|
||||
> File and folder exclusions do not apply to the following ASR rules:
|
||||
>
|
||||
> * Block process creations originating from PSExec and WMI commands
|
||||
> * Block JavaScript or VBScript from launching downloaded executable content
|
||||
|
||||
You can specify individual files or folders (using folder paths or fully qualified resource names), but you can't specify which rules the exclusions apply to. An exclusion is applied only when the excluded application or service starts. For example, if you add an exclusion for an update service that is already running, the update service will continue to trigger events until the service is stopped and restarted.
