Windows Schannel Cookbook
A cookbook to configure the windows Secure Channel (Schannel) security support provider (SSP). This SSP contains a set of security protocols and ciphers suites commonly used for HTTPS communications. Many of the microsoft provided services and 3rd party software make use of Schannel for their communication so by removing support for a given protocol, removes it for all components.
This can be a double-edge sword, restricting a protocol might be fine for one service and end up breaking another.
Always make sure you test these settings before deploying into production as you could end up shooting yourself in the foot
Using this cookbook should help improve your security posture for the following microsoft services and help towards meeting regulatory compliance (PCI CIS FIPS)
- Internet Information Services (IIS)
- Microsoft Remote Desktop (RDP) when configured to use TLS
- LDAPS (Active Directory)
- Global Catalog SSL (Active Directory)
- WinRM/HTTPS (Windows Remote Management)
TODO : Insert image of external scan before and after.
Support for managing the following
- Transport Layer Security (TLS) - v1.0, v1.1, v1.2
- Secure Socket Layer (SSL) - v2.0, v3.0
- Private Communications Technology (PCT) - v1.0
- NULL, DES, RC2, RC4, 3DES, AES
- MD5, SHA
- Diffie-Hellman (DH)
- Windows Server 2008 (R1, R2)
- Windows Server 2012 (R1, R2)
falsechanges made to protocols won't take affect until after a restart, this doesn't apply to ciphers and hashes. The default is false change this to true to initiate a reboot after the run.
Other than the
allow_reboot attribute all the others are controlled by either setting it to either
this is CaSe Sensitive

windows_schannel Cookbook CHANGELOG
This file is used to list changes made in each version of the windows_schannel cookbook.
0.1.2 - (17-06-2016)
- Fixed some typo's in the README ready for relase to the supermarket.
- Changed the attribute values to make it easier to read rather than 1 or 0, means it is now caSe sensitive but I think its worth the trade off as its easier to interpret
- Added support for Hashes (MD5 and SHA) and Keyexchanges (DH)
- Refactored the ciphers to loop based on foodcritic
- Added reboot notifier for protocol changes.
- Building the framework of the cookbook.
