System cryptography: Use FIPS compliant algorithms for encryption, hashing and signing

Description

This security setting determines if the Transport Layer Security/Secure Sockets Layer (TL/SS) Security Provider supports only the TLS_RSA_WITH_3DES_EDE_CBC_SHA cipher suite. In effect, this means that the provider only supports the Transport Layer Security (TLS) protocol as a client and as a server (if applicable). It uses only the Triple DES encryption algorithm for the TLS traffic encryption, only the Rivest, Shamir, and Adleman (RSA) public key algorithm for the TLS key exchange and authentication, and only the Secure Hashing Algorithm 1 (SHA-1) for the TLS hashing requirements.

For Encrypting File System Service (EFS), it supports only the Triple Data Encryption Standard (DES) encryption algorithm for encrypting file data supported by the NTFS file system. By default, EFS uses the Advanced Encryption Standard (AES) algorithm with a 256-bit key in the Windows Server 2003 family and DESX algorithm in Windows XP for encrypting file data. For information about EFS, see Encrypting File System.

For Terminal Services, it supports only the Triple DES encryption algorithm for encrypting terminal services network communication. For information about Terminal Services, see Terminal Services.

Default: Disabled.

Configuring this security setting

You can configure this security setting by opening the appropriate policy and expanding the console tree as such: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\

For specific instructions about how to configure security policy settings, see Edit security settings on a Group Policy object.

Note

  • The Federal Information Processing Standard (FIPS) 140-1 is a security implementation designed for certifying cryptographic software. FIPS 140-1 validated software is required by the U.S. Government and requested by other prominent institutions.
