| Review the SharePoint server configuration to ensure FIPS-validated cryptography is employed to protect unclassified information. Open MMC. Click File, Add/Remove Snap-in, and add Group Policy Object Editor. Enter a name for the Group Policy Object, or accept the default. Click Finish. Click OK. Navigate to Computer Policy, Computer Configuration, Administrative Templates, Network, and SSL Configuration settings. Right-click SSL Configuration Settings, click SSL Cipher Suite Order, and then click Edit. In the SSL Cipher Suite Order dialog box, if "Enabled" is not selected, this is a finding. Under Options, in the SSL Cipher Suites text box, verify the following text is displayed: TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_3DES_EDE_CBC_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA_P256,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA_P384,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA_P521,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA_P256,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA_P384,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA_P521,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA_P256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA_P384,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA_P521,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P256,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P521,TLS_DHE_DSS_WITH_AES_128_CBC_SHA,TLS_DHE_DSS_WITH_AES_256_CBC_SHA,TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA,SSL_CK_DES_192_EDE3_CBC_WITH_MD5,TLS_RSA_WITH_NULL_MD5 Click OK. If any ciphers other than those listed above are present, this is a finding. |

| Configure SharePoint to employ FIPS-validated cryptography to protect unclassified information. Open MMC. Click “File”, “Add/Remove Snap-in”, and “add Group Policy Object Editor”. Enter a name for the Group Policy Object, or accept the default. Click “Finish”. Click “OK”. Navigate to Computer Policy >> Computer Configuration >> Administrative Templates >> Network >> SSL Configuration settings. Right-click “SSL Configuration Settings”, click “SSL Cipher Suite Order”, and then click “Edit”. In the “SSL Cipher Suite Order” dialog box, select "Enabled" option. Under “Options”, in the “SSL Cipher Suites” text box, delete everything, and then copy and paste from the following text: TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_3DES_EDE_CBC_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA_P256,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA_P384,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA_P521,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA_P256,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA_P384,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA_P521,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA_P256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA_P384,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA_P521,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P256,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P521,TLS_DHE_DSS_WITH_AES_128_CBC_SHA,TLS_DHE_DSS_WITH_AES_256_CBC_SHA,TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA,SSL_CK_DES_192_EDE3_CBC_WITH_MD5,TLS_RSA_WITH_NULL_MD5 Click “OK”. |
