PCI compliance requires quarterly scans from a PCI compliance vendor. Hostek.com goes above and beyond this requirement by having regular scans from two different PCI compliance vendors. One vendor's scans are done quarterly. The other's scans are done nightly. This ensures that all potential PCI compliance issues are accurately identified and dealt with promptly.

Datacenter

The data center where the hostek.com equipment is housed maintains SSAE 16 Certification (audit report). This replaced the SAS 70 Type 2 Certification.

SSL/TLS Protocol Initialization Vector Implementation Information Disclosure

aka: BEAST (Browser Exploit Against SSL/TLS) Vulnerability

NOTE: If you are on a shared server or a managed VPS, please submit a support ticket [1] and attach/include your PCI scan report. The information below is for our non managed VPS customers.

• Place the following text in a file named TLS.reg and execute the file. It will add registry values to enable TLS 1.1 and TLS 1.2 support:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\Schannel\Protocols\TLS 1.1]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\Schannel\Protocols\TLS 1.1\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\Schannel\Protocols\TLS 1.1\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\Schannel\Protocols\TLS 1.2]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\Schannel\Protocols\TLS 1.2\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\Schannel\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

• After completing the above step, go to Start -> Run -> (type gpedit.msc) -> (click OK)
• Navigate to Computer Configuration -> Administrative Template -> Network -> SSL Configuration Settings
• Right click on SSL Cipher Suite Order and choose Edit (Windows 2008 R2) or Properties (Windows 2008)
• Select Enabled and replace the text in the textbox under SSL Cipher Suites(not to be confused with the Notes textbox) with the following long line of text(All on a single line - no line breaks or spaces):

TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256_P256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256_P384,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256_P521,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384_P256,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384_P384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384_P521,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256_P256,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256_P384,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256_P521,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384_P384,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384_P521,TLS_DHE_DSS_WITH_AES_128_CBC_SHA256,TLS_DHE_DSS_WITH_AES_256_CBC_SHA256,TLS_RSA_WITH_NULL_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256_P256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256_P384,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256_P521,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384_P384,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384_P521,TLS_RSA_WITH_RC4_128_SHA,TLS_RSA_WITH_RC4_128_MD5,SSL_CK_RC4_128_WITH_MD5,TLS_RSA_WITH_NULL_SHA,TLS_RSA_WITH_NULL_MD5

• Click OK
• Reboot server

Disable SSLv2 & Strong Cyphers Only & Strong Protocols Only

If you are on a shared server, please open a support ticket and attach the PCI scan report.

For VPS's: This generally applies to a Windows based server. If you see one of these items on your PCI scan report, download this zip [2] and extract the appropriate .reg file and put that on your VPS and double click it to make the appropriate registry change to fix the issue. Generally if one of these show on your report, we suggest running all three .reg files to fully take care of the issue at one time.

NOTE: You will need to reboot the server for these changes to take affect.

VPS-Windows 2008 Servers

This free tool can be used to determine if vulnerable or weak protocols or cypers are enabled, and provides the option to disable them.

Changes using this tool require a server reboot to complete them.
