SecurityMetrics to validate annual PCI Compliance requirement
We are receiving a failed “Compliance from Security metrics for which we have always pasted for the last 3 years. Nothing has changed that we are arware of and they have listed
Details are:
ISP: Comcast - WashingtonDC.hfc.comcastbu siness.net
OS: SBS 2011 – Fully patched and up to date
Network: Single Static IP and Single-site Domain
Router was provided by their VOIP group:
Edgewater Networks
The test was initiated from a Workstation running Win-7 Pro with Symantec Endpoint running.
I’m not sure if they are failing up because HTTPS is enabled or if I’m just reading the results wrong.
Has anyone seen this and does anyone know of a solution that will not affect the SBS 2011 functions pertaining to the phones and remote access.
THE RESULTS THAT THEY LISTED ARE:
PCI Compliance: Fail
Scan Target: -Our-Static Ip Address - WashingtonDC.hfc.comcastbu siness.net
Scan ID: 4310329
Start: 2012-09-07 13:45:53

TCP/IP Fingerprint OS Estimate: Microsoft Windows Server 2008 Beta 3
Description: SSL/TLS Protocol Initialization Vector Implementation Information Disclosure Vulnerability Synoposis: It may be possible to obtain sensitive information from the remote host with SSL/TLS-enabled services. Impact: A vulnerability exists in SSL 3.0 and TLS 1.0 that could allow information disclosure if an attacker intercepts encrypted traffic served from an affected system. TLS 1.1, TLS 1.2, and all cipher suites that do not use CBC mode are not affected. This script tries to establish an SSL/TLS remote connection using an affected SSL version and cipher suite, and then solicits return data. If returned application data is not fragmented with an empty or one-byte record, it is likely vulnerable. OpenSSL uses empty fragments as a countermeasure unless the 'SSL_OP_DONT_INSERT_EMPTY_ FRAGMENTS' option is specified when OpenSSL is initialized. Microsoft implemented one-byte fragments as a countermeasure, and the setting can be controlled via the registry key H KEY_LOCAL_MACHINE\\System\ \CurrentCo ntrolSet\\ Control\\S ecurityPro viders \\SCHANNEL\\SendExtraRecor d. Therefore, if multiple applications use the same SSL/TLS implementation, some may be vulnerable while others may not, depending on whether or not a countermeasure has been enabled. Note that this script detects the vulnerability in the SSLv3/TLSv1 protocol implemented in the server. It does not detect the BEAST attack where it exploits the vulnerability at HTTPS client-side (i.e., Internet browser). The detection at server-side does not necessarily mean your server is vulnerable to the BEAST attack because the attack exploits the vulnerability at client-side, and both SSL/TLS clients and servers can independently employ the split record countermeasure.

Resolution: Configure SSL/TLS servers to only use TLS 1.1 or TLS 1.2 if supported. Configure SSL/TLS servers to only support cipher suites that do not use block ciphers. Apply patches if available. Note that additional configuration may be required after the installation of the MS12-006 security update in order to enable the split-record countermeasure. See http://support.microsoft.com/kb/2643584 for details. Risk Factor: Medium/ CVSS2 Base Score: 4.3 (AV:N/AC:M/Au:N/C:P/I:N/A: N) CVE: CVE-2011-3389\
