The Windows 7 Security Technical Implementation Guide (STIG) is published as a tool to improve the security of Department of Defense (DoD) information systems. The requirements were developed from DoD consensus, as well as the Windows 7 Security Guide and security templates published by Microsoft Corporation. Comments or proposed revisions to this document should be sent via e-mail to the following address: disa.stig_spt@mail.mil.

Inadequate physical protection can undermine all other security precautions utilized to protect the system. This can jeopardize the confidentiality, availability, and integrity of the system. Physical security of the AIS is the first line protection of any system.System AdministratorInformation Assurance Officer
Checks: C-7883r1_chk

Interview the SA to determine if equipment is located in an access controlled area. Note: Servers will be located in rooms, or locked cabinets, that are accessible only to authorized systems personnel. Authorized user access should be verified at two points (i.e. building access and server room). User workstations containing sensitive data should be in access controlled areas.

Fix: F-31r1_fix

Relocate equipment to a controlled access area.

Shared accounts (accounts where two or more people log on with the same user identification) do not provide adequate identification and authentication. There is no way to provide for non-repudiation or individual accountability for system access and resource usage.System AdministratorInformation Assurance Officer
Checks: C-62049r2_chk

Determine if any shared accounts exist. If no shared accounts exist, this is NA. Any shared account must be documented with the ISSO. Documentation must include the reason for the account, who has access to this account, and how the risk of using a shared account (which provides no individual identification and accountability) is mitigated. If such documentation does not exist, or is not current, this is a finding. Note: As an example, a shared account may be permitted for a help desk or a site security personnel machine, if that machine is standalone and has no access to the network.

Fix: F-66947r1_fix

Create or update shared accounts documentation that minimally contains the name of the shared account(s), the system(s) on which the accounts exist, and the individuals who have access to the accounts. Remove any shared accounts that do not meet the requirements.

Run "winver.exe". If the "About Windows" dialog box does not display the following version or greater, this is a finding. "Microsoft Windows Version 6.1 (Build 7601: Service Pack 1)" No Release Candidates or Beta versions will be used in a production environment. The initial release of Windows 7 is unsupported as of 9 April 2013. Systems must be updated to Service Pack 1.

Fix: F-30098r4_fix

Update the system to a version of the operating system supported by the vendor. Support for Windows 2008/2008 R2 ended 14 January 2020. After this date, systems must have Windows 2012 or greater installed.

Recovery of a damaged or compromised system in a timely basis is difficult without a system information backup. A system backup will usually include sensitive information such as user accounts that could be used in an attack. As a valuable system resource, the system backup should be protected and stored in a physically secure location.System AdministratorInformation Assurance Officer
Checks: C-7887r1_chk

Interview the SA to determine if system recovery backup procedures are in place that comply with DoD requirements. Any of the following would be a finding: •The site does not maintain emergency system recovery data. •The emergency system recovery data is not protected from destruction and stored in a locked storage container. •The emergency system recovery data has not been updated following the last system modification.

Fix: F-36r1_fix

Maintaining an audit trail of system activity logs can help identify configuration errors, troubleshoot service disruptions, and analyze compromises that have occurred, as well as detect attacks. Audit logs are necessary to provide a trail of evidence in case the system or network is compromised. Event logs may be susceptible to tampering if proper permissions are not applied.System AdministratorInformation Assurance Officer

This feature is provided for system availability reasons, such as the user's machine being disconnected from the network or domain controllers being unavailable.

Inappropriate granting of user rights can provide system, administrative, and other high level capabilities. The "Deny access to this computer from the network" right defines the accounts that are prevented from logging on from the network. In an Active Directory Domain, denying logons to the Enterprise Admins and Domain Admins groups on lower trust systems helps mitigate the risk of privilege escalation from credential theft attacks which could lead to the compromise of an entire domain. Local accounts on domain-joined systems must also be assigned this right to decrease the risk of lateral movement resulting from credential theft attacks.

The following would not be a finding: The referenced registry values do not exist. "Type" has a value of "NoSync" or "NT5DS". "Type" has a value of "NTP" or "Allsync" AND the "NTPServer" is blank or configured to an authorized time server. For DoD organizations, the US Naval Observatory operates stratum 1 time servers, identified at http://tycho.usno.navy.mil/ntp.html. Time synchronization will occur through a hierarchy of time servers down to the local level. Clients and lower level servers will synchronize with an authorized time server in the hierarchy. Domain joined systems are automatically configured to synchronize with domain controllers and would not be a finding unless this is changed.

Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\Kerberos\Parameters\ Value Name: SupportedEncryptionTypes Type: REG_DWORD The values are determined by the selection of encryption suites in the policy "Network Security: Configure encryption types allowed for Kerberos". Due to the various possible combinations, it is not possible to include all acceptable values as viewed directly in the registry. The value must be converted to binary to determine configuration of specific bits. This will determine whether this is a finding. Note the value for the registry key. For example when all suites, including the DES suites are selected, the value will be "0x7fffffff (2147483647)". Open the Windows calculator (Run/Search for "calc"). Select "View", then "Programmer". Select "Dword" and either "Hex" or "Dec". Enter the appropriate form of the value found for the registry key (e.g., Hex - enter 0x7fffffff, Dec - enter 2147483647). Select "Bin". The returned value may vary in length, up to 32 characters. If either of the 2 right most characters are "1", this is a finding.
