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 do not provide individual accountability for system access and resource usage.System AdministratorInformation Assurance Officer

Checks: C-7885r1_chk

Interview the SA to determine if any shared accounts exist. Any shared account must be documented with the IAO. Documentation should 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. Note: As an example, a shared account may be permitted for a help desk or a site security personnel machine, if that machine is stand-alone and has no access to the network.

Fix: F-33r1_fix

Remove any shared accounts that do not meet the exception requirements listed.

Antivirus programs are a primary line of defense against the introduction of viruses and malicious code that can destroy data and even render a computer inoperable. Utilizing an antivirus program provides the ability to detect malicious code before extensive damage occurs. Updated virus scan data files help to protect a system, since new malware are identified by the software vendors on a continual basis.If another recognized antivirus product is installed and has a current signature, this would still be a finding; however, the severity may be reduced to a CAT III.System Administrator

Checks: C-61983r2_chk

If V-19910 from an antivirus STIG has been applied to the system, the signature verification portion of this requirement is NA. Verify a supported DoD antivirus product has been installed on the system. If McAfee VirusScan Enterprise 8.8 or later is not installed on the system, this is a finding. And If a product other than McAfee VirusScan Enterprise is used and V-19910 from an antivirus STIG has not been applied to the system, verify the date of the antivirus signature. If the antivirus program signature has not been updated within the past 7 days, this is a finding. The version numbers and the date of the signature can generally be checked by starting the antivirus program. The information may appear in the antivirus window or be available in the Help >> About window. The location varies from product to product.

Fix: F-66879r1_fix

Install McAfee VirusScan Enterprise 8.8 or later on the system. Update the signature file at least every 7 days.

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

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.

This is a category 1 finding because the ability to set access permissions and audit critical directories and files is only available by using the NTFS file system. The capability to assign access permissions to file objects is a DOD policy requirement. The FAT file system only provides the capability to make files read-only and hidden. The capability to change these attributes is not restricted to any users. An unauthorized individual could boot the machine from a floppy disk and gain full and unrecorded access to file data. trueSystem AdministratorInformation Assurance Officer

A system is more vulnerable to unauthorized access when system users recycle the same password several times without being required to change a password to a unique password on a regularly scheduled basis. This enables users to effectively negate the purpose of mandating periodic password changes. The default value is 24 for Windows domain systems. DoD has decided this is the appropriate value for all Windows systems.System Administrator

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.

The registry is a database for computer configuration information, much of which is sensitive. An attacker could use this to facilitate unauthorized activities.

DCOM calls are executed under the security context of the calling user by default.

If present, the RunAs value tells the COM Service Control Manager (SCM) the name of the account under which the server is to be activated. In addition to the account name, the COM SCM must also have the password of the account. The result of a successful logon is a security context (token) for the named account that is used as the primary token for the new COM server process.

Setting application accounts to expire may cause applications to stop functioning. The site will have a policy that application account passwords manually generated and entered by a system administrator are changed at least annually or when a system administrator with knowledge of the password leaves the organization. Application/service account passwords will be at least 15 characters and follow complexity requirements for all passwords.System AdministratorInformation Assurance Officer

Checks: C-11762r1_chk

The site should have a local policy to ensure that passwords for application/service accounts are at least 15 characters in length and meet complexity requirements for all passwords. Application/service account passwords manually generated and entered by a system administrator must be changed at least annually or whenever a system administrator that has knowledge of the password leaves the organization. Interview the system administrators on their policy for application/service accounts. If it does not meet the above requirements, this is a finding. Using the DUMPSEC utility: Select “Dump Users as Table” from the “Report” menu. Select the available fields in the following sequence, and click on the “Add” button for each entry: UserName SID PswdRequired PswdExpires PswdLastSetTime LastLogonTime AcctDisabled Groups If any application accounts listed in the Dumpsec user report have a date older than one year in the “PwsdLastSetTime” column, then this is a finding. Note: The following command can be used on Windows 2003/2008 Active Directory if DumpSec cannot be run: Open a Command Prompt. Enter “Dsquery user -limit 0 -o rdn -stalepwd 365”. This will return a list of User Accounts with passwords older the one year.

Fix: F-13613r1_fix

Analyze the system using the Security Configuration and Analysis snap-in. Expand the Security Configuration and Analysis tree view. Navigate to Local Policies -> User Rights Assignment. If any user accounts, or groups, (to include administrators) are granted the “Debug programs” right, then this is a finding. If Administrators require this right for troubleshooting or application issues, it should be assigned on a temporary basis as needed. Documentable Explanation: Some applications may require this right to function such as the Windows 2003 Cluster service account. Any exception needs to be documented with the IAO. Acceptable forms of documentation include vendor published documents and application owner confirmation.
