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.

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

This is a Category 1 finding because Virus scan 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 the most current virus scan program provides the ability to detect this malicious code before extensive damage occurs. Updated virus scan data files can help protect a system, because new viruses are identified by the software vendors on a monthly basis.The scripts check for McAfee and Symantec Antivirus, corporate and client editions. Due to variation of installations, manual checks may be required for verifying Anti-Virus compliance.E-Mail versions of anti-virus software are not acceptable as protection for Windows operating systems. However, both the E-Mail anti-virus software and the operating system anti-virus software can coexist and run on the same system.trueSystem AdministratorECVP-1
Checks: C-519r1_chk

Note: The Gold Disk checks for McAfee and Symantec Antivirus, corporate and client editions. Due to variation of installations, manual checks may be required for verifying antivirus compliance. V0019910 has been added as part of the Desktop STIG Update which specifically looks at McAfee and Symantec AV signature files. If you have these programs, address them with that requirement and mark this one as N/A. If none of the following products are installed and supported at an appropriate maintenance level, then this is a finding: Symantec Antivirus at the following level is not installed: Corporate Edition Version 9.0.6 or higher Corporate Edition Version 10.x or higher Endpoint Protection Version 11.0 or higher McAfee’s Antivirus Version 8.0 or higher is not installed. And The antivirus signature file is out of date. If the anti virus program signature file is not dated within the past 7 days, then this is a finding. Note: The version numbers and the date of the signature file can generally be checked by starting the antivirus program from the toolbar icon or from the Start menu. The information may appear in the antivirus window or be available in the Help > About window. The location varies from product to product. Note: E-mail versions of antivirus software are not acceptable as protection for Windows operating systems. However, both the e-mail antivirus software and the operating system antivirus software can coexist and run on the same system. Documentable Explanation: If a recognized antivirus product, such as Innoculator or another product is installed and has a current signature file, then this would still be a finding, but the severity code should be reduced to a Category III.

Fix: F-5817r1_fix

Configure the system with supported, DoD-approved virus scanning software. Ensure the signature file is current.

Improper modification of the core system files can render a system inoperable. Further, modifications to these system files can have a significant impact on the security configuration of the system. Auditing of significant modifications made to the system files provides a method of determining the responsible party.Automated checking sometimes reports this as a false finding. If a manual review of a questionable finding shows auditing to be set correctly, then this would not be a finding.System AdministratorECAR-1, ECAR-2, ECAR-3
Checks: C-23r1_chk

If system-level auditing is not enabled, or if the system and data partitions are not installed on NTFS partitions, then mark this as a finding. Open Windows Explorer and use the file and folder properties function to verify that the audit settings on each partition/drive is configured to audit all "failures" for the "Everyone" group.

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 OfficerECCD-1, ECCD-2

The Security Event Log contains information on security exceptions that occur on the system. This data is critical for identifying security vulnerabilities and intrusions. The Application and System logs can also contain information that is critical in assessing security events. Therefore, these logs must be protected from unauthorized access and modification. An Auditors group will be used to restrict access to auditing through the User Right “Manage auditing and security log” (V-1103) and for assigning permissions to event logs (V-1077).
