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.

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 OfficerIAGA-1

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.

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 AdministratorECVP-1

Checks: C-61985r2_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-66881r1_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 OfficerCODB-1

Autoplay begins reading from a drive as soon as you insert media in the drive. As a result, the setup file of programs and the music on audio media starts immediately. By default, autoplay is disabled on removable drives, such as the floppy disk drive (but not the CD-ROM drive) and on network drives. If you enable this policy, you can also disable autoplay on all drives.HKHKSystem AdministratorECSC-1
