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 is the first line of protection of any system.PECF-1

Checks: C-44752r1_chk

Verify user workstations containing sensitive data are in access-controlled areas. Users must maintain control of, and protect, mobile systems. If systems are not adequately protected, this is a finding.

Fix: F-41152r1_fix

Establish site policy that ensures workstations containing sensitive data are located inside a controlled access area. Establish a policy on protecting mobile systems outside of controlled areas.

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. Documentation must include a list of personnel that have access to each shared account.IAGA-1

Checks: C-44753r3_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-41153r1_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 Category III.ECVP-1

Checks: C-61987r2_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 Patch 3 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-66883r1_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 manner 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 must be protected and stored in a physically secure location.CODB-1

Checks: C-44757r2_chk

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-41157r1_fix

Implement system recovery procedures that include maintaining emergency system recovery data, protecting that data from destruction and storing it in a locked storage container, and updating it following each and every system modification.

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. Collecting this data is essential for analyzing the security of information assets and detecting signs of suspicious and unexpected behavior. Handle Manipulation auditing under Object Access is needed to correctly enable the recording of events related to the access and changing of files and directories. Auditing must also be enabled on the specific file system objects to be audited.ECAR-2, ECAR-3

Several user rights on domain systems require that local administrator accounts be assigned to them. This is separate from the built-in Administrators group, which also contains domain administrative accounts/groups. Defining a consistent group name allows compliance to be more easily determined.ECLP-1

Checks: C-58041r2_chk

This requirement is NA for non domain-joined systems. *This requirement may be satisfied by the existence of the new built-in security groups "Local account" or "Local account and member of Administrators group". Execute the following PowerShell commands to determine if the new built-in security groups exist on the system: $SID = New-Object System.Security.Principal.SecurityIdentifier ("S-1-5-113") $Account = $SID.Translate([System.Security.Principal.NTAccount]) $Account.Value If the group exists, "NT Authority\Local account" will be returned. (Using SID S-1-5-114 will return "NT Authority\Local account and member of Administrators group".) If the built-in groups exist, this is not a finding. If the built-in groups do not exist on the system, review local groups defined on the system. Documentation and scripts supporting the creation of this group to restrict local administrative accounts were changed at one point. The original name, "DeniedNetworkAccess", was changed to "DenyNetworkAccess". If the group "DenyNetworkAccess" or "DeniedNetworkAccess" does not exist, this is a finding. Compare the membership of the defined group with the local Administrators group. Verify the group includes all local administrator accounts as members. This includes the built-in Administrator account. It does not include domain administrative accounts or groups. If the group "DenyNetworkAccess" or "DeniedNetworkAccess" does not include all local administrator accounts, this is a finding. *Windows 8.1 and Windows Server 2012 R2 added new built-in security groups, "Local account" and "Local account and member of Administrators group", for assigning permissions and rights to local accounts. Microsoft Security Advisory Patch 2871997 adds these groups to Windows 7, Windows 8, Windows Server 2008 R2, and Windows Server 2012.
