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
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.

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
Checks: C-24r1_chk

Open Windows Explorer and use the Properties function on each fixed local partition/drive to examine the File System specified on the General Tab. If the File System does not specify NTFS, then this is a finding. Documentable Explanation: Some hardware vendors create a small FAT partition to store troubleshooting and recovery data. No other files should be stored here. This requirement should be documented with the IAO.

Fix: F-53r1_fix

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.

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 Administrator

Checks: C-7892r1_chk

Interview the IAO to ensure that encryption of userid and password information is required, and data is encrypted according to DoD policy. If the user account used for unencrypted remote access within the enclave (premise router) has administrator privileges, then this is a finding. If userid and password information used for remote access to system services from outside the enclave is not encrypted, then this is a finding.

Fix: F-120r1_fix

Encryption of userid and password information is required. Encryption of the user data inside the network firewall is also highly recommended. Encryption of user data coming from or going outside the network firewall is required. Encryption for administrator data is always required.

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”.

Verify firewall exceptions for inbound connections on domain workstations only allow authorized management systems and remote management hosts. Review inbound firewall exception rules in Windows Firewall with Advanced Security. Firewall rules can be complex and should be reviewed with the firewall administrator. One method for restricting inbound connections is to only allow exceptions for a specific scope of remote IP addresses. If allowed inbound exceptions are not limited to authorized management systems and remote management hosts, this is a finding. If a third-party firewall is used, ensure comparable settings are in place.

Ensure firewall exceptions to inbound connections on domain workstations only allow authorized management systems and remote management hosts. Firewall rules can be complex and should be thoroughly tested be applying in a production environment. One method for restricting inbound connections is to only allow exceptions for a specific scope of remote IP addresses. For any inbound rules that allow connections from other systems, configure the Scope for Remote IP address to those of authorized management systems and remote management hosts. This may be defined as an IP address, subnet or range. Apply the rule to all firewall profiles. If a third-party firewall is used, configure inbound exceptions to only include authorized remote management hosts.

If a flaw in an application is exploited while running as a privileged user, the entire system could be compromised. Web browsers and email are common attack vectors for introducing malicious code and must not be run with an administrative user account. Since administrative user accounts may generally change or work around technical restrictions for running a web browser or other applications, it is essential that policy requires administrative users not access the internet or use applications, such as email. The policy should define specific exceptions for local service administration. These exceptions may include HTTP(S)-based tools that are used for the administration of the local system, services, or attached devices.ECSC-1
