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.

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 Officer

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.

Major software vendors release security patches and hot fixes to their products when security vulnerabilities are discovered. It is essential that these updates be applied in a timely manner to prevent unauthorized persons from exploiting identified vulnerabilities. The severity code may be elevated to a Category I if patches deemed Critical have not been applied.If any of the patches not installed are Microsoft ‘Critical’, then this should be elevated to a Category 1.System AdministratorInformation Assurance Officer

Severity Override: If any of the patches not installed are Microsoft ‘Critical’, then the category code should be elevated to ‘1’. Note: If a penetration scan has been run on the network, it will report findings if security-related updates are not applied. Then, this check may be marked as “Not Applicable”. Some applications (such as DMS and GCSS) use a system release process to keep systems current. If this is the case, then these systems should be at the current release.

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.

Utilizing a whitelist provides a configuration management method for allowing the execution of only authorized software. Using only authorized software decreases risk by limiting the number of potential vulnerabilities. The organization must identify authorized software programs and only permit execution of authorized software. The process used to identify software programs that are authorized to execute on organizational information systems is commonly referred to as whitelisting.

Checks: C-69247r2_chk

This is applicable to unclassified systems, for other systems this is NA. Verify the operating system employs a deny-all, permit-by-exception policy to allow the execution of authorized software programs. If an application whitelisting program is not in use on the system, this is a finding. Configuration of whitelisting applications will vary by the program. AppLocker is a whitelisting application built into Windows 7 Enterprise. A deny-by-default implementation is initiated by enabling any AppLocker rules within a category, only allowing what is specified by defined rules. If AppLocker is used, perform the following to view the configuration of AppLocker: Open PowerShell. If the AppLocker PowerShell module has not been previously imported, execute the following first: Import-Module AppLocker Execute the following command, substituting [c:\temp\file.xml] with a location and file name appropriate for the system: Get-AppLockerPolicy -Effective -XML > c:\temp\file.xml This will produce an xml file with the effective settings that can be viewed in a browser or opened in a program such as Excel for review. Implementation guidance for AppLocker is available in the NSA paper "Application Whitelisting using Microsoft AppLocker" under the Microsoft Windows section of the following link: https://www.nsa.gov/ia/mitigation_guidance/security_configuration_guides/operating_systems.shtml

Attackers are constantly looking for vulnerabilities in systems and applications. Data Execution Prevention (DEP) prevents harmful code from running in protected memory locations reserved for Windows and other programs.

Checks: C-69313r3_chk

If DEP is configured through the Enhanced Mitigation Experience Toolkit (EMET) (V-36705), this is NA. Verify the DEP configuration. Open a command prompt (cmd.exe) or PowerShell with elevated privileges (Run as administrator). Enter "BCDEdit /enum {current}". (If using PowerShell "{current}" must be enclosed in quotes.) If the value for "nx" is not "OptOut", this is a finding. (The more restrictive configuration of "AlwaysOn" would not be a finding.)

Fix: F-75015r1_fix

Configure DEP to at least OptOut. Open a command prompt (cmd.exe) or PowerShell with elevated privileges (Run as administrator). Enter "BCDEDIT /set {current} nx OptOut". (If using PowerShell "{current}" must be enclosed in quotes.) "AlwaysOn", a more restrictive selection, is also valid but does not allow applications that do not function properly to be opted out of DEP. Note: Suspend BitLocker before making changes to the DEP configuration. Opted out exceptions can be configured in the "System Properties". Open "System" in Control Panel. Select "Advanced system settings". Click "Settings" in the "Performance" section. Select the "Data Execution Prevention" tab. Applications that are opted out are configured in the window below the selection "Turn on DEP for all programs and services except those I select:".

If a client device supports simultaneous use of wireless and wired connections, then this increases the probability that an adversary who can access the device using its wireless interface can then route traffic through the device’s wired interface to attack devices on the wired network or obtain sensitive DoD information.

Checks: C-72767r1_chk

This is NA for systems that do not have wireless network adapters. Disabling of wired network adapters can be accomplished through various means. Third-party software that manages this is the most reliable solution. Some network adapters may have a configuration option to address this locally. At minimum, the organization must have a policy that users turn off wireless network adapters when connected to a wired network. If wireless network adapters are not turned off when the system is connected to a wired network, this is a finding.
