Discussion

V-102613

medium

A known vulnerability in Windows could allow the execution of malicious code by either opening a compromised document or viewing it in the Windows Preview pane.

Organizations must disable the Windows Preview pane and Windows Detail pane.

V-1070

medium

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.

V-1072

medium

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.

V-1073

high

Systems at unsupported service packs or releases will not receive security updates for new vulnerabilities and leaves them subject to exploitation. Systems must be maintained at a service pack level supported by the vendor with new security updates.

V-1074

high

Malicious software can establish a base on individual desktops and servers. Employing an automated mechanism to detect this type of software will aid in elimination of the software from the operating system.

V-1075

low

Preventing display of the shutdown button in the logon dialog box may encourage a hard shut down with the power button. (However, displaying the shutdown button may allow individuals to shut down a system anonymously.)

V-1076

low

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.

V-1077

medium

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. Event logs may be susceptible to tampering if proper permissions are not applied.

V-1081

high

The ability to set access permissions and auditing is critical to maintaining the security and proper access controls of a system. To support this, volumes must be formatted using the NTFS file system.

V-1084

low

This check verifies that Windows is configured to not wipe clean the system pagefile during a controlled system shutdown.

V-1085

low

This check verifies that Windows is configured to not limit access to floppy drives when a user is logged on locally.

V-1089

medium

Failure to display the logon banner prior to a logon attempt will negate legal proceedings resulting from unauthorized access to system resources.

V-1090

low

The default Windows configuration caches the last logon credentials for users who log on interactively to a system. This feature is provided for system availability reasons, such as the user's machine being disconnected from the network or domain controllers being unavailable. Even though the credential cache is well-protected, if a system is attacked, an unauthorized individual may isolate the password to a domain user account using a password-cracking program and gain access to the domain.

V-1093

high

Allowing anonymous logon users (null session connections) to list all account names and enumerate all shared resources can provide a map of potential points to attack the system.

V-1097

medium

The account lockout feature, when enabled, prevents brute-force password attacks on the system. The higher this value is, the less effective the account lockout feature will be in protecting the local system. The number of bad logon attempts must be reasonably small to minimize the possibility of a successful password attack, while allowing for honest errors made during a normal user logon.

V-1098

medium

The account lockout feature, when enabled, prevents brute-force password attacks on the system. This parameter specifies the period of time that must pass after failed logon attempts before the counter is reset to "0". The smaller this value is, the less effective the account lockout feature will be in protecting the local system.

V-1099

medium

The account lockout feature, when enabled, prevents brute-force password attacks on the system. This parameter specifies the amount of time that an account will remain locked after the specified number of failed logon attempts.

V-1102

high

Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities.

Accounts with the "Act as part of the operating system" user right can assume the identity of any user and gain access to resources that user is authorized to access. Any accounts with this right can take complete control of a system.

V-1104

medium

The longer passwords are in use, the greater the opportunity for someone to gain unauthorized knowledge of them. Scheduled changing of passwords hinders the ability of unauthorized users to crack passwords and gain access to a system.

V-1105

medium

Permitting passwords to be changed in immediate succession within the same day allows users to cycle passwords through their history database. This enables users to effectively negate the purpose of mandating periodic password changes.

V-1107

medium

A system is more vulnerable to unauthorized access when users can recycle the same password several times without being required to change it to a unique password on a regularly scheduled basis. This enables users to effectively negate the purpose of mandating periodic password changes. The default value is 24 for Windows domain systems. DoD has decided this is the appropriate value for all Windows systems.

V-1112

low

Outdated or unused accounts provide penetration points that may go undetected. Inactive accounts must be deleted if no longer necessary or, if still required, disable until needed.

V-1113

medium

A system faces an increased vulnerability threat if the built-in guest account is not disabled. This account is a known account that exists on all Windows systems and cannot be deleted. This account is initialized during the installation of the operating system with no password assigned.

V-1114

medium

The built-in guest account is a well-known user account on all Windows systems and, as initially installed, does not require a password. This can allow access to system resources by unauthorized users. Renaming this account to an unidentified name improves the protection of this account and the system.

V-1115

medium

The built-in administrator account is a well-known account subject to attack. Renaming this account to an unidentified name improves the protection of this account and the system.

V-1119

medium

Allowing other operating systems to run on a secure system, can allow users to circumvent security. If more than one operating system is installed on a computer, each must be configured to be compliant with STIG guidance.

V-1122

medium

Unattended systems are susceptible to unauthorized use and must be locked when unattended. Enabling a password-protected screen saver to engage after a specified period of time helps protects critical and sensitive data from exposure to unauthorized personnel with physical access to the computer.

V-1127

high

An account that does not have Administrator duties must not have Administrator rights. Such rights would allow the account to bypass or modify required security restrictions on that machine and make it vulnerable to attack.

System administrators must log on to systems only using accounts with the minimum level of authority necessary.

For domain-joined workstations, the Domain Admins group must be replaced by a domain workstation administrator group (see V-36434 in the Active Directory Domain STIG). Restricting highly privileged accounts from the local Administrators group helps mitigate the risk of privilege escalation resulting from credential theft attacks.

Systems dedicated to the management of Active Directory (AD admin platforms, see V-36436 in the Active Directory Domain STIG) are exempt from this. AD admin platforms may use the Domain Admins group or a domain administrative group created specifically for AD admin platforms (see V-43711 in the Active Directory Domain STIG).

Standard user accounts must not be members of the built-in Administrators group.

V-1128

low

Security configuration tools (such as Security Templates and Group Policy) allow system administrators to consolidate all security related system settings into a single configuration file. These settings can then be applied consistently to any number of Windows machines.

V-1130

medium

Changing the system's file and directory permissions allows the possibility of unauthorized and anonymous modification to the operating system and installed applications.

V-1135

low

Improperly configured share permissions on printers can permit the addition of unauthorized print devices on the network. Windows shares are a means by which files, folders, printers, and other resources can be published for network users to remotely access.

V-1136

low

Users should not be permitted to remain logged on to the network after they have exceeded their permitted logon hours. In many cases, this indicates that a user forgot to log off before leaving for the day. However, it may also indicate that a user is attempting unauthorized access at a time when the system may be less closely monitored. Forcibly disconnecting users when logon hours expire protects critical and sensitive network data from exposure to unauthorized personnel with physical access to the computer.

V-1140

high

Using a privileged account to perform routine functions makes the computer vulnerable to malicious software inadvertently introduced during a session that has been granted full privileges. The rule of least privilege must always be enforced.

V-1141

medium

Some non-Microsoft SMB servers only support unencrypted (plain text) password authentication. Sending plain text passwords across the network, when authenticating to an SMB server, reduces the overall security of the environment. Check with the vendor of the SMB server to see if there is a way to support encrypted password authentication.

V-1145

medium

Allowing a system to automatically log on when the machine is booted could give access to any unauthorized individual who restarts the computer. Automatic logon with administrator privileges would give full access to an unauthorized individual.

V-1148

low

To minimize potential points of attack, local users, other than built-in accounts such as Administrator and Guest accounts, should not exist on a workstation in a domain. Users must always log onto workstations in a domain with their domain accounts.

V-1150

medium

The use of complex passwords increases their strength against attack. The built-in Windows password complexity policy requires passwords to contain at least 3 of the 4 types of characters (numbers, upper- and lower-case letters, and special characters), as well as preventing the inclusion of user names or parts of.

V-1151

low

The print spooler allows users to add and to delete printer drivers on the local system. This capability must be restricted to privileged groups to ensure only stable, non-malicious drivers are used.

V-1152

high

The registry is integral to the function, security, and stability of the Windows system. Some processes may require anonymous access to the registry. This must be limited to properly protect the system.

V-1153

high

The Kerberos v5 authentication protocol is the default for authentication for domains. NTLM which is less secure, is retained in later Windows versions for compatibility with standalone systems as well as applications that may still use it. Earlier versions of the LM/NTLM protocol are particularly vulnerable to attack and must be prevented.

V-1154

medium

Disabling the Ctrl+Alt+Del security attention sequence can compromise system security. Because only Windows responds to the Ctrl+Alt+Del security sequence, you can be assured that any passwords you enter following that sequence are sent only to Windows. If you eliminate the sequence requirement, malicious programs can request and receive your Windows password. Disabling this sequence also suppresses a custom logon banner.

V-1155

medium

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.

Local accounts on domain-joined systems must also be assigned this right to decrease the risk of lateral movement resulting from credential theft attacks.

The Guests group must be assigned this right to prevent unauthenticated access.

V-1157

medium

Unattended systems are susceptible to unauthorized use and must be locked. Configuring a system to lock when a smart card is removed will ensure the system is inaccessible when unattended.

V-1162

medium

If this policy is enabled, it causes the Windows Server Message Block (SMB) server to perform SMB packet signing.

V-1163

medium

Requests sent on the secure channel are authenticated and sensitive information (such as passwords) is encrypted, but not all information is encrypted. If this policy is enabled, outgoing secure channel traffic should be encrypted.

V-1164

medium

Requests sent on the secure channel are authenticated, and sensitive information (such as passwords) is encrypted, but the channel is not integrity checked. If this policy is enabled, all outgoing secure channel traffic should be signed.

V-1165

low

Computer account passwords are changed automatically on a regular basis. Enabling this policy to disable automatic password changes can make the system more vulnerable to malicious access. Frequent password changes can be a significant safeguard for your system. If this policy is disabled, a new password for the computer account will be generated every 30 days.

V-1166

medium

If this policy is enabled, it causes the Windows Server Message Block (SMB) client to perform SMB packet signing when communicating with an SMB server that is enabled or required to perform SMB packet signing.

V-1168

medium

Backup Operators are able to read and write to any file in the system, regardless of the rights assigned to it. Backup and restore rights permit users to circumvent the file access restrictions present on NTFS disk drives for backup and restore purposes. Members of the Backup Operators group must have separate logon accounts for performing backup duties.

V-1171

medium

Removable hard drives can be formatted and ejected by others who are not members of the Administrators Group, if they are not properly configured. Formatting and ejecting removable NTFS media should only be done by administrators.

V-1172

low

This setting configures the system to display a warning to users telling them how many days are left before their password expires. By giving the user advanced warning, the user has time to construct a sufficiently strong password.

V-1173

low

Windows system maintains a global list of shared system resources such as DOS device names, mutexes, and semaphores. Each type of object is created with a default DACL that specifies who can access the objects with what permissions. If this policy is enabled, the default DACL is stronger, allowing non-admin users to read shared objects, but not modify shared objects that they did not create.

V-1174

low

Open sessions can increase the avenues of attack on a system. This setting is used to control when a computer disconnects an inactive SMB session. If client activity resumes, the session is automatically re-established. This protects critical and sensitive network data from exposure to unauthorized personnel with physical access to the computer.

V-11806

low

The user name of the last user to log onto a system will not be displayed. This eliminates half of the userid/password equation that an unauthorized person would need to log on.

V-14224

medium

The built-in administrator account, as a well known account subject to attack, is disabled by default and per STIG requirements. Domain administrative accounts on domain-joined systems should provide sufficient availability for administering a system. A site with limited administrators must ensure they have a contingency for administering a non-domain system.

V-14225

medium

The longer a password is in use, the greater the opportunity for someone to gain unauthorized knowledge of the passwords. Passwords for the built-in administrator account and any emergency administrator accounts must be changed at least annually or when any member of the administrative team leaves the organization.

V-14228

medium

This setting prevents the system from setting up a default system access control list for certain system objects, which could create a very large number of security events, filling the security log in Windows and making it difficult to identify actual issues.

V-14229

medium

medium

This setting configures the elevation requirements for logged on administrators to complete a task that requires raised privileges.

V-14236

medium

User Account Control (UAC) is a security mechanism for limiting the elevation of privileges, including administrative accounts, unless authorized. Denying elevation requests from standard user accounts requires tasks that need elevation to be initiated by accounts with administrative privileges. This prevents privileged account credentials from being cached with standard user profile information to help mitigate credential theft.

This is a Category 1 finding because of the potential for gaining unauthorized system access.

Pipes are internal system communications processes. They are identified internally by ID numbers that vary between systems. To make access to these processes easier, these pipes are given names that do not vary between systems.

When this setting is disabled, network shares can be accessed by any network user. This could lead to the exposure or corruption of sensitive data.

This setting configures Windows to restrict anonymous access to only those shares and pipes listed in "Network Access: Named Pipes that can be accessed anonymously".

Information systems not protected with strong password schemes (including passwords of minimum length) provide the opportunity for anyone to crack the password, thus, gaining access to the system and causing the device, information, or the local network to be compromised.

Passwords that do not expire increase exposure with a greater probability of being discovered or cracked.

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.

When the WDigest Authentication protocol is enabled, plain text passwords are stored in the Local Security Authority Subsystem Service (LSASS) exposing them to theft. This setting will prevent WDigest from storing credentials in memory.

SMBv1 is a legacy protocol that uses the MD5 algorithm as part of SMB. MD5 is known to be vulnerable to a number of attacks such as collision and preimage attacks as well as not being FIPS compliant.

Disabling SMBv1 support may prevent access to file or print sharing resources with systems or devices that only support SMBv1. File shares and print services hosted on Windows Server 2003 are an example, however Windows Server 2003 is no longer a supported operating system. Some older network attached devices may only support SMBv1.

Accounts or groups given rights on a system may show up as unresolved SIDs for various reasons including deletion of the accounts or groups. If the account or group objects are reanimated, there is a potential they may still have rights no longer intended. Valid domain accounts or groups may also show up as unresolved SIDs if a connection to the domain cannot be established for some reason.
