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.HKSystem Administrator

This is a Category 1 finding because it allows anonymous logon users (null session connections) to list all account names and enumerate all shared resources, thus providing a map of potential points to attack the system. By default, Windows allows anonymous users to list account names and enumerate share names.trueIn a mixed Windows environment, this setting may cause systems with down-level operating systems to fail to authenticate, may prevent their users from changing their passwords, and may cause problems with managing printers and spools. In domains supporting Exchange 2003 servers and versions of Outlook earlier than Outlook 2003, the setting “Network access: Do not allow anonymous enumeration of SAM accounts and shares” should be set to “Disabled” on the Domain Controller Group Policy to allow Outlook to anonymously query the global catalog service.System AdministratorInformation Assurance Officer

In Kerberos, there are 2 types of tickets: Ticket Granting Tickets (TGTs) and Service Tickets. Kerberos tickets have a limited lifetime so the time an attacker has to implement an attack is limited. This policy controls how long TGTs can be renewed. With Kerberos, the user’s initial authentication to the domain controller results in a TGT which is then used to request Service Tickets to resources. Upon startup, each computer gets a TGT before requesting a service ticket to the domain controller and any other computers it needs to access. For services that startup under a specified user account, users must always get a TGT first, then get Service Tickets to all computers and services accessed. System Administrator

This is a category 1 finding because when unencrypted access to system services is permitted, an intruder can intercept user identification and passwords that are being transmitted in clear text. This could give an intruder unlimited access to the network.Information Assurance Officer
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-29048r1_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. Refer to the Enclave Security STIG section on “FTP and Telnet” for detailed information on its use.

Unsigned network traffic is susceptible to man-in-the-middle attacks where an intruder captures packets between the server and the client and modifies them before forwarding them to the client. In the case of an LDAP server, this means that an attacker can cause a client to make decisions based on false records from the LDAP directory. You can lower the risk of an attacker pulling this off in a corporate network by implementing strong physical security measures to protect the network infrastructure. Furthermore, implementing Internet Protocol security (IPSec) authentication header mode (AH), which performs mutual authentication and packet integrity for Internet Protocol (IP) traffic, can make all types of man-in-the-middle attacks extremely difficult.trueHKSystem AdministratorECSC-1

The POSIX subsystem is an Institute of Electrical and Electronic Engineers (IEEE) standard that defines a set of operating system services. The POSIX Subsystem is required if the server supports applications that use that subsystem. The subsystem introduces a security risk relating to processes that can potentially persist across logins. That is, if a user starts a process and then logs out, there is a potential that the next user who logs in to the system could access the previous users process. This is dangerous because the process started by the first user may retain that users system privileges; anything the second user does with that process will be performed with the privileges of the first user. trueHKSystem Administrator

When directory service data files, especially for directories used for identification, authentication, or authorization, reside on the same logical partition as user-owned files, the directory service data may be more vulnerable to unauthorized access or other availability compromises. Directory service and user-owned data files sharing a partition may be configured with less restrictive permissions in order to allow access to the user data. The directory service may be vulnerable to a denial of service attack when user-owned files on a common partition are expanded to an extent preventing the directory service from acquiring more space for directory or audit data.System Administrator
Checks: C-48684r2_chk

Refer to the AD database location obtained in check V-8316. Note the logical drive (e.g., C:) on which the files are located. Determine if the server is currently providing file sharing services to users with the following command. Enter "net share" at a command prompt. Note the logical drive(s) or file system partition for any site-created data shares. Ignore all system shares (e.g., Windows NETLOGON, SYSVOL, and administrative shares ending in $). User shares that are hidden (ending with $) should not be ignored. If user shares are located on the same logical partition as the directory server data files, this is a finding.

When a directory service using multi-master replication (such as AD) executes on computers that do not have synchronized time, directory data may be corrupted or updated invalidly. The lack of synchronized time could lead to audit log data that is misleading, inconclusive, or unusable. In cases of intrusion, this may invalidate the audit data as a source of forensic evidence in an incident investigation. In AD, the lack of synchronized time could prevent clients from logging on or accessing server resources as a result of Kerberos requirements related to time variance.System Administrator
Checks: C-48687r3_chk

Determine if a time synchronization tool has been implemented on the Windows domain controller. If the Windows Time Service is used, verify the following registry values. If they are not configured as specified, this is a finding. Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \System\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient\ Value Name: Enabled Type: REG_DWORD Value: 1 Registry Path: \System\CurrentControlSet\Services\W32Time\Parameters\ Value Name: Type Type: REG_SZ Value: NT5DS (preferred), NTP, or Allsync If these Windows checks indicate a finding because the NtpClient is not enabled, determine if an alternate time synchronization tool is installed and enabled. If the Windows Time Service is not enabled and no alternate tool is enabled, this is a finding.

Executing application servers on the same host machine with a directory server may substantially weaken the security of the directory server. Web or database server applications usually require the addition of many programs and accounts increasing the attack surface of the computer. Some applications require the addition of privileged accounts providing potential sources of compromise. Some applications (such as MS Exchange) may require the use of network ports or services conflicting with the directory server. In this case, non-standard ports might be selected and this could interfere with intrusion detection or prevention services.System Administrator
Checks: C-48690r2_chk

Review the roles and services the domain controller is running. Run "services.msc" to display the Services console. Determine if any running services are application components. Examples of services indicating the presence of applications are: -DHCP Server for DHCP server -IIS Admin Service for IIS web server -Microsoft Exchange System Attendant for Exchange -MSSQLServer for SQL Server. If any application-related components have the "Started" status, this is a finding. Installed roles can be displayed by viewing Server Roles in the Add (or Remove) Roles and Features wizard. (Cancel before any changes are made.) Determine if any additional server roles are installed. A basic domain controller set up will include the following: -Active Directory Domain Services -DNS Server If any roles not requiring installation on a domain controller are installed, this is a finding. Supplemental Notes: A Domain Name System (DNS) server integrated with the directory server (e.g., AD-integrated DNS) is an acceptable application. However, the DNS server must comply with the DNS STIG security requirements. Some directory servers utilize specialized web servers for administrative functions and databases for data management. These web and database servers are permitted as long as they are dedicated to directory server support and only administrative users have access to them.

Allowing anonymous access to the root DSE data on a directory server provides potential attackers with a number of details about the configuration and data contents of a directory. For example, the namingContexts attribute indicates the directory space contained in the directory; the supportedLDAPVersion attribute indicates which versions of the LDAP protocol the server supports; and the supportedSASLMechanisms attribute indicates the names of supported authentication mechanisms. An attacker with this information may be able to select more precisely targeted attack tools or higher value targets. The following network controls allow the finding severity to be downgraded to not a finding since these measures lower the risk associated with anonymous access. Network hardware ports at the site are subject to 802.1x authentication or MAC address restrictions.

Checks: C-46917r1_chk

At this time, this is a finding for all Windows domain controllers for sensitive or classified levels as Windows Active Directory Domain Services (AD DS) does not provide a method to restrict anonymous access to the root DSE on domain controllers. The following can be used to verify anonymous access if allowed. Open a command prompt (not elevated). Run "ldp.exe". From the Connection menu, select Bind. Select Simple bind for the Bind type. Clear the User, Password, and Domain fields, Click OK. RootDSE attributes should display, such as various namingContexts.

To the extent that anonymous access to directory data (outside the root DSE) is permitted, read access control of the data is effectively disabled. If other means of controlling access (such as, network restrictions) are compromised, there may be nothing else to protect the confidentiality of sensitive directory data. The following network controls allow the finding severity to be downgraded to a CAT II since these measures lower the risk associated with anonymous access. Network hardware ports at the site are subject to 802.1x authentication or MAC address restrictions.

Confirmation of anonymous access will be displayed at the end: res = ldap_simple_bind_s Authenticated as: 'NT AUTHORITY\ANONYMOUS LOGON' From the Browse menu, select Search. In the Search dialog, enter the DN of the domain naming context (generally something like "dc=disaost,dc=mil") in the Base DN field. Clear the Attributes field and select Run. Error messages should display related to binds and user not authenticated. If attribute data is displayed, anonymous access is enabled to the domain naming context and this is a finding.

Fix: F-45051r1_fix

Configure directory data (outside the root DSE) of a non-public directory to prevent anonymous access. For AD, there are multiple configuration items that could enable anonymous access. Changing the access permissions on the domain naming context object (from the secure defaults) could enable anonymous access. If the check procedures indicate this is the cause, the process that was used to change the permissions should be reversed. This could have been through the Windows Support Tools ADSI Edit console (adsiedit.msc). The dsHeuristics option is used. This is addressed in check V-8555 in the AD Forest STIG.

A PKI implementation depends on the practices established by the Certificate Authority (CA) to ensure the implementation is secure. Without proper practices, the certificates issued by a CA have limited value in authentication functions. The use of multiple CAs from separate PKI implementations results in interoperability issues. If servers and clients do not have a common set of root CA certificates, they are not able to authenticate each other.If the certificates in use are issued by a CA authorized by the Components CIO, then this is a CAT II finding.

The failure to terminate inactive network connections increases the risk of a successful attack on the directory server. The longer an established session is in progress, the more time an attacker has to hijack the session, implement a means to passively intercept data, or compromise any protections on client access. For example, if an attacker gains control of a client computer, an existing (already authenticated) session with the directory server could allow access to the directory. The lack of confidentiality protection in LDAP-based sessions increases exposure to this vulnerability. System Administrator

Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\Kerberos\Parameters\ Value Name: SupportedEncryptionTypes Type: REG_DWORD The values are determined by the selection of encryption suites in the policy "Network Security: Configure encryption types allowed for Kerberos". Due to the various possible combinations, it is not possible to include all acceptable values as viewed directly in the registry. The value must be converted to binary to determine configuration of specific bits. This will determine whether this is a finding. Note the value for the registry key. For example when all suites, including the DES suites are selected, the value will be "0x7fffffff (2147483647)". Open the Windows calculator (Run/Search for "calc"). Select "View", then "Programmer". Select "Dword" and either "Hex" or "Dec". Enter the appropriate form of the value found for the registry key (e.g., Hex - enter 0x7fffffff, Dec - enter 2147483647). Select "Bin". The returned value may vary in length, up to 32 characters. If either of the 2 right most characters are "1", this is a finding.
