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

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.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

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

Verify that the site is applying all security-related patches released by Microsoft. Determine the local site method for doing this (e.g., connection to a WSUS server, local procedure, etc.). 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.

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

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.

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

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

Application/service account passwords must be at least 15 characters and follow complexity requirements for all passwords.System AdministratorInformation Assurance Officer
Checks: C-79569r2_chk

Determine if manually managed application/service accounts exist. If none exist, this is NA. Verify the organization has a policy to ensure passwords for manually managed application/service accounts are at least 15 characters in length. It must also require the passwords be changed at least annually or when an administrator with knowledge of the password leaves the organization. If such a policy does not exist or has not been implemented, this is a finding. Identify manually managed application/service accounts. Open a "Command Prompt" with elevated privileges (run as administrator). Enter 'Net User [application account name] | Find /i "Password Last Set"', where [application account name] is the name of the manually managed application/service account. If the "Password Last Set" date is more than one year old, this is a finding. Domain Controllers: The following may also be used on domain controllers: Enter “Dsquery user -limit 0 -o rdn -stalepwd 365”. This will return a list of User Accounts with passwords older the one year. If any application account is returned as having a password older than one year, this is a finding.

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. Premise firewall or host restrictions prevent access to ports 389, 636, 3268, and 3269 from client hosts not explicitly identified by domain (.mil) or IP address.System Administrator
Checks: C-46916r1_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. Confirmation of anonymous access will be displayed at the end: res = ldap_simple_bind_s Authenticated as: 'NT AUTHORITY\ANONYMOUS LOGON'

Fix: F-45045r1_fix

Implement network protections to reduce the risk of anonymous access. Network hardware ports at the site are subject to 802.1x authentication or MAC address restrictions.

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. Premise firewall or host restrictions prevent access to ports 389, 636, 3268, and 3269 from client hosts not explicitly identified by domain (.mil) or IP address.System Administrator
Checks: C-46918r1_chk

Verify anonymous access is not allowed to the AD domain naming context. 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. 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-45048r1_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. System Administrator

Verify the source of the domain controller's server certificate. Run "mmc". Select "Add/Remove Snap-in" from the File menu. Select "Certificates" in the left pane and click the "Add &gt;" button. Select "Computer Account", click "Next". Select the appropriate option for "Select the computer you want this snap-in to manage.", click "Finish". Click "OK". Select and expand the Certificates (Local Computer) entry in the left pane. Select and expand the Personal entry in the left pane. Select the Certificates entry in the left pane. In the right pane, examine the Issued By field for the certificate to determine the issuing CA. If the Issued By field of the PKI certificate being used by the domain controller does not indicate the issuing Certificate Authority (CA) is part of the DoD PKI or an approved ECA, this is a finding. There are multiple sources from which lists of valid DoD CAs and approved ECAs can be obtained: The Global Directory Service (GDS) website provides an online source. The address for this site is https://crl.gds.disa.mil. DoD Public Key Enablement (PKE) Engineering Support maintains the InstallRoot utility to manage DoD supported root certificates on Windows computers which includes a list of authorized CAs. The utility package can be downloaded from the PKI and PKE Tools page on IASE. http://iase.disa.mil/pki-pke/function_pages/tools.html

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

When directory service database objects do not have appropriate access control permissions, it may be possible for malicious users to create, read, update, or delete the objects and degrade or destroy the integrity of the data. When the directory service is used for identification, authentication, or authorization functions, a compromise of the database objects could lead to a compromise of all systems relying on the directory service. For Active Directory (AD), the Group Policy objects require special attention. In a distributed administration model (i.e., help desk), Group Policy objects are more likely to have access permissions changed from the secure defaults. If inappropriate access permissions are defined for Group Policy Objects, this could allow an intruder to change the security policy applied to all domain client computers (workstations and servers).System Administrator
Checks: C-51587r2_chk

Verify the permissions on Group Policy objects. Open "Group Policy Management". (Available from various menus or run "gpmc.msc".) Navigate to "Group Policy Objects" in the domain being reviewed (Forest &gt; Domains &gt; Domain). For each Group Policy object: Select the Group Policy object item in the left pane. Select the Delegation tab in the right pane. Select the Advanced button. If any standard user accounts or groups have greater than Allow permissions of Read and Apply group policy, this is a finding. Other access permissions that allow the objects to be updated are considered findings unless specifically documented by the IAO. The default permissions noted below meet this requirement. The permissions shown are at the summary level. More detailed permissions can be viewed by selecting the next Advanced button, selecting the desired Permission entry, and the Edit button. Authenticated Users - Read, Apply group policy, Special permissions The Special permissions for Authenticated Users are for Read type Properties. If detailed permissions include any Create, Delete, Modify, or Write Permissions or Properties, this is a finding. The Special permissions for the following default groups are not the focus of this requirement and may include a wide range of permissions and properties. CREATOR OWNER - Special permissions SYSTEM - Read, Write, Create all child objects, Delete all child objects, Special permissions Domain Admins - Read, Write, Create all child objects, Delete all child objects, Special permissions Enterprise Admins - Read, Write, Create all child objects, Delete all child objects, Special permissions ENTERPRISE DOMAIN CONTROLLERS - Read, Special permissions The Domain Admins and Enterprise Admins will not have the "Delete all child objects" permission on the two default group policy objects: Default Domain Policy and Default Domain Controllers Policy. They will have this permission on created group policy objects. The Anonymous Logon, Guests, or any group that contains those groups (in which users are not uniquely identified and authenticated) must not have any access permissions unless the group and justification is explicitly documented with the IAO.

Using applications that access the internet or have potential internet sources using administrative privileges exposes a system to compromise. 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. Technical means such as application whitelisting can be used to enforce the policy to ensure compliance.
Checks: C-74317r2_chk

Determine whether administrative accounts are prevented from using applications that access the Internet, such as web browsers, or with potential Internet sources, such as email, except as necessary for local service administration. The organization must have a policy that prohibits administrative accounts from using applications that access the Internet, such as web browsers, or with potential Internet sources, such as email, except as necessary for local service administration. 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. Technical measures such as the removal of applications or application whitelisting must be used where feasible to prevent the use of applications that access the Internet. If accounts with administrative privileges are not prevented from using applications that access the Internet or with potential Internet sources, this is a finding.

When inappropriate audit settings are configured for directory service database objects, it may be possible for a user or process to update the data without generating any tracking data. The impact of missing audit data is related to the type of object. A failure to capture audit data for objects used by identification, authentication, or authorization functions could degrade or eliminate the ability to track changes to access policy for systems or data. For Active Directory (AD), there are a number of critical object types in the domain naming context of the AD database for which auditing is essential. This includes Group Policy objects. Because changes to these objects can significantly impact access controls or the availability of systems, the absence of auditing data makes it impossible to identify the source of changes that impact the confidentiality, integrity, and availability of data and systems throughout an AD domain. The lack of proper auditing can result in insufficient forensic evidence needed to investigate an incident and prosecute the intruder.

When Active Directory (AD) objects do not have appropriate access control permissions, it may be possible for malicious users to create, read, update, or delete the objects and degrade or destroy the integrity of the data. When the directory service is used for identification, authentication, or authorization functions, a compromise of the database objects could lead to a compromise of all systems that rely on the directory service. AD Organizational Unit (OU) objects require special attention. In a distributed administration model (i.e., help desk), OU objects are more likely to have access permissions changed from the secure defaults. Inappropriate access permissions defined for OU objects could allow an intruder or unauthorized personnel to add or delete accounts in the OU. This could result in unauthorized access to data or a Denial of Service to authorized users.If any OU with improper permissions includes identification or authentication data (e.g., accounts, passwords, or password hash data) used by systems to determine access control, the severity is Category I (e.g., OUs that include user accounts, including service/application accounts). If the OU with improper permissions does not include identification and authentication data used by systems to determine access control, the severity is Category II (e.g., Workstation, Printer OUs).
Checks: C-49414r3_chk

Verify the permissions on domain defined OUs. Open "Active Directory Users and Computers". (Available from various menus or run "dsa.msc".) Select Advanced Features in the View menu if not previously selected. For each OU that is defined (folder in folder icon), excluding the Domain Controllers OU: Right click the OU and select Properties. Select the Security tab. If the permissions on the OU are not at least as restrictive as those below, this is a finding. The permissions shown are at the summary level. More detailed permissions can be viewed by selecting the Advanced button, selecting the desired Permission entry and the Edit button.

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.
Checks: C-75607r2_chk

Review the effective User Rights setting in Local Group Policy Editor. Run "gpedit.msc". Navigate to Local Computer Policy &gt;&gt; Computer Configuration &gt;&gt; Windows Settings &gt;&gt; Security Settings &gt;&gt; Local Policies &gt;&gt; User Rights Assignment. Review each User Right listed for any unresolved SIDs to determine whether they are valid, such as due to being temporarily disconnected from the domain. (Unresolved SIDs have the format of "*S-1-…".) If any unresolved SIDs exist and are not for currently valid accounts or groups, this is a finding.

Fix: F-82549r1_fix

Remove any unresolved SIDs found in User Rights assignments and determined to not be for currently valid accounts or groups by removing the accounts or groups from the appropriate group policy.

The krbtgt account acts as a service account for the Kerberos Key Distribution Center (KDC) service. The account and password are created when a domain is created and the password is typically not changed. If the krbtgt account is compromised, attackers can create valid Kerberos Ticket Granting Tickets (TGT). The password must be changed twice to effectively remove the password history. Changing once, waiting for replication to complete and changing again reduces the risk of issues. Changing twice in rapid succession forces clients to re-authenticate (including application services) but is desired if a compromise is suspected.
Checks: C-90931r1_chk

This requirement is applicable to domain controllers; it is NA for other systems. Open "Windows PowerShell". Enter "Get-ADUser krbtgt -Property PasswordLastSet". If the "PasswordLastSet" date is more than 180 days old, this is a finding.

Fix: F-97975r1_fix

Reset the password for the krbtgt account a least every 180 days. The password must be changed twice to effectively remove the password history. Changing once, waiting for replication to complete and changing again reduces the risk of issues. Changing twice in rapid succession forces clients to re-authenticate (including application services) but is desired if a compromise is suspected. PowerShell scripts are available to accomplish this such as at the following link: https://gallery.technet.microsoft.com/Reset-the-krbtgt-account-581a9e51 Open "Active Directory Users and Computers" (available from various menus or run "dsa.msc"). Select "Advanced Features" in the "View" menu if not previously selected. Select the "Users" node. Right click on the krbtgt account and select "Reset password". Enter a password that meets password complexity requirements. Clear the "User must change password at next logon" check box. The system will automatically change this to a system generated complex password.
