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

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.

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'

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
Checks: C-48704r1_chk

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
