  # 1.1 Password Policy
  - id: 15000
    title: "Ensure 'Enforce password history' is set to '24 or more password(s)'"
    description: "This policy setting determines the number of renewed, unique passwords that have to be associated with a user account before you can reuse an old password. The value for this policy setting must be between 0 and 24 passwords. The default value for Windows Vista is 0 passwords, but the default setting in a domain is 24 passwords. To maintain the effectiveness of this policy setting, use the Minimum password age setting to prevent users from repeatedly changing their password.The recommended state for this setting is: 24 or more password(s)."
    rationale: "The longer a user uses the same password, the greater the chance that an attacker can determine the password through brute force attacks. Also, any accounts that may have been compromised will remain exploitable for as long as the password is left unchanged. If password changes are required but password reuse is not prevented, or if users continually reuse a small number of passwords, the effectiveness of a good password policy is greatly reduced.If you specify a low number for this policy setting, users will be able to use the same small number of passwords repeatedly. If you do not also configure the Minimum password age setting, users might repeatedly change their passwords until they can reuse their original password."

    title: "Ensure 'Maximum password age' is set to '365 or fewer days, but not 0'"
    description: "This policy setting defines how long a user can use their password before it expires.Values for this policy setting range from 0 to 999 days. If you set the value to 0, the password will never expire.Because attackers can crack passwords, the more frequently you change the password the less opportunity an attacker has to use a cracked password. However, the lower this value is set, the higher the potential for an increase in calls to help desk support due to users having to change their password or forgetting which password is current.The recommended state for this setting is 365 or fewer days, but not 0."
    rationale: "The longer a password exists the higher the likelihood that it will be compromised by a brute force attack, by an attacker gaining general knowledge about the user, or by the user sharing the password. Configuring the Maximum password age setting to 0 so that users are never required to change their passwords is a major security risk because that allows a compromised password to be used by the malicious user for as long as the valid user has authorized access."

    description: "This policy setting determines the number of days that you must use a password before you can change it. The range of values for this policy setting is between 1 and 999 days. (You may also set the value to 0 to allow immediate password changes.) The default value for this setting is 0 days.The recommended state for this setting is: 1 or more day(s))"
    rationale: "Users may have favorite passwords that they like to use because they are easy to remember and they believe that their password choice is secure from compromise. Unfortunately, passwords are compromised and if an attacker is targeting a specific individual's user account, with foreknowledge of data about that user, reuse of old passwords can cause a security breach. To address password reuse a combination of security settings is required. Using this policy setting with the Enforce password history setting prevents the easy reuse of old passwords. For example, if you configure the Enforce password history setting to ensure that users cannot reuse any of their last 12 passwords, they could change their password 13 times in a few minutes and reuse the password they started with, unless you also configure the Minimum password age setting to a number that is greater than 0. You must configure this policy setting to a number that is greater than 0 for the Enforce password history setting to be effective."

    title: "Ensure 'Minimum password length' is set to '14 or more character(s)'"
    description: "This policy setting determines the least number of characters that make up a password for a user account. There are many different theories about how to determine the best password length for an organization, but perhaps 'passphrase' is a better term than 'password.' In Microsoft Windows 2000 and newer, passphrases can be quite long and can include spaces. Therefore, a phrase such as 'I want to drink a $5 milkshake' is a valid passphrase; it is a considerably stronger password than an 8 or 10 character string of random numbers and letters, and yet is easier to remember. Users must be educated about the proper selection and maintenance of passwords, especially with regard to password length. In enterprise environments, the ideal value for the Minimum password length setting is 14 characters, however you should adjust this value to meet your organization's business requirements.The recommended state for this setting is: 14 or more character(s)."
    rationale: "Types of password attacks include dictionary attacks (which attempt to use common words 'and phrases) and brute force attacks (which try every possible combination of characters). 'Also, attackers sometimes try to obtain the account database so they can use tools to 'discover the accounts and passwords"

    description: "This policy setting determines the length of time that must pass before a locked account is unlocked and a user can try to log on again. The setting does this by specifying the number of minutes a locked out account will remain unavailable. If the value for this policy setting is configured to 0, locked out accounts will remain locked out until an administrator manually unlocks them."
    rationale: "A denial of service (DoS) condition can be created if an attacker abuses the Account lockout threshold and repeatedly attempts to log on with a specific account. Once you configure theAccount lockout threshold setting, the account will be locked out after the specified number of failed attempts. If you configure the Account lockout duration setting to 0, then the account will remain locked out until an administrator unlocks it manually."

    description: "This policy setting determines the number of failed logon attempts before the account is locked. Setting this policy to 0 does not conform to the benchmark as doing so disables the account lockout threshold"
    rationale: "Setting an account lockout threshold reduces the likelihood that an online password brute force attack will be successful. Setting the account lockout threshold too low introduces risk of increased accidental lockouts and/or a malicious actor intentionally locking out accounts."

    description: "This policy setting determines the length of time before the Account lockout threshold resets to zero. The default value for this policy setting is Not Defined. If the Account lockout threshold is defined, this reset time must be less than or equal to the value for the Account lockout duration setting."
    rationale: "Users can accidentally lock themselves out of their accounts if they mistype their password multiple times. To reduce the chance of such accidental lockouts, the Reset account lockout counter after setting determines the number of minutes that must elapse before the counter that tracks failed logon attempts and triggers lockouts is reset to 0."

    description: "This policy setting enables or disables the Administrator account during normal operation. When a computer is booted into safe mode, the Administrator account is always enabled, regardless of how this setting is configured. Note that this setting will have no impact when applied to the Domain Controllers organizational unit via group policy because Domain Controllers have no local account database. It can be configured at the domain level via group policy, similar to account lockout and password policy settings."
    rationale: "In some organizations, it can be a daunting management challenge to maintain a regular schedule for periodic password changes for local accounts. Therefore, you may want to disable the built-in Administrator account instead of relying on regular password changes to protect it from attack. Another reason to disable this built-in account is that it cannot be locked out no matter how many failed logons it accrues, which makes it a prime target for brute force attacks that attempt to guess passwords. Also, this account has a well-known security identifier (SID) and there are third-party tools that allow authentication by using the SID rather than the account name. This capability means that even if you rename the Administrator account, an attacker could launch a brute force attack by using the SID to log on."

    description: "This policy setting prevents users from adding new Microsoft accounts on this computer. The recommended state for this setting is: Users can't add or log on with Microsoft accounts."
    rationale: "Organizations that want to effectively implement identity management policies and maintain firm control of what accounts are used to log onto their computers will probably want to block Microsoft accounts. Organizations may also need to block Microsoft accounts in order to meet the requirements of compliance standards that apply to their information systems."

    title: "Ensure 'Accounts: Guest account status' is set to 'Disabled'"
    description: "This policy setting determines whether the Guest account is enabled or disabled. The Guest account allows unauthenticated network users to gain access to the system."
    rationale: "The default Guest account allows unauthenticated network users to log on as Guest with no password. These unauthorized users could access any resources that are accessible to the Guest account over the network. This capability means that any network shares with permissions that allow access to the Guest account, the Guests group, or the Everyone group will be accessible over the network, which could lead to the exposure or corruption of data."

    description: "This policy setting determines whether local accounts that are not password protected can be used to log on from locations other than the physical computer console. If you enable this policy setting, local accounts that have blank passwords will not be able to log on to the network from remote client computers. Such accounts will only be able to log on at the keyboard of the computer. The recommended state for this setting is: Enabled."
    rationale: "Blank passwords are a serious threat to computer security and should be forbidden through both organizational policy and suitable technical measures. In fact, the default settings for Active Directory domains require complex passwords of at least seven characters. However, if users with the ability to create new accounts bypass your domainbased password policies, they could create accounts with blank passwords. For example, a user could build a stand-alone computer, create one or more accounts with blank passwords, and then join the computer to the domain. The local accounts with blank passwords would still function. Anyone who knows the name of one of these unprotected accounts could then use it to log on."

    description: "This policy setting allows administrators to enable the more precise auditing capabilities present in Windows Vista. The Audit Policy settings available in Windows Server 2003 Active Directory do not yet contain settings for managing the new auditing subcategories. To properly apply the auditing policies prescribed in this baseline, the Audit: Force audit policy subcategory settings (Windows Vista or later) to override audit policy category settings setting needs to be configured to Enabled. The recommended state for this setting is: Enabled. *Important*: Be very cautious about audit settings that can generate a large volume of traffic. For example, if you enable either success or failure auditing for all of the Privilege Use subcategories, the high volume of audit events generated can make it difficult to find other types of entries in the Security log. Such a configuration could also have a significant impact on system performance."
    rationale: "Prior to the introduction of auditing subcategories in Windows Vista, it was difficult to track events at a per-system or per-user level. The larger event categories created too many events and the key information that needed to be audited was difficult to find."

    rationale: "It may be appropriate in some organizations to allow users to install printer drivers on their own workstations. However, you should allow only Administrators, not users, to do so on servers, because printer driver installation on a server may unintentionally cause the computer to become less stable. A malicious user could install inappropriate printer drivers in a deliberate attempt to damage the computer, or a user might accidentally install malicious software that masquerades as a printer driver.

    rationale: "When connecting to computers running versions of Windows earlier than Windows Vista or Windows Server 2008 (non-R2), services running as Local System and using SPNEGO (Negotiate) that revert to NTLM use the computer identity. In Windows 7, if you are connecting to a computer running Windows Server 2008 or Windows Vista, then a system service uses either the computer identity or a NULL session. When connecting with a NULL session, a system-generated session key is created, which provides no protection but allows applications to sign and encrypt data without errors. When connecting with the computer identity, both signing and encryption is supported in order to provide data protection."

    description: "This setting determines if online identities are able to authenticate to this computer. The Public Key Cryptography Based User-to-User (PKU2U) protocol introduced in Windows 7 and Windows Server 2008 R2 is implemented as a security support provider (SSP). The SSP enables peer-to-peer authentication, particularly through the Windows 7 media and file sharing feature called Homegroup, which permits sharing between computers that are not members of a domain. With PKU2U, a new extension was introduced to the Negotiate authentication package, Spnego.dll. In previous versions of Windows, Negotiate decided whether to use Kerberos or NTLM for authentication. The extension SSP for Negotiate, Negoexts.dll, which is treated as an authentication protocol by Windows, supports Microsoft SSPs including PKU2U. When computers are configured to accept authentication requests by using online IDs, Negoexts.dll calls the PKU2U SSP on the computer that is used to log on. The PKU2U SSP obtains a local certificate and exchanges the policy between the peer computers. When validated on the peer computer, the certificate within the metadata is sent to the logon peer for validation and associates the user's certificate to a security token and the logon process completes. The recommended state for this setting is: Disabled."

  - id: 15060
    title: "Ensure 'Network security: LAN Manager authentication level' is set to 'Send NTLMv2 response only. Refuse LM & NTLM'"
    description: "LAN Manager (LM) was a family of early Microsoft client/server software (predating Windows NT) that allowed users to link personal computers together on a single network. LM network capabilities included transparent file and print sharing, user security features, and network administration tools. In Active Directory domains, the Kerberos protocol is the default authentication protocol. However, if the Kerberos protocol is not negotiated for some reason, Active Directory will use LM, NTLM, or NTLMv2. LAN Manager authentication includes the LM, NTLM, and NTLM version 2 (NTLMv2) variants, and is the protocol that is used to authenticate all Windows clients when they perform the following operations: -Join a domain -Authenticate between Active Directory forests -Authenticate to down-level domains -Authenticate to computers that do not run Windows 2000, Windows Server 2003, or Windows XP -Authenticate to computers that are not in the domain. The Network security: LAN Manager authentication level setting determines which challenge/response authentication protocol is used for network logons. This choice affects the level of authentication protocol used by clients, the level of session security negotiated, and the level of authentication accepted by servers. The recommended state for this setting is: Send NTLMv2 response only. Refuse LM & NTLM."
    rationale: "Windows 2000 and Windows XP clients were configured by default to send LM and NTLM authentication responses (Windows 95-based and Windows 98-based clients only send LM). The default settings in OSes predating Windows Vista / Windows Server 2008 (non- R2) allowed all clients to authenticate with servers and use their resources. However, this meant that LM responses - the weakest form of authentication response - were sent over the network, and it was potentially possible for attackers to sniff that traffic to more easily reproduce the user's password. The Windows 95, Windows 98, and Windows NT operating systems cannot use the Kerberos version 5 protocol for authentication. For this reason, in a Windows Server 2003 domain, these computers authenticate by default with both the LM and NTLM protocols for network authentication. You can enforce a more secure authentication protocol for Windows 95, Windows 98, and Windows NT by using NTLMv2. For the logon process, NTLMv2 uses a secure channel to protect the authentication process. Even if you use NTLMv2 for older clients and servers, Windows-based clients and servers that are members of the domain will use the Kerberos authentication protocol to authenticate with Windows Server 2003 or newer Domain Controllers. For these reasons, it is strongly preferred to restrict the use of LM & NTLM (non-v2) as much as possible."
    remediation: "To establish the recommended configuration via GP, set the following UI path to: Send NTLMv2 response only. Refuse LM & NTLM: Computer Configuration\\Policies\\Windows Settings\\Security Settings\\Local Policies\\Security Options\\Network security: LAN Manager authentication level."

    rationale: "One of the risks that the User Account Control feature introduced with Windows Vista is trying to mitigate is that of malicious software running under elevated credentials without the user or administrator being aware of its activity. An attack vector for these programs was to discover the password of the account named 'Administrator' because that user account was created for all installations of Windows. To address this risk, in Windows Vista and newer, the built-in Administrator account is now disabled by default. In a default installation of a new computer, accounts with administrative control over the computer are initially set up in one of two ways: - If the computer is not joined to a domain, the first user account you create has the equivalent permissions as a local administrator. - If the computer is joined to a domain, no local administrator accounts are created. The Enterprise or Domain Administrator must log on to the computer and create one if a local administrator account is warranted. Once Windows is installed, the built-in Administrator account may be manually enabled, but we strongly recommend that this account remain disabled."

Events for this subcategory include: - 4960: IPsec dropped an inbound packet that failed an integrity check. If this  problem persists, it could indicate a network issue or that packets are being  modified in transit to this computer. Verify that the packets sent from the remote  computer are the same as those received by this computer. This error might also  indicate interoperability problems with other IPsec implementations. - 4961: IPsec dropped an inbound packet that failed a replay check. If this problem  persists, it could indicate a replay attack against this computer. - 4962: IPsec dropped an inbound packet that failed a replay check. The inbound  packet had too low a sequence number to ensure it was not a replay. - 4963: IPsec dropped an inbound clear text packet that should have been secured.  This is usually due to the remote computer changing its IPsec policy without  informing this computer. This could also be a spoofing attack attempt. - 4965: IPsec received a packet from a remote computer with an incorrect Security  Parameter Index (SPI). This is usually caused by malfunctioning hardware that is  corrupting packets. If these errors persist, verify that the packets sent from the  remote computer are the same as those received by this computer. This error may  also indicate interoperability problems with other IPsec implementations. In that  case, if connectivity is not impeded, then these events can be ignored. - 5478: IPsec Services has started successfully. - 5479: IPsec Services has been shut down successfully. The shutdown of IPsec  Services can put the computer at greater risk of network attack or expose the  computer to potential security risks. - 5480: IPsec Services failed to get the complete list of network interfaces on the  computer. This poses a potential security risk because some of the network interfaces may not get the protection provided by the applied IPsec filters. Use the  IP Security Monitor snap-in to diagnose the problem. - 5483: IPsec Services failed to initialize RPC server. IPsec Services could not be  started.- 5484: IPsec Services has experienced a critical failure and has been shut down. The  shutdown of IPsec Services can put the computer at greater risk of network attack  or expose the computer to potential security risks. - 5485: IPsec Services failed to process some IPsec filters on a plug-and-play event for  network interfaces.

    description: "In May 2015, Microsoft released the Local Administrator Password Solution (LAPS) tool, which is free and supported software that allows an organization to automatically set randomized and unique local Administrator account passwords on domain-attached workstations and Member Servers. The passwords are stored in a confidential attribute of the domain computer account and can be retrieved from Active Directory by approved Sysadmins when needed. The LAPS tool requires a small Active Directory Schema update in order to implement, as well as installation of a Group Policy Client Side Extension (CSE) on targeted computers. Please see the LAPS documentation for details. LAPS supports Windows Vista or newer workstation OSes, and Server 2003 or newer server OSes. LAPS does not support standalone computers - they must be joined to a domain. Note: Organizations that utilize 3rd-party commercial software to manage unique & complex local Administrator passwords on domain members may opt to disregard these LAPS recommendations. Note #2: LAPS is only designed to manage local Administrator passwords, and is therefore not recommended (or supported) for use directly on Domain Controllers, which do not have a traditional local Administrator account. We strongly encourage you to only deploy the LAPS CSE and LAPS GPO settings to member servers and workstations."
    rationale: "Due to the difficulty in managing local Administrator passwords, many organizations choose to use the same password on all workstations and/or Member Servers when deploying them. This creates a serious attack surface security risk because if an attacker manages to compromise one system and learn the password to its local Administrator account, then they can leverage that account to instantly gain access to all other computers that also use that password for their local Administrator account."

IPv6 allows for many more IP addresses to be assigned than IPv4 did. Older networking, hosts and operating systems may not support IPv6 natively. The recommended state for this setting is: DisabledComponents - 0xff (255)"
    rationale: "Since the vast majority of private enterprise managed networks have no need to utilize IPv6 (because they have access to private IPv4 addressing), disabling IPv6 components reduces a possible attack surface that is also harder to monitor the traffic on. As a result, we recommend configuring IPv6 to a Disabled state when it is not needed."

Select Fast to participate in identifying and reporting issues to Microsoft, and provide suggestions on new functionality. - Preview Build - Slow: Devices set to this level receive new builds of Windows before they are available to the general public, but at a slower cadence than those set to Fast, and with changes and fixes identified in earlier builds. - Release Preview: Receive builds of Windows just before Microsoft releases them to the general public. - Semi-Annual Channel (Targeted): Receive feature updates when they are released to the general public. - Semi-Annual Channel: Feature updates will arrive when they are declared SemiAnnual Channel. This usually occurs about 4 months after Semi-Annual Channel (Targeted), indicating that Microsoft, Independent Software Vendors (ISVs), partners and customer believe that the release is ready for broad deployment."
