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.

The FTP (File Transfer Protocol) service allows remote users to access shared files and directories. Allowing anonymous FTP connections makes user auditing difficult. Using accounts that have administrator privileges to log on to FTP risks that the userid and password will be captured on the network and give administrator access to an unauthorized user.If accounts with administrator privileges are used to access FTP, this becomes a CAT I finding.

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 member servers, the Domain Admins group must be replaced by a domain member server administrator group (see V-36433 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.

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, and anything the second user does with that process will be performed with the privileges of the first user.HKECSC-1

Checks: C-61749r2_chk

Verify whether the registry key below exists. If it does not exist or the value is "0", this is not a finding. If the registry key exists and contains a value other than "0", continue below. The values are determined by the selection of encryption suites in the policy Computer Configuration &gt;&gt; Windows Settings &gt;&gt; Security Settings &gt;&gt; Local Policies &gt;&gt; Security Options &gt;&gt; "Network Security: Configure encryption types allowed for Kerberos". Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\Kerberos\Parameters\ Value Name: SupportedEncryptionTypes Type: REG_DWORD Due to the number of possible combinations that may include the DES encryption types, it is not possible to include all acceptable values as viewed directly in the registry. If the registry key does exist, 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 the either of 2 right most characters are "1", this is a finding. If the both of 2 right most characters are "0", this is not a finding.

Web browsers and email are common attack vectors for introducing malicious code and must not be run with an administrative account. Since administrative accounts may generally change or work around technical restrictions for running a web browser or other applications, it is essential that policy requires administrative accounts to not access the Internet or use applications, such as email.

Information can be either unintentionally or maliciously disclosed or modified during preparation for transmission, for example, during aggregation, at protocol transformation points, and during packing/unpacking. These unauthorized disclosures or modifications compromise the confidentiality or integrity of the information. Ensuring the confidentiality of transmitted information requires the operating system to take measures in preparing information for transmission. This can be accomplished via access control and encryption. Use of this requirement will be limited to situations where the data owner has a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process. When transmitting data, operating systems need to support transmission protection mechanisms such as TLS, encrypted VPNs, or IPSEC.

If temporary user accounts remain active when no longer needed or for an excessive period, these accounts may be used to gain unauthorized access. To mitigate this risk, automated termination of all temporary accounts must be set upon account creation. Temporary accounts are established as part of normal account activation procedures when there is a need for short-term accounts without the demand for immediacy in account activation. If temporary accounts are used, the operating system must be configured to automatically terminate these types of accounts after a DoD-defined time period of 72 hours. To address access requirements, many operating systems may be integrated with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements.

Emergency administrator accounts are privileged accounts which are established in response to crisis situations where the need for rapid account activation is required. Therefore, emergency account activation may bypass normal account authorization processes. If these accounts are automatically disabled, system maintenance during emergencies may not be possible, thus adversely affecting system availability. Emergency administrator accounts are different from infrequently used accounts (i.e., local logon accounts used by system administrators when network or normal logon/access is not available). Infrequently used accounts also remain available and are not subject to automatic termination dates. However, an emergency administrator account is normally a different account which is created for use by vendors or system maintainers. To address access requirements, many operating systems can be integrated with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements.
