Compliance
The following 27 compliance controls are associated with this Policy definition 'Audit Linux machines that allow remote connections from accounts without passwords' (ea53dbee-c6c9-4f0e-9f9e-de0039b78023)
Limit information system access to authorized users, processes acting on behalf of authorized users, and devices (including other information systems).
Shared
Microsoft and the customer share responsibilities for implementing this requirement.
Access control policies (e.g., identity- or role-based policies, control matrices, and cryptography) control access between active entities or subjects (i.e., users or processes acting on behalf of users) and passive entities or objects (e.g., devices, files, records, and domains) in systems. Access enforcement mechanisms can be employed at the application and service level to provide increased information security. Other systems include systems internal and external to the organization. This requirement focuses on account management for systems and applications. The definition of and enforcement of access authorizations, other than those determined by account type (e.g., privileged verses non-privileged) are addressed in requirement AC.1.002.
Limit information system access to the types of transactions and functions that authorized users are permitted to execute.

Organizations may choose to define access privileges or other attributes by account, by type of account, or a combination of both. System account types include individual, shared, group, system, anonymous, guest, emergency, developer, manufacturer, vendor, and temporary. Other attributes required for authorizing access include restrictions on time-of-day, day-of-week, and point-oforigin. In defining other account attributes, organizations consider system-related requirements (e.g., system upgrades scheduled maintenance,) and mission or business requirements, (e.g., time zone differences, customer requirements, remote access to support travel requirements).

Remote access is access to organizational systems by users (or processes acting on behalf of users) communicating through external networks (e.g., the Internet). Remote access methods include dial-up, broadband, and wireless. Organizations often employ encrypted virtual private networks (VPNs) to enhance confidentiality over remote connections. The use of encrypted VPNs does not make the access non-remote; however, the use of VPNs, when adequately provisioned with appropriate control (e.g., employing encryption techniques for confidentiality protection), may provide sufficient assurance to the organization that it can effectively treat such connections as internal networks. VPNs with encrypted tunnels can affect the capability to adequately monitor network communications traffic for malicious code.
Automated monitoring and control of remote access sessions allows organizations to detect cyberattacks and help to ensure ongoing compliance with remote access policies by auditing connection activities of remote users on a variety of system components (e.g., servers, workstations, notebook computers, smart phones, and tablets).
The organization:
a. Establishes and documents usage restrictions, configuration/connection requirements, and implementation guidance for each type of remote access allowed; and
b. Authorizes remote access to the information system prior to allowing such connections.
Supplemental Guidance: Remote access is access to organizational information systems by users (or processes acting on behalf of users) communicating through external networks (e.g., the Internet). Remote access methods include, for example, dial-up, broadband, and wireless. Organizations often employ encrypted virtual private networks (VPNs) to enhance confidentiality and integrity over remote connections. The use of encrypted VPNs does not make the access non-remote; however, the use of VPNs, when adequately provisioned with appropriate security controls (e.g., employing appropriate encryption techniques for confidentiality and integrity protection) may provide sufficient assurance to the organization that it can effectively treat such connections as internal networks. Still, VPN connections traverse external networks, and the encrypted VPN does not enhance the availability of remote connections. Also, VPNs with encrypted tunnels can affect the organizational capability to adequately monitor network communications traffic for malicious code. Remote access controls apply to information systems other than public web servers or systems designed for public access. This control addresses authorization prior to allowing remote access without specifying the formats for such authorization. While organizations may use interconnection security agreements to authorize remote access connections, such agreements are not required by this control. Enforcing access restrictions for remote connections is addressed in AC-3. Related controls: AC-2, AC-3, AC-18, AC-19, AC-20, CA-3, CA-7, CM-8, IA-2, IA-3, IA-8, MA-4, PE-17, PL-4, SC-10, SI-4.

The agency must:
a. Establish and document usage restrictions, configuration/connection requirements, and implementation guidance for each type of remote access allowed
b. Authorize remote access to the information system prior to allowing such connections
c. Authorize and document the execution of privileged commands and access to security-relevant information via remote access for compelling operational needs only (CE4)
The information system must:
a. Monitor and control remote access methods (CE1)
b. Implement cryptographic mechanisms to protect the confidentiality and integrity of remote access sessions where FTI is transmitted over the remote connection and (CE2)
c. Route all remote accesses through a limited number of managed network access control points (CE3)
Remote access is defined as any access to an agency information system by a user communicating through an external network, for example, the Internet.
Any remote access where FTI is accessed over the remote connection must be performed using multi-factor authentication.
FTI cannot be accessed remotely by agency employees, agents, representatives, or contractors located offshore--outside of the United States territories, embassies, or military installations. Further, FTI may not be received, processed, stored, transmitted, or disposed of by IT systems located offshore.
Limit system access to authorized users, processes acting on behalf of authorized users, and devices (including other systems).

All application and operating system accounts enforce passwords with appropriate parameters such as length, complexity, validity, and the number of failed login attempts. Similarly, personal tokens and mobile devices enforce passwords or a Personal Identification Number (PIN) with appropriate parameters.
