VMware Tanzu Application Service Compliance
Tanzu Application Service (TAS for VMs) complies with this requirement by providing TLS 1.2 support for all user network connections. However, TAS for VMs does not provide any native support for “remote” access, and inherits controls from the supporting infrastructure.
Control Description
The organization:
- Establishes and documents usage restrictions, configuration/connection requirements, and implementation guidance for each type of remote access allowed; and
- 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.
