Tanzu Application Service (TAS for VMs) satisfies all of the implied technical control requirements. The organization’s procedural controls will be inherited by the TAS for VMs deployment. TAS for VMs may be configured to protect audit data using TLS as it is transfered from the TAS for VMs environment to the enterprise log management system. TAS for VMs provides native controls for limiting access to application logs while these logs are present within the TAS for VMs environment, via Cloud Controller logical access controls including RBAC roles, and the appropriate use of Orgs and Spaces by the deployer.
Deployers that require immutability of the Linux OS audit log rules must create a BOSH Add-on release.
The default configuration of the stemcell does not mark the Linux audit rules file as immutable because this would block the deployer from appending additional audit rules when deploying, for example, a site-specific security agent.
Once audit log data has been transferred to the enterprise log management system, the protection of archived audit log information from unauthorized access, modification, and deletion is the responsibility of the deployer.
The information system protects audit information and audit tools from unauthorized access, modification, and deletion.
Audit information includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit information system activity. This control focuses on technical protection of audit information. Physical protection of audit information is addressed by media protection controls and physical and environmental protection controls.
