Pivotal Web Services is a cloud based application hosting platform, managed and operated by Pivotal Software, Inc. (“Pivotal”) and hosted on Amazon Web Services (“AWS”) in the United States (“PWS”). PWS is a hosted version of the open source Cloud Foundry platform-as-a-service software. Pivotal leverages a combination of internal and operational controls, along with controls provided by AWS to protect the security of the platform.
As infrastructure-as-a-service (“IaaS”) providers invested in the security of their environments, AWS makes use of a wide range of industry certifications and independent third-party attestations. Detailed IaaS-specific security information can be obtained from AWS Cloud Compliance. The following are some examples of security certifications held by AWS:
PWS stores the following customer application data and account information:
Cloud Foundry provides isolation through its governance framework features, which defines groupings of apps and services into entities known as Organizations and Spaces. PWS users are assigned to organizations and spaces by the Organization Manager role designated at account creation and through system user interfaces. Access scope is governed by the roles users possess in those entities. It is through these roles and scopes that multi-tenancy is achieved. Users’ administrative access is limited to their assigned organizations and spaces. An application’s access is governed by the application access rules defined within the application. Apps are internet routable entities, which are generally accessible from the public internet.
Applications on PWS are deployed into “containers” and isolated from other applications. Because applications are deployed onto shared infrastructure, these containers may be co-resident with other containers on AWS EC2 Instances provisioned by PWS. These AWS EC2 instances may be co-resident with other AWS EC2 instances on shared physical machines.
Cloud Foundry and AWS provide isolation that enhances security and relative performance separation. The container runtime is designed to ensure that adjacent containers are unable to access data or connectivity between containers unless explicitly permitted by defined policies.
Administrative access to the PWS environment, including customer applications, is only provided to Pivotal employees located in the United States, Canada, the United Kingdom, and Ireland with a business need (e.g., in order to maintain the PWS environment), and is removed when access is no longer required.
PWS relies on the availability model of the underlying AWS infrastructure and supports multiple AWS availability zones (AZs) within the AWS US-East Region (Virginia). PWS can distribute instances of an application across the AWS AZs to ensure availability of applications in the event of an AWS data center failure. This availability requires that multiple instances of applications be deployed. Failure of the US East AWS region may impact availability of hosted applications.
For purposes of data locality, operational data that is at rest resides solely in the environment where applications are deployed. For PWS, application and operation data resides in AWS in the United States. Customers are responsible for monitoring the availability and performance of their applications.
Pivotal periodically uses third-party security firms to perform security assessments of the PWS environments. These assessments are performed at a minimum of once a year. Any resulting findings are prioritized and addressed according to Pivotal policies and industry best practices. Although specific results from these assessments cannot be provided to customers, upon request Pivotal may share information with customers about the methodology and scope of its security assessments.
Customers may test their own applications hosted on PWS with prior written approval from Pivotal, but due to the multi-tenant nature of the environment, customer security assessments of PWS itself are not permitted.
If you have any questions about the PWS security program, or would like to obtain approval for testing your own applications hosted on PWS, contact us at firstname.lastname@example.org.
