DoD STIGs – V-32458

Overview:

Title: Web services applications establishing identities at run-time for previously unknown entities must dynamically manage identifiers, attributes, and associated access authorizations.

Vulnerability ID: V-32458

STIG ID:

IA Controls: None

Severity: medium

Description: Web services are web applications providing a method of communication between two or more different electronic devices. They are normally used by applications to provide each other with data.

The W3C defines a web service as:
“a software system designed to support interoperable machine to machine interaction over a network. It has an interface described in a machine processable format (specifically Web Services Description Language or WSDL). Other systems interact with the web service in a manner prescribed by its description using SOAP messages typically conveyed using HTTP with an XML serialization in conjunction with other web-related standards”.

Web services provide different challenges in managing access than what is presented by typical user based applications. In contrast to conventional access control approaches which employ static information system accounts and predefined sets of user privileges, many service-oriented architecture implementations rely on run time access control decisions facilitated by dynamic privilege management. While user identities remain relatively constant over time, user privileges may change more frequently based on the ongoing mission/business requirements and operational needs of the organization.

In contrast to conventional approaches to identification and authentication which employ static information system accounts for preregistered users, many service-oriented architecture implementations rely on establishing identities at run time for entities that were previously unknown. Dynamic establishment of identities and association of attributes and privileges with these identities are anticipated and provisioned. Pre-established trust relationships and mechanisms with appropriate authorities to validate identities and related credentials are essential.

This requirement is for web service based applications and is NA for databases.

Interpreting V-32458:

SQL Server does not use web services. Communication between servers can be done through various means, and there are other options to pay attention to when doing so. Options such as Cross database Ownership Chaining which lets one database reference objects in another so long as the object owners are mapped to the same login account.
