SA-15(05) Attack Surface Reduction
Control
Require the developer of the system, system component, or system service to reduce attack surfaces to [Assignement: thresholds].
Discussion
Attack surface reduction is closely aligned with threat and vulnerability analyses and system architecture and design. Attack surface reduction is a means of reducing risk to organizations by giving attackers less opportunity to exploit weaknesses or deficiencies (i.e., potential vulnerabilities) within systems, system components, and system services. Attack surface reduction includes implementing the concept of layered defenses, applying the principles of least privilege and least functionality, applying secure software development practices, deprecating unsafe functions, reducing entry points available to unauthorized users, reducing the amount of code that executes, and eliminating application programming interfaces (APIs) that are vulnerable to attacks.
Assessment Objective
the developer of the system, system component, or system service is required to reduce attack surfaces to [Assignement: thresholds].
Assessment Method
Examine
System and services acquisition policy
procedures addressing development process, standards, and tools
procedures addressing attack surface reduction
solicitation documentation
acquisition documentation
service level agreements
acquisition contracts for the system or system service
system design documentation
network diagram
system configuration settings and associated documentation establishing/enforcing organization-defined thresholds for reducing attack surfaces
list of restricted ports, protocols, functions, and services
system security plan
other relevant documents or records
Interview
Organizational personnel with system and service acquisition responsibilities
organizational personnel with information security responsibilities
organizational personnel responsible for attack surface reduction thresholds
system developer
