sc-39(2)

process isolation  | thread isolation

assessment objective:

Determine if the information system:

sc-39(2)[1]

defines multi-threaded processing for which a separate execution domain is to be maintained for each thread in multi-threaded processing; and

sc-39(2)[2]

maintains a separate execution domain for each thread in organization-defined multi-threaded processing.

potential assessment methods and objects:

Examine: [SELECT FROM: System and communications protection policy; information system design documentation; information system configuration settings and associated documentation; information system architecture; list of information system execution domains for each thread in multi-threaded processing; information system documentation for multi-threaded processing; information system documentation from vendors, manufacturers or developers; independent verification and validation documentation; other relevant documents or records].

Interview: [select from: System/network administrators; organizational personnel with information security responsibilities; system developer; organizational personnel installing, configuring, and/or maintaining the information system; information system developers/integrators].

Test: [select from: Information system capability implementing a separate execution domain for each thread in multi-threaded processing].
