+SI-10(03) Predictable Behavior

SI-10(03) Predictable Behavior

Control

Verify that the system behaves in a predictable and documented manner when invalid inputs are received.

Discussion

A common vulnerability in organizational systems is unpredictable behavior when invalid inputs are received. Verification of system predictability helps ensure that the system behaves as expected when invalid inputs are received. This occurs by specifying system responses that allow the system to transition to known states without adverse, unintended side effects. The invalid inputs are those related to the information inputs defined by the organization in the base control ( [SI-10](#si-10)).

Assessment Objective

  1. the system behaves in a predictable manner when invalid inputs are received;
  2. the system behaves in a documented manner when invalid inputs are received.

Assessment Method

Examine

System and information integrity policy system and information integrity procedures procedures addressing information input validation system design documentation system configuration settings and associated documentation system audit records system security plan other relevant documents or records

Interview

Organizational personnel responsible for information input validation organizational personnel with information security responsibilities system/network administrators system developer
