SA-11Developer Testing and Evaluation

Require the developer of the system, system component, or system service, at all post-design stages of the system development life cycle, to: Develop and implement a plan for ongoing security and privacy control assessments; Perform {{ insert: param, sa-11_odp.01 }} testing/evaluation {{ insert: param, sa-11_odp.02 }} at {{ insert: param, sa-11_odp.03 }}; Produce evidence of the execution of the assessment plan and the results of the testing and evaluation; Implement a verifiable flaw remediation process; and Correct flaws identified during testing and evaluation.

Weaknesses this control addresses (10)AI-assisted

CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE	Name	CVEs	Why this control addresses it
`CWE-119`	Improper Restriction of Operations within the Bounds of a Memory Buffer	14,500+	Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
`CWE-20`	Improper Input Validation	14,000+	Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.
`CWE-284`	Improper Access Control	6,900+	Explicit security control assessments verify proper access control enforcement, detecting weaknesses that the flaw remediation process then eliminates.
`CWE-74`	Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')	5,200+	Developer assessments and testing (including injection-focused techniques) identify improper neutralization of special elements, and the verifiable flaw remediation corrects them pre-deployment.
`CWE-287`	Improper Authentication	5,200+	Authentication mechanism testing and evaluation during development identifies bypass or weakness conditions, with mandatory correction prior to system delivery.
`CWE-400`	Uncontrolled Resource Consumption	3,800+	Resource consumption and denial-of-service testing performed under the assessment plan detects uncontrolled allocation paths that are subsequently fixed.
`CWE-502`	Deserialization of Untrusted Data	3,600+	Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
`CWE-754`	Improper Check for Unusual or Exceptional Conditions	700+	Security testing routinely checks for unusual or exceptional inputs/conditions, identifying missing validation steps that flaw remediation then resolves.
`CWE-693`	Protection Mechanism Failure	700+	Assessments of security controls directly validate whether protection mechanisms function as intended, exposing failures for correction.
`CWE-703`	Improper Check or Handling of Exceptional Conditions	100+	Testing and evaluation exercises error paths and exceptional conditions, surfacing improper handling that is then remediated through the defined process.
