Medium Severity
<VulnDiscussion>Failing to act on validation errors may result in the use of invalid, corrupted, or compromised information. The validation of bindings can be achieved, for example, using cryptographic checksums. Validations must be performed automatically. At a minimum, the application must log the validation error. However, more stringent actions can be taken based on the security posture and value of the information. The organization should consider the system's environment and impact of the errors when defining the actions. Additional examples of actions include automated notification to administrators, halting system process, or halting the specific operation. The DNS server should audit all failed attempts at server authentication through DNSSEC and TSIG/SIG(0). The actual auditing is performed by the operating system/network device manager, but the configuration to trigger the auditing is controlled by the DNS server.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
