The Juniper SRX Services Gateway Firewall must generate audit records when unsuccessful attempts to access security zones occur.
An XCCDF Rule
Description
<VulnDiscussion>Without generating log records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible for one. Access for different security levels maintains separation between resources (particularly stored data) of different security domains. The Juniper SRX Firewall implements security zones which are configured with different security policies based on risk and trust levels.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
