The Juniper Networks SRX Series Gateway IDPS must enforce approved authorizations by restricting or blocking the flow of harmful or suspicious communications traffic within the network as defined in the PPSM CAL and vulnerability assessments.
The Juniper Networks SRX Series Gateway IDPS must enforce approved authorizations by restricting or blocking the flow of harmful or suspicious communications traffic within the network as defined in the PPSM CAL and vulnerability assessments. An XCCDF Rule
The Juniper Networks SRX Series Gateway IDPS must enforce approved authorizations by restricting or blocking the flow of harmful or suspicious communications traffic within the network as defined in the PPSM CAL and vulnerability assessments.
Medium Severity
<VulnDiscussion>The flow of all communications traffic must be monitored and controlled so it does not introduce any unacceptable risk to the network infrastructure or data.
Restricting the flow of communications traffic, also known as Information flow control, regulates where information is allowed to travel as opposed to who is allowed to access the information and without explicit regard to subsequent accesses to that information.
The IDPS will include policy filters, rules, signatures, and behavior analysis algorithms that inspects and restricts traffic based on the characteristics of the information and/or the information path as it crosses internal network boundaries. The IDPS monitors for harmful or suspicious information flows and restricts or blocks this traffic based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic.
The PPSM CAL addresses internal network boundaries restrictions based on traffic type and content such as ports, protocols and services. The Juniper SRX denies all traffic.
IDPS inspection will only be performed on the traffic matching the security policies where IDPS is enabled.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
