The Juniper Networks SRX Series Gateway IDPS must restrict or block harmful or suspicious communications traffic between interconnected networks based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic.
Medium Severity
<VulnDiscussion>The IDPS enforces approved authorizations by controlling the flow of information between interconnected networks to prevent harmful or suspicious traffic does spread to these interconnected networks. Information flow control policies and restrictions govern where information is allowed to travel as opposed to who is allowed to access the information. The IDPS includes 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 external/perimeter boundaries. IDPS components are installed and configured such that they restrict or block detected harmful or suspect information flows based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic. Once an attack object in the IPS policy is matched, the SRX can execute an action on that specific session, along with actions on future sessions. The ability to execute an action on that particular session is known as an IDPS action. IDPS actions can be one of the following: No-Action, Drop-Packet, Drop-Connection, Close-Client, Close-Server, Close-Client-and-Server, DSCP-Marking, Recommended, or Ignore. IP actions are actions that can be enforced on future sessions. These actions include IP-Close, IP-Block, and IP-Notify This includes traffic between interfaces that are associated within the same security zone (intra-zone traffic). Traffic is permitted between security zones by configuring security policies from a source security zone to the destination security zone. 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>
