Juniper SRX Services Gateway ALG Security Technical Implementation Guide
SRG-NET-000362-ALG-000120
The Juniper SRX Services Gateway Firewall must implement load balancing on the perimeter firewall, at a minimum, to limit the effects of known and unknown types of Denial of Service (DoS) attacks on the network.
The Juniper SRX Services Gateway Firewall must implement load balancing on the perimeter firewall, at a minimum, to limit the effects of known and unknown types of Denial of Service (DoS) attacks on the network. An XCCDF Rule
The Juniper SRX Services Gateway Firewall must implement load balancing on the perimeter firewall, at a minimum, to limit the effects of known and unknown types of Denial of Service (DoS) attacks on the network.
Medium Severity
<VulnDiscussion>If the network does not provide safeguards against DoS attacks, network resources will be unavailable to users. Load balancing provides service redundancy, which reduces the susceptibility of the ALG to many DoS attacks.
This requirement applies to the network traffic functionality of the device as it pertains to handling network traffic. Some types of attacks may be specialized to certain network technologies, functions, or services. For each technology, known and potential DoS attacks must be identified and solutions for each type implemented.
The Juniper SRX provides a number of methods for load balancing the traffic flow. The device can be configured for filter based forwarding, per flow load balancing, per-packet load balancing, or High Availability (HA) using additional hardware. Since the firewall is considered a critical security system, it is imperative that perimeter firewalls, at a minimum, be safeguarded with redundancy measures such as HA.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
