The Juniper SRX Services Gateway must terminate a device management session after 10 minutes of inactivity, except to fulfill documented and validated mission requirements.
Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session. Quickly terminating an idle session also...Rule Medium Severity -

The Juniper SRX Services Gateway must configure the control plane to protect against or limit the effects of common types of Denial of Service (DoS) attacks on the device itself by configuring applicable system options and internet-options.
DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity. Juniper SRX ...Rule Medium Severity -

The Juniper SRX Services Gateway must limit the number of sessions per minute to an organization-defined number for SSH to protect remote access management from unauthorized access.
The rate-limit command limits the number of SSH session attempts allowed per minute which helps limit an attacker's ability to perform DoS attacks. The rate limit should be as restrictive as operat...Rule Medium Severity -

The Juniper SRX Services Gateway must implement service redundancy to protect against or limit the effects of common types of Denial of Service (DoS) attacks on the device itself.
Service redundancy, may reduce the susceptibility to some DoS attacks. Organizations must consider the need for service redundancy in accordance with DoD policy. If service redundancy is required ...Rule Low Severity -
