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.

Description
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 operationally practical. Juniper Networks recommends a best practice of 4 for the rate limit, however the limit should be as restrictive as operationally practical. User connections that exceed the rate-limit will be closed immediately after the connection is initiated. They will not be in a waiting state.

Who does this work

12 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-223234r961620_chk)

Verify the Juniper SRX sets a connection-limit for the SSH protocol. Show system services ssh If the SSH connection-limit is not set to 4 or an organization-defined value, this is a finding.

Fix Text (F-24895r513390_fix)

Configure the SSH protocol with a rate limit. [edit] set system services ssh rate-limit 4 Note: Juniper Networks recommends a best practice of 4 for the rate limit; however, the limit should be as restrictive as operationally practical.
