19 items · Security · Hard difficulty · 1 day

Practical steps to harden Juniper routers and maintain STIG compliance.

• Download the Juniper Router STIG package (XCCDF/HTML/PDF)

  Get the latest STIG (Y25M01 or current) from DISA IASE or official resource.

• Review STIG controls and map to your environment

  Identify applicable controls, exceptions, and implementation scope.

• Inventory Juniper devices and record JunOS versions

  Capture device model, OS version, location, and management IP.

• Run automated STIG compliance scan (XCCDF/SCAP)

  Use approved scanners and save the generated report for review.

• Apply vendor-recommended patches and JunOS updates

  Patch devices to versions that address known CVEs and fixes.

• Implement STIG baseline configuration on routers

  Apply STIG-required settings: interfaces, services, logging, and accounts.

• Secure management access
• Enable SSH v2 and disable Telnet

  Configure SSH v2 only and remove unsecured management protocols.

• Restrict management access to trusted IPs or management VRF

  Limit which hosts/networks can reach device management interfaces.

• Enforce role-based admin accounts and disable default accounts

  Create least-privilege roles and remove or disable shared/default logins.

• Disable unused services and protocols

  Turn off services like FTP, rsh, finger, and other unused daemons.

• Configure strong authentication and password policies

  Set complexity, aging, history, and account lockout policies.

• Harden SNMP: use SNMPv3, restrict access, and change community strings

  Use authenticated/encrypted SNMP and limit collectors by ACL.

• Configure NTP and lock time sources

  Use trusted NTP servers and restrict NTP service to authorized hosts.

• Enable and centralize logging to a secure syslog/SIEM

  Forward logs to a protected collector with retention and integrity controls.

• Deploy firewall filters and ACLs for control-plane protection

  Apply anti-spoofing, management ACLs, and control-plane policing.

• Perform STIG compliance re-scan and save results

  Re-run automated checks to validate applied hardening.

• Document deviations and submit Risk Acceptance (DAA) requests

  Record justified exceptions and obtain formal approval where needed.

• Schedule periodic audits and subscribe to DISA IASE updates

  Set recurring reviews and watch for STIG or reference updates.
