Best Security Practices for Juniper (Junos OS ) on Management Plane

It is recommended to implement the separation of management and data/customer traffic in your Juniper devices (e.g. QFX Series Switches, MX Series).  Traffic passing through the management plane should be exclusively for management or administrative access purposes only like SSH, SNMP, NTP and AAA. Here’s the recommended configuration or practices for these management services. Configure Authentication, Authorization and Accounting (AAA) -preferably to setup centralized TACACS+ to manage all your devices, implement central network management that can impose security protocol to…

Configuring Network Time Protocol (NTP) the Secured way in Cisco Routers and Switches (IOS, IOS-XE, IOS-XR, NX-OS)

Cisco IOS e.g. Vlan10 =  interface management vlan NTP Server = 192.168.10.100 1. Configure ACL to deny NTP requests and query conf t access-list 100 remark to block NTP requests and query access-list 100 deny   any 2. Configure ACL to allow only the NTP servers to peer or synch with access-list 200 remark NTP to peer access-list 200 permit 192.168.10.100 access-list 200 deny  any 3. Configure NTP conf t ntp source Vlan10 ntp access-group peer 200 ntp access-group serve 100 ntp access-group…
