Hi Experts,
When we performed a security scan on our Cisco ISR 4351 Terminal router with reverse SSH and rotary feature used, it was observed that there were multiple open ports recognized ranging from 2001-20xx, 3001-30xx, 4001-40xx, 5001-50xx, 6001-60xx, 7001-70xx, 9001-90xx
Need to understand if these are the default ports enabled for terminal connections enabled with reverse SSH mechanism which the scan identified
Any relevant document which shows if these are default open ports and have no affect.
