As per new security Policy
(1) any unsuccessful or successful attempts to Core Backbone switches/routers should be logged and email alert goes to Security Team
(2) Any config changes including resetting of password should be logged and Email Alert goes to security Team
(3) Bandwidth Utilization more than 75% should send alert via email to IT Team
