This document provides an overview of network management, monitoring, and security. It discusses the importance of network maintenance for keeping a network operational and minimizing downtime. Network monitoring software helps diagnose problems, gather statistics, and monitor the health of the network environment. Various network attacks are outlined as well as defenses such as firewalls and encryption. Bring-your-own-device policies present security risks that can be mitigated with device management, clear policies on data ownership, and exit strategies for employees.

•Providing network availability and security
•Saving expenses for the network as it can minimize the
downtime of the network
•Planning the maintenance activities
•Implementing the maintenance activities planned and
those unforeseen
•Optimizing the network capability, reliability,
performance, consistency and longevity

6. Assumption
Network maintenance is very essential as the followings.
Need to have running up the network very smoothly for
our customers
Before users are affected, it can monitor the network spot
the problem very quickly
Repairs and upgrades are also concerning for network
maintenance

7. Assumption
Network maintenance is very essential as the followings.
A crucial component of keeping your network operational by
maintaining our network
