Answer 1

There are many methods by which you can monitor network traffic .

Below are some useful and important methods that we should know .

1)Firewall Monitoring

2)Vulnerability Scanning

3)Packet Sniffing

4)Intrusion Detection

Firewall Monitoring : By means of firewall we know that we can configure the traffic that can come and go within a network.So, we can set-up settings in our system in a way that we need only some pattern network to be allowed and remaining traffic has to be declined every time it reaches the network point.It tracks the every activity in our network. It monitors every function that is incoming and outgoing within a network.

Vulnerability Scanning : The vulnerability scan is used to detect the vulnerability activities that are currently running in a network.It is kind of detecting weak link before an attack can happen.So , we can use this scanning further to prevent the attack.It used to detect and classify the system weakness in a network.

Packet Sniffing : The Packet Sniffing ,as the name suggests , it reads and captures the every packet that crosses the network .The main purpose of Packet Sniffing is to detect the unauthorized network monitoring that is undergoing currently in a network.

Intrusion Detection : The Intrusion Detection is used to monitor the un-authorized activities that are performed by the hackers. It used to detect malware , virus and other network vulnerabilities.
