I. SNIFFING

The practice or
technique of
monitoring, gathering,
capturing, and logging
some or all data
packets passing
through a given
computer network is
called sniffing or packet
sniffing. A packet
sniffer is composed of
two parts namely; a
network adapter and
software that is used by a network to observe or troubleshoot network traffic.

Attackers use these sniffers to seize data packets that contain valuable
information and analyse the network traffic. Sniffing is categorized into active sniffing
and passive sniffing.

• In Active sniffing, there is the constant activity by the attacker to obtain
information and sniff the traffic from the switch network.
• In passive sniffing, the attacker is hidden and sniffs through the hub.
