Welcome to the lecture on the security of computer networks this time we will look at the issues associated
with the administration of computer networks in particular.
We will examine the methods of real time monitoring of packets sent over local networks and other networks
to where we use one of the most popular network monitoring tools Wireshark.
We will explore why automatic intrusion detection systems are not going to replace manual ways of network
traffic analysis and this module will answer the question how to control access to the network with
firewalls.
We'll get to know basic information about firewalls and their division.
We will also say a few words on network intrusion detection and the limitations of both technologies.
Then we will examine wireshark more closely and discuss its usefulness in detecting suspicious situations
that take place on computer networks.
Let's start.
