00:00:00,230 --> 00:00:05,330
Hello and welcome to the network and Layer two attacks and Countermeasures course.

2
00:00:06,590 --> 00:00:09,980
Now, throughout the course, we're going to learn the following topics.

3
00:00:09,980 --> 00:00:14,540
First, we'll prepare the lab environment for hands on experiments.

4
00:00:14,570 --> 00:00:20,030
Second, we'll learn how to sniff the network and gather information from the network.

5
00:00:20,330 --> 00:00:24,020
We're going to use some tools such as Tcpdump and Wireshark.

6
00:00:24,050 --> 00:00:29,360
Then we'll see some attacks and techniques to expand the sniffing surface.

7
00:00:29,660 --> 00:00:37,400
Mac Address Table Overflow Attack, also known as Mac Flooding ARP Cache Poisoning Attack, also known

8
00:00:37,400 --> 00:00:39,200
as ARP Spoof.

9
00:00:40,150 --> 00:00:47,200
Dhcp starvation attack and Dhcp spoof and Vlan hopping techniques.

10
00:00:48,130 --> 00:00:55,720
The next topic is what else can be done on network devices in penetration tests, gathering information,

11
00:00:55,720 --> 00:01:00,100
cracking passwords of the communication channels, compromising SNMp.

12
00:01:00,130 --> 00:01:01,100
ET cetera.

13
00:01:01,510 --> 00:01:09,100
Finally, we'll check the configurations of the network devices, the password creation methods, identity

14
00:01:09,100 --> 00:01:13,690
management, access control lists, port security, and the list goes on.

15
00:01:13,930 --> 00:01:14,950
You with me?
