00:00:06,826 --> 00:00:10,373
- Welcome to Lesson 8:
Hacking Networking Devices.

2
00:00:10,373 --> 00:00:12,658
In this lesson we'll
start with looking at why

3
00:00:12,658 --> 00:00:15,544
network devices are a target
for hackers, followed by

4
00:00:15,544 --> 00:00:19,035
reviewing the fundamentals
of networking technology.

5
00:00:19,035 --> 00:00:23,161
This includes the OSI and DoD
Internet Reference Models,

6
00:00:23,161 --> 00:00:27,423
ethernet, routers, switches, firewalls and

7
00:00:27,423 --> 00:00:29,856
networking security products.

8
00:00:29,856 --> 00:00:31,726
We'll review the different
planes of network

9
00:00:31,726 --> 00:00:34,022
devices, such as the data plane, control

10
00:00:34,022 --> 00:00:36,568
plane, and management plane.

11
00:00:36,568 --> 00:00:38,565
You'll learn about local attacks against

12
00:00:38,565 --> 00:00:40,995
switches and broadcast domains, or virtual

13
00:00:40,995 --> 00:00:44,009
LANs, including attacks against VLAN

14
00:00:44,009 --> 00:00:48,406
Trunking Protocol, or VTP,
and ARP cache poisoning.

15
00:00:48,406 --> 00:00:51,216
Then we'll extend our
attacks into routers,

16
00:00:51,216 --> 00:00:54,149
first-hop redundancy
protocols and interior gateway

17
00:00:54,149 --> 00:00:58,495
protocols, such as OSPF or
open shortest path first,

18
00:00:58,495 --> 00:01:00,610
including how to use
these tools to pull off

19
00:01:00,610 --> 00:01:02,392
man-in-the-middle attacks.

20
00:01:02,392 --> 00:01:05,801
We have a lot to cover,
so let's get started.
