- Welcome to Lesson 17:
Active Reconnaissance,

2
00:00:10,120 --> 00:00:12,410
Scanning and Enumeration.

3
00:00:12,410 --> 00:00:16,530
This lesson starts by exploring
different scanning tools,

4
00:00:16,530 --> 00:00:21,530
learning about host, port
and service discovery.

5
00:00:21,660 --> 00:00:24,560
You will learn how to
perform banner grabbing

6
00:00:24,560 --> 00:00:26,850
and OS fingerprinting.

7
00:00:26,850 --> 00:00:29,530
This lesson teaches you how to scan

8
00:00:29,530 --> 00:00:33,710
beyond intrusion detection
systems and firewalls,

9
00:00:33,710 --> 00:00:37,330
as well as how to create
good network diagrams

10
00:00:37,330 --> 00:00:39,690
after your reconnaissance.

11
00:00:39,690 --> 00:00:42,840
You will learn different
enumeration techniques,

12
00:00:42,840 --> 00:00:46,550
how to perform NetBIOS, SNMP

13
00:00:46,550 --> 00:00:48,790
and LDAP enumeration.

14
00:00:48,790 --> 00:00:52,040
You will also learn how to perform NTP,

15
00:00:52,040 --> 00:00:53,320
NFS,

16
00:00:53,320 --> 00:00:54,730
SMTP

17
00:00:54,730 --> 00:00:56,650
and DNS enumeration,

18
00:00:56,650 --> 00:00:59,913
as well as conducting additional
enumeration techniques.
