00:00:00,360 --> 00:00:06,680
What is passive reconnaissance, so passive reconnaissance involves gathering information about like

2
00:00:06,690 --> 00:00:11,200
a target or target network without actually, you know, connecting to them at all.

3
00:00:11,370 --> 00:00:15,570
You know, typically passive reconnaissance involves using, you know, intelligence.

4
00:00:15,570 --> 00:00:20,580
You might have seen this on the Internet somewhere as U.S. and you're using that to gather information

5
00:00:20,580 --> 00:00:21,340
about your target.

6
00:00:21,570 --> 00:00:26,490
So it just means that you're pretty much going to utilize any publicly available information that you

7
00:00:26,490 --> 00:00:31,020
can find on the Internet to formulate your attack, which is actually illegal because it's publicly

8
00:00:31,200 --> 00:00:31,820
available.

9
00:00:32,100 --> 00:00:37,530
And, you know, this allows you to not be detected while you're gathering very useful information.

10
00:00:39,640 --> 00:00:45,670
So what is active reconnaissance then, active reconnaissance actually involves gathering information

11
00:00:45,670 --> 00:00:51,010
about the target while initiating connections, you know, to them you're actually going to be contacting

12
00:00:51,160 --> 00:00:51,960
this target.

13
00:00:51,970 --> 00:00:57,700
Typically, active reconnaissance involves using a variety of tools, like maybe a port scanner or a

14
00:00:57,700 --> 00:01:01,090
vulnerability scanner or something to gather information.

15
00:01:01,310 --> 00:01:06,190
Now, this allows you to gather more useful information and a lot more sensitive information.

16
00:01:06,200 --> 00:01:08,710
But it's going to allow you to also be detectives.

17
00:01:08,720 --> 00:01:11,740
You have to be very, very careful when you do an active reconnaissance.
