DCP scam so in our previous lessons we discussed the DCP scam by default and map always perform this

2

DCP scans and mice otherwise specified.

3

So let's take a closer look at DCP scan within map and map sends a sin packet to the target system and

4

the target system receives the packet and sends the send act packet to the end map.

5

Computer which receives and map packet and sends the ACT packet to complete the connection the destination

6

system port sends the port information that is open then map terminates the connection by sending a

7

reset packet immediately so to scan TCB with n map we need to add the s t parameter to the N map command

8

I'll give you an example we'll scan the TTP top twenty on the Metis portable server that we install

9

so open virtual box open Kelly Linux open Metis portable and log in Cowley Linux v Ms open up terminal

10

and write the command and map ten to zero dot two dot for top port twenty press enter and the results

11

of the scan are right here so let's have a look.

12

As you can see the top 20 ports were scanned and it was the result

13

DCP and since scan difference so yeah.

14

Okay.

15

So what are the differences between the since scan and the DCP scan the right here since scan three

16

way handshake does not complete the DCP scan the three way handshake is complete this in scan if this

17

in ACH packet arrives the connection is terminated with reset then on a DCP scan if this snack packet

18

arrives the connection is completed with the back packet and it's in scan since scans are usually not

19

logged on a server DCP scan are logged on the server since scans require root authority because there

20

was interference in the packet is at DCP scan does not require any route privileges because it uses

21

the DCP connect method.
