Since Ganny.
And map as as target IP command.
Is the most commonly used form of scanning and unmap.
Of course, if we do not give a parameter while scanning and will always scan Tsipi.
So this can uses the aforementioned three way handshake system.
A second scan is faster and less detectable than a TCP scan because in this scan, the connection is
terminated before it's fully established.
However, you should also remember that they may be detected by next generation firewalls and security
software.
I'll show you how the scan works.
So step one and map will send a send packet to the scanned port of the target computer step to the computer,
receiving this response will send a sin act.
Step three, after receiving this answer and map does not send the packet from the computer that we're
scanning to complete the connection.
Instead, it sends a reset packet.
So that way, the possibility of logging is reduced and our speed increases as there is not a full connection.
Now, this type of scan is especially useful for systems that use firewalls, that way the status of
the corresponding port of the target is determined.
Ensign scanning comments are made according to the answers received, so when a scan is performed,
the following answers can be received from the target system.
The port open status.
So Unmap sends us in packet to the destination and the destination system sends this and packet.
And Map terminates the connection by sending a reset packet instead of sending an act back packet.
That indicates that the port is open and accessible and that the port accepts DCPI or UDP connection.
Port closed status.
And Map sends the send packet to the destination and the destination system sends a reset message instead
of the Sinak back at.
And then terminates the connection.
And in this case, the board is accessible but cannot be processed.
Now, how about the port filtered stats?
So two kinds of answers can be received here on the unmap side.
First, the unmap sends a send packet to the target system.
And no response is received from the target system.
When that happens, it is not commented whether the port on the target system is open or closed.
Then secondly, and maps tend to send packet to the target system and the destination system sends the
ICMP unreachable error packet.
So then in this case, the port is accessible, but it's not known whether it's open or closed.
