‫Port Scan with end map allows you to discover which TCP or UDP ports are open on your target host.

00:00:08,020 --> 00:00:14,230
‫Network ports are the entry points to a machine that is connected to the internet, a service that listens

00:00:14,230 --> 00:00:20,380
‫on a port is able to receive data from a client application, process it and send a response back.

4
00:00:21,250 --> 00:00:26,950
‫Malicious clients can sometimes exploit vulnerabilities in the server code so they can gain access to

5
00:00:26,950 --> 00:00:31,480
‫sensitive data or execute malicious code on the machine remotely.

6
00:00:32,320 --> 00:00:38,710
‫That is why testing for all ports is necessary in order to achieve a thorough security verification.

7
00:00:39,650 --> 00:00:45,920
‫Port scanning is usually done in the initial phase of a penetration test in order to discover all network

00:00:45,920 --> 00:00:47,750
‫entry point into the target system.

‫Port Scan takes the biggest part of our end map lectures in what I would call the most basic port scan

00:00:54,800 --> 00:00:55,970
‫types lectures.

11
00:00:56,000 --> 00:00:57,260
‫We see the following.

‫And map options of port scanning.

‫Since scan TCP scan comparison between the since scan and TCP scan, UDP scan and some other types of

‫port scans.
