‫Port Scan with end map allows you to discover which TCP or UDP ports are open on your target host.
‫Network ports are the entry points to a machine that is connected to the internet, a service that listens
‫on a port is able to receive data from a client application, process it and send a response back.
‫Malicious clients can sometimes exploit vulnerabilities in the server code so they can gain access to
‫sensitive data or execute malicious code on the machine remotely.
‫That is why testing for all ports is necessary in order to achieve a thorough security verification.
‫Port scanning is usually done in the initial phase of a penetration test in order to discover all network
‫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
‫types lectures.
‫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.
