Step 1 - WhoIs

Step 2 - TCP Port Scanning

Step 3 - UDP Port Scanning

Step 4 - Analysis ---- Answer these questions:

• How can this type of scanning be used to help a network administrator protect a network?
• How can this type of scanning be used to harm a network?
• What did you learn from the results of these tests?

Answer 1

Hi, I would love to answer you with this question. I hope you will like an answer and get a clear idea related to the same. So not wasting much time let's get started.

Worry not I don't need you previous answer to help you with this.

The 4 part of the question is divided into three parts which are been answered as follows:

Ans.1 How can this type of scanning be used to help a network administrator protect a network?

• This type of port scanning which are TCP scanning and the UDP scanning can be used to protect a network as when a scanning is done whether TCP or UDP ports the results shows the the opened and the closed ports on the network or the IP been scanned with the services been used on those port numbers. When a network administrator uses scans through the network he get to know about the open ports and the services and those ports can be close or filtered so as to protect the network from the cyber attacks.

Ans.2 How can this type of scanning be used to harm a network?

• As we came to know above part of the question that the port scanning is been performed to gain the information related to the open ports and the services which results in the information gathering for a hacker or an attacker. And the hacker tries the exploits on these ports and try to gain access to the ports which are open. The different exploits which work on the open services are been tried and somehow manage to gain access to the system or the admin of the network

Ans.3 What did you learn from the results of these tests?

The following steps are been learned for the above answers and solutions

• No ports must be left opened
• No services must run without filtering the port
• The firewall must be enabled over the network
• Network admin must have a regular analysis over the network traffic
• Firewall must be configured with the proper IDS and IPS

I hope you have got your answers. Please do comment to ask for queries.
