ESP Grade A Analysis


1st - 1723 is a standard port number for a VPN on more general basis. Using a 1720 port is more commonly used for calling services.

2nd - DENY allows or denies all the traffic from a network IP address. It needs to be at the bottom of the table or the top. It will create conflict if it is in the middle (traffic lose).

3rd - UDP is changed to TCP on the VPN as the traffic must be checked whether or not it has been received. UDP does not check whether the traffic has been received or not.

4th - The change makes perfect sense as pointing to a random workstation would mean none of the services would work. The services are running on the server so they need to be pointing at the server.

How to make it better 

  • Add external IP’s, this should be the same as the internal IP   
  • Change the port of POP3 from 143 to 110 due to 143 being the port for IMAP.  
  • Only use wildcards if you need to as they leave the network exposed as any external IP could gain access to it.  
  • Use HTTPS as well as HTTP as it is not secure

Task 2

This person has missed out the email to the technical audience, the email that they did write is very good. 
In the interview the student has shown a good understanding of his technical skills.
The questions the student laid out are good. 

Task 3

More explanation surrounding why exactly specifically he has chosen the Fortinet brand. As there is also a subscription that could potentially be avoided. 

For upgrading to the new version of Windows Server, he has not given any alternatives for an operating system. He has also not given an disadvantages to using Windows Server.

He hasn't given alternatives for the email software

Conclusion

In general this student did I pretty good job examining this business' network. In task 1 he correctly identified

Global RTS The trip was in the morning on the 28th March 2025, Will and Patrick organised it. The purpose of the trip was to gain experience in the aviation industry, specifically air traffic control, using a simulator. We were shown how there simulators work and we were shown how to use them as well as being able to communicate using the aviation alphabet. We met people who worked there, learning how to become an air traffic controller. We used there main sim that used 4 big TVs to show a graphically simulated view of a run way from the view of a tower. We also communicated with headsets to simulate how real air traffic controllers communicate to pilots.
