While it is true that the use of technological resources benefit current work through networks, it is also true that we are therefore exposed to the information being stolen or hacked. This is why the Firewall becomes a key that restricts other computers from accessing the network data that you have and that Windows has integrated for that purpose.
This program allows your device to be less vulnerable to possible external attacks, protecting the information you have on your server, so that it is only you who authorizes devices to link to your host computer when configuring this resource.
It is important to highlight that it is an action that must be done with calm and with the precaution of having read in advance the steps for its activation, > if you want to conserve both the resources of the main equipment and the security of its correct operation. Below are the processes necessary to access it in an indicated manner. This will help you navigate safely and nothing you have is compromised.

What is the default port of the Remote Desktop in Windows?
It is nothing more and nothing less than a code, the TCD 3389 integrated in your Windows server. This computer resource will be the one who will receive the orders to link your use remotely through a configuration.
When you change the original encryption to this server, it will be protected from attacks and possible theft of information, thus providing high security. It is useful for networking that requires the use of several servers connected to a host computer . It should be noted that this sector can be considered vulnerable in terms of the amount of information that is handled and in those things that are confidential and require an exclusive interest of users.
However, this can also be used for personal utility, since it is so versatile that you can do an activity from another computer inside your home or any other place without the need to mobilize any equipment, only remotely commanded from a previous adjustment. This is integrated for Windows 10, 7 and 8, of similar execution for each version.
It is necessary to ensure that this new code is unique and not occupied by another server. You should also keep in mind that you must allow access to Firewall for the new security remote port code. In this case we must be the administrators of the main team that we want to modify.
It is advisable to make a backup of the registry and it is necessary to have basic knowledge to make the coding changes, because if it is not handled correctly the security of the equipment is compromised.
This remote desktop offers a kind of key to prevent other local computers with the same software from accessing. Similarly, it prevents them from doing so from the open internet connection .
