When it comes to handling the crucial task of system administration, the network administrator needs to be in touch with the client’s machine all the time. This ensures speedy resolution of any technical issue in the client’s system without affecting the business.
This feat can be accomplished by using a VNC (Virtual Network Computing) viewer. VNC viewer is a software program that can monitor the client’s machine remotely and assist them with the timely resolution of any software-related problem. Today we are going to unfold the concept of VNC viewer along with its implementation and functioning. Also, once you read this article, you will have a better knowledge of which VNC viewer to use in your business, and how.
What is VNC Viewer? [Difinition]
Let’s start with the definition of a VNC viewer. First, both VNC and VNC viewer are one term, so don’t get confused if we use them interchangeably. VNC is a cross-platform screen-sharing software program that is used for managing other computers remotely via the Internet. This means you can sit at your office and have control of the mouse, keyboard, and all the different functionalities of a remotely-located computer.
How VNC Functions
The working of VNC is dependent on the client/server model. As a result, to take control of the client’s system, you first need to install a server component on the remote machine. On the other side, a VNC viewer will be installed on your system through which you can access and handle the remotely-located computer. You can even use a tablet or mobile phone to access the client’s system.
When the connection between you and the client’s system is established, you can see the client’s screen on your desktop. You get complete control of the desktop when you get permission from the client’s side. Once you get the permission, you get to control the mouse and the keyboard of the client’s system as well.
Is it Safe to Use VNC?
As you have learned, VNC can allow a person to take control of your computer remotely. So it’s obvious to worry about the safety of your data if you allow anyone to take control of your system. Well, this can be avoided if you configure the VNC appropriately. One thing you need to know is that VNC is secure out of the box.
All the connections of VNC are end-to-end encrypted, and by default, the remote system is protected by a password for home subscription users. But when it comes to professional use, the remote system is protected by login credentials.
How to Make VNC More Secure?
If you still think there could be a threat of data breach, you can make VNC more secure by using the following security checks when making a connection with VNC.
- First, you should buy an enterprise version if you are working with a client or using it for business purposes.
- When creating a user ID and password for your VNC account, make sure you have chosen a complex password.
- A lot of VNCs now come with two-step verification, enabling them to receive OTP when you log in to the VNC from your account.
- Besides, make a group of systems to which you want to give specific permissions, don’t allow every system in the network to remotely access your computer.
- Use 256-bit AES encryption parameter on the VNC server and set it to Always maximum.
- Keep control of session permissions, restrict them according to your usage and make particular users get the ‘view only’ access.
- Make a habit of disconnecting idle sessions in the VNC server by reducing the time of IdleTimeout on the VNC server.
- In case you can be physically present during the time of connection, you should turn on the connection approval.
- Screen blanking should be used if a remote system is using the Windows operating system.
- Lastly, keep a regular check on connection audit logs of your VNC server.

If you are looking for a method to have remote access to your home computer all the time then you need to install UltraVNC. Though it is a good software for remote access, it is not the right VNC software for businesses as they can’t avail of remote technical support if the remote connection fails.

Also, you can skip using the program and access the server using a browser if you are working on a system that doesn’t allow you to install software programs in it. In short, UltraVNC is suitable for home usage, but not for business usage.
TigerVNC was created by RedHat to improve the functioning of their TightVNC. The TigerVNC’s development was kickstarted by taking a snapshot of the TightVNC code.

5. Chrome Remote Desktop
The Chrome Remote Desktop has become one of the most commonly used remote access applications. It is fast to set up, and when it comes to using the interface, even a student can perform all the tasks with ease. Chrome Remote Desktop is enough for you if you are looking to make a remote connection to your own devices or helping out a friend or family to fix their computer.
However, if you are thinking about using this tool for business, then it’s not the right choice as it has limited features. It doesn’t come with the inbuilt chatbox, and to use this tool, you need to have a Chrome browser. Also, there is no drag-and-drop option for sending the files from your system to the remote desktop, which sometimes is a basic necessity when you are working with a client. There is no automatic reconnect option, so the person on the remote computer needs to start the connection again manually. Thus, we prefer this VNC software for home usage only.
