Fuss no more: securely access VNC from outside the network
Navigating beyond borders or seas, today's businesses thrive in a landscape unconfined by the office or home walls. As companies adapt to this new dynamic, Virtual Network Computing (VNC) emerges as a practical tool to bridge different networks. While VNC is convenient, using it solo isn't enough – it calls for extra security measures to protect against potential threats. That's where NordLayer steps in, enhancing your VNC experience with assured security, keeping your network well-guarded & robust.
OVERVIEW
What is Virtual Network Computing (VNC)?
It is a system that enables remote computer control. VNC uses a simple client-server model, allowing users to operate hardware from a remote server. With this model, users can observe the operating system, run programs, and access connected devices like printers and external drives, providing a seamless experience for remote & local operators with a strong internet connection.
OPERATION
And how does VNC work?
VNC employs the Remote Frame Buffer protocol (RFB) to establish graphical desktop-sharing capabilities, transmitting keyboard and mouse inputs between computers over a network. It operates across multiple GUI-based operating systems and Java, allowing multiple clients to connect to a VNC server simultaneously. Popular applications of VNC include remote technical support and accessing work files from home computers or vice versa.Â
For businesses, VNC serves two main functions: enabling long-distance technical support and facilitating remote working by providing complete access to office desktops without software or permission restrictions.
RISKS
Is VNC secure?
It largely depends on the specific software used and the protective measures taken. Despite its convenience, VNC can introduce risks due to inconsistent encryption levels and usage on insecure networks. Understanding these vulnerabilities is paramount when using VNC for remote data access.
VNC access from external sources can introduce vulnerabilities, potentially compromising the security of your data.
The availability of different VNC clients and servers means security levels vary. While some implementations encrypt passwords, weaknesses in the process can allow skilled adversaries to intercept them.
Not all VNC applications provide robust encryption. It's important to carefully review your chosen VNC software to ensure it offers adequate security measures.
Without proper security measures, unauthorized individuals may attempt to gain access to your VNC sessions, potentially exposing sensitive information and compromising your systems.

Access to virtual desktops (DaaS, VDI, hosting)
In a sly maneuver called hyperjacking, cyber attackers can use malware to seize control of the hypervisor, stealthily gaining access to all resources and permissions linked to the server.
Remote file transfer
VNC's file transfer feature is widely used, yet without adequate protection, this process can be compromised. Unauthorized parties may intercept and misuse the information, leading to potentially disastrous consequences.
Remote technical support
VNC is a popular solution for resolving technical issues due to its convenience. However, granting network access to a third party inherently introduces additional security considerations.
Business Continuity Processes (BCP)Â
VNC proves indispensable for remote access in dispersed work setups or during unexpected events. Still, this broad access can heighten cybersecurity risks if not diligently secured, offering possible entry points for unauthorized users.

Frequently asked questions
Virtual Network Computing (VNC) and Virtual Private Networking (VPN) serve distinct purposes, although they sound similar. VNC allows for remote computer control, enabling users to operate it as if they were sitting directly in front of it. This includes access to resources like printers and network drives available on the remote machine. Conversely, a VPN doesn't provide a remote desktop. Instead, it connects your computer to a remote network, allowing you to access its resources from your own desktop. In essence, while a VPN incorporates your computer into a remote network, VNC enables viewing and control of a remote computer. VNC facilitates remote working but doesn't offer the same level of privacy and security inherent in a VPN, such as the end-to-end encryption provided by NordLayer. These tools can, however, work effectively in tandem for a secure remote-working infrastructure.
No, it’s not. Security varies significantly across different VNC clients and servers due to a wide range of available options. While the base RFB protocol does encrypt passwords, inherent weaknesses may allow these passwords to be intercepted by a skilled adversary. Furthermore, not all VNC implementations ensure total connection encryption. For example, TightVNC only encrypts passwords weakly and doesn't encrypt the remainder of the session at all. This lack of robust encryption, particularly when used on insecure networks like vulnerable home routers or public Wi-Fi, exposes private files, passwords, and databases to serious security risks. Therefore, reviewing the VNC application’s security features is crucial to ensure it meets the necessary security requirements.
It is a simple, open protocol used to facilitate remote control of computer systems. It operates at the framebuffer level, directly interacting with the graphical data that represents what is displayed on a computer screen. This protocol is widely used in Virtual Network Computing (VNC), allowing for the seamless transmission of graphical interfaces across different operating systems, including Microsoft Windows, macOS, and the X Window System. Despite its simplicity, RFB negotiates mutual functionality levels between devices to maintain compatibility and has been continually enhanced to support advanced features and improved security measures.
