1. What is remote access?
What is remote access? Remote access refers to the ability of an authorized user to remotely access a computer from other devices located in a remote location. A user can access resources stored on another computer or network, and even take full control of it if granted remote access.
Remote access brings convenience to our life. Different people use remote access for different purposes to remotely access computer files, mobile phones to remotely access computer files, etc.
2. The composition of remote access
After understanding what remote access is, let's talk about the composition of remote access. In all remote access connections, remote access generally has three main components:
- Remote Access Server: It is a server in the organization's network that is the destination for all remote access connections.
- Remote Access Client: All computers that are remotely connected to the network, known as remote access clients or remote computers.
- Communication type and infrastructure: including VPN, cloud service, remote desktop, third-party software, etc.
3. What are the methods of remote access?
Remote access can be realized in many different ways, here we will introduce three common remote access methods: remote access software, virtual private network (VPN), cloud service.
1. Remote access software
What is Remote Access Software? Remote access software can connect to computers in another place through an internal network or the Internet, allowing them to view and operate it with each other, using remote access software you can browse or transfer files, and solve computer problems, etc.
There are various types of remote access software, some are paid and some are free. The more widely used remote access software is the built-in remote desktop of Windows, which remotely controls the computer through the IP address and user name of the remote computer.
2. Virtual Private Network (VPN)
A Virtual Private Network (VPN) primarily establishes a secure Internet connection between users and networks through advanced encryption and tunneling technologies. The reason why it is called a virtual network is that the connection between any two nodes of the VPN is based on the network platform provided by the public network service provider.
In short, your traffic data is transmitted through a secure channel to your internet provider's VPN server. Through this server, your encrypted data, hidden geographical location, and IP address are all sent to the website you want to browse, allowing you to achieve remote access. Note, however, that in contrast to remote access software, using a VPN will only give you access to shared resources on the same network, not control over other devices.
3. Cloud service
Companies that provide cloud services enable users to store files and applications on remote servers and then access all data over the Internet. With cloud solutions, data files can be downloaded to remote computers. This means users don't need to be in a specific location to access it, allowing users to work remotely.
Likewise, cloud services only allow you to access data that is already stored on remote servers. Using remote desktop software, you can access a specific desktop, files, applications, and everything else related to that desktop from a remote location. So, even though cloud services provide a form of remote access, it's still no substitute for remote access software.
4. What are the advantages and disadvantages of remote access?
Key advantages of remote access :
- Save time: Remote access allows you to access company computer files at home or transfer files without spending time traveling from home to the office.
- Break the space limitation: With remote access, even if you are on a business trip, you can remotely access your office computer.
- Cost saving: Remote access breaks the limitation of time and space, helping you save travel expenses.
Of course, remote access also has its disadvantages :
- Security Concerns: Remote access can introduce other vulnerabilities that can be used as attack points, which makes it easy for attackers to infiltrate the system.
- Network dependency: The remote access experience depends largely on the speed of your network.
5. Extended reading: remote access software recommendation
AnyViewer is a free and easy-to-use remote desktop software, which uses elliptic curve encryption (ECC) to protect your data from being leaked. You can use AnyViewer to remotely access the company computer for office work, remotely transfer files, remotely shut down the computer, etc. Next, we will introduce you how to use AnyViewer for remote access.
