Have you ever seen an error while connecting to a UK based website from the Australian domain? Sometimes, it shows error. A few websites don’t allow an access from the foreign ground. Terrorism, cyber- attack, privacy and many more reasons are there to do so.
But, it doesn’t mean that you can’t go there online. You can. If you have a VPN, it won’t be a Herculean task. Here, I’m specifically focusing on the remote access VPN.
Let’s begin with understanding what it is.
What is a Remote Access VPN?
As its name suggests, it is a connection that can be accessed from a remote site. It’s a secured connection with a computing device that is located remotely.
Let’s say, you work with an IT firm. And, your job-role takes you to the remote sites. These sites can be any other office premises or field. With this network, you can securely boot in to use the networked resources, like server and software etc..
This network has another name called Virtual Private Dial-Up Network (VPDN). It basically bridges the gap between the salesman, who has to visit the fields, and the main office. So, the expert IT consulting firms always recommend this network for a sales project.
Want to know how you can set it up in your office? Catch it below.
What do you need to have for setting up this network?
NAS (Network Access Server):
There are mainly two components that you should have. One is a Network Access Server or NAS. If it’s dedicated, you would have every reason to heave a sigh of relief. It’s just because of the fact that the dedicated server has no one to share it. You won’t have a third party to access your network unethically. Even, your network would be spacious and hacking-proof one.
If you won’t have deep pockets, the shared server can be a good choice. This kind of network might threaten security as there are many other users sharing the same network.
You need an internet connection in order to connect to any of these servers. You have to pass through authentication. You can sign up by feeding in requisite valid credentials. The individual hosts, like tele callers, mobile users and intranet users, can access it easily.
Client software:
To accept and address the request of booting from the network, you would need client software. If your employees or you yourself require linking through your system from hotel, cafeteria or home, you can do it through this client software.
Today, operating systems are available with inbuilt client software. But if, your system doesn’t have that software, you can install that specific application.
These two components together create an ideal network. Let’s look into how this combo sets up a network.
How does it work?
The client software creates a path to the NAS. Now, the host gains ability to send any information to the remote access VPN. In turn, the client software encapsulates and sends the information in an encrypted form over the internet.
To create this setup, the IT solution company uses IPsec approach. This approach enables encapsulating and encrypting the data. The two nodes, the host server and the client software, denote two endpoints on an IP network.
According to second approach, the IT networking engineer needs tunneling protocols. They allow the network user to get in and provide the network service that is not vulnerable directly.
Challenges:
1. Erratic access of voluminous data:
Distorted network is the biggest drawback of this kind of IT networking. If you compare the networking at your via a fiber with a shared wi fi connection, you’ll find several frictions in the remote access VPN network.
And, the distance is another barrier. If the far located client software undergoes any problem, controlling them is a hard nut to crack. Let’s say, you want to send a long video or voice over the IP address. This kind of data can be engrossed in this network’s bandwidth.
Result: The online delivery fails.
2. SSL VPNs:
The IPsec approach helps employees of an organization to connect irrespective of distance. They can browse their shared drives, applications and other assets as they usually do in the office premises. Their vulnerability emerges as a big security threat.
Contrary to that network, the SSL VPN provides vulnerability of a precise application or asset. Therefore, the networking engineer can proactively create a setup under SSL protocol. That limited access would have less chances of hacking.
3. SSL to embed IoT:
The camera, internet and sensors-fit devices are the major supplier of data over the internet. They collectively define IoT in the corporate sphere. It monitors and control systems that generate data together.
However, SSL protocol prevents from malicious attempts of hackers. But, IoT can’t be put under restrictions. It has to perform its function boundlessly. So, it’s one of the biggest challenges of this networking.
