What type of Virtual Private Network services can improve the online security for your data?

Oct 26, 2018 by

Internet connectivity has become as necessary as oxygen and water in our daily lives. We cannot imagine staying complete offline before critical deadlines, during ongoing projects and on the preparatory days before a conference. We take advantage of every Wi-Fi and open internet network we can find at airports, inside coffee shops and malls. During these times of desperation, we ignore the persistent threats of Wi-Fi spoofing, Firesheep and Honeypot Attacks. When working remotely on an unknown public network, you must always consider the possibility that an attacker is also on the network just waiting to breach.

We often use public networks to access company data on its private servers. If you discount the possibility of an attack, you are putting your company’s security, data and your job in danger. The only way to subvert the threat is by utilizing a virtual private network (VPN). A VPN allows the users to access private networks and share the data across multiple devices on any public network while minimizing the threats of data breaches. You can think of it as the online equivalent of your desktop firewall. In reality, it is a Wide Area Network (WAN) that retains identical functionalities and security of a private network.

Corporations prefer VPNs for establishing remote data sharing connections. They help in protecting the sensitive data from attackers. All VPNs use multiple encryption protocols in combination with dedicated connections, so even if hackers manage to get a slice of data, they are unable to unscramble it due to the encryption. Moreover, you can always fake your physical location while using a VPN server. A VPN server replaces the actual IP address of the user with a fake one. That allows the users to bypass content filters. For example – People in Germany may not have access to all the shows on Netflix that US users can watch. However, by using a VPN, the users in Germany can watch the same shows since the server spoofs their location.

Just like most modern technologies, VPN has several versions and features depending on the use of available technology. Over the last couple of years, several security protocols have evolved as Virtual Private Networks. Each one offers a unique set of services, but for every working VPN, you will need a few primary elements. There are several steps of setting up the VPN network that encompasses the client’s device, the cloud, network boundary, and enterprise networks. So, what do you need for setting up a VPN?

  • You need to establish a secure remote connection by using client VPN software.
  • You will also require routers and firewalls that can work with VPNs. It should be VPN-compliant, and it should allow the VPN traffic to pass through.
  • The network requires a concentrator, server, and VPN appliance to manage the incoming traffic to maintain the VPN sessions.

These are the three fundamental necessities of any basic VPN. Now, according to the specifications of the type of VPN you use, you might need to add or eliminate a few elements from the final list.

As we have said before, there are several types of VPNs, and the trick is to know which VPN to use. There are two main classes of VPN – client-based VPNs and network-based VPNs. Even they have many categories and sub-categories that meets the specific requirements of the user.

Client-based VPNs

It is the network between a remote network and a single user. To access a client-based network the user requires an application. The user can start the VPN client manually. That requires a verification of the username and password. It creates a tunnel between the remote network and the user’s device. The user can access the remote network via the encrypted tunnel.

The biggest advantage of having a client-based VPN application is the ability for your users to go online via their smartphones and laptops from any location. You can connect your iPhone, iPad, and Mac via the VPN client. If you are trying to access sensitive business data from your devices, you can always be sure that the connection is secure between your device of choice and the firewalls at the headquarters.

In most cases, the client software is free, but the VPN clients bear a price tag. The license requirement depends on the number of co-existing VPN connections that are there right now.

Network-based VPNs

The network-based connections are the virtual private networks that establish the connection between two individual networks dwelling on an untrusted network. There are multiple types of network-based VPNs, and you may have already come across at least one. Visit fastestVPNguide.com to find out more about the different types of the VPN services you should consider.

  1. IPsec Tunnels

The IP security or IPSec tunnels can secure internet communications. These may operate in one of the two modes. The Transport mode only encrypts the message in the data packet, and the Tunneling Mode encrypts whole packets of data. Most smart network users use IPSec Tunnels security in combination with other protocols for enhanced levels of security.

  1. Dynamic Multipoint VPN (DMVPN)

It is a secured network that facilitates data exchange between websites. DMVPN does not need the traffic to pass through the primary VPN server or router. This service leverages the VPN routers and firewall concentrators for operations. The dynamic multipoint VPN technology creates a mesh VPN landscape. So each website is capable of connecting with the others, irrespective of their current locations.

  1. MPLS-based VPN

Multi-protocol Label Switching (MPLS) technology allows data packets to go from source to their destination(s) by the use of labels. The MPLS technology does not use IP based forwarding methods. VPLS, Layer 3 VPN, and MVPN are all parts of the MPLS-based VPN technique. At the moment there are three most common MPLS VPNs in use – point to point, layer 2 MPLS VPN and Layer 3 MPLS VPN.

So, depending on your needs, you can pick one or multiple VPN services to safeguard your data. You can be a lonesome pirate or a data lord; you can always provide extra protection to your files by using virtual private network services.
