Introduction
VPN services provide a secure and encrypted connection, which can help remaining anonymous and prevent cybercriminals from accessing content. Virtual private network (VPN) services also allow users to surf the Internet safely and e-mail without having to worry about geo-restrictions. VPNs can be used to connect one’s PC or server directly to the internet. The user also does not need a VPN for this, assuming that the router can create at least one “private network”.
Typically, a VPN is used over a less secure network, such as the public internet. Internet service providers (ISPs) normally have a rather large amount of insight into a customer’s activities. In addition, some unsecured Wi-Fi access points (APs) may be a convenient avenue for attackers to gain access to a user’s personal data. An internet user could use a VPN to avoid these encroachments on privacy.
VPNs can be used to conceal what a VPN user does, and thus allow you to access information and behave as if they are somewhere else.
A VPN is a useful tool in securing sensitive data and ensuring confidentiality of your activity on both your personal and corporate account.
VPN apps can be used to visit websites that are restricted by location. They should not be confused with secure access through a mobile VPN app. What they can and cannot do is to turn off WiFi and connect to WiFi slowly in order to make it seem like the security of your connection is much better than it actually is. Private browsing does not involve encryption; it is a browser setting.
How do VPNs work?
At its most basic level, VPN tunneling creates a point-to-point connection that cannot be accessed by unauthorized users. The tunneling system is used to provide secure communications between different VPNs or in instances in which access to another network is prevented by firewall restrictions. The tunneling protocol used may depend on the platform the VPN is being used on, such as SSTP being used on Windows OS, and will provide data encryption at varying strengths. The endpoint device needs to be running a VPN client (software application) locally or in the cloud. The client will run in the background. The VPN client is not noticeable to the end user unless it creates performance issues.
The kill switch comes in handy if the connection is disrupted. When you connect to the VPN, the system automatically disconnects from the network once its integrity has been compromised.
There are two types of kill switches:
-
Active kill switch protocols prevent devices from connecting to unsafe networks when the device is connected to the VPN. Apart from server disruptions, it is disabled when not connected to the VPN.
-
Passive kill switch protocols are more secure. They keep the device from connecting to non-VPN connections even while disconnected from the VPN server.
VPN protocols
VPN protocols ensure an appropriate level of security to connected systems when the underlying network infrastructure alone cannot provide it. Several different protocols can be used to secure and encrypt data. They include:
-
IPsec.
-
Secure Socket Layer (SSL) and Transport Layer Security (TLS)
-
Point-to-Point Tunneling Protocol (PPTP))Point-to-Point Tunneling
-
)Point-to-Point Tunneling Protocol (PPTP)
-
Layer 2 Tunneling Protocol (L2TP)
-
OpenVPN
Benefits and challenges of using a VPN
Benefits of using a VPN include the following:
-
Employers will be able to provide information about browsing habits of workers on the behalf of the employees. A worker’s own browsing history is not available on their social media accounts, which can be viewed by their employer. This method can help with prevention & better monitoring of workers’ Internet behavior.
-
secure connections between users and machines
-
bypassing geo-blocked content; and
-
making it more difficult for advertisers to target ads to individuals.
The challenges of using a VPN, however, include the following:
-
Not all devices may support a VPN.
-
VPNs do not protect against every threat.
-
Paid VPNs are more trusted, secure options.
-
A VPN may slow down internet speeds.
Types of VPNs
Network administrators have several options when it comes to deploying a VPN that include the following.
Remote access VPN
The VPN gateway is used to establish a secure tunnel from the user’s device through the VPN. This allows access from all locations to your organization’s data irrespective of location or firewall restrictions existing in the organization’s network. Security and prevention knowledge The gateway requires the device to authenticate its identity before granting access to internal network resources. This type usually relies on either IPsec or SSL to secure the connection.
Site-to-site VPN
A site-to-site VPN ensures that company engineers are in their office, but allows them to access the internet when outside their office. End-node devices in the remote location do not need VPN clients because the gateway handles the connection. Most site-to-site VPNs connecting over the internet use IPsec. VPNs are becoming more common at work, but for many reasons. These include security issues, concerns about costly bandwidth pricing, and the possibility that they could change the security of your network Using a MPLS VPN service it is possible to have Layer 3 technology running across the transport links. This technology ‘automatically’ looks for Layer 3 access points i.e. active interfaces
Mobile VPN
In a mobile VPN, the server still sits at the edge of the organization’s network, enabling secure tunneled access by authenticated, authorized clients. Mobile VPN tunnels are not tied to physical IP addresses, however. Instead, each tunnel is bound to a logical IP address. That logical IP address stays to the mobile device. An effective mobile VPN provides continuous service to users and can switch across access technologies and multiple public and private networks.
Hardware VPN
Hardware VPNs can provide load balancing and internet performance for many small and mid-size businesses and offices.. Administration is managed through a web browser interface. A hardware VPN is more expensive than a software-based one. Because of the cost, hardware VPNs are more viable for larger businesses. Several vendors offer devices that can function as hardware VPNs.
VPN appliance
VPNs are used to establish secure communication channels between computer networks. The VPN gateway appliance serves as an endpoint that listens both on the public Internet and on other private intranets, while encrypting all data along the way.
Dynamic multipoint virtual private network (DMVPN)
A DMVPN can allay organizational security issues because it does not rely on the headquarters. It’s a mesh VPN service that should be able to run across any common router or network firewalls. Connecting through the router, each employee’s workspace will appear like a small cluster of nodes connected by Internet, which is physically located at the company headquarters. When two spokes are required to exchange data between each other — for a voice over IP (VoIP) telephone call, for example — the spoke will contact the hub, obtain the needed information about the other end and create a dynamic IPsec VPN tunnel directly between them.
VPN vendors and products
VPN services are available as free or paid options. Paid vendor options tend to be recommended more often than free ones, however. Some VPNvendors, among many, include the following:
-
NordVPN contains a strong collection of security features with a large collection of servers. NordVPN has strong privacy policies in place so it enhances your internet security. It is one of our favorite VPNs due to it’s service quality, user experience and most importantly its feature set/availability
-
Private Internet Access VPN is an app for iOS and Android that can support up to 10 different simultaneous connections. It does not offer too much in terms of extra features and privacy tools, however. Still, it is generally considered a good VPN service.
-
ExpressVPN is a VPN service with a large and diverse set of distributed servers. It has strong privacy and information practices focused on security and offers extra features such as split tunneling. It also uses the OpenVPN protocol.
How to choose a VPN
VPNs are legal in the United States, but users and organizations should check if they are legal in specific countries.
Many VPNs offer extremely similar technologies, so it can be hard to choose which VPN will work best. Paid VPN services tend to be more trusted and include more security features. Reputable VPN services will be upfront about their security, their strengths and weaknesses, and their transparency by releasing third-party audits, for example. Extra VPN features include split tunneling, access to the Tor network or multihop connections.
Once individuals look at the added features and find a service they think will work for them, it’s a good idea to start out with a short-term subscription. Many vendors offer free trials of their paid versions. Some free trial versions may include a limit on how much data can be used.
