4G vs. Wi-Fi: Which is the Safest Way to Surf?

The increasing use of smart phones has consequently increased the demand for 3G, 4G connection, and Wi-Fi hotspots. Although you could choose from any of these options to stay connected and browse the Web, finding the most secure one is a difficult task. It is also important to understand these technologies and the risks involved with the same, before making a choice.

Understanding connectivity options

·         4G Connections
When 4G devices are connected to a cellular company’s network connection, they receive data from the cellular company, enabling them to connect to the Web. Therefore, when you use 4G, you could access the Web whenever you receive a signal. Moreover, since the data being transferred via the network is encrypted, 4G is a safer option than public Wi-Fi hotspot.

·         Public Wi-Fi hotspots
Public hotspots are generally found in coffee shops, airports, malls, and several other places. However, you may not be able to ascertain whether it is safe or not from hackers who may try to breach your device’s security. It is a viable option only if your phone is secured through a virtual private network (VPN), wherein your device’s information is strongly encrypted.

·         Private Wi-Fi connections
A private Wi-Fi connection is what you probably have installed at your home or office. This connection, when setup appropriately and secured with a strong password encrypts the data being transferred and received. Only authorized individuals may access this network through a password.

Security level on a 4G network
With regard to 4G, the hacking has mainly been restricted to the proof-of-concepts stage. This is a situation wherein white hat hackers attempt to infiltrate a network for research purposes.
There have been instances when individuals have hacked 4G through man-in-the-middle (MITM) attacks, wherein the unauthorized individuals place themselves between an app and a user or even between two unsuspicious people to ‘listen in’ on the transmissions being sent. However, compared to public Wi-Fi hotspots, 4G is more difficult to hack.


Finding the best solution
Public Wi-Fi hotspots are more prone to infiltration compared to 4G. Enabling VPN when using a cellular or Wi-Fi connection is one of the most secure ways. This is followed by cellular-only and Wi-Fi-only networks.
Therefore to enable 360-degree protection, you should adopt a multi-layered approach that entails employing firewalls, anti-malware protection, VPNs, and even exercising caution while browsing the Web.

Virtual Private Network and its benefits

What is a VPN?
A Virtual Private Network (VPN) permits you to create a secure connection to another network over the Internet. VPNs can be used to enter region-restricted websites, protect your browsing activity from snooping eyes on public Wi-Fi, and more.
When you connect your computer or any another device like a smartphone or tablet to a VPN, the computer pretends as if it’s on the same local network as the VPN. All of your network traffic is transmitted over a secure connection to the VPN. Because your computer pretends as if it’s on the network, this permits you to securely access local network resources even when you’re on the different side of the planet. You’ll can also utilize the internet connection as if you were present at the VPN’s location, there are some benefits to it if you want access to geo-blocked sites or are using public Wi-Fi.  
When you surf the internet while connected to a VPN, your computer communicates with the website through encoded VPN connection. The VPN forwards the request for you and forwards the response from the website back through the secure connection. For example, if you’re using a location specific USA-based VPN to access Netflix, Netflix will perceive your connection as a USA user.

Uses of VPN
-          Access a Business Network while on the move: VPNs are regularly used by business travelers to get in touch with their business’ network, including all its local network resources while on the move.
-          Access your home network while on the move: You can also set up your own VPN to access your own network while you’re on the move.
-          Hide Your Browsing Activity from Your ISP and Local network: When you use a public Wi-Fi connection, your internet surfing activity on non-HTTPS websites can be viewed by everyone nearby, if they know how to look. You can hide all of this by connecting to a VPN.
-          Access Geo-blocked websites: If you’re an American and trying to connect to Netflix when outside of the country then you can use an American VPN to access the website.
-          Evade Internet censorship: Several Chinese people use VPNs to evade the great firewall of China and gain access to the entire internet.
-          Downloading files: You can use VPN to download files using torrent aggregators.

Leased Line Internet vs. VPN- Which is Preferable?

The Difference between a Leased Line and a VPN-
A leased line delivers a dedicated connection providing lots of bandwidth, but it typically provides no authentication or encryption.

A VPN (virtual private network) provides authentication and encryption over a connection that already exists, which might be a leased line or it may be an ADSL connection or it could also be a mobile network connection.
Your bandwidth requirements determine whether you require a leased line. Your security requirements determine whether you need a VPN.

Leased Line vs VPN - Which Is Cheaper?
VPNs are comparatively cheaper than leased lines. Industries regularly get leased lines for each of their chief offices and connect these together to form a wide-area-network (WAN). Several such businesses, but not all of them, run a VPN over the top of their leased lines to scramble the data flowing between their sites. In real-world terms this means they have a firewall at every office, confirming that internet traffic is scrambled before it leaves the premises of the company.

Several businesses let their staff work from home and to enable this they permit some members of their staff to join the office network remotely. Usually, this is achieved by installing an SSL VPN service or an IPsec VPN software on the employees' company laptops. Either of the VPN technology is selected, employees then join the corporate network through their usual Internet connections that will usually be 'consumer' broadband connections from Internet Service Providers.

Even though VPNs and leased lines are dissimilar, cost does play a role in some 'leased line vs VPN' decisions. For example, let's say you wanted to provide 20 employees with remote access to their work PCs from home. It would be expensive to pay for each employee to have a leased line. 

VPN vs Leased Line - Which Is More Secure?
VPN technology was solely created to provide cyber security and Leased were created with the intent to provide connectivity. Leased lines and VPNs solve very different problems. This doesn’t mean that leased lines are insecure, simply put their job is to deliver connectivity, not authentication or encryption.

Leased line and VPN services are provided by Tikona Infinet, an enterprise arm of Tikona Broadband. Businesses today have Internet supplied to their offices over fiber or cable. With infrastructure work on the escalation and numerous services digging the roads, frequent cable cuts are inevitable. This leads to Internet down-time disturbing businesses, that’s when leased line are optimal. Tikona also provides VPN services to businesses for a safer and secure internet connection.
