Secure Connectivity of Public Cloud Networks

Despite every effort, security remains one of the major concerns for businesses planning their move to the cloud. It is one of the reasons businesses opt for a private cloud. However, the private cloud comes with its own set of issues including a higher cost.

Public cloud is the most budget friendly option. The global public cloud service market has almost hit $200 billion. Businesses are likely to spend 80% of their IT budget on cloud solutions. A huge chunk of it will be spent on cloud security. Fortunately, there is a sure-shot way to make it just as secure as any private cloud – through a Virtual Private Network or a VPN.

VPN is not something unheard of. Most users are aware of its many uses that include access to restricted websites or protecting your IP from spies and attackers. This same VPN can be used to secure your public cloud networks and make them less vulnerable.

How Does a VPN Work?

Before we dive into the “How”, let’s talk about the “What”.

So what is a VPN? A VPN can be simply defined as a network built around your actual network. It offers a secure access point to any server or site. Once connected, it creates a secure communication pathway between the user and the information they want to access no matter where it is located.

So, how does a VPN really work? By creating a proxy network, a VPN gives you a more private path to access any information on the internet. A cloud VPN can establish a similar secure and private connection with the cloud. A VPN adds a solid layer of encryption. So, even if you are visiting a site that doesn’t use encryption, you will have your own line of defense.

This inherent ability of a VPN to secure both the data and the user makes it a natural choice for businesses on public cloud networks. It is especially helpful for organizations where employees access the public cloud through various personal devices.

How to Secure Your Public Cloud Networks through a VPN

VPNs can provide an effective solution to secure the delivery of data to and from the cloud networks. You can use a VPN to create secure and private sub networks. The VPN will use standard encryption techniques to make sure the transmission is as secure as possible.

Other security protocols such as IPSec can be used to improve the implementation and performance of a VPN. VPN and these protocols work together to deliver a more robust standard of security over a network. It also improves data confidentiality and access control across your network. The VPN secures the network infrastructure while the IPsec improves the wireless transmission of data over that network.

What Can Be Achieved through VPN for Public Cloud Networks

Integration of a VPN with a firewall can offer a lot of benefits. It can reduce the throughput by limiting the number of bits transmitted per second. It will block unauthorized access and therefore the number of access attempts to the server will also be limited.

While many say that a VPN can increase the delay, it is quite the opposite. The delay on a network with a VPN is generally smaller than on a network without a VPN.

VPN technology is an appropriate way to secure cloud computing. It decreases the traffic in the system to achieve the desired level of security. The security provided in VPN technology with the firewall allows only specific access to the server. By reducing the number of access, a VPN firewall can deliver you the anticipated security level on a public cloud network.

The Importance of Securing Your Cloud Network

It is true that private cloud hosting companies and cloud vendors are all playing their role in improving security in the cloud. However, it seems like the attackers are getting equally advanced. The public cloud is now trusted by around a quarter of organizations across the US. The implications of these numbers on the number of security breaches is quite clear.

There were numerous data breaches in the year 2017 and 2018. Just the healthcare sector alone witnessed a 420% increase in attacks. Those attacks exposed nearly 99 billion private records, compromising the privacy of billions of patients.

What’s worse is that these breaches aren’t inexpensive. The average cost of a network breach will soon hit $150 billion.  The result can be fatal for any organization. We have seen numerous cases of companies closing and shutting down after a breach.

This is why network security is so crucial for any business, especially when you are moving to a public cloud. No matter what your cloud vendor or service provider says about their security, a VPN is your best bet.

Conclusion

Security is never 100 percent guaranteed, but there are ways to make your network more resilient and robust. There may be other ways to secure your cloud network, but a VPN stands as an undisputed winner.
