Today the Internet has become one of the indispensable forces of human life, and the pandemic has accelerated this growth by many folds by occupying the rightful place at the heart of our lives. The average person now connects to the vast expanse of the Internet at least a few times a day, drawn inexorably to its infinite possibilities.
Yet, a constant concern about cyber-attack threats lies within this intricate web of private, public, and hybrid networks where countless systems, electronic marvels, and AI devices converge. To shield ourselves and our digital infrastructure from these malevolent forces, we must harness the power of data security. The Firewall is one of the major components that help us as stalwart guardians.
What is Firewall?
A firewall is a security device that monitors incoming and outgoing traffic from a specific network and also filters data packets depending upon a set of rules configured as per the organization to prevent attacks. From the early days of the internet, we have been using different types of firewalls, which started with firewalls deployed on the host and gradually developed as exclusive devices which work for the whole network. To protect networks in an era where services are moving to the cloud Firewall as a Service comes into sight.
What is Firewall as a Service (FWaaS)?
FWaaS is a cloud-based firewall service that provides us with next-generation firewall features like segmentations, Intrusion Prevention Systems, VPN, sandboxing, malware protection, antispyware, and many others. In this, the organization does not require to obtain a hardware device and deploy it in any specific location. Organizations can deploy centralized firewall services for different locations of offices to secure their network. A third-party vendor helps us to maintain these firewalls. Due to Infrastructure-as-a-service, software-as-a-service, and other as-a-services, we have a big network created on the cloud, which is private, hybrid, or public. In addition to that, there is an increase in AI devices like thermal temperature checking and face recognition devices for authentication. Also, cloud storage devices create and upload bulk data on the cloud, which need to protect. FWaaS helps us to achieve this in a more effective way.
How FWaaS works?
FWaaS is a service that works between an organization’s network and the internet, which can be deployed in different ways.
Firewall desires to create a safe, private network for users, even though users should be able to connect to public services and another network with less interruption. In a firewall, you will get protection at different OSI layers. A firewall not only does packet filtering depending on the rule but also prevents the network from threats like spoofing, malware, virus, and phishing. Provide service which will protect the network from Flood attacks like DOS/DDOS attacks. Terminate Unauthorized access. As shown in the figure below, FWaaS works as a shield for components like DNS, load balancers, Remote Devices, etc.
How Happiest Minds is helping customers using FWaaS?
Happiest Minds are working with numerous global clients and giving them effective services, which include providing support to client in planning and deployment of network infrastructure where security of network is also involved and, we are working for migration of network and security services. The following is one of the case studies where we used a firewall as a service for the client and got amazing results.
We are working with an award-winning, non-profit, integrated health system. The client has multiple offices across the globe, and, during the pandemic, they acquired new land, where they were planning to set up healthcare centers. Unlike any health care center, they are supposed to collect immense personal and medical data of enrolled patients. In old office premises, they had a physical firewall for network security. For new centers, we wanted to provide them with a solution that would be best for them.
Here we proposed they use a firewall as a service for network security. The motive to use FWaaS instead of Next Generation Firewall is as below:
How Client network security look with physical firewall:
After using FWaaS:
Due to this this structure worked very well for them.
As seen above in the case study, Firewall as a Service has the upper hand in network security structure.
Advantages of FWaaS:
Challenges of FWaaS:
The usage of internet service and network infrastructure is changing rapidly, and so are types of firewalls and their structure. Firewall as a Service (FWaaS) is a centralized solution that works on cloud service terminology. It is a flexible solution that helps you to choose what is best for your network and update it according to your need. It will reduce your burden to manage local/physical appliances. The third-party vendor is always there to fulfill your requirement in an effective manner. Considering an advantage provided by FWaaS and its marketability, it is resulting in growth in the usage of FWaaS.
