Intelligent and Trending Approach of Web Application Firewall (WAF) in 2020

Wednesday, 23 September 2020 / Published in Web Application Firewall

Intelligent and Trending Approach of Web Application Firewall (WAF) in 2020

In this article today we would be sharing the information and details that is related to the trending and most intelligent approach of Web Application Firewall and network firewall.

Introduction to Web Application Firewall (WAF)

A WAF – Web Application Firewall is the web form that is undertaken to filter, block inbound and outbound web application HTTP traffic. WAFs hold an extensive focus on the traffic that hits on the application and with this it has the ability to provide in-depth data flow analysis.

WAF is safe and secure method as well as approach that protects web application from all types attacks such as cross-site scripting, file inclusion, and SQL injection, among others. The attack migration method that is a usually the part of a suite of tools that in all assist in creating a holistic defense against the range of attack vectors.

Now moving further, let us understand one thing and that is the need to know the nature of the frequent network attacks. Some of them indeed successfully performed well and that is when the attackers managed to find a vulnerability in the code and this in return is been use to make the malware look like a part of the application traffic.

Taking it further, let us now have an understanding in knowing what Network firewall services is all about.

What’s Network Firewall?

To monitor web traffic across the network and also to control its access, the method that is undertaken is Network Firewall. It also shares the authorities for the outbound sessions. Also, it is a fact that this process of work is only located with the attribute of network layer and that is in the OSI layer. This comes up with an low access control limits.

The ordinary network firewalls do not have the mechanism to detect or prevent these threats. It only gives an access to very limited security from malware, attacks, and other unauthorized activities.

How Does Web Application Firewall Security Work?

Web Applications Firewalls basically are designed to make sure that the placement is done properly on the application layer. This process acts as a two-way gatekeeper. The best benefit Web Application Firewall is  that, they have capability to continuously adjust to the application behaviour changes.

You might think that we can have a standard Network Firewall for blocking the traffic. But you need to know the difference between these two.

Difference Between Web Application Firewall and Network Firewall

Below is the difference between these two services. Let us all have a quick update on it.

  • Web Application Firewall:
    A WAF is a network security firewall solution that protects web applications from HTTP/S and web application-based security vulnerabilities.
  • Network Firewall:
    The network firewall is a device that controls access to secured LAN Network to protect it from unauthorized access, the firewall acts as a filter that blocks incoming non-legitimate traffic from entering the LAN network and cause attacks.

Moving further, in the said post, let us also have an understanding on some of the types of WAF’s that assist in overall configuration of the service. The list for the same is as mentioned below.

  • Network-based WAF
    When talking about network based WAF, the normal process here is generally hardware based. Since, the installation work is done locally, they assist in reducing latency. Also, one thing that needs to be known is that WAFs are termed to be one of the most expensive options and this also requires the storage and maintenance of physical equipment.
  • Host-based WAF
    A Host-based WAF may be fully integrated into an application’s software. This solution of work is indeed less expensive as that compared to network-based WAF and offers more customizability. The downside of host-based WAF is the consumption of local servers.
  • Cloud-based WAF
    Cloud-based WAF provides an affordable option that is very easy to implement. They usually offer a turnkey installation that is simple as a change in DNS to redirect traffic. Cloud-based WAF’s can also provide a consistently updated solution to protect against the newest threats without any additional work on cost on the user’s end. The drawback of a cloud-based WAF is that users hand over the responsibility to a third-party.

Taking it further, this is the service that also has some of the best features too that play an integral part of the service and the listing for the same is as shared below.

  • Protection Against the OWASP Top 10
  • Protection against known and unknown attacks
  • PCI DSS Compliance
  • High performance without Negative Impact.
  • Centralized Management

Moving further, when undertaking the service most important thing that needs to be taken care of is the process how it gets streamlined and how it is been built for the security needs of the clients and their data along with server.

Cloud Stack Group is the leading and one stop company based in India that provides 100% accurate and precise Web Application Services with the process of adherence of all  the necessary steps and work that is required in the service.

The company has served numbers of projects on WAF that turns out to be the best and because of the dedication towards the work, they have become one of the most trusted as well as recommended AWS service provider who is with and for the clients 24*7 and all 365 days a year.

Having said this, to know more about the service or to understand how it works, the best method is you can connect with them over the phone or can send an email to them. The team will share with you the details that is best suitable for you and your company.
