Web Application Firewall

What Is a Web Application Firewall (WAF)? Full Overview

With the increasingly interconnected digital environment, UAE businesses are constantly faced with the challenge of securing their web applications against cyberattacks. With more activities being shifted to the web, having a secure online presence has never been more paramount. It is in this context that a Web Application Firewall (WAF) comes into play with its enhanced ability to defend against various kinds of cyberattacks.

In this article, we will discuss what a WAF is, how it functions, why it is important, and why UAE businesses must invest in WAF security services. We will also discuss how NetForChoice, one of the top WAF service providers UAE, can assist you in securing your business from cyber threats using advanced, cloud-based WAF solutions.

What is a Web Application Firewall (WAF)?

A Web Application Firewall (WAF) is a security design that is used to defend web applications by filtering and inspecting HTTP/HTTPS traffic between a web application and the internet. It serves as a shield that blocks incoming traffic, stopping malicious data packets from entering your web applications and causing normal operations to be interrupted.

In contrast to the network-centric firewalls used in the past, WAFs are application-oriented, with protection at the application level (Layer 7 of the OSI model). A WAF is capable of identifying and preventing a broad array of cyber attacks, such as SQL injection attacks, cross-site scripting (XSS), and other web-based exploits that can take advantage of vulnerabilities in your application code.

Why is WAF Necessary for UAE Companies?

As businesses in the UAE quickly grow their online presence, web application risks grow exponentially. Cyber attackers are always coming up with new ways to exploit systems and steal confidential information. For companies that provide e-commerce, online banking, or any other customer service, a data breach can lead to hefty financial losses, a damaged reputation, and legal repercussions.

The following are some of the most important reasons why UAE businesses need a WAF:

1. Protection Against OWASP Top 10 Threats

Open Web Application Security Project (OWASP) Top 10 is the most essential web application security vulnerabilities. Many of  these risks, such as SQL injection and cross-site scripting, are the targets of enterprises’ online services. A WAF can minimize the risks through preventing malicious traffic from reaching your application.

2. Adherence to Local and International Regulations

For businesses operating in the UAE, regulatory compliance is critical. A WAF helps ensure that your web applications are compliant with regulatory standards, such as the UAE Cybersecurity Law, and global standards such as GDPR. With a WAF, businesses can make sure that they safeguard customer data and web application integrity.

3. Real-time threat detection and prevention

On-premises WAF dynamically monitors all inbound traffic, discovering and blocking attacks in real-time. In contrast to traditional network firewalls that can only find known threats, a WAF can block highly sophisticated attacks, such as zero-day vulnerabilities, that could otherwise evade traditional defenses.

4. Sensitive Customer Data Protection

For e-commerce sites, online banking websites, and any business that deals with sensitive customer information, a WAF is crucial to avoid data leakage. Using a WAF, you can protect personal data, credit card information, and other sensitive data from cybercriminals who are seeking to exploit vulnerabilities in your web applications.

How Does a WAF Work?

The Web Application Firewall operates by inspecting and filtering all in-or-out HTTP/HTTPS traffic to and from web applications. In the process, it analyzes traffic for suspicious activities and blocks suspicious requests. WAFs provide many security mechanisms based on models like allow listing, block listing, and hybrid security models to protect web applications.

Key Functions of a WAF:

• Traffic Inspection – A WAF monitors all incoming traffic and compares it to a set of security rules to determine if it’s safe or malicious.
• Threat Blocking – If a threat is detected, the WAF blocks the malicious request, preventing the attack from reaching the application.
• Log Management – WAFs log all traffic and potential threats, providing businesses with insights into attempted attacks and security breaches.

Types of WAF Deployment

There are several types of WAF deployments, each suited for different needs. Businesses in the UAE can choose from the following:

1. Network-based WAF

This kind of WAF is generally situated on-site as hardware. It is designed to minimize latency and provides faster processing times due to its positioning near the web application server. However, they require heavy hardware and maintenance investments.

2. Cloud-based WAF

Cloud-based WAFs are run by third-party suppliers and provide low-cost, low-maintenance security. With the scalability to grow with a business, these options are favored among UAE firms for fast deployment, low costs, and quick scalability.

3. Hybrid WAF

A hybrid WAF combines both network and cloud-based solutions, providing businesses with the flexibility and control of on-premise systems and the scalability of cloud-based solutions. This approach can be beneficial for large enterprises that require extensive customization and configuration.
