A Web Application Firewall (WAF) serves as a vital security control that shields websites and web applications from cyberattacks. Think of it as a discerning doorman at an exclusive club, determining who gains access and who is denied.
Its role involves analyzing the traffic between the internet and the web application, effectively blocking any suspicious activities. Unlike traditional firewalls that focus on network protection, WAFs are specifically designed to combat web-based attacks.
To complement WAFs, a newer technology called Runtime Application Self-Protection (RASP) detects and halts assaults in real-time, right within the application itself.
Understanding Web Application Firewall (WAF)
A web application firewall, commonly known as WAF, acts as a shield for web applications by meticulously filtering and monitoring HTTP traffic between the web application and the Internet.
It provides protection against various types of attacks, including cross-site forgery, cross-site scripting (XSS), file inclusion, and SQL injection.
It operates as a defense mechanism at protocol layer 7 within the OSI model and is typically part of a comprehensive suite of tools that collectively offer robust defense against multiple attack vectors.
The Role and Function of a Web Application Firewall (WAF)
A WAF safeguards web applications by effectively filtering, monitoring, and blocking any malicious HTTP/S traffic destined for the application. By adhering to predefined policies, it distinguishes between secure and malicious traffic, preventing unauthorized data from leaving the application.
Similar to how a proxy server safeguards a client’s identity, a WAF acts as an intermediary to protect the web application server from potentially malicious clients, working in reverse proxy mode.
WAFs can be implemented as software, hardware appliances, or services, allowing flexibility to tailor policies based on the specific requirements of your web application or application portfolio.
While regular policy updates are often necessary to address new vulnerabilities, advancements in machine learning enable some WAFs to update themselves autonomously. This automated approach becomes increasingly crucial as the threat landscape grows in complexity and uncertainty.
What sets a WAF apart from a firewall?
A web application firewall (WAF) and a traditional firewall have distinct differences in terms of their scope and functionality. Let’s explore the contrasting features of these security measures:
WAF: Safeguarding the Application Layer A WAF is specifically designed to protect the application layer by analyzing each HTTP/S request at that layer. It operates with awareness of the user, session, and application, including the web applications and services they interact with.
Think of a WAF as the intermediary between the user and the application, scrutinizing all communications before they reach either party. WAFs ensure that only authorized actions, based on security policies, are allowed.
They serve as the initial line of defense for applications, especially in addressing the OWASP Top 10, which outlines common vulnerabilities in applications.
Top 10 Application Vulnerabilities:
- Injection Attacks
- Broken Authentication
- Sensitive Data Exposure
- XML External Entities (XXE)
- Broken Access Control
- Security Misconfigurations
- Cross-Site Scripting (XSS)
- Insecure Deserialization
- Using Components with Known Vulnerabilities
- Insufficient Logging and Monitoring
Web Attacks vs. Unauthorized Access
WAF solutions protect organizations from web-based attacks targeted at applications. Without a WAF, vulnerabilities in web applications could be exploited by attackers to breach the network. WAF security solutions shield enterprises from common web attacks, including:
- DDoS (Distributed Denial of Service): Attempts to disrupt a network or server by overwhelming it with excessive internet traffic, depleting resources. Defending against DDoS attacks can be challenging as the traffic may not always appear malicious.
- SQL Injection: Allows hackers to execute malicious SQL statements to manipulate the database server underlying a web application. This can bypass webpage authentication, retrieve database contents, and modify or delete records. SQL injection has been ranked as the top threat to web application security.
- Cross-Site Scripting (XSS): A web security flaw enabling attackers to compromise user interactions with web applications, impersonating legitimate users to gain unauthorized access to data and resources.
Network Traffic vs. Application Traffic
Traditional network firewalls focus on limiting or preventing unauthorized network access. Firewall policies define permitted network traffic, blocking any attempts outside of those defined rules. This helps prevent unauthorized network traffic and attacks from users or devices in less secure zones.
In contrast, a WAF specifically targets application traffic. It safeguards HTTP and HTTPS traffic and protects applications in internet-accessible network zones. This shields businesses from threats like cross-site scripting (XSS), distributed denial of service (DDoS), and SQL injection attacks.
Safeguarding at Layer 7 instead of Layers 3 and 4
In the realm of firewall protection, a fundamental technical distinction arises from the security layer on which these firewalls operate.
The Open Systems Interconnection (OSI) model serves as a framework that identifies and standardizes communication functions across telecommunication and computing systems.
Web Application Firewalls (WAFs) offer protection against intrusions at Layer 7 of the OSI model, known as the application layer. This encompasses defending against various threats such as cookie manipulation, SQL injection, URL attacks, and assaults targeting application-specific technologies like Ajax, ActiveX, and JavaScript.
WAFs also focus on safeguarding the web application protocols, namely HTTP and HTTPS, which establish connections between web browsers and web servers.
For instance, in a Layer 7 DDoS attack, a flood of traffic is directed at the server layer, where web pages are generated and delivered in response to HTTP requests.
To mitigate such attacks, a WAF acts as a reverse proxy, shielding the targeted server from malicious traffic and employing filtering mechanisms to identify DDoS tools.
In contrast, network firewalls rely on Layers 3 and 4 of the OSI model to provide protection for data transfer and network traffic. This includes defending against attacks targeting protocols like DNS, FTP, SMTP, SSH, and Telnet.
Noteworthy providers such as Amazon Web Services (AWS) and Cloudflare offer Web Application Firewall (WAF) services to enhance security measures.
