Web Application Firewall. Enhancing web security in the digital age.pdf
- 1. WEB APPLICATION FIREWALL: Enhancing Web Security in the Digital Age
- 2. INTRODUCTION Web applications are integral to modern business functions, serving as platforms for operations, communication, and commerce. However, this reliance on web technologies exposes these applications to a plethora of cyber threats. Web Application Firewalls (WAFs) have become indispensable in mitigating these risks by providing a protective barrier between web applications and potential attackers.
- 3. Challenge-Response Mechanisms Features:- WAFs offer a range of features and capabilities aimed at detecting and mitigating common web-based attacks, including: Rule-Based Filtering Anomaly Detection Protection Against DDoS Attacks
- 4. Benefits of Advanced WAF:- 01 Enhanced threat detection and prevention 02 Real-time monitoring and incident response capabilities 03 Machine learning and AI-powered security intelligence A WAF or web application firewall helps protect web applications by filtering and monitoring HTTP traffic between a web application and the Internet.
- 5. Key Challenges with Traditional WAF:- Difficulty in managing false positives Inability to detect advanced threats Limited Rule-based protections Lack of scalability and performance issues
- 6. HOW WAF WORKS? Traffic Inspection- Logging And reporting- A Web Application Firewall(WAF) works as a barrier between your web application and the internet, protecting it from various types of cyber threats and attacks. When a request is made to your web application, the WAF intercepts it before it reaches your application server. It inspects both the request (incoming traffic) and the response (outgoing traffic). WAFs typically maintain logs of all incoming requests, including those that are blocked, allowed, or flagged for further investigation. This logging provides valuable insights into the nature and frequency of attacks, helping administrators fine-tune security policies and respond to incidents effectively.
- 7. WAF WORKS:- Rate limiting and access control- Rule-Based Filtering- A Web Application Firewall (WAF) works as a barrier between your web application and the internet, protecting it from various types of cyber threats and attacks. WAFs can also enforce rate limiting policies to prevent abuse or excessive requests from reaching your application servers. They can control access based on factors like IP address, geolocation, user agent, and more, helping to mitigate DDoS attacks and brute force attempts. WAFs use pre-defined rulesets or custom rules configured by administrators to analyze incoming traffic for signs of malicious activity or suspicious patterns. These rules can cover a wide range of attack vectors, including SQL injection, cross-site scripting (XSS), and other common web application vulnerabilities.
