  1. SECURE YOUR WEB APPLICATION WITH AN OPEN SOURCE WAF

  2. WEB APPLICATION FIREWALL A Web Application Firewall (WAF) is a security solution designed to protect web applications by filtering and monitoring HTTP and HTTPS traffic between the application and the internet. WAFs operate at the application layer (Layer 7 of the OSI model) and are specifically designed to detect and prevent attacks that target web applications. WAFs work by analyzing incoming traffic and blocking or allowing requests based on predefined security rules. These rules are often based on known attack patterns and can be customized to meet the specific needs of an organization. By acting as a barrier between the web application and potential attackers, a WAF helps prevent unauthorized access, data breaches, and other forms of cyberattacks.

  3. Vision & Mission VISION MISSION To be the leading Open Source Web Application Firewall (WAF) solution that empowers organizations worldwide to protect their digital assets, ensuring robust, scalable, and transparent security for all web applications, while fostering collaboration and innovation in the cybersecurity community. Our mission is to provide a high-performance, cost- effective, and customizable Open Source WAF that delivers top-tier web application protection against modern cyber threats. We strive to build a global community where developers and security professionals can contribute, enhance, and adopt cutting-edge security measures that ensure the safety and integrity of online applications for all.

  4. WHY CHOOSE OPEN SOURCE WAF? 1 2 3 4 Customization Flexibility Community Support Cost-Effectiveness Open-source WAFs benefit from a community of developers and users who contribute to the project, provide support, and share best practices. This community-driven approach leads to continuous improvement and innovation. Open-source WAFs can be deployed in various environments, including on- premises, in the cloud, or in hybrid setups. This flexibility allows organizations to integrate the WAF seamlessly into their existing infrastructure. Open-source WAFs are generally more affordable than their commercial counterparts. This makes them an attractive option for small to medium-sized businesses (SMBs) and startups with limited security budgets. Open-source WAFs offer a high degree of customization. Since the source code is publicly available, organizations can tailor the WAF to their specific needs, adding or modifying features as required.

  5. BENEFITS OF USING OPEN SOURCE WAF REAL-TIME MONITORING AND LOGGING SCALABILITY ENHANCED SECURITY Open-source WAFs provide robust protection against a wide range of web application threats. By filtering and monitoring HTTP/HTTPS traffic, they can detect and block common attack vectors such as SQL injection, XSS, CSRF, and more. Open-source WAFs typically provide real-time monitoring and logging capabilities, allowing security teams to track and analyze traffic patterns, identify potential threats, and respond to incidents quickly. Many open-source WAFs are designed to scale with the growth of an organization. As web traffic increases, the WAF can be configured to handle larger volumes of data without compromising performance. This scalability ensures that web applications remain protected even as the business expands.

  6. Element Of Open Source WAF FEATURES Open Source Web Application Firewalls (WAFs) offer a cost- effective, customizable solution applications from common security vulnerabilities. for protecting web COST- EFFECTIVE CUSTOMIZABILITY Unlike proprietary WAFs, open-source options provide transparency, community-driven support, and flexibility in implementation, making them organizations with specific security needs. an ideal choice for Open-source Web Application Firewalls are security solutions developed and maintained by a community of developers, and they are typically available for free or at a lower cost than commercial WAFs. COMMUNITY SUPPORT COLLABORATIVE INNOVATION

  7. CHALLENGES OF OPEN SOURCE WAF While open-source WAFs offer numerous benefits, they are not without challenges. It’s important to consider these potential drawbacks when deciding whether to deploy an open-source WAF. COMPLEXITY OF SETUP AND CONFIGURATION COMMUNITY SUPPORT LIMITED VENDOR SUPPORT MAINTENANCE AND UPDATES PERFORMANCE OVERHEADS

  8. POPULAR OPEN SOURCE WAF SOLUTIONS OWASP CORE RULE SET (CRS) MODSECURITY IRONBEE NAXSI

  9. MODSECURITY& OWASP CORE RULE SET ModSecurity is one of the most well-known open-source WAFs. Originally developed ModSecurity has since expanded to support other web servers, including Nginx and IIS. It offers comprehensive protection against various web application threats and provides a powerful rules engine for creating custom security policies. ModSecurity’s flexibility, coupled with its active community support, makes it a popular choice for organizations of all sizes. as an Apache module, The OWASP Core Rule Set (CRS) is a set of generic attack detection rules designed to protect web applications from a wide range of threats. While not a WAF itself, CRS can be used in conjunction with ModSecurity or other WAFs to enhance their capabilities. CRS is maintained by the Open Web Application Security Project (OWASP), a respected organization in the cybersecurity community.

  10. NAXSI & IRONBEE NAXSI (Nginx Anti XSS & SQL Injection) is an open-source WAF designed specifically for Nginx web servers. It is lightweight, fast, and focuses on preventing XSS and SQL injection attacks. NAXSI uses a positive security model, which means it blocks only malicious requests that do not match predefined rules, reducing the likelihood of false positives. IronBee is a relatively newer open-source WAF framework designed to be highly flexible and extensible. It provides a modular architecture that allows organizations to customize the WAF according to their needs. IronBee is designed to work with a variety of web servers and can be integrated into existing security infrastructures.

  11. CONCLUSION Securing your web applications is a critical component of any cybersecurity strategy, and an open-source Web Application Firewall (WAF) can be an effective and cost-efficient solution. Open-source WAFs offer flexibility, customization, and community- driven support, making them a viable option for organizations of all sizes. While there are challenges associated with deploying and maintaining an open-source WAF, the benefits often outweigh the drawbacks when implemented correctly.Whether you choose ModSecurity, NAXSI, or another open- source WAF, the key is to stay vigilant, proactive, and committed to maintaining a strong security posture in today’s ever-evolving threat landscape.

  12. THANK YOU! By understanding the pros and cons of open- source WAFs, selecting the right solution, and following best practices for deployment, you can significantly enhance the security of your web applications and protect your organization from cyber threats. +91 120 4545911 www.haltdos.com B-21, B Block, Sector 59, Noida, Uttar Pradesh 201309
