Web application firewalls help protect web applications from malicious attacks and unwanted internet traffic, including bots, injection and application-layer denial of service (DoS). The WAF will help you establish and manage rules for avoiding internet threats, including IP addresses, HTTP headers, HTTP body, URI strings, cross-site scripting (XSS), SQL injection, and other OWASP-defined vulnerabilities. Web application firewall are deployed to protect web-facing applications and collect access logs for compliance, and analytics.
There are a number of components of the WAF, notably:
Some of the key capabilities and features of WAFs include:
A cloud based WAF must support multiple web application hosting environments including on-premises, cloud, hybrid, and multi-cloud. Meaning, a WAF can protect a network edge from malicious traffic regardless of how many infrastructure providers are used. The right cloud based WAF will provide an independent platform for securing all internet facing applications and APIs, no matter where they reside.
The best cloud based WAFs are managed 24/7 by a team of experienced internet security experts who monitor an environment and recommend proven threat mitigation steps when issues arise. The benefits of a managed WAF service include significant risk reduction. The burden of management is also reduced due to WAF configuration, monitoring, tuning, and incident response as the responsibility of the cloud provider. Continuous monitoring protects organizations from unplanned downtime and the resulting damage to a brands reputation. Additionally, managed services enable more time to be focused on core business tasks and improving the bottom line. Cloud-based WAFs provide the highest level of web application security without a major upfront investment in resources or ongoing costs related to maintenance, hardware replacement, and software upgrades. Cloud-based WAFs offer ease of deployment and predictable subscription pricing, which makes budget planning easier.
The Web Application Firewall (WAF) filters out malicious requests to a web application or API. It also provides more visibility as to where the traffic is coming from—and Layer 7 distributed denial of service (DDos) attacks are mitigated, to help gain application availability, and better enforce compliance mandates.
The bot management solution uses detection techniques such as IP rate limiting, CAPTCHA, device fingerprinting, and human interaction challenges to identify and block bad and/ or suspicious bot activity from scraping your website for competitive data. At the same time, the WAF can allow legitimate bot traffic from Google, Facebook, and others to continue to access your web applications as intended. WAF employs an intelligent Domain Name System (DNS) using a data-driven algorithm that determines the best global point of presence (POP) to serve a given user in real time. As a result, users are routed around global network issues and potential latency while offering the best possible uptime and service levels.
