Traditional algorithms run Packet-Filtering algorithms, Proxy algorithms, and Stateful/Stateful Inspection algorithms. WAF includes algorithms like Heuristics algorithms, Anomaly Detection algorithms, and Signature-based algorithms.Web application firewall typically safeguards Layer 7 of the OSI model, whereas firewall focus on layer 3 and layer 4.WAF firewalls focus on threats targeted at HTTP/HTTPS servers and apps. Standard firewalls are meant to allow or deny access to networks.A firewall is placed on the border of a network, functioning as a fence between known and unknown threats. The primary difference between WAF firewall and firewall is that WAF sits before the servers and apps, providing defense against threats that target servers.Traditional Firewall, on the other hand, offers protection against network threats.īoth standard firewalls and web application firewalls not only differ in the kind of protection they extend but also in total function. WAF firewall protects web applications against malicious attacks and vulnerabilities. The first measure may not be adequate by itself and does need to be strengthened with the second measure. As mentioned earlier, is to have strong web app security strategies and measures in place along with a custom-designed web app firewall.They must be developed on the right frameworks that have a good security track record so that they are more resistant to attacks.Web applications can be protected against vulnerabilities, cyber-risks, and attacks in two important ways. The most common attacks faced by web applications are SQL injection, cross-site scripting (XSS), CSRF, and DDoS attacks.Īccordingly, there is a strong need for web app security measures and strategies to combat these attacks, and a Web Application Firewall ( WAF) has come to occupy an indispensable place in such strategies. Websites, web applications, and servers, which are critical parts of the businesses of today, are high up on the hit list of cyber-attackers who find new and ingenious ways to orchestrate attacks. It is not just businesses who have benefitted from these advancements, even cybercriminals and crime syndicates have leveraged these to make financial and other gains in the process. In a span of a few years, we are experiencing rapid technological advancements that are revolutionizing the way the world functions.
