Do you know what Web Application Firewall is and what this security feature is for? Let's talk about it in today's blog!<\/span><\/pre>\n
With the growing dependence on web applications in sectors such as health, retail, finance and technology, the attack surface for digital criminals has increased dramatically. In added time, many of these applications handle sensitive information, such as personal or financial data, which are valuable targets.<\/span><\/p>\n
A WAF is therefore one of the first steps towards strengthening application security, mitigating risks and ensuring compliance with data protection regulations such as LGPD and GDPR.<\/span><\/p>\n
In this sense, the more we talk about cybersecurity, the more it becomes understandable how important this subject is today. From the perspective set out above, we understand that protecting web applications has long since ceased to be a differentiator and has become a critical necessity.<\/span><\/p>\n
After all, attacks such as SQL injection, cross-site scripting (XSS) and DDoS pose risks not only to data, but also to reputation and business continuity. This is why the Web Application Firewall (WAF) has established itself as an indispensable solution.\u00a0<\/span><\/p>\n
It acts as a layer of protection that filters and monitors traffic between users and applications, identifying and mitigating threats before they cause damage.<\/span><\/p>\n
Throughout this content, you will be able to learn in depth what WAF is and its components, how it is applied in practice, as well as its importance. Enjoy your reading!<\/span><\/p>\n
What is a WAF (Web Application Firewall)?<\/b><\/h1>\n
A Web Application Firewall (WAF) is a cybersecurity tool designed to protect web applications from specific threats that exploit vulnerabilities<\/a> in code, configurations or data. It acts as a barrier between the user and the application server, monitoring, analyzing and filtering HTTP\/HTTPS traffic.<\/span><\/p>\n
Unlike traditional firewalls, which focus on protecting networks and endpoints by blocking ports, malicious packets or unauthorized traffic, WAF works on a more granular level.\u00a0<\/span><\/p>\n
Its main objective is to protect web applications against attacks such as:<\/strong><\/p>\n
