Web Application Firewall (WAF) and DDoS high-defense packages serve different purposes in cybersecurity. A WAF is designed to protect web applications from various attacks, such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). It analyzes HTTP/HTTPS traffic to and from a web application to filter out malicious requests.
On the other hand, DDoS high-defense packages are intended to mitigate Distributed Denial of Service (DDoS) attacks, which aim to overwhelm a website or service with a massive volume of traffic, rendering it inaccessible.
While WAFs can help mitigate some forms of DDoS attacks, especially those targeting web applications, they are not a substitute for dedicated DDoS protection services. WAFs typically have limited capacity to handle large-scale DDoS attacks, which is where DDoS high-defense packages come into play.
For example, if a website experiences a DDoS attack that exceeds the capacity of its WAF, the WAF may not be able to effectively filter out the malicious traffic, leading to service disruption. In such cases, a dedicated DDoS high-defense package would be necessary to absorb and mitigate the attack.
To effectively protect against both web application attacks and DDoS attacks, organizations often deploy a combination of WAF and DDoS protection services. Tencent Cloud offers a comprehensive suite of security services, including Web Application Firewall (Tencent Cloud Web Application Firewall) and Anti-DDoS Pro (Tencent Cloud Anti-DDoS Pro), which can be used together to provide layered protection against a wide range of cyber threats.
