The difference between waf firewall and web firewall: 1. The function of web firewall is to control HTTP or HTTPS access, carry out precise control of traffic in multiple dimensions, and support specified IP or network segments; 2. The function of Waf firewall It is to analyze the GET or POST request sent by the client using the HTTP/HTTPS protocol.
The difference between waf firewall and web firewall:
Function of Web firewall:
1. Web application attack protection, general Web attack protection, virtual patches for 0day vulnerabilities, website invisibility; protection against common OWASP threats, virtual patches for high-risk Web 0day vulnerabilities, automatic defense to ensure server security, and rapid protection of 0day vulnerabilities ; For high-risk Web 0day vulnerabilities, the professional security team provides virtual patches within 24 hours and automatically defends to ensure server security.
2. CC attack, filter malicious Bot traffic, ensure normal server performance, and low manslaughter protection algorithm. It is no longer a direct and crude ban on IPs that access too frequently. Instead, abnormal behaviors are judged based on distribution characteristics such as URL requests and response codes, and malicious characteristic attacks are 100% intercepted. Configure access control for common header fields in requests, such as IP, URL, User-Agent, Referer, and malicious characteristics appearing in parameters, and provide the ability to block massive malicious IP blacklists and malicious crawler libraries.
3. HTTP/HTTPS access control, precise control of traffic in multiple dimensions, supporting the blocking or whitening of specified IPs or network segments, as well as malicious IPs; malicious crawler protection, blocking libcurl, python scripts and other structures malicious access. It can be said that only cloud vendors provide such servers. A hardware web firewall costs thousands or millions, and it also comes with services.
Waf firewall is a software form, which can facilitate many webmasters and server operation and maintenance personnel through software algorithms.

Functions of Waf firewall:
1 , Protection function: Analyze GET/POST requests sent by the client using the HTTP/HTTPS protocol, and apply access rules to filter malicious access traffic. Use the web protection function directly to resist common web protection functions. We combined Web attack characteristics, analyzed request headers and request bodies, wrote precise filtering algorithms, and encapsulated these complex filtering algorithms with various protection functions for easy and direct use.
2. Attack protection: Helps you protect against common web attacks such as SQL injection and XSS cross-site attacks.
3. CC attack protection: Helps you protect against CC attacks against page requests.
4. Protection engine: performs semantic analysis on requests, detects disguised or hidden malicious requests, and helps you protect against malicious attacks initiated through attack confusion, variants, etc.
5. Malicious IP punishment: Helps you automatically ban client IPs that have carried out multiple web attacks in a short period of time.
6. Geographical IP blocking: Helps you block access requests from IPs from designated domestic provinces or overseas regions with one click.
These functions are the special skills of Waf. Speaking of which, it is recommended to use a Linux server. It is troublesome to build a Waf firewall on Linux, and you need to know certain technologies. Nowadays, many Linux panels have the function of building a WAF firewall. Many panels charge 20 yuan per month for this function. Sailfish Cloud Ladder is free to use and has many functions. Powerful, blocks most attacks.
