In the world of web security, reconnaissance is the first step for most attackers. Tools like Nmap, SQLmap, Nessus,and other automated scanners are often used to map your network, identify open ports, and detect vulnerabilities. Without proper protection, your website could be exposed before you even realize it.
Luckily, SafeLine WAF provides a robust and dynamic defense against these common scanning tools. This article will guide you on how SafeLine makes hackers’ scanners useless.
1. Why Scanners Are Dangerous
Hackers use scanners to collect critical information about your servers and applications:
- Port scans reveal open services that may have weak points.
- Service fingerprinting helps attackers identify software versions and known vulnerabilities.
- Web vulnerability scans can detect SQL injection points, XSS flaws, or exposed APIs.
Without mitigation, these scans give attackers a map to plan their attacks.
2. SafeLine’s Magic
SafeLine WAF leverages Chaitin Technology’s proprietary semantic analysis engine to detect network threats while supporting unlimited custom rules to further optimize detection.
To block common hacker scanners, you can simply set up custom rules in SafeLine—no coding required, everything can be configured directly through the SafeLine dashboard.
You can set up a deny rule like this:
