[ PURPOSE & VALUE ]

What does Web Attack + WAF do?

Websites and API services are the most exposed doors businesses open to the outside world. Attackers constantly run automated scanners looking for SQL Injection, Cross-Site Scripting (XSS), Local/Remote File Inclusion (LFI/RFI), and remote code execution (RCE) flaws in your web applications. NextPcap's WAF module analyzes your web servers' access logs in depth. While ordinary WAF systems raise an alert for every request, NextPcap performs smart analysis: if the malicious request an attacker tried was blocked by your web server (e.g., returned HTTP 403 or 404), it's logged merely as a scan attempt. But if the request succeeded and the server returned HTTP 200 OK (e.g., an uploaded webshell fired successfully), it's instantly tagged as a Critical Breach, an urgent email is sent to the administrator, and the IP is blocked.

[ FEATURES ]

What Web Attack + WAF delivers

HTTP Response-Aware Alert Filtering

An innovative status-code filtering approach that keeps security teams from drowning in false-positive alerts.

Behavioral Anomaly Scoring

Protects against previously unseen (zero-day) bypass payload variations by computing an anomaly score, not just matching known signatures.

Historical Payload Forensics

Stores every blocked request's full HTTP headers, User-Agent, and raw payload in the database for forensic analysis.

[ HOW IT WORKS ]

Live in three steps

Listen

Changes in the web server's log directory are streamed to the NextPcap portal in real time via SSH or the PHP agent.

Analyze

The request path, parameters, and HTTP status code in each log line pass through our regex signature engine.

Block

If the response was successful (2xx or 3xx) and the payload was malicious, the IP is blocked within seconds and an alert chain is created.

[ FAQ ]

Frequently asked questions about Web Attack + WAF

How does NextPcap WAF reduce false-positive alerts?

Through HTTP response-aware filtering: blocked attempts (403/404) are logged as low-priority, while genuinely successful breaches (2xx/3xx) are flagged as critical alerts.

Does the WAF module catch zero-day attacks?

Yes — its behavioral anomaly score also detects new payload variations outside of known signatures.
