Implementation of Web Application Firewall

Web application firewall — Deployment and rule tuning.

Background

Beta Online Retail Pvt. Ltd. (anonymized) is a medium-sized e-commerce operator that depends on its web storefront.

Problem

Recurring SQL injection and cross-site scripting attacks interrupted service and put customer data at risk.

What I implemented

ModSecurity on the existing web servers
Rule sets aimed at SQL injection and XSS
Monitoring for new attack patterns and false positives
Integration with the company’s existing security tooling
Handover notes so the team could maintain and update rules

Outcome

Related web-attack incidents decreased after deployment, and the storefront stayed available. A WAF reduces exposure; it does not restore trust by slogan or prevent every future breach.
