Overview
We built a centralized security monitoring and response system that unifies event logging, authentication tracking, IP and fraud-based blocking, and AI-assisted querying across a CRM platform and its connected WordPress/WooCommerce storefronts. We delivered a rule-based protection engine, a live React threat dashboard, and a fail-open WordPress connector so the business stays both protected and online.
Challenges
- Security signals were scattered across the CRM, WordPress, WooCommerce, and Nginx logs, leaving no single place to see what was actually happening across the business.
- Brute-force login attempts could hammer accounts unchecked, with no failure threshold to warn on suspicious activity or automatically lock out attackers.
- Common web attacks like SQL injection, cross-site scripting, and path traversal could slip through without pattern detection at the request layer.
- Malformed authentication cookies, session hijacking attempts, and quiet privilege escalations such as unexpected role changes or super-admin grants could go completely unnoticed.
- WooCommerce was exposed to fraudulent and high-risk orders — geography mismatches, disposable email domains, VPN/proxy use, card-testing patterns, and abnormal order velocity — with no scoring to flag them.
- WordPress-specific abuse vectors, including XML-RPC brute force, plugin/theme tampering, suspicious uploads, and Stripe payment interception, lacked dedicated monitoring.
- A bad actor blocked on one surface could simply stay active on another connected system, because blocking decisions were not shared across platforms.
- Security API endpoints risked being pushed to production without authentication, rate limiting, or input validation hardening.
- Attack patterns and error spikes living only in Nginx logs were invisible to application-level monitoring, and turning on automatic blocking carried the risk of disrupting a live storefront.
Solution highlights
- Built a centralized event-logging service backed by dedicated security event and blocked-IP data models, capturing authentication, suspicious-request, and block/unblock events in one place.
- Shipped an IP blocking service with block, unblock, expiration, and status checks, plus extended blocking to users and email addresses beyond IPs alone.
- Implemented authentication monitoring across login, logout, and failed-login events, with brute-force detection that warns at one threshold and auto-blocks at another.
- Deployed protective middleware for blocked-IP enforcement, rate limiting, security headers, request logging, and suspicious-pattern detection for SQL injection, XSS, and path traversal.
- Delivered an AI Security Agent with tools to query events, block IPs, check IP status, pull metrics, and inspect WordPress events and WooCommerce fraud through natural querying.
- Built a PHP WordPress security connector with a robust API client, retry logic, a local event queue, and a fail-open design, wired into critical hooks for auth, XML-RPC, file integrity, uploads, WooCommerce orders, and Stripe events.
- Created rule-based WooCommerce fraud scoring with defined thresholds and risk levels, flagging high-risk orders on signals like geo mismatch, order velocity, disposable emails, and card-testing patterns.
- Implemented cross-platform blocking so a block applied on one side is automatically reflected on the other connected surface.
- Built a React security dashboard with a live threat feed, incident detail views, emergency lockdown, manual unblock controls, and security metrics, plus email and Slack alerts for critical events.
- Added an Nginx access and error log parser with scheduled background processing that detects attack and DDoS/DoS patterns, suspicious agents, and error spikes, then creates events and can trigger blocking.
Outcomes
- The security team now sees events from the CRM, WordPress, WooCommerce, and Nginx logs in one unified, searchable view with severity badges, filters, and metrics.
- Brute-force and known-bad-IP traffic is detected and blocked automatically once defined thresholds are crossed, shrinking the window of exposure.
- Common injection, XSS, and path-traversal attempts are caught at the request layer, while added security headers reduce the browser-side attack surface.
- Suspicious sessions, malformed auth cookies, and privilege-escalation events are surfaced early, giving the team a chance to act before damage spreads.
- High-risk WooCommerce orders are scored and flagged against clear fraud rules, combining payment-provider signals with business-specific order-risk logic.
- Operators respond faster with a live threat feed, incident details, emergency lockdown, and one-click manual unblock, while email and Slack alerts push critical events to the right people immediately.
- Cross-platform blocking ensures a malicious actor shut out of one system cannot quietly continue operating in another connected surface.
- The WordPress connector's fail-open design keeps the storefront available even if the CRM endpoint is down, so security hardening never takes the shop offline.
- A monitor-only staging rollout let the team validate detection safely before enabling automatic blocking, and background log processing keeps WordPress overhead low.
- Security API endpoints ship production-ready with API-key authentication, rate limiting, and input validation in place.
