Abstract

With the increasing frequency and sophistication of cyberattacks, web-based businesses require a cohesive and practical security architecture to safeguard critical systems and data. This paper examines the integration of firewalls (pfSense, Cisco ASA), intrusion detection and prevention systems (Snort, Suricata), and vulnerability scanners (OpenVAS) as core components of a defense-in-depth strategy. Firewalls serve as the first line of defense by controlling network access, while IDS/IPS tools provide real-time monitoring and response to threats such as malware and brute force attempts. Vulnerability scanners identify system weaknesses that may otherwise go unnoticed. We explore integration techniques, including centralized monitoring, configuration alignment, and architectural compatibility, along with deployment challenges such as complexity and false alarms. Through case studies in e-commerce and other online services, we demonstrate how combining these tools can enhance security posture, support regulatory compliance (e.g., GDPR, HIPAA), and improve operational resilience without incurring excessive costs.
