The Challenges
Mitigating Web Threats While Maintaining Website Performance
The client’s e-commerce platform, processing a lot of daily transactions, faced growing cybersecurity threats that compromised both security and performance. The following issues represented the most pressing web application protection:
- Rising malicious traffic
frequent bot attacks, SQL injection attempts, and cross-site scripting (XSS) targeted the platform, affecting website availability and user experience. - Inefficient security management
Manually handling security rules required constant monitoring and updates, consuming valuable time and resources. - High operational costs
Excessive alerts and misclassified traffic led to higher operational costs, as legitimate users were sometimes blocked, disrupting the shopping experience.
Without a scalable and automated security solution, the web platform struggled to maintain optimal performance, protect customer data, and reduce security management overhead.
The Solution
Adaptive and Continuous Web Protection with AWS WAF
To fortify web platform security and reduce protection’s operational complexity, AWS WAF our experts implemented a multi-layered strategy, seamlessly integrating with AWS services for real-time monitoring and automated cyber threat mitigation.
Multi-Layered Online Defence with AWS WAF
A comprehensive rule set was deployed to filter and block malicious traffic while maintaining seamless access for legitimate users. Key measures included:
- Bot Control
Blocked harmful bots while allowing legitimate ones, such as search engine crawlers, ensuring SEO integrity and system efficiency. - Managed Rules
Automatically detected and blocked SQL injection, cross-site scripting (XSS), PHP-specific vulnerabilities, and other common exploits, minimizing security risks. - IP Reputation Lists
Proactively blocked requests from known malicious sources, preventing high-risk traffic from reaching the platform. - Geo-Restriction Policies
Prevented transactions from unsupported regions, reducing fraudulent activities and unauthorized access. - Rate-Based Rules
Limited excessive requests to mitigate credential stuffing attacks, preserving platform performance. - Custom Rule Matching
Inspected HTTP request parameters, filtering traffic based on IP addresses, target domains, and request headers to enhance access control. - IP Whitelisting
Ensured secure access for trusted partners and employees, avoiding unnecessary disruptions to business operations. - Application Load Balancer (ALB)
Integrated with ALB at the network edge, filtering out threats before they reached application servers. - Amazon CloudWatch
Enabled real-time monitoring dashboards, capturing and analyzing attack patterns, suspicious activity, and blocked requests for proactive threat management. - Automatic updates of Managed Rules to counter evolving threats, including OWASP Top 10 vulnerabilities, IP reputation changes, malicious logins, and bot attacks.
- Dynamic Rule adjustments allowed continuous fine-tuning of threat prevention measures based on attack trends without impacting user experience.

AWS WAF Implementation FAQ
Infrastructure as Code (IaC) makes it easier to set up and manage AWS WAF by using templates to define rules and configurations automatically. It helps keep settings consistent, speeds up updates, and reduces the chance of manual errors when deploying changes.
AWS WAF Security Automations can detect and block common application-layer attacks such as SQL injection, cross-site scripting (XSS), and bot-based threats. It also helps stop credential stuffing, request flooding, and other Layer 7 attacks that target web application performance and user data.
Yes. AWS WAF automations reduce operational overhead by automatically updating managed rules, adapting to new threat patterns, and minimizing manual rule adjustments. This lets teams focus on higher-priority tasks while maintaining consistent, up-to-date protection.
Real-time monitoring with Amazon CloudWatch gives visibility into traffic patterns, blocked requests, and attack trends. By tracking these metrics, teams can quickly spot unusual activity, adjust AWS WAF rules when needed, and keep application protection effective and reliable.
