all external endpoints. • Common mistake: leaving endpoints unprotected. • Apply AWS WAF to every external endpoint? • Automate detection of new public endpoints (e.g., ELBs). • Set up alerts for newly created endpoints. • Maintain seamless protection as your setup grows.
Split Web ACLs by traffic or application type. • Avoid putting all rules in one ACL. • Use separate ACLs for standard traffic and APIs. • Easier to manage and adjust rules. • More flexibility and better control. → Use a dedicated Web ACL for admin portals with customized IP allowlists or geolocation restrictions.
Production • Test Web ACL rules before production deployment. • Ensure rules don’t block legitimate traffic. • Simulate real-world traffic, including edge cases. • Use count mode to track rule impact without blocking. • Identify and fine-tune rules before enforcing them.
and store AWS WAF traffic logs. • Logs provide insights into requests, threats, and traffic patterns. • Store logs in a separate AWS account for better security and compliance. • Set specific log retention policies to match organizational needs. • Use Amazon S3 for storage or analyze logs with CloudWatch and Athena. • Maintain visibility into web app security while optimizing costs.
monitor AWS WAF traffic. • Watch for abuse activities, like attacks from EC2 instances. • Regularly review logs and alerts to detect malicious patterns. • Take immediate action if abuse is detected. • Report abuse to cloud providers or companies for resolution.
Many Than None at All • Set up alerts for WAF events and activities to ensure strong security. • Stay informed about threats and unusual traffic patterns for timely responses. • Use AWS CloudWatch to create alarms for metrics like blocked request spikes. • Integrate with AWS SNS, AWS ChatBot, and Systems Manager Incident Manager for real-time notifications.
abusive traffic and DDoS attacks. • Use AWS WAF rate-based rules to limit requests per IP within a set timeframe. • Prevent single users from overwhelming your application. • Monitor rate-limiting metrics regularly to adjust thresholds. • Adapt thresholds to match your application's traffic patterns. • Enhance resilience while ensuring a good experience for legitimate users.
AWS WAF rules to maintain strong security. • Threat landscapes evolve; update rules to address new vulnerabilities. • Schedule periodic evaluations of your existing rules. • Analyze logs for patterns indicating the need for adjustments or new rules. • Adapt rules to emerging attack vectors and technologies. • Keep rules current to strengthen defenses and stay ahead of attackers.
Control to detect and mitigate unwanted bot traffic. • Identify automated traffic patterns and block or challenge bad bots. • Allow good bots, like search engine crawlers, to access your application. • Regularly review Bot Control insights to adapt to evolving bot behaviors. • Maintain application performance by preventing malicious automated activities. • Enhance security while keeping legitimate traffic unaffected.
