A). Instance size: While important, it depends on specific traffic volume and complexity. Misconfigured or overly generic rules can cause performance issues even on large instances.C. Enabling all rulesets: This "catch-all" approach can block legitimate traffic and create unintended consequences. Tailoring rules based on your application,s specific needs is crucial.D. Cost-efficiency: While important, choosing the cheapest instance may lead to insufficient protection if it can,t handle your traffic or lacks needed features. Balancing cost with effective security is key.Why custom WAF rules are critical:
Targeted protection: Generic rulesets might not cover your application,s unique vulnerabilities. Custom rules ensure protection against specific threats targeting your application logic.
Reduced false positives: Overly broad rules can block legitimate traffic, impacting user experience and requiring manual overrides. Custom rules minimize false positives while maintaining security.
Improved performance: By tuning rules to your needs, you can avoid unnecessary processing overhead and optimize WAF performance.
