# Web Security Guides

Reduce web attack surface with practical controls for applications, APIs, origins, and users.

- [WAF Configuration Guide](/en/guides/waf-configuration.md): A practical WAF configuration guide covering managed rules, safe rollout, exceptions, false-positive analysis, testing, and continuous tuning.

- [Security Headers Checklist](/en/guides/security-headers.md): Use this practical security headers checklist to configure CSP, HSTS, frame protection, MIME protection, referrer controls, CORS, cookies, and reporting safely.

- [Zero Trust Web Apps](/en/guides/zero-trust-web-applications.md): Learn how to apply zero trust to web applications with a practical sequence for identity, resource policy, APIs, service-to-service access, and validation.

- [Agent Spoofing](/en/guides/agent-spoofing.md): Learn how to verify AI agents and crawlers with layered controls, signed requests, IP validation, and route-specific bot policies.

- [TLS and HTTPS](/en/guides/tls-https-web-security.md): A practical guide to TLS, HTTPS, certificates, HSTS, secure headers, edge termination, and the validation steps that keep modern web traffic protected.

- [Protect Your Origin Server](/en/guides/protect-origin-server.md): Learn how to reduce origin exposure with DNS hygiene, gateway-only access, firewall controls, authenticated edge connections, monitoring, and safe testing.

- [DDoS Protection Guide](/en/guides/ddos-protection.md): Understand DDoS protection layers, origin security, traffic controls, observability, and the response preparation required before an attack.

- [Bot vs Human Traffic](/en/guides/bot-vs-human-traffic.md): Learn how to distinguish legitimate people, trusted crawlers, and abusive automation using layered signals, careful response rules, and safe monitoring.

- [Rate Limiting Guide](/en/guides/rate-limiting.md): A practical, provider-neutral guide to rate limiting APIs and web flows by identity, route, and risk without punishing legitimate customers.

- [Secure Webhooks](/en/guides/secure-webhooks.md): A practical guide to secure webhooks: webhook signature verification, webhook replay protection, idempotency, secret rotation, schemas, and safe incident handling.

- [Security Incident Response](/en/guides/website-security-incident-response.md): Build and rehearse a tested security incident response plan for website incidents: roles, evidence, edge provider escalation, customer communication, recovery, and lessons learned.

- [E-commerce Edge Architecture](/en/guides/ecommerce-edge-architecture.md): Design an ecommerce edge that caches public catalog content safely, keeps account and checkout state private, protects origins, and applies layered bot defense.

- [Account Takeover Defense](/en/guides/account-takeover-defense-edge.md): Build layered account takeover defenses across the edge, identity, application, and fraud stack without turning legitimate customers into false positives.

- [Magecart Protection](/en/guides/client-side-script-magecart-protection.md): Protect payment pages from Magecart and e-skimming with script inventory, authorisation, integrity controls, CSP, SRI, tamper detection, and PCI DSS 4.0.1 guidance.

- [Preventing BOLA in APIs](/en/guides/preventing-bola-authorization-failures-apis.md): Prevent broken object level authorization and cross-tenant API exposure with object checks, tenant-scoped data access, adversarial tests, logging, and incident response.

- [Cloud-Native Config and Secrets](/en/guides/cloud-native-config-secrets.md): A practical guide to cloud-native configuration management and secrets management: typed contracts, least privilege, config rotation, Kubernetes safeguards, and operational visibility without leaking credentials.

- [Secure Agent Sandboxes](/en/guides/secure-coding-agent-sandboxes.md): Harden coding agent sandboxes with ephemeral credentials for agents, scoped identity, controlled egress, agent execution isolation, audit evidence, and safe recovery from policy denials.

- [Cloudflare WAF Configuration](/en/guides/cloudflare-waf-configuration.md): A practical approach to Cloudflare WAF configuration: deploy managed and custom rules in stages, with scoped exceptions, API-safe decisions, logging practices, testing, and rollback.

- [Fastly Next-Gen WAF](/en/guides/fastly-next-gen-waf.md): Set up and operate Fastly Next-Gen WAF policies safely with scoped signals and exclusions, request rules, simulation, logging, staged enforcement, and rollback.
