Pre‑event security checklist for streaming platforms: WAF, rate limits, autoscaling, threat intel, and on‑call runbooks to survive massive live traffic.

Preparing for High‑Profile Traffic: Security and Observability Checklist Inspired by JioHotstar’s 99M Viewers

Hook: You have one shot to survive a global live event. When 99 million concurrent viewers hit a stream — as JioHotstar did during a recent cricket final — gaps in WAF rules, rate limits, auto‑scaling, or runbook readiness don’t just cause slow pages; they cascade into reputation damage, blacklists, and long remediation cycles. This checklist gives DevOps, SREs, and security teams an operational, pre‑event playbook to prevent outages, contain abuse, and restore confidence within minutes — not days.

Before the first kickoff, prioritize three capabilities: edge hardened delivery (CDN + origin protection + WAF), predictable scaling (warm pools + pre‑provisioned resources + autoscaling policies), and real‑time detection + human escalation (observability + threat intel + on‑call runbooks). If any one of these is weak, a spike becomes a crisis.

Real-world trigger: a streaming platform can absorb 99M viewers if upstream caches and WAF rules block malicious floods at the edge and teams have pre‑staged capacity and clear escalation playbooks.

Why 2026 is different — five trends that change preparation

AI‑driven abuse: By 2025–2026 automated, adaptive bots now mimic human navigation and bypass simple CAPTCHAs; detection needs behavioral analytics and ML‑based bot management.
Edge compute and QUIC adoption: Edge-first hosting and micro-region economics and HTTP/3/QUIC for live segments reduce latency but expose new observability blind spots at the edge.
Supply chain and API attack surface: Streaming stacks increasingly depend on third‑party adtech, analytics, and DRM services; these introduce new vectors and require SCA and contract SLAs. See guidance on patch and supply-chain hygiene for operational parallels.
Threat intel automation: Real‑time STIX/TAXII and automated feeds and API feeds are now standard for feed‑to‑WAF automation — manual lists are obsolete.
Regulatory scrutiny and privacy constraints: Geo‑privacy and data‑localization rules affect CDN and logging configuration; prepare compliant observability that still gives actionable telemetry. See calendar and scheduling patterns for observability in Calendar Data Ops.

Pre‑Event Checklist — Executive summary (1‑page actionable)

Runload simulation at 1.5–2x expected peak concurrency across CDN, origin, and auth layers.
Pre‑warm CDN, transcoder pools, and DB read replicas; establish warm node pools and reserved capacity quotas.
Deploy hardened WAF rules & bot mitigation at the edge with feed‑driven blocklists.
Implement multi‑layer rate limits (edge, API gateway, origin) and dynamic throttling policies.
Enable real‑time threat intel ingestion (STIX/TAXII, MISP, commercial feeds) into WAF, SIEM, and CDNs.
Pre‑publish an on‑call runbook and perform a tabletop drill with SRE, SecOps, and product leads.
Set SLOs, error budgets, and synthetic tests for the live path; register dedicated dashboards for the event.

Detailed Preparations and Why They Matter

1) WAF Rules and Edge Hardening

Goal: Stop malicious requests at the edge so origin resources focus on legitimate traffic.

Apply deny‑by‑default for unrecognized API endpoints during the event window; only allow routes needed for streaming and essential APIs.
Use layered WAF policies: global rate limits at CDN, application rules at WAF, and API‑gateway validation for signed tokens.
Deploy adaptive rules that escalate on anomalous patterns — e.g., sudden spike in /login attempts or unusual query strings. Implement automated rule promotion with human approval paths.
Integrate ML‑based bot mitigation (behavioral device fingerprinting, browser challenge, JS score) rather than relying on static IP lists alone — AI bots defeat legacy techniques.
Preconfigure cookie/signature validation and signed URLs for time‑limited content to reduce origin load and hotlinking.

Actionable WAF checklist

Create a minimal allowlist for streaming manifests and playback endpoints.
Enable OWASP Core Rules with tailored exceptions for known high‑volume legitimate patterns.
Automate blocklist updates via STIX/TAXII or vendor APIs (abuse IPs, emerging bot networks).
Test rule efficacy with synthetic attacker traffic and replay telemetry through WAF in non‑blocking mode before enforcement.

2) Rate Limits, Throttling, and Backpressure

Goal: Preserve the service experience for real users by applying deterministic controls on abusive or misbehaving clients.

Layer rate limits: CDN per‑IP, gateway per‑API key, and origin per‑session. Use token buckets with burst allowance tuned for video startup behavior.
Implement dynamic throttling that uses load signals (CPU, queue length, error rate) to tighten limits automatically when the backend is strained.
Use graceful degradation: lower quality levels, disable non‑essential APIs, or shift to audio‑only streams under pressure.
Design client SDK fallbacks that respect Retry‑After headers and exponential backoff to avoid thundering herd retries.

Actionable rate limit rules

Allow higher RPS for playback start URLs; stricter limits for sign‑in, search, and comment endpoints.
Block or quarantine clients violating behavioral thresholds (e.g., >100 requests/min to auth endpoints).
Enable a circuit breaker that returns 503 with Retry‑After during sustained backend overload and logs the context for postmortem.

3) Auto‑scaling, Warm Pools, and Capacity Planning

Goal: Ensure compute, network, and transcode capacity scale predictably and fast enough to meet peak demand.

Pre‑provision warm pools for stateful resources (transcoders, DRM license servers, auth caches). Use instance refresh and AMI baking to reduce cold‑start variability.
Set autoscaler policies that prioritize horizontal scaling with predictive algorithms rather than reactive triggers only. Use scheduled scaling to cover the expected window.
Verify cloud account quotas and increase them pre‑event. Test BGP Anycast paths if using multi‑CDN routing and ensure peering and origin shield are ready.
Use request collapsing (de‑duplication) at the edge for repeated identical manifest requests and OPFs to reduce cache misses.

Key capacity metrics to validate

Cache hit ratio at CDN and origin shield > 95% for manifests and startup assets.
Time to provision a warm node < 60s for critical components.
Percent of requests served from edge vs. origin during load test.

4) Observability — Telemetry You Must Have

Goal: Get high‑fidelity, correlated telemetry across edge, app, and infra so triage is fast and precise.

Instrument with OpenTelemetry traces, eBPF network metrics for kernel‑level flows, and high‑cardinality logs for session IDs.
Create an event map/dashboard showing user sessions by geography, CDN POP, playback status, error code distribution, and origin latency.
Deploy synthetic monitors and real‑user monitoring (RUM) for the event path; prioritize metrics: time‑to‑first‑frame, buffering rate, and startup success.
Set concrete SLOs: e.g., 99.9% of sessions should start within 5s, buffering incidents <0.1% of playback minutes. Convert SLO breaches into automatic mitigation triggers.

Observability checklist

Pre‑built dashboards for the event: playback funnel, CDN hit/miss, WAF blocks, auth failures, and DB latencies.
Alerting rules with severity mapped to runbook actions and Slack/ops channel routing.
Correlation keys (session_id, request_id) propagated across CDN, gateway, and origin for fast root cause analysis.

5) Real‑time Threat Intel Ingestion and Automation

Goal: Feed current threat signals into enforcement points in minutes, not hours.

Integrate STIX/TAXII and MISP subscriptions into the WAF and SIEM to auto‑push IOC updates for IPs, ASNs, and URLs.
Use vendor feeds for botnets and credential stuffing; normalize and rank feed entries by confidence before enforcement.
Automate triage playbooks: suspicious IPs → challenge → if confirmed malicious → block across CDN and API gateway.
Maintain a whitelist of partner and vendor IP ranges to prevent false positives during the event.

6) Bot Mitigation and Credential Stuffing Defenses

Goal: Protect auth flows, payment endpoints, and comment systems from automated abuse without degrading UX for real users.

Use behavior‑based bot scoring and risk‑based MFA for high‑risk flows. Avoid blanket CAPTCHA on playback start.
Throttle login attempts and require progressive proof (JS challenge → fingerprint → MFA) as risk increases.
Monitor for large credential stuffing waves with anomaly detectors and feed suspected IPs to the edge for temporary challenge isolation.

7) Session Affinity and State Management

Goal: Maintain playback continuity under load while allowing effective scaling.

Prefer stateless tokens for playback authentication (JWTs, signed URLs) so edge POPs can validate without origin calls.
If session affinity is required for stateful transcoders, use consistent hashing and sticky session timeouts that match expected stream length.
Design fallback for session migration if a node fails: short‑lived checkpoints, client resumable tokens, and session reconciliation mechanisms.

8) On‑Call Runbook and Tabletop Drills

Goal: Ensure rapid, coordinated human response when automation hits limits or requires judgment calls.

Every event must have an explicit runbook published and rehearsed. Below is a condensed, actionable runbook template your team can adopt and adapt.

On‑Call Runbook Template (condensed)

Initial detection: Alert fires => Triage lead acknowledges within 2 minutes and posts incident stub to the war room (Slack/Zoom).
Immediate containment (0–5 minutes): If WAF error rate spikes or origin error rate > 5%, apply temporary stricter edge policies: enable JS challenge, tighten CDN per‑IP RPS.
Assess impact (5–15 minutes): Run dashboard checklist — playback success, cache hit ratio, auth error rate, and geographic distribution. Tag affected customers.
Escalation (15–30 minutes): If degradation persists, invoke senior SRE, SecOps, and Product (pre‑assigned pager rota). Open postmortem artifact and start timeline tracking.
Mitigation & communication (30–60 minutes): Implement longer‑term mitigations (auto‑scale triggers, pre‑warmed nodes), and publish status updates to stakeholders and status page every 15 minutes.
Recovery & restore (60+ minutes): Gradual rollback of restrictive controls only after verified recovery of SLO metrics; maintain elevated monitoring for 24–72 hours.
Postmortem: Capture timeline, root cause, detection gaps, and action items within 72 hours; run a follow‑up audit of pre‑event readiness.

9) Communications and Legal Considerations

Pre‑authorise status messaging templates for internal ops, customers, and regulators for faster, consistent comms during incidents.
Have legal and privacy teams on standby for potential GDPR/PDPA questions related to logging and user data retained during forensic analysis.
Record and preserve forensic telemetry in an immutable store (WORM) with retention aligned to compliance needs. Consider architectures for high‑volume telemetry like ClickHouse for scraped data as part of your pipeline.

10) Post‑Event Actions and Continuous Improvement

Immediately run a replayable chaos/forensic simulation to validate the postmortem fixes. See notes on chaos engineering vs process roulette.
Convert rule changes into code (IaC) and store them in the event runbook repository with signed approvals.
Schedule a 30/60/90 day follow up to reassess SLOs, threat intel efficacy, and warm pool sizing for future events.

Operational Examples & Minimal Configuration Templates

Below are concise, practical configurations and templates you can implement quickly.

Minimal WAF policy flow

Edge rule: block known bad ASN/IP with high confidence.
Edge rule: JS challenge for clients with anomalous UA/device fingerprint.
API gateway rule: validate signed playback token and rate limit per token.
Origin rule: require X‑Forwarded‑For and origin shield header to prevent hotspotting.

Autoscaling pre‑warm plan (example)

Estimate peak concurrency and convert to required transcoder units (e.g., 99M viewers => X simultaneous streams based on average watch time & CDN edge offload).
Reserve 20% of peak as warm pool. Set autoscaler minimum = warm pool, scale up threshold CPU 60% sustained, scale down grace 15 min after event.
Validate warm nodes with health probes and load test scripts one week and one day ahead.

Metrics and KPIs to Watch During the Event

Playback startup time, buffering ratio, and mean time to first frame.
Edge WAF rule triggers and false positive rate.
CDN cache hit/miss ratios and origin request volume.
Auth success rate and login error spikes.
Error budget burn rate and incident duration.

Prepare for Edge Cases — What Often Breaks

Third‑party SDKs (ads, analytics) that cause synchronous blocking on startup — have a fast disable toggle.
Unexpected client‑side retries flooding APIs — ensure client throttling is implemented in SDKs.
Misconfigured CDN caching that bypasses origin shield for manifests — pretest TTLs and cache keys.
False positive WAF blocks during spikes — use staged enforcement and quick rollback paths in IaC. For lessons learned from major incidents, see postmortem analysis.

Final Checklist (Action Items — 48–72 hours before)

Run a full dry‑run with synthetic traffic at 1.5–2x projected peak. Reference the Edge‑First Live Production Playbook for live production specifics.
Confirm CDN pre‑warm and origin shield configuration; validate cache hit target.
Publish and rehearse on‑call runbook; verify pager rotations and escalation contacts. Use calendar and scheduled automation to ensure rotations and drills run reliably.
Validate WAF and bot mitigation in monitoring (non‑blocking) mode; then apply enforcement window.
Ensure threat intel feeds and automation pipelines are active and correctly feed enforcement points.
Pre‑stage rollback plans and IaC change approvals for emergency rule updates.
Design customer communications and status page templates; schedule the comms owner.

Concluding Advice — Treat the Event as a Continuous Delivery of Trust

Big live events like those that drove JioHotstar to 99 million viewers are a stress test of your entire stack — not just your CDN. In 2026 the difference between a smooth event and widespread outages is how well you automate intelligence into enforcement, pre‑stage capacity, and bind human decision paths to telemetry. Focus on the three pillars for success: edge enforcement, predictable capacity, and fast human workflows. If you can prove those three under load, you’ve engineered trust.
