Use AI to shorten the investigation, not to guess at a firewall rule
When customers report slow internet and an uplink suddenly fills, the first question is not which IP to block. It is whether the network is experiencing a DDoS attack, an ordinary traffic surge, a routing problem, or a failing device. Blocking the wrong destination can disconnect the customers you are trying to protect.
ISPbills iPilot AI helps an authorized operator investigate registered devices, gather current evidence, and turn findings into a practical response plan. The separate DDoS Protection workspace collects telemetry, tracks attack events, and coordinates configured mitigation integrations. Used together, these tools support a disciplined sequence: observe, explain, approve, act, and verify.
1. Prepare monitoring before an incident
Register the routers and other managed devices that your team is authorized to inspect. Confirm that iPilot can reach them through the configured management connection. Supported commands and available measurements depend on the device, firmware, credentials, and connection type; an unreachable device must remain an explicit gap in the investigation.
In DDoS Protection, complete the network profile, add the prefixes you are authorized to protect, and configure telemetry sources. The product supports source types including sFlow, NetFlow v5/v9, IPFIX, mirrored traffic through a sensor, and supported cloud flow logs. The exporter or sensor still needs to be deployed and correctly connected; selecting a protocol is not a substitute for receiving usable records.
Check the last verified record time, exporter identity, observation direction, and sampling configuration. Compare a normal busy period with a quiet period before tuning bandwidth, packet-rate, and flow-rate policies. A stale collector can produce false reassurance, while a baseline learned during an attack can normalize the wrong behavior.
- Confirm the relevant DDoS entitlement and operator permissions.
- Document essential infrastructure and mitigation exclusions, including management, routing, DNS, and authentication dependencies.
- Keep upstream escalation contacts and the supported blackhole or scrubbing procedure available.
- Start with an operator-reviewed response policy until the integration and recovery process have been tested.
2. Start a read-only investigation in iPilot
In the ISPbills application terminal, /ddos starts a DDoS-focused investigation prompt. It asks iPilot to inspect in-scope devices for traffic spikes, saturated links, CPU load, and connection pressure, and to produce an evidence-based mitigation plan. The shortcut is an investigation entry point, not permission to change every router.
You can also state the request explicitly. Replace the example prefix with your real, authorized scope:
Investigate possible DDoS activity affecting our ISP.
Use read-only checks on the registered edge routers.
Report current interface traffic, packet rates where available,
CPU and connection pressure, timestamps, and unreachable devices.
Separate observed facts from hypotheses.
Do not apply configuration changes.For a narrower incident, name the affected router, link, or service. Ask iPilot to identify the exact device before inspecting it. This reduces ambiguity when several routers have similar names. Fleet-wide checks are read-only; a permitted single-device change is a separate, explicitly approved operation.
3. Correlate device findings with DDoS telemetry
Open the DDoS Protection traffic and attack views and compare the same time window. Interface counters show load and pressure. Flow records help explain destinations, protocols, ports, and traffic concentration. Neither source alone establishes that every packet is malicious.
| Observation | What to investigate | What not to assume |
|---|---|---|
| Bandwidth rises sharply | Destination concentration, normal peak demand, backups, and upstream utilization | High throughput alone proves an attack |
| Packet rate rises while average packets are small | CPU, drops, protocol mix, and forwarding limits | A link below its bandwidth limit is healthy |
| Many apparent sources converge on one address | Target ownership, service impact, and flow direction | Every source address identifies the true attacker |
| Customers complain but flow records are old | Collector reachability, templates, sampling, and export configuration | No recent alert means no incident |
Ask iPilot to organize the findings into a short incident summary: affected target, observation time, traffic signature, customer impact, confidence, missing evidence, and next safe check. If detailed flow evidence is only available in the DDoS workspace, provide the relevant non-sensitive summary rather than assuming the assistant has automatically read every chart.
4. Choose the smallest response that addresses the bottleneck
The correct response depends on where capacity is being exhausted. A local filter can protect a service or router only when traffic can still reach that control point without already overwhelming the upstream circuit. If a transit link is saturated, contact the upstream provider or the configured scrubbing service: dropping traffic after the congested link does not recover that link’s capacity.
| Response | When it may help | Trade-off to review |
|---|---|---|
| Narrow local filtering or rate control | A verified traffic signature and available local capacity | Legitimate traffic matching the rule may also be affected |
| RouterOS local blackhole | Isolating an exact destination at the configured router | The destination loses legitimate traffic too; upstream congestion may remain |
| Upstream RTBH | A provider supports and accepts the agreed blackhole route | The targeted address is deliberately made unreachable through that path |
| Scrubbing integration | A contracted, configured service can divert and clean the traffic | Routing, capacity, service coverage, and return-path requirements must be verified |
| Webhook or notification | Coordinating an external response workflow | A delivered notification is not proof that a filter was installed |
ISPbills response connectors must be configured and ready. Observe-only connectors do not execute mitigation. A connector’s availability does not certify every router model, firmware release, or upstream network; verify the particular integration before relying on it during an outage.
5. Require a clear plan, approval, and a way back
Before a configuration change, ask iPilot for the exact device and target, intended commands, expected effect, affected customers, expiry, verification checks, and rollback procedure. Save a configuration checkpoint or backup appropriate to the device. Keep out-of-band access available when a change could affect management connectivity.
Prepare a mitigation plan for the verified affected destination.
Explain the evidence, expected customer impact, and upstream dependency.
Include a checkpoint, exact scope, expiry, success checks, and rollback.
Do not execute until an authorized operator approves this specific change.The DDoS workspace supports manual, single-approval, dual-control, and verified-automatic response policies. These are not interchangeable. In dual control, two distinct authorized responders are required. Eligible automatic responses still depend on monitoring state, a ready automatic connector, critical detection confidence, protected scope, and essential-address safeguards. Do not enable automatic response simply because an AI explanation sounds convincing.
6. Verify service recovery, then withdraw carefully
After an approved response, inspect both control-plane status and the actual network. A queued request is not an installed route; an installed rule is not automatically a recovered service. Check the connector result, current traffic, router pressure, legitimate customer reachability, and upstream behavior.
For example, if interface utilization falls but every customer sharing the targeted NAT address goes offline, the action reduced traffic without meeting the service objective. That is a reason to reassess scope, not to declare success.
When the incident subsides, withdraw temporary mitigation through the supported recovery workflow and watch for recurrence. Confirm that expiry or rollback actually removed the response. Retain an incident record containing the evidence window, approvals, configuration change, observed result, and recovery time.
Prevent the next incident from becoming a larger outage
Prevention is layered. Restrict management access, keep device software maintained, avoid operating open amplification services, apply appropriate source-address validation at customer boundaries, and establish upstream response arrangements. BCP 38 source validation reduces spoofed traffic leaving a network; it does not stop every flood arriving from valid source addresses. Routing asymmetry and multihoming need to be considered before choosing a filtering method.
Use iPilot periodically to review registered-device health and investigate anomalies before they become customer-wide incidents. Keep a clean traffic baseline, review essential-address exclusions, and rehearse a controlled response with your upstream. No AI assistant can promise complete DDoS prevention, but faster evidence gathering and safer decisions can reduce avoidable disruption.
Frequently asked questions
Does typing /ddos automatically block an attack?
No. It starts a DDoS-focused investigation in the application terminal. Network changes require a separate permitted workflow and the applicable approval. Always check the actual response result.
Can iPilot protect a saturated upstream link by adding a router rule?
Not by filtering only after that link. Upstream filtering, RTBH, or a suitable scrubbing path may be required. Coordinate with the provider before an incident.
Should every suspicious source IP be blocked?
No. Spoofing, reflection, shared services, and incomplete sampling can make source attribution misleading. Validate the target, traffic signature, and blast radius first.
