PROTECTION / THE OPERATING BOUNDARY

Evidence at your origin.
Actions you can inspect.

Hostwatch connects server health, recorded HTTP behavior and scoped origin controls. Traffic reaches your infrastructure through the network and edge services you choose.

01Internet02Upstream03Origin04Application
01 / EVIDENCE

Repeated sensitive-path probes, URL enumeration and exploit-endpoint discovery in recorded HTTP evidence.

02 / RESPONSE

Investigate the source and route. With the Nginx actuator configured, preview a temporary client limit or deny.

03 / BOUNDARY

A probe is evidence of behavior. It does not prove an exploit succeeded.

Illustrated workflows. Your available evidence and actions depend on the agent, logging, application integration and enabled policy.

CAPABILITY MAP

Different problems.
Different responses.

Availability depends on supported agents, configured logging, trusted identity and enabled controls. The detector catalog includes ten suspected HTTP behaviors and three capacity observations. These are distinct evidence patterns; they do not establish thirteen proven DDoS types.

Configured response

Scanning & sensitive-path discovery

Recorded known-path probes, URL enumeration, secret/repository discovery, CMS/login discovery and exploit/debug endpoint probes.

Response

Investigate the caller, service and destination route. Preview a temporary client limit or deny with the Nginx actuator configured.

Configured response

HTTP floods & route pressure

Distributed URL and route floods, dynamic-route pressure and repeated probe pressure, assessed with collection coverage and measured harm.

Response

Review route rate limits and concurrency budgets. Inspect the active generation, rule expiry and attributed rejected or delayed requests.

Application integration

Account & device allowances

Trusted identity supplied by your application distinguishes subscriber, test-access, signed-in and public admission checks.

Response

Configure account and device limits alongside network controls. A shared IP or paired device key alone cannot establish subscription status.

Capacity observation

Crawler or expensive-route overload

Verified crawler pressure, expensive routes and unexplained traffic surges are tracked separately from suspected malicious activity.

Response

Review crawler budgets or route limits against service impact. A high request count alone does not establish an attack.

Signal only

SYN, UDP & ICMP pressure

Supported Linux agents read IPv4 kernel counters and sustained host pressure. These are node-wide observations, without packet-level attacker attribution.

Response

Investigate the server and involve the network provider. Hostwatch does not install a packet-filter rule from these pressure signals.

Extra evidence required

Credential attacks & application exploits

Credential stuffing needs trusted authentication results and account diversity. SQL injection, XSS and command injection need WAF or application rule evidence.

Response

Integrate authentication and WAF evidence. Path probes alone cannot establish credential stuffing or a successful application exploit.

Extra evidence required

Slow HTTP, TLS & reflection attacks

Slow-client occupancy and request-age evidence, TLS handshake measurements or packet/flow records are needed for reliable classification.

Response

Use the relevant server, application or network controls. These attack types are not currently provided as verified Hostwatch detections.

Upstream required

A saturated network link

A volumetric attack can exhaust the uplink before requests reach the origin agent.

Response

Use your hosting or edge provider’s upstream DDoS protection. Hostwatch operates outside the request path and provides no CDN, Anycast or volumetric scrubbing capacity.

BEFORE A RULE CHANGES

Scoped, reviewed
and attributable.

  1. Understand the evidence. Review request coverage, service harm and client identity. Retained examples can cover only part of a window.
  2. Preview the action. Manual policy is the default. Automatic actions require explicit delegation, fresh evidence and an enabled policy.
  3. Protect ordinary clients. Automatic shared route ceilings are suppressed for indistinguishable one-shot distributed clients. Login and payment routes can have protected-route policies.
  4. Verify the result. Attribute mitigation to an active rule and matching evidence. A 429 or 444 response by itself does not prove protection. Temporary rules expire and can be rolled back.
Choose the right protection layer.

Hostwatch complements upstream protection, application authentication and a configured WAF. It does not bundle a managed OWASP ruleset, global bot reputation or browser challenges. No independently validated Gbps, packets-per-second or false-positive guarantee is advertised.

Local agents and existing rules keep running if the central control plane becomes unavailable. New remote actions and fresh Cloud views require connectivity and the appropriate entitlement.
