A Wazuh coverage report that lists rule 92900 as present and enabled does not prove that the detection works. It proves, at most, that a rule definition is available in the inspected environment. To establish useful coverage, you must show that the relevant event was collected, decoded into the fields the rule expects, matched the loaded rule, became an alert, and appeared in the report or index you are checking.
A Wazuh rule can be correctly installed, enabled, and completely silent for several different reasons. The endpoint may not generate the required event, the agent may not deliver it, the decoder may not extract the expected fields, the event may fail a rule condition, or the alert may be recorded somewhere your report does not query. A genuinely quiet environment is another possibility. Treating all of those situations as “covered” turns configuration inventory into a detection claim.

What a “present, enabled, silent” row actually tells you
Wazuh rules are XML conditions applied to decoded log data. Each rule has an ID and a severity level. A coverage report that lists a rule generally describes configuration state, not end-to-end detection performance.

| Event observed and decoded | An event reached Wazuh and was parsed into fields. | That the relevant rule conditions matched. |
Rule matched in wazuh-logtest |
A representative event can match the loaded decoder and rules in the test context. | Fleet-wide telemetry, production delivery, or indexing. |
| Alert visible in a report or index | An alert was recorded and surfaced in that view and time window. | Complete coverage of related behaviors or every endpoint. |
That distinction is the central lesson of a silent row. A report cannot tell you whether silence means “no attack,” “no telemetry,” “no decoder match,” “no rule match,” or “not visible in this query” unless it exposes those states separately.

What is known about Wazuh rule 92900
The available evidence does not establish one universal, current XML definition for rule 92900. A Wazuh GitHub issue opened June 18, 2026 references a logtest warning involving rule 92900 in version 4.14.5 release candidate 1. That confirms the ID appeared in that reporter’s environment; it does not publish the complete rule or prove that every Wazuh release contains identical conditions.
A third-party incident-response lab report dated May 3, 2026 describes rule 92900 as a level 12 Sysmon process-access alert involving LSASS and gives an example description about LSASS access with read permissions. That is evidence from one lab configuration, not authoritative proof of the current default ruleset, universal availability, or detection of every LSASS-access technique.
Before making a version-specific statement, inspect the ruleset deployed in your own Wazuh installation. Record the Wazuh manager and agent versions, the ruleset revision, and any local overrides. Do not infer exact parent rules, field names, or matching conditions from the rule ID alone.

Wazuh documentation describes data analysis as a sequence in which logs are decoded, rules are triggered, and alerts are generated. For coverage work, turn that sequence into five checks.
1. Configured
Confirm that the intended rule definition is present in the ruleset actually loaded by the manager and that it is not disabled or shadowed by a local customization. Check the deployed version first: a rule documented for one release may differ in another. A configuration export or coverage inventory can support this check, but it should identify the source and version it inspected.
2. Collected
Verify that the endpoint or application can produce the event in question and that its integration is enabled. For the LSASS interpretation associated with rule 92900, that means confirming that Sysmon process-access telemetry is configured and that the relevant event reaches the Wazuh agent. If no raw event arrives, no decoder or rule change can create an alert.

3. Decoded
Inspect what Wazuh extracted from the raw event. A decoder can accept a log while leaving a needed field empty, using a different field name, or parsing a value in an unexpected format. The rule may therefore be present and the source active while the condition never evaluates as intended.
4. Matched
Determine whether a representative event satisfies the loaded rule’s conditions and any parent-rule requirements. Matching can depend on event type, process identifiers, access masks, user or host fields, and other values defined by the deployed XML. Do not substitute a hand-written example for the exact event shape produced in your environment.
5. Observed
Finally, verify that the resulting alert was recorded and is visible in the alert file, index, dashboard, or report being evaluated. A valid match can appear absent when the query uses the wrong time zone, index pattern, host filter, severity threshold, or retention window. “No row” in one report is not proof that no alert exists anywhere in the pipeline.
Step-by-step validation for rule 92900
- Pin the deployment. Write down the manager version, agent version, operating-system edition, Sysmon version and configuration, ruleset revision, and the exact time range used by the report. Include whether the environment is production, a test host, or a lab.
- Inspect the loaded definition. Open the ruleset matching that deployed Wazuh version and locate rule ID 92900. Record its level, description, decoder or parent references, and conditions. If the ID is absent, report that fact instead of assuming a naming or packaging problem.
- Confirm source generation. Check that Sysmon process-access auditing is enabled on the intended endpoints and that the test action produces a raw event. Preserve the raw event with its timestamp and host identity. A configuration screenshot without an arriving event demonstrates readiness, not collection.
- Check agent delivery. Verify that the event leaves the endpoint and reaches the manager or analysis component. Compare the endpoint timestamp with the manager’s receipt time to detect clock skew, buffering, or transport delay.
- Replay controlled data with
wazuh-logtest. Wazuh documents this utility for testing decoders and rules before use. Feed it a representative one-line event, using controlled test data and the same format generated by the endpoint. Capture the decoder output, matched rule ID, and reported level. A successful logtest demonstrates behavior in that test context only. - Compare fields, not just text. Check that the decoded event contains every value the rule expects. If a field is missing or differently normalized, fix collection or decoding before changing the rule. Keep the original raw line and the decoded output together for reproducibility.
- Verify production alerting. Trigger or replay an approved test event in a non-destructive environment, then check the alert record and the downstream index or dashboard. Use a narrow, known time range and search by host and rule ID. Confirm that filters are not excluding the level or rule.
- Document the result by layer. Mark each state separately: raw event present, decoded fields present, rule matched, alert recorded, and alert visible in the evaluated report. Attach the version, configuration, event sample, and query window to the result.
This procedure prevents a successful configuration check from being reported as a measured detection rate. It also gives an operator a clear stopping point: if collection fails, investigate the endpoint; if decoding fails, investigate the parser; if matching fails, inspect the deployed conditions; if recording or visibility fails, inspect alerting and indexing.
How to interpret common report outcomes
| Observed outcome | Most defensible interpretation | Next check |
|---|---|---|
| Rule listed; no raw event | Configured, but collection is unproven. | Endpoint audit settings, Sysmon output, agent integration, and transport. |
| Raw event present; fields missing | Collection occurred, but decoding is incomplete or incompatible. | Decoder selection, event format, field names, and parser errors. |
| Decoded event; no rule match | The representative event did not satisfy the loaded conditions, or a parent requirement was not met. | Rule XML, parent chain, field values, and event type. |
| Logtest match; no production alert | The rule can match in the test context, but delivery, manager processing, recording, or indexing is unproven. | Agent-to-manager path, manager logs, alert storage, and dashboard query. |
| Alert recorded; absent from dashboard | Detection occurred, but the evaluated view did not surface it. | Index pattern, time zone, retention, permissions, and filters. |
| No event during the observation window | The activity may not have happened; detection effectiveness is undetermined. | Use an approved representative test event or extend observation with a defined scope. |
Troubleshooting a missing alert
The endpoint never generated the event
Check whether the required audit or Sysmon configuration is active on that host, whether the process-access event type is enabled, and whether policy differs between test and production machines. A rule aimed at LSASS access cannot alert on telemetry the endpoint does not emit.
The event exists locally but not in Wazuh
Investigate agent collection settings, file or channel permissions, transport status, buffering, and clock differences. Compare the raw endpoint record with what arrives at the manager; do not begin by editing the rule.

The event arrives but does not decode
Verify that the decoder recognizes the event source and that the payload format has not changed. Look for empty, renamed, or differently typed fields. A decoder mismatch can make a correctly installed rule appear silent.
The decoder output is complete but matching fails
Use the exact deployed XML to inspect conditions and parent relationships. Confirm that the test event contains the required access, process, user, and host values. The third-party LSASS description is a useful hypothesis for what to validate, not a substitute for your version’s rule definition.
The rule matches but the report is empty
Search the alert record directly, then verify the index and dashboard query. Check the report’s time zone, severity threshold, host scope, and retention period. A reporting gap should be recorded as an observation-layer failure, not as a detection failure.

Wazuh’s rules documentation describes levels from 0, which is ignored, through 16, the maximum severity. The level expresses how Wazuh classifies a matched rule; it does not indicate how often the rule will match, how much telemetry is collected, or whether every related behavior is detectable. If the lab description of rule 92900 applies to your deployed version, its reported level 12 indicates a high-severity classification in that context, not a benchmarked success rate.
Write coverage claims that the evidence can support
Prefer layered statements over binary labels. For example: “Rule 92900 is present in the Wazuh 4.14.5-rc1 ruleset inspected on this manager; Sysmon process-access events were collected from two test hosts; a representative event decoded and matched in wazuh-logtest; one alert was recorded and visible in the dashboard query for 18 October 2026.” That statement identifies what was actually demonstrated.
A weaker but honest statement is: “The rule is listed and enabled, but no matching event was observed during the stated window.” Do not rewrite it as “the rule is working,” “LSASS access is covered,” or “the rule has a zero false-negative rate.” No independently verified general detection-rate statistic for rule 92900 was identified in the reviewed Wazuh documentation and reports.
Operational checklist
- Identify the exact Wazuh release and ruleset revision.
- Inspect rule 92900’s current XML instead of relying on a copied description.
- Confirm the endpoint source and integration are enabled.
- Save a raw event and its decoded fields.
- Test a representative event with
wazuh-logtest. - Record the matched rule and level.
- Confirm alert recording and downstream visibility separately.
- Preserve host, version, configuration, event, and time-window details.
- Label unverified stages as unknown rather than covered.
The practical conclusion is narrow but important: a present, enabled, silent row is a configuration observation. Coverage becomes a detection claim only when the collection-to-alert path has been demonstrated for the deployed version and the specific telemetry your environment is expected to produce.
