10 This page is for **Admin / Engineer** workflows.

12 CoPilot uses **Graylog** as the detection and alerting engine. If Graylog isn’t creating event alerts, CoPilot won’t have anything to ingest into **Incident Management → Alerts**.

18 ## How CoPilot alerting works (Graylog → gl-events* → CoPilot)
19
20 1) Your log metadata is ingested (Wazuh, O365, firewall, third-party, etc.)
21 2) Graylog evaluates **Event Definitions** (your detection logic)
22 3) When a condition matches, Graylog creates an **Event/Alert** and writes it to an index (commonly `gl-events*`)
23 4) CoPilot reads those event alerts and creates/updates alerts in **Incident Management**

27 ## Alert Provisioning (pre-built detections)
28
29 SOCFortress ships a set of **pre-built alert provisioning items** to help you get alerts flowing quickly.
30
31 ![Alert provisioning (placeholder)](../../assets/ui/graylog-alert-provisioning.png)
32
33 Examples visible in the lab:
34 - **WAZUH SYSLOG LEVEL ALERT** — triggers when `SYSLOG_LEVEL = ALERT` (usually set via pipeline when Wazuh rule level is > 11)
35 - **OFFICE365 EXCHANGE ONLINE** — example O365 alert source
36 - **OFFICE365 THREAT INTEL** — O365 threat intel alerts
37 - **CROWDSTRIKE ALERT** — CrowdStrike alerts
38 - **FORTINET SYSTEM / FORTINET UTM** — FortiGate alerts
39 - **PALOALTO ALERT** — Palo Alto alerts
40
41 > These pre-built items assume you have pipeline rules that normalize key fields (for example: setting an `alert_severity` or equivalent “this is an alert” marker).

45 ## Event Definitions (your detection logic)
46
47 Event Definitions are where you define:
48 - the query/conditions
49 - aggregation/time window
50 - when an event should fire
51
52 ![Event definitions (placeholder)](../../assets/ui/graylog-event-definitions.png)
53
54 Operator impact:
55 - Better event definitions → higher signal alerts → less noise in CoPilot.

59 ## Custom alerts (build your own)
60
61 You are not limited to SOCFortress pre-built detections.
62
63 If you can ingest metadata into Graylog, you can create an alert off it.
64
65 Practical examples:
66 - Alert on risky admin actions in Office 365
67 - Alert on firewall activity to known phishing URLs
68 - Alert on anomalous authentication patterns

74 ## Related configuration (ties into Incident Sources)
75
76 After Graylog is firing events, you still need CoPilot to map those events into an operator-friendly alert.
77
78 Next step:
79 - Configure **Incident Sources** (field mappings for title/asset/time/context):
80 - [Incident sources (Graylog → Alerts)](/user/ui/incident-sources)

84 ## Common gotchas
85
86 ### “I configured a Graylog alert, but CoPilot alerts are missing context”
87 That’s typically an **Incident Sources mapping** issue: CoPilot needs to know which fields to treat as title, asset name, and context.
88
89 ### “My detection is firing, but CoPilot shows nothing”
90 Confirm:
91 - the Event Definition actually creates events
92 - events are written to `gl-events*`
93 - CoPilot can read that index (permissions/connectivity)
