Revision as of 15:26, 22 November 2018
An Observer GigaFlow Event is a record that is created when a monitored flow pattern matches certain criteria.
Contents |
What Generates an Event?
Some things that will trigger an event record include:
- Attempts to access blacklisted resources.
- Profile exceptions, i.e. behaviours deviating from norms.
- A SYN flood event.
- A lost neighbour.
- A new connected device sending flows.
- A connected device that stops sending flows.
See the Event definition in the Glossary and the main entry for Events in the Reference Manual
What is Recorded?
All GigaFlow flow records contain 29 fields or table columns. In the myipfix database associated with the GigaFlow installation, the netflow tables contain all flow records. See Flow Record Fields for the complete list.
Similarly, the Events tables contain all the Event records. See Event Record Fields for a complete list with descriptions. The Event record fields are:
id, customerid, device, firstseen, eventtype, eventsrctype, eventsrc, message, datatype, data, datasource, confidence, severity, category, target, country_src, division_src, latit_src, longd_src, country_dst, division_dst, latit_dst, longd_dst
Three events have both eventtype and posture set in the netflow and event tables in the database, i.e. these three event types can be determined immediately from Netflow records:
Record Field | Type | Code | Description |
postureBlackListSrc | int | -11 | Attempted access by blacklisted resources. See also Watchlists in the Reference Manual. |
postureBlackListDst | int | -12 | Attempted access to blacklisted resources. See also Watchlists in the Reference Manual. |
profilerException | int | -20 | Profile exceptions, i.e. GigaFlow administrator-defined behaviours deviating from norms. See also Profiling in the Reference Manual. |
In addition, all of these event types have only eventtype set in the event tables, i.e. these event types are classified with additional information or information from many records and have no postureid set in the netflow tables:
Record Field | Type | Code | Description |
synSrc | int | -100 | SYN Source Network Sweep. See also SYN Forensics Monitoring in the Reference Manual. |
synSrcPortException | int | -101 | SYN Source Port Sweep. See also SYN Forensics Monitoring in the Reference Manual. |
synSrcIPException | int | -102 | SYN Source Unreachable IP. See also SYN Forensics Monitoring in the Reference Manual. |
synSrcIPAndPortException | int | -103 | SYN Source Network And Port Sweep. See also SYN Forensics Monitoring in the Reference Manual. |
synDst | int | -120 | SYN Destination Network Sweep. See also SYN Forensics Monitoring in the Reference Manual. |
synDstPortException | int | -121 | SYN Destination Port Sweep. See also SYN Forensics Monitoring in the Reference Manual. |
synDstIPException | int | -122 | SYN Destination Unreachable Server. See also SYN Forensics Monitoring in the Reference Manual. |
synDstIPAndPortException | int | -123 | SYN Destination Network And Port Sweep. See also SYN Forensics Monitoring in the Reference Manual. |
lldpNewNeighbour | int | -130 | A new connected device sending flows. |
lldpLostNeighbour | int | -131 | A lost neighbour. |
deviceRestartsSendingFlows | int | -150 | A connected device that stopped sending flows restarts sending flows. |
deviceStopsSendingFlows | int | -151 | A connected device that stops sending flows. |
How are the Records Accessed?
Data can be accessed:
- As a normal user, via the GigaFlow interface. See Events in the Reference Manual.
- As an automated portal user, via the GigaFlow API. See Forensic Data Using the API.
- From the database directly using a viewer such as pgAdmin or in code using a postgreSQL connector such as Psycopg2 for Python.
Sample Records
Typical records from an Event table with obfuscated IP addresses and locations:
