Suricata and Snowflake Integration

Input and output integration overview

This plugin reports internal performance counters of the Suricata IDS/IPS engine and processes the incoming data to fit Telegraf’s format.

Telegraf’s SQL plugin allows seamless metric storage in SQL databases. When configured for Snowflake, it employs a specialized DSN format and dynamic table creation to map metrics to the appropriate schema.

Integration details

Suricata

The Suricata plugin captures and reports internal performance metrics from the Suricata IDS/IPS engine, which includes a wide range of statistics such as traffic volume, memory usage, uptime, and counters for flows and alerts. This plugin listens for JSON-formatted log outputs from Suricata, allowing it to parse and format the data for integration with Telegraf. It operates as a service input plugin, meaning it actively waits for metrics or events from Suricata rather than collecting metrics at predefined intervals. The plugin supports configurations for different metrics versions allowing for enhanced flexibility and detailed data gathering.

Snowflake

Telegraf’s SQL plugin is engineered to dynamically write metrics into an SQL database by creating tables and columns based on the incoming data. When configured for Snowflake, it employs the gosnowflake driver, which uses a DSN that encapsulates credentials, account details, and database configuration in a compact format. This setup allows for the automatic generation of tables where each metric is recorded with precise timestamps, thereby ensuring detailed historical tracking. Although the integration is considered experimental, it leverages Snowflake’s powerful data warehousing capabilities, making it suitable for scalable, cloud-based analytics and reporting solutions.

Configuration

Suricata

[[inputs.suricata]]
  ## Source
  ## Data sink for Suricata stats log. This is expected to be a filename of a
  ## unix socket to be created for listening.
  # source = "/var/run/suricata-stats.sock"

  ## Delimiter
  ## Used for flattening field keys, e.g. subitem "alert" of "detect" becomes
  ## "detect_alert" when delimiter is "_".
  # delimiter = "_"

  ## Metric version
  ## Version 1 only collects stats and optionally will look for alerts if
  ## the configuration setting alerts is set to true.
  ## Version 2 parses any event type message by default and produced metrics
  ## under a single metric name using a tag to differentiate between event
  ## types. The timestamp for the message is applied to the generated metric.
  ## Additional tags and fields are included as well.
  # version = "1"

  ## Alerts
  ## In metric version 1, only status is captured by default, alerts must be
  ## turned on with this configuration option. This option does not apply for
  ## metric version 2.
  # alerts = false

Snowflake

[[outputs.sql]]
  ## Database driver
  ## Valid options: mssql (Microsoft SQL Server), mysql (MySQL), pgx (Postgres),
  ## sqlite (SQLite3), snowflake (snowflake.com), clickhouse (ClickHouse)
  driver = "snowflake"

  ## Data source name
  ## For Snowflake, the DSN format typically includes the username, password, account identifier, and optional warehouse, database, and schema.
  ## Example DSN: "username:password@account/warehouse/db/schema"
  data_source_name = "username:password@account/warehouse/db/schema"

  ## Timestamp column name
  timestamp_column = "timestamp"

  ## Table creation template
  ## Available template variables:
  ##  {TABLE}        - table name as a quoted identifier
  ##  {TABLELITERAL} - table name as a quoted string literal
  ##  {COLUMNS}      - column definitions (list of quoted identifiers and types)
  table_template = "CREATE TABLE {TABLE} ({COLUMNS})"

  ## Table existence check template
  ## Available template variables:
  ##  {TABLE} - table name as a quoted identifier
  table_exists_template = "SELECT 1 FROM {TABLE} LIMIT 1"

  ## Initialization SQL (optional)
  init_sql = ""

  ## Maximum amount of time a connection may be idle. "0s" means connections are never closed due to idle time.
  connection_max_idle_time = "0s"

  ## Maximum amount of time a connection may be reused. "0s" means connections are never closed due to age.
  connection_max_lifetime = "0s"

  ## Maximum number of connections in the idle connection pool. 0 means unlimited.
  connection_max_idle = 2

  ## Maximum number of open connections to the database. 0 means unlimited.
  connection_max_open = 0

  ## Metric type to SQL type conversion
  ## Defaults to ANSI/ISO SQL types unless overridden. Adjust if needed for Snowflake compatibility.
  #[outputs.sql.convert]
  #  integer       = "INT"
  #  real          = "DOUBLE"
  #  text          = "TEXT"
  #  timestamp     = "TIMESTAMP"
  #  defaultvalue  = "TEXT"
  #  unsigned      = "UNSIGNED"
  #  bool          = "BOOL"

Input and output integration examples

Suricata

1. Network Traffic Analysis: Utilize the Suricata plugin to track detailed metrics about network intrusion attempts and performance, aiding in real-time threat detection and response. By visualizing captured alerts and flow statistics, security teams can quickly pinpoint vulnerabilities and mitigate risks.

2. Performance Monitoring Dashboard: Create a dashboard using the Suricata Telegraf plugin metrics to monitor the health and performance of the IDS/IPS engine. This use case provides an overview of memory usage, captured packets, and alert statistics, allowing teams to maintain optimal operating conditions.

3. Automated Security Reporting: Leverage the plugin to generate regular reports on alert statistics and traffic patterns, helping security analysts to identify long-term trends and prepare strategic defense initiatives. Automated reports also ensure that the security posture of the network is continually assessed.

4. Real-time Alert Handling: Integrate Suricata’s alert metrics within a broader incident response automation framework. By incorporating the inputs from the Suricata plugin, organizations can develop smart triggers for alerting and automated response workflows that enhance reaction times to potential threats.

Snowflake

1. Cloud-Based Data Lake Integration: Utilize the plugin to stream real-time metrics from various sources into Snowflake, enabling the creation of a centralized data lake. This integration supports complex analytics and machine learning workflows on cloud data.

2. Dynamic Business Intelligence Dashboards: Leverage the plugin to automatically generate tables from incoming metrics and feed them into BI tools. This allows businesses to create dynamic dashboards that visualize performance trends and operational insights without manual schema management.

3. Scalable IoT Analytics: Deploy the plugin to capture high-frequency data from IoT devices into Snowflake. This use case facilitates the aggregation and analysis of sensor data, enabling predictive maintenance and real-time monitoring at scale.

4. Historical Trend Analysis for Compliance: Use the plugin to log and archive detailed metric data in Snowflake, which can then be queried for long-term trend analysis and compliance reporting.
