SIEM API

Overview

Security Information and Event Management (SIEM) solutions are used by many organizations to identify and correlate various security events occurring in their point products. Examples of SIEM products include HP's ArcSight, IBM's QRadar, and Splunk. 

The API allows integration with these solutions by giving administrators the ability to periodically download detailed information about several types of TAP events in a SIEM-compatible, vendor-neutral format. Currently, the following event types are exposed:

  1. Blocked or permitted clicks to threats recognized by URL Defense
  2. Blocked or delivered messages that contain threats recognized by URL Defense or Attachment Defense

API Features

General Service Notes

  1. All timestamps in the returned events are in UTC.
  2. The API is designed to support different SIEM-compatible formats: Syslog and JSON.
  3. A maximum of one hour of data can be requested in a single transaction.
  4. No paging support is available; all the applicable events in the requested time period will be returned in the log.
  5. The results provided by this API may not be in any logical order.
  6. Requests to the service may be throttled to prevent abuse.
  7. If results cannot be obtained within a timeout period, the service will return an error.
  8. The maximum time into the past that can be queried is twelve hours.

Security

Each request must use:

  • SSL.
  • service credentials to authenticate to the API.
  • the HTTP Basic Authorization method.
  • the HTTP GET method.

Standard Responses

Requests to the endpoints can produce a response with a variety of HTTP status codes. The following table describes the scenarios in which these codes can be produced.

Code Message Scenarios
200 Success At least one record matching the specified criteria was found and returned in the response body. In the case of a JSON format, the structure is always returned, even if empty.

204

No Content

Syslog format only: If no records matching the specified criteria were found, a status code of 204 will be returned with empty content.

400

Bad Request

The request is missing a mandatory "request" parameter, a parameter contains data which is incorrectly formatted, or the API doesn't have enough information to determine the identity of the customer.

401

Unauthorized

There is no authorization information included in the request, the authorization information is incorrect, or the user is not authorized.

403

Forbidden

The user is authenticated for the service but is not authorized to access data for the given customer.

429

Too Many Requests

The user has made too many requests over the past 24 hours and has been throttled.

500

Internal Server Error

The service has encountered an unexpected situation and is unable to give a better response to the request.

Throttle Limits

These endpoints provide methods to fetch information about click and message events for a given time period. The number of queries connected to this resource are limited by a simple, rolling 24-hour throttle. Once exceeded, the API will start returning 429 HTTP status codes until 24 hours past the oldest request has elapsed. Requests to the clicks/permitted API and requests to other APIs are throttled into different pools. This allows more frequent queries to the clicks/permitted API.

Available Endpoints

All endpoints are available on the tap-api-v2.proofpoint.com host—for example, https://tap-api-v2.proofpoint.com/v2...clicks/blocked.

/v2/siem/clicks/blocked

Fetch events for clicks to malicious URLs blocked in the specified time period

/v2/siem/clicks/permitted

Fetch events for clicks to malicious URLs permitted in the specified time period

/v2/siem/messages/blocked

Fetch events for messages blocked in the specified time period which contained a known threat

/v2/siem/messages/delivered

Fetch events for messages delivered in the specified time period which contained a known threat

/v2/siem/issues

Fetch events for clicks to malicious URLs permitted and messages delivered containing a known attachment threat within the specified time period

/v2/siem/all

Fetch events for all clicks and messages relating to known threats within the specified time period

Required Parameters

One of the following three query parameters describing the desired time range for the data must be supplied with each request:

interval

A string containing an ISO8601-formatted interval. If this interval overlaps with previous requests for data, records from the previous request may be duplicated. The minimum interval is thirty seconds. The maximum interval is one hour.

Examples:

  • 2016-05-01T12:00:00Z/2016-05-01T13:00:00Z - an hour interval, beginning at noon UTC on 05-01-2016
  • PT30M/2016-05-01T12:30:00Z - the thirty minutes beginning at noon UTC on 05-01-2016 and ending at 12:30pm UTC
  • 2016-05-01T05:00:00-0700/PT30M - the same interval as above, but using -0700 as the time zone
sinceSeconds 

An integer representing a time window in seconds from the current API server time. The start of the window is the current API server time, rounded to the nearest minute, less the number of seconds provided. The end of the window is the current API server time rounded to the nearest minute. If JSON output is selected, the end time is included in the returned result.

sinceTime

A string containing an ISO8601 date. It represents the start of the data retrieval period. The end of the period is determined by current API server time rounded to the nearest minute. If JSON output is selected, the end time is included in the returned result.

Optional Parameters

One or more of these parameters may also be provided:

format

A string specifying the format in which data is returned. If no format is specified, syslog will be used as the default. The following values are accepted:

  • syslog
  • JSON
threatType

A string specifying which threat type will be returned in the data. If no value is specified, all threat types are returned. The following values are accepted:

  • url
  • attachment
  • messageText
threatStatus

A string specifying which threat statuses will be returned in the data. If no value is specified, active and cleared threats are returned. The following values are accepted:

  • active
  • cleared
  • falsePositive
