Proofpoint Email Isolation collector

Overview

Proofpoint's Email Isolation solution is a powerful tool for protecting against email-based threats, such as phishing and malware attacks. By isolating potentially dangerous email messages in a secure environment, Proofpoint prevents these messages from reaching end-users and reduces the risk of an attack succeeding.

With Email Isolation, administrators can configure isolation policies based on specific criteria, such as sender reputation, attachment type, or keyword filtering. Isolated messages are stored securely and can be analyzed for threats, providing visibility into potential attacks and allowing organizations to take action to prevent them.

Vendor setup

Minimum configuration required for basic pulling

Although this collector supports advanced configuration, the fields required to retrieve data with basic configuration are defined below.

This minimum configuration refers exclusively to those specific parameters of this integration. There are more required parameters related to the generic behavior of the collector. Check setting sections for details.

Setting	Details
`api_key`	API key

Steps

Action	Steps
Obtain API key	Navigate to Product Settings → Reporting API. The API key can be generated and found in the Isolation Reporting API Console's main viewing panel under Reporting API Key.

Assigning necessary permissions

Only the credentials above are required.

Run the collector

Once the data source is configured, you can either send us the required information if you want us to host and manage the collector for you (Cloud collector), or deploy and host the collector in your own machine using a Docker image (On-premise collector).

Collector services detail

This section is intended to explain how to proceed with specific actions for services.

Browser and email isolation

Internal process and deduplication method

Proofpoint Isolation API stores events up to 30 days in the past. All isolation events are fetched on a polling basis. If there are more events available for a given time period than can be retrieved in a single page (limited to 10,000 records per page), the collector continues to fetch new events until none are available for the query window.

Events are sorted by the date field and deduplicated by comparing the hash signature of the event against previous pulls.

Devo categorization and destination

All events of this service are ingested into the table tap.proofpoint.isolation.url_isolation

Setup output

A successful run has the following output messages for the setup module:

URL isolation

Internal process and deduplication method

Proofpoint Isolation API stores events up to 30 days in the past. All isolation events are fetched on a polling basis. If there are more events available for a given time period than can be retrieved in a single page (limited to 10,000 records per page), the collector continues to fetch new events until none are available for the query window.

Events are sorted by the date field and deduplicated by comparing the hash signature of the event against previous pulls.

Devo categorization and destination

All events of this service are ingested into the table tap.proofpoint.isolation.url_isolation.

Restart the persistence

To restart the service, the user must reconfigure the start_time_in_utc parameter within the configuration file. When the collector is restarted, the system will register the new start time and begin pulling events from that date.

Troubleshooting

This collector has different security layers that detect both an invalid configuration and abnormal operation. This table will help you detect and resolve the most common errors.

Error Type	Error Id	Error Message	Cause	Solution
ApiError	403	API Key XXXXXX is not valid.	Invalid API key	The key is not valid. Please create a new one through the Isolation system.

Collector operations

This section is intended to explain how to proceed with specific operations of this collector.

Verify collector operations

Initialization

The initialization module is in charge of setup and running the input (pulling logic) and output (delivering logic) services and validating the given configuration.

A successful run has the following output messages for the initializer module:

2023-01-10T15:22:57.146    INFO MainProcess::MainThread -> Loading configuration using the following files: {"full_config": "config.yaml", "job_config_loc": null, "collector_config_loc": null}

Events delivery and Devo ingestion

The event delivery module is in charge of receiving the events from the internal queues where all events are injected by the pullers and delivering them using the selected compatible delivery method.

A successful run has the following output messages for the initializer module:

2023-01-10T15:23:00.788    INFO OutputProcess::MainThread -> DevoSender(standard_senders,devo_sender_0) -> Starting thread

Sender services

The Integrations Factory Collector SDK has 3 different senders services depending on the event type to delivery (internal, standard, and lookup). This collector uses the following Sender Services:

Sender services	Description
`internal_senders`	In charge of delivering internal metrics to Devo such as logging traces or metrics.
`standard_senders`	In charge of delivering pulled events to Devo.

Sender statistics

Each service displays its own performance statistics that allow checking how many events have been delivered to Devo by type:

Logging trace

Description

Number of available senders: 1

Displays the number of concurrent senders available for the given Sender Service.

sender manager internal queue size: 0

Displays the items available in the internal sender queue.

Standard - Total number of messages sent: 57, messages sent since "2023-01-10 16:09:16.116750+00:00": 0 (elapsed 0.000 seconds

Displays the number of events from the last time and following the given example, the following conclusions can be obtained:

44 events were sent to Devo since the collector started.
The last checkpoint timestamp was 2023-01-10 16:09:16.116750+00:00.
21 events where sent to Devo between the last UTC checkpoint and now.
Those 21 events required 0.007 seconds to be delivered.

Check memory usage

To check the memory usage of this collector, look for the following log records in the collector which are displayed every 5 minutes by default, always after running the memory-free process.

The used memory is displayed by running processes and the sum of both values will give the total used memory for the collector.
The global pressure of the available memory is displayed in the global value.
All metrics (Global, RSS, VMS) include the value before freeing and after previous -> after freeing memory

INFO InputProcess::MainThread -> [GC] global: 20.4% -> 20.4%, process: RSS(34.50MiB -> 34.08MiB), VMS(410.52MiB -> 410.02MiB)
INFO OutputProcess::MainThread -> [GC] global: 20.4% -> 20.4%, process: RSS(28.41MiB -> 28.41MiB), VMS(705.28MiB -> 705.28MiB)
