Duo collector

Overview

Duo Security is a cloud-based access security provider that offers multi-factor authentication (MFA), endpoint security, and remote access solutions to protect users and their devices against unauthorized access and cyber threats. It is designed to ensure that only authorized users and secure devices can access applications and data, regardless of where the applications or users are located.

Duo collector migration guide

This guide will walk you through the process of updating your configuration from versions <2.0.0 to versions 2.x.x. This version introduces significant improvements and changes to the configuration style to enhance performance, usability, and security.

Versions 2.x.x are incompatible with previous versions (1.x.x). New versions need some adjustments to the configuration file to ensure a smooth migration process. The following sections will guide you through the necessary steps to update your configuration.

Preparing for migration

Before starting the migration process, we recommend the following steps:

1. Backup your current configuration: Make sure you have a backup of your existing configuration files to prevent any data loss.

2. Review the new configuration documentation: Familiarize yourself with the new configuration options available in version 2.x.x.

Migration steps

Step 1: Update credentials

An example of the old and new configuration is shown below:

Step 2: Update start date

An example of the new configuration is shown below:

The <start_datetime_utc_value> has the format "YYYY-MM-DDTHH:MM:SS.000Z". For example, a valid start_datetime_utc_value would be "2024-07-01T00:00:00.000Z".

Devo collector features

Data source description

This collector extracts data from 3 log services available from Duo:

• Administrator: Returns a list of administrator log events.

• Authentication: Returns a paged list of authentication log events.

• Telephony: Returns a list of telephony log events.

API limits

• Administrator:

  • Only the 1000 earliest events (maximum) will be returned with each page; the collector will be called multiple times to page through the entire log.

  • The recommended limit suggests requesting logs no more than once per minute.

• Authentication:

  • Returns a paged list of authentication log events ranging from the last 180 days up to as recently as two minutes before the API request. There is an intentional two minute delay in availability of new authentications in the API response. Duo operates a large scale distributed system, and this two minute buffer period ensures that calls will return consistent results. Querying for results more recent than two minutes will return as empty.

  • The recommended limit suggests requesting logs no more than once per minute.

• Telephony:

  • Returns a paged list of authentication log events ranging from the last 180 days up to as recently as two minutes before the API request. There is an intentional two minute delay in availability of new telephony events in the API response. Duo operates a large scale distributed system, and this two minute buffer period ensures that calls will return consistent results. Querying for results more recent than two minutes will return as empty.

  • The recommended limit suggests requesting logs no more than once per minute.

Minimum configuration required for basic pulling

Although this collector supports advanced configuration, the fields required for basic data pulling are below.

Treat your secret key like a password

The security of your Duo application is tied to the security of your secret key (skey). Secure it as you would any sensitive credential. Don't share it with unauthorized individuals or email it to anyone under any circumstances.

Connectivity requirements

This application communicates with Duo's service on SSL TCP port 443. Firewall configurations that restrict outbound access to Duo's service with rules using destination IP addresses or IP address ranges aren't recommended, since these may change over time to maintain our service's high availability. If your organization requires IP-based rules, please review Duo Knowledge Base article 1337. Effective June 30, 2023, Duo no longer supports TLS 1.0 or 1.1 connections or insecure TLS/SSL cipher suites. See Duo Knowledge Base article 7546 for additional guidance.

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.

For all the services

Devo categorization and destination

Please check the section Data Source Description to learn about the target tables for each service.

Restart the persistence

This collector uses persistent storage to download events in an orderly fashion and avoid duplicates. In case you want to re-ingest historical data or recreate the persistence, you can restart the persistence of this collector by following these steps:

1. Edit the configuration file.

2. Change the value of the start_datetime_utc_value to a different one.

3. Save the changes.

4. Restart the collector.

The collector will detect this change and will restart the persistence using the parameters of the configuration file or the default configuration in case it has not been provided.

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.

Collector operations

Verify collector operations

This is for the standalone mode only. You can check the information in the following sections to verify the correct collector operation.

Initialization

The initialization module validates the given configuration and runs the setup, the input (pulling logic), and output (delivering logic) services. A successful run has the following output messages for the initializer module:

Event delivery and Devo ingestion

The event delivery module is in charge of receiving the events from the internal queues where all the 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:

Sender services

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

Sender statistics

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

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
