Log Management Security

This article is part of a series on data security.

The Log Management product supports multiple environments and formats, allowing customers the flexibility to submit to Datadog nearly any data they choose. This article describes the main security guarantees and filtering controls available to users when submitting logs to Datadog.

Information Security

The Datadog Agent submits logs to Datadog over a TLS-encrypted TCP connection, requiring an outbound communication over port 10516. The Datadog Agent can also be configured to send logs over secured HTTPS requests, requiring an outbound communication over port 443. Datadog uses symmetric encryption at rest (AES-256) for indexed logs. Indexed logs are deleted from the Datadog platform once their retention period, as defined by the customer, expires.

Logs Filtering

For customers using release 6, the Agent can be configured to filter logs sent by the Agent to the Datadog application. To prevent the submission of specific logs, use the log_processing_rules setting, with the exclude_at_match or include_at_match type. This setting enables the creation of a list containing one or more regular expressions, which instructs the Agent to filter out logs based on a whitelist or blacklist.

Logs Obfuscation

For customers using release 6, the Agent can be configured to obfuscate specific patterns within logs sent by the Agent to the Datadog application. To mask sensitive sequences within your logs, use the log_processing_rules setting, with the mask_sequences type. This setting enables the creation of a list containing one or more regular expressions, which instructs the Agent to redact sensitive data within your logs.

Configuration Requirements for HIPAA-enabled Customers

Datadog will sign a Business Associate Agreement (BAA) with customers that transmit protected health information (ePHI) via Datadog’s Log Management Service.

Prior to executing a BAA, customers transmitting ePHI to the Datadog Log Management Service must implement the following configurations:

• The Datadog Agent must be configured to submit logs to tcp-encrypted-intake.logs.datadoghq.com
• The Datadog log collection AWS Lambda function must be configured to submit logs to lambda-tcp-encrypted-intake.logs.datadoghq.com by setting the DD_URL environment variable as well as setting DD_USE_TCP to true
• The GCP push forwarder must be configured to submit logs to gcp-encrypted-intake.logs.datadoghq.com
• Other log sources besides the Datadog Agent must be configured to submit logs to http-encrypted-intake.logs.datadoghq.com

The following sample configuration can be used with the Datadog Agent to submit logs to a HIPAA-ready endpoint directly (i.e. without a proxy):

logs_enabled: true
logs_config:
  logs_dd_url: tcp-encrypted-intake.logs.datadoghq.com:10516
  logs_no_ssl: false

With the Docker Agent, pass in DD_LOGS_CONFIG_LOGS_DD_URL=tcp-encrypted-intake.logs.datadoghq.com:10516 as an environment variable.

Additionally, certain features are not available at the moment to customers who have signed Datadog’s BAA, notably:

• Users cannot request support via chat
• Rehydration from Log Archives is disabled
• Generation of metrics from logs is disabled
• Notifications from Log Monitors cannot include log samples
• Log Monitors cannot be configured with a group-by clause
• You cannot share logs (nor traces) from the explorer through web integrations.

If you have any questions about how the Log Management Service satisfies the applicable requirements under HIPAA, please contact your account manager.
