Thanks for sharing your feedback!

senhasegura collects information and events from the environment to monitor various product metrics, including table identifiers and the status of running robots. This data can be sent to SIEM solutions for monitoring.

SIEM solutions provide a comprehensive view for Information Security administrators, allowing them to monitor activities in the IT environment through log data. SIEM uses these records to identify, categorize, and analyze incidents and events, generating security reports that cover suspicious or malicious activities.

Additionally, SIEM can send alerts through different channels such as SMS, instant messaging, email, and ticket opening if it detects potential security threats based on established configuration rules.

Alerts sent by senhasegura include:

User authentication on the device.
Remote login on the device.
Failures in the senhasegura server.
Password expiration.

senhasegura is compatible with the most used SIEM tools on the market and offers support for sending messages in the following formats:

CEF
Syslog (RFC 5424)
Sensage

CEF messages

CEF is a message format created to standardize the sending of information to SIEM and follows the order CEF:0|MT4|senhasegura|3.27.0-4|336.501|UPDATE INCIDENT|9|Extensions.

Item	Description
Version	The version of the CEF format. In the example above, we used '0'.
Vendor	The name of the company responsible for the product. In the example above, we used 'MT4'.
Product	The name of the product generating the event. In the example above, we used 'senhasegura'.
Product version	The product version. In the example above, we used '3.27.0-4'.
Event ID	The ID of the event that occurred. Each ID is unique to identify the event. In the example above, we used '336501'.
Event name	The type of event that occurred. In the example above, we used 'Update Incident' to indicate that an update incident has occurred.
Severity	The severity of the event that occurred. The sequence goes from 1 to 10. The higher the number, the more serious the incident.

Furthermore, the system presents a list of extensions that provide detailed information about the event.

RFC 5424 messages

senhasegura also supports syslog files that follow the RFC 5424 standard. The header of this message format contains the following fields:

priority: according to event type
facility: 1 (user)
App: senhasegura
procid: PID of the current process
message: event message

Supported messages

These are some of the message formats that are native to senhasegura and can be exported to an external SIEM solution:
