RSA SecurID

Overview

SecurID is a token system, or authenticator, produced by RSA Security and intended to offer strong authentication to its user in the context of access to an information system.

The following Sekoia.io built-in rules match the intake RSA SecurID. This documentation is updated automatically and is based solely on the fields used by the intake which are checked against our rules. This means that some rules will be listed but might not be relevant with the intake.

Extracted Fields

The following table lists the fields that are extracted, normalized under the ECS format, analyzed and indexed by the parser. It should be noted that infered fields are not listed.

Name Type Description
agent.id keyword Unique identifier of this agent.
agent.name keyword Custom name of the agent.
destination.ip ip IP address of the destination.
event.code keyword Identification code for this event.
event.reason keyword Reason why this event happened, according to the source
log.level keyword Log level of the log event.
observer.hostname keyword Hostname of the observer.
observer.serial_number keyword Observer serial number.
process.command_line wildcard Full command line that started the process.
process.working_directory keyword The working directory of the process.
rsa.securid.action.name keywords represents the name of the action taken in an RSA SecureID event, such as 'authenticate' or 'access denied'. It is also a keyword field and can be used to search for events based on the specific action taken.
rsa.securid.agent.domain.id keywords This field is similar to rsa.secureid.domain.id, but it specifically represents the domain or realm associated with the agent (such as a server or application) that generated the SecureID event.
rsa.securid.agent.ip keywords This field represents the IP address of the agent (server or application) that generated the SecureID event.
rsa.securid.class keywords represents the class or category of an RSA SecureID event. It is a keyword field, which means it can be used to group and filter events based on the SecureID class they belong to.
rsa.securid.domain.id keywords represents the unique ID of the domain or realm associated with a SecureID event.
rsa.securid.event.outcome keywords The outcome of the event
rsa.securid.objects.id keywords represents the unique ID of the object associated with a SecureID event.
rsa.securid.objects.name keywords represents the name of the object associated with a SecureID event.
rsa.securid.objects.security.id keywords represents the unique ID of the security context associated with the object in a SecureID event.
rsa.securid.objects.source.id keywords represents the unique ID of the source device or system associated with the object in a SecureID event.
rsa.securid.objects.type keywords represents the type of object (such as user, group, or resource) associated with a SecureID event.
rsa.securid.policy.expression keywords represents the expression used in the policy associated with a SecureID event.
rsa.securid.policy.id keywords represents the unique ID of the policy associated with a SecureID event.
rsa.securid.policy.method.id keywords represents the unique ID of the policy method used in a SecureID event. It can be used to track and analyze policy enforcement activity.
rsa.securid.policy.method.name keywords represents the name of the policy method used in a SecureID event.
rsa.securid.process.tty keywords This field likely represents the terminal or tty associated with the SecurID authentication process being logged.
rsa.securid.session.id keywords represents the unique ID of a SecureID session. It can be used to track and analyze user activity over multiple SecureID events.
rsa.securid.source.id keywords represents the unique ID of the source device or system that generated the SecureID event.
rsa.securid.user.firstname keywords This field likely represents the first name of the user associated with the SecurID authentication request being logged.
rsa.securid.user.lastname keywords This field likely represents the last name of the user associated with the SecurID authentication request being logged
source.ip ip IP address of the source.
user.id keyword Unique identifier of the user.
user.name keyword Short name or login of the user.
user.target.name keyword Short name or login of the user.

Configure

Prerequisites

An internal log concentrator is required to collect and forward events to Sekoia.io.

Enable Syslog forwarding

In the Security Console of the RSA Authentication Manager:

  1. On the upper bar, go to Setup and select System Settings.
  2. Under Basic Settings, click on Logging.
  3. Select Primary as the selected instance and click Next
  4. In the section Log levels, choose the level for each type.
  5. In the section Log Data Retention, for each log data, select Save to internal database and remote Syslog at the following hostname or IP address, then type the location of the log concentration.
  6. Click Save

Create the intake

Go to the intake page and create a new intake from the format RSA SecurID.

Forward logs to Sekoia.io

Please consult the Syslog Forwarding documentation to forward these logs to Sekoia.io.
