COMMAND LINE USAGE

In order to use the CLI, you need credentials in MVEDR. The CLI has several parameters (as described with mvision-edr-activity-feed -h):

::

usage: mvision-edr-activity-feed  [-h] [--version] --url URL --username
                                  USERNAME --password PASSWORD --module MODULE
                                  [--wait WAIT]
                                  [--loglevel {critical,error,warning,info,debug,notset}]
                                  [--logfile LOGFILE] [--reset]
                                  [--consumer-group CONSUMER_GROUP]

  --url URL             Base URL for MVISION EDR (default: None)
  --username USERNAME   Username for the service (default: None)
  --password PASSWORD   Password for the service (default: None)
  --module MODULE       Module to register events (default: None)
  --wait WAIT           Time to wait between queries (default: 5)
  --loglevel {critical,error,warning,info,debug,notset}

  --topic TOPIC         Topic to subscribe to (default: ['case-mgmt-events',
                        'BusinessEvents', 'threatEvents'])
  --reset               Starts the consumer group from the earliest event
                        available. This only works when initializing the
                        consumer group the first time (default: False)
  --consumer-group CONSUMER_GROUP
                        Name for the consumer group to use (default:
                        mcafee_investigator_events)
  --config CONFIG       Configuration key/value pairs for callbacks (default:
                        None)

SUBSCRIPTIONS

You need to provide at least one module with your subscriptions for the CLI to load. The following is an sample subscription:

.. code:: python

import logging
from mvision_edr_activity_feed import subscribe


@subscribe(entity='case', subtype='creation')
def case_created(event):
    logging.info("CASE CREATED: %s", event)


@subscribe(entity='case', subtype='priority-update')
def case_updated(event):
    logging.info("CASE PRIORITY UPDATED: %s", event)


@subscribe(entity='case', subtype='status-update')
def case_status_updated(event):
    logging.info("CASE STATUS UPDATED: %s", event)


@subscribe("user == 'some_user'")
def custom_subscription(event):
    logging.info("EVENT FOR USER 'some_user': %s", event)

In the first three examples, we are subscribing to the following events: Case creation, Case priority updates, and Case status updates. On the last example we are subscribing to events that have a property user with a value of some_user (as defined by the corresponding JMESPath <http://jmespath.org/>_ expression)

Note that there are two ways to subscribe to events:

• Basic: This is for events that follow out Event Specification <EVENT_SPEC.rst>__

  • entity: The entity affected by the event.
  • subtype: The event subtype, related to the entity.

• Advanced: This is for generic events, and uses a JMESPath <http://jmespath.org/>_ expression to determine the subscription

CONFIGURE RSYSLOG IN CASE OF REMOTE LOGGING

In case of using rsyslog for remote logging please follow the documentation explained here: https://www.tecmint.com/setup-rsyslog-client-to-send-logs-to-rsyslog-server-in-centos-7/

rsyslog.conf that can be used as an example: https://github.com/mcafee/mvision-edr-activity-feed/blob/develop/rsyslog.conf

PARSING RULE IN CASE OF SIEM

In case of a SIEM of type ESM, it's recommended to import the following parsing rule to ASP General Parser in order to see the event categorized as MVDER Suspicious Activity (Displayed in Events View with proper details instead of Unknown event): https://github.com/mcafee/mvision-edr-activity-feed/blob/develop/RULE_MVISION_EDR_THREAT.xml

RUNNING THE EXAMPLES

There are a couple of simple examples that will log event information to the console. These are executed as follows:

.. code:: shell

mvision-edr-activity-feed --url https://api-int-cop.soc.mcafee.com/ --username YOUR_USERNAME --password YOUR_PASSWORD --module samples.generic --loglevel=debug

.. code:: shell

mvision-edr-activity-feed --url https://api-int-cop.soc.mcafee.com/ --username YOUR_USERNAME --password YOUR_PASSWORD --module samples.individual --loglevel=debug

You can also mix several modules in a single call:

.. code:: shell

mvision-edr-activity-feed --url https://api-int-cop.soc.mcafee.com/ --username YOUR_USERNAME --password YOUR_PASSWORD --module samples.generic --module samples.individual --loglevel=debug
