Provisioning for a Distributed ATM Security Management: The GAMMA Approach
own visualization module that is part of command and control
subsystem.
The SMP receives the following signals/messages:
C

C

C
C

Indication/detection of events from local GAMMA security
systems or other security modules;
Alerts from ATM systems via ATC (air traffic control) systems;

open source software, in order to determine the sentiment and/or
threats related to a particular target. It also allows identifying the
motivation, the characteristics, and the identities of the attackers.
CSIP is based on an open source intelligence service provided by
Leonardo. The CSIP is connected to the command and control subsystem via an API. The main elements of CSIP are listed below:
C

Intelligence scenario configuration;

The disseminated alerts/messages from other SMPs;

C

Crawling of RSS web feed, Twitter, Facebook;

General information about possible attacks from the Internet.

C

Indexing and searching;

C

The SMP produces and sends the following outputs:

Sentiment analysis using natural language processing, or
statistics;

Security reports, to local security systems or to other SMPs;

C

C

API for security reports transmission;

Alarms due for correlation engine;

C

C

e-mail alerting.

C

Recommended countermeasures, to the local security systems or other SMPs;

Specific tools that are available for the operator's use are as follows:

Attack effect prediction reports, to the local security systems
or other SMPs;

C

Alarm clearing, to the other security modules that issued the
alarm.
The following subsections describe the SMP subsystems/modules.

COMMAND AND CONTROL SUBSYSTEM

Searching: semantic search of information system impairments, such as cyber attacks and data breach;
Dashboards: customized dashboards to provide aggregated
views according to the specific analyst's needs;
Case Manager: visual analysis of complex situations;
Reporting: automatic report generation related to either corporate data subtraction or detection of a preplanned attack.

This subsystem provides "alarm correlation," "security monitoring,"
and "decision support" for incident
management. It also includes a "data
collector" for gathering security events
from local security systems and ATC
systems, correlating the alarms/events
using the "correlation engine" and displaying the resulting alarms to the operator using the visualization facility.
The decision support function allows
the operator to provide possible countermeasures to local security systems or
other SMPs. A sanitization function is
also made available in order to modify
sensitive information if required before
transferring it to an information dissemination system (IDS) module.

CYBER SECURITY INTELLIGENCE
PLATFORM
The Cyber Security Intelligence Platform (CSIP) provides GAMMA operators with the possibility to obtain relevant information about possible (cyber)
attacks on ATM systems, crawling the
Internet, and social networks using
