The STOP-IT project has released a number of research results, including tools, technologies, best practice guidelines, reports, materials, and an integrated STOP-IT platform with modular components. You find most of our downloads here or when you click on the boxes below.
The STOP-IT platform
Secure your water infrastructures against cyber-physical attacks and threats with the STOP-IT platform, which supports strategic/tactical planning, real time operational decision making and post-action assessment for the key parts of the water infrastructure. It is:
- scalable (scaling from small utilities to large ones)
- adaptable (including various modules addressing different needs, with expandability for future modules) and
- flexible (the water utility managers can decide how to use it and it will be usable by experts, novices, and even non-technical staff.
The main added value of the platform is that all modules and tools are integrated, connected to each other and interoperable, therefore ensuring the protection against combined cyber-physical threats and allowing the analysis of cascading effects of physical and cyber events. The platform was validated in an operational environment and all solutions were demonstrated in real environments.
The core modules (dark blue) form the backbone while the remaining cyber and physical modules (light blue) offer additional protection or information to critical infrastructure operators.

Risk Analysis and Evaluation Toolkit (RAET)
This is a standalone toolkit. Download the following factsheet for more information:
| Description of the solution | A platform for identifying, analysing and evaluating cyber-physical risks and assorted mitigation actions by providing access to specific tools and models. The Risk Analysis and Evaluation Toolkit links interdisciplinary approaches into a seamless workflow, to synthesize actionable intelligence and support informed decision making in an interactive mode. |
| Challenges addressed | Converging cyber and physical security, assessing cyber-physical threats, and subsequently preparing against them can be a daunting task that requires multidisciplinary approaches and information from multiple sources that span from expert judgment to state-of-art models. There is a need for a system with integrative and modular architecture, that unifies cyber and physical security approaches for contemporary critical infrastructures under a common, flexible, and scalable platform. |
| Innovation | The RAET forms an innovative all-in-one solution that aids risk managers and strategic planners in cyber-wise water utilities. The innovations of the platform lay in each of the components. Thus, the toolkit acts as a wrapper for the nested cyber-physical simulation tools, simplifying and unifying the way the users interact with them. Results can be further explored through embedded components that help utilities to better understand and evaluate the scenario outcomes, based on the organization’s risk criteria. |

Risk Identification Database (RIDB)
This is a standalone tool. Download the following factsheet for more information:
| Description of the solution | The Risk Identification Database is a list of risk events, e.g. examples that assist the users in the Risk Identification step, allowing them to commence the process and draw their attention to some possibilities that should be investigated. Risk events are related to physical and/or cyber threats, which can occur in water distribution systems/water utilities. The Risk Identification Database identifies the type of threat, the sources of risk, the description of the events and the type of consequences produced. |
| Challenges addressed | The tool highlights threat possibilities that should be investigated and their interrelated connections, which indicate that an event might occur. |
| Innovation | This is a new comprehensive database for physical and cyber threats on water distribution systems. |

InfraRisk (CP) application
This is a standalone tool. Download the following factsheet for more information:
| Description of the solution | InfraRisk-CP is a generic risk assessment standalone desktop application devoted to assist in identification and prioritization of cyber-physical threats (CP) attacking the water systems. InfraRisk-CP is independent of any network modelling of systems (EPANET). Having in mind the so-called Bow-Tie visualization of risk, it starts out with a scenario and the undesired main events/threats, which are cyber-physical attacks against assets. The analysis differentiates between these cyber-physical threats, the frequency of main events and possible consequences, and finally, the preventive or protecting barriers. Barriers appear as physical assets or societal critical functions (SCF) in this context. By providing a risk picture presented as different risk matrices, the tool supports decision makers on both, tactical and operational levels in a user-friendly manner. |
| Challenges addressed | Generic risk assessment of cyber-physical threats to water systems. |
| Innovation | Market interest and potential for this tool are high. The tool could be commercially exploited within one year. Innovation readiness and innovation management are scored medium. |

Asset Vulnerability Assessment Tool (AVAT)
This is a standalone tool. Download the following factsheet for more information:
| Description of the solution | The Asset Vulnerability Assessment to Risk Events (AVAT) tool is acting as a procedural „step-by-step“ guide for the assessment of vulnerability of water distribution system assets, taking into consideration the specific characteristics of the assets, the importance of the components for water supply and their „attractiveness“ to be attacked. |
| Challenges addressed | AVAT shows the criticality of each element in the water network, using vulnerability metrics. The tool helps to handle the complexity of water distribution networks, where usually it is not trivial to gain knowledge on the location of the vulnerable components. The tool can score different configurations of the network. |
| Innovation | AVAT allows for quick and simple evaluation of the network vulnerability, which helps the user to focus on the most critical elements, without going through the usual time consuming activities. |

Scenario Planner (SP)
This tool is integrated in the the Risk Analysis and Evaluation Toolkit. Download the following factsheet for more information:
| Description of the solution | The Scenario Planner is an intuitive scenario planning environment to specify multiple-threat scenarios by guiding through available fault trees and mitigation options. It generates model-specific data according to the formulated scenario and passes it to the embedded cyber-physical solvers. |
| Challenges addressed | Simulation models are powerful, yet often difficult tools to work with. The Scenario Planner helps the user to decide which threats to be examined using an intuitive graphical interface. It also enables the user to build scenarios of their interest in order to be examined and simulated within the STOP-IT Stress Testing Platform or any other supported model. |
| Innovation | By employing the Scenario Planner, a higher level of abstraction is provided to the end user, hiding the underlying data files needed by a model to run the simulation. In most cases, the user has to develop the base scenario from scratch only once and then the SP guides them to define attack scenarios, i.e. variations to the base scenario. |

Cyber-physical threats Stress-Testing Platform (STP)
This tool is integrated in the the Risk Analysis and Evaluation Toolkit. Download the following factsheet for more information:
| Description of the solution | A powerful feature of the Risk Analysis and Evaluation Toolkit (RAET) is the Stress Testing Platform (STP), enabling users to run in a batch procedure multiple variations of a given scenario, similarly to a sensitivity analysis approach. In fact, the STP turns all numerical parameters of events comprising a scenario, such as event duration, leakage area or mass of pollutant, into control variables of a stress testing procedure. Users are able to set a value range for each parameter and specify the number of values and the sampling method |
| Challenges addressed | After the identification of a potential cyber-physical threat, risk managers and utility personnel are facing the challenge of estimating the severity of such a situation and the conditions under which the threat would have its greatest impact. This time consuming process includes the execution of multiple scenario simulations, defined by experts, with the inherent risk of missing an important scenario variation. |
| Innovation | The STP will automatically create scenarios having unique combinations of parameter values according to the specifications of the risk manager and will successively execute simulations in a single, seamless stress testing procedure. Managers can control the procedure and view the results as they emerge. |

Key Performance Indicators tool (KPI Tool)
This tool is integrated in the the Risk Analysis and Evaluation Toolkit. Download the following factsheet for more information:
| Description of the solution | The KPI tool is a MATLAB®-based standalone executable, designed to assist in the evaluation process of a threat scenario of cyber and physical attacks. As a whole, the Key Performance Indicator Tool enhances the single scenario assessment, allowing the users to select scenario results and a number of configurations of the system to create a deeper analysis of the simulation results, and identify key information for the tactical and strategic planning. |
| Challenges addressed | The results produced from a simulation process can be huge and/or difficult to interpret. They are usually provided in form of large textiles, documenting the results in detail in the temporal and spatial dimension. There is often a need for supporting graphical and user-friendly tools that would help professionals to easily identify security critical information. The aim of the tool is not to export any ranking or final decision on criticality of a threat, but rather present a user-friendly environment to deploy the STOP-IT Key Performance Indicator Framework in a structured way. |
| Innovation | The main concept behind the KPI tool is a sequential application of user-defined selections as filters to visually present only selected parts of consequence information. The adjustability of the Key Performance Indicators to the company’s risk attitude is the main pillar of the tool development, while additional functionalities were added to assist the risk informed decisions for the threat scenarios examined. All results are presented in a unified way, regardless of the underlying model from which they have been produced. |

Risk Exploration Tool (RET)
This tool needs to be connected with the Risk Identification Database (RIDB), the Risk Analysis and Evaluation Toolkit. and the Risk Reducation Measures Database. Download the following factsheet for more information:
| Description of the solution | The Risk Exploration Tool permits to explore the risks and mitigation actions using the semantic-enriched information, called facets, which allow to homogenise the information under a common vocabulary, and subsequently, provide interoperability between digital systems using a common data format, namely JSON-LD. Considering the risk management domain, one of the main advancements corresponds to the publication of a risks and mitigation actions catalogue to facilitate managers in critical infrastructures to organise the risk management plan. Specifically, the tool offers the possibility to link risks with corresponding risk reduction measures and provides information on the potential implications in case risks would ever be realized. |
| Challenges addressed | Semantic interoperability is the main goal of making information machine-readable by giving them unambiguous, shared meaning. Numerous semantic models exist representing digital and physical systems and linking them with operations accessing the data. However, cyber-physical threats in water infrastructures have not been studied yet in an integrated approach extensively. Therefore, there is a lack of interoperability and data sharing in systems responsible for risk management at the operational, tactical, and planning levels. |
| Innovation | Based on a systematic approach, a representation of concepts, data and entities describing water infrastructures and related cyber-physical threats has been defined, partly by combining and reusing existing ontologies in related fields. The resulting new ontology allows data of cyber and physical threats in water infrastructures to be shared and reused across application, enterprise, and community boundaries without prior knowledge of the data structure, taking advantage of the semantic relation between the defined terms. |

EPANET – EasySketch (EES)
This tool is standalone, available in the the Risk Analysis and Evaluation Toolkit. Download the following factsheet for more information:
| Description of the solution | In case that a water company has no pipeline network model, the Epanet – EasySketch (EES) tool is used to generate an EPANET input file starting from a simplified sketch of the system without use of the EPANET software. |
| Challenges addressed | The access to the modelling platform of STOP-IT and the use of the tools of this platform is only possible for water companies, who already have a model of the pipeline network. To overcome this requirement and in case that a water company has no pipeline network model, the Epanet – EasySketch (EES) tool can be used. |
| Innovation | The tool may be used when (a) calculations based on an EPANET model are performed, (b) a calibrated hydraulic network model is not available, (c) the typical setup of a hydraulic model is too sophisticated for the desired results, (d) the water supply company has not the skilled and trained staff, and (e) rough estimations are sufficient. |

They allow to centralise the access requests, automating the process of granting access to specific areas within the same site, as well as to give access for limited time. Authorized users receive an electronic key and an access-control mobile app. Access points are equipped with stand-alone smart electronic locks. These locks communicate with the authentication and back-end servers via the authorized user‘s mobile application. The system needs the location of the site, maps and the information on the workers in the site that will need access privileges. All the data can be controlled easily from the management system. |
| Challenges addressed | With the help of the system it is possible to track entry of authorized users or enable or disable remote privileges for opening and locking doors. It does not require the implementation of wired or wireless infrastructure and therefore reduces maintenance costs. It increases the safety, is user friendly and flexible, offers navigation to facilities and works with a standalone system, among other things. |

MODULE 7 - Tool for alerting users/citizens about a critical situation
Module 7 incudes 1 tool, the Public Warning Notification System (PWNS)
Public Warning Notification System (PWNS)
This is a standalone tool. Download the following factsheet for more information:
| Description of the solution | The STOP-IT Public Warning Notification System detects incidents and informs users and citizens by sending information and instructions to follow. The PWNS has two main functionalities: detect and report incidents, and inform users and citizens. It is a key element in the solution developed by the STOP-IT project as it activates the first phase of the system, triggering an alert that will ultimately put in place the corresponding response plan. |
| Challenges addressed | Water agencies, regulators, municipalities and environmental agencies can benefit from the Public Warning Notification System. The tool is also useful for any industrial operator who needs to monitor processes and can integrate data sources or deploy sensors to capture data variables. Such data can be processed to generate alerts when specific conditions, like threshold limits, absolute/relative variations or other rules upon request from the operator, are met. Response plans and lists of action to be taken when a specific situation is presented can be defined individually to enable the operator to implement the appropriate actions. |
| Innovation | The PWNS processes data, alerts and detected incidents from external sources and reports them to the STOP-IT core platform. At this initial stage the incident has to be validated by a human operator. Once this is done, the anomaly is notified to the system that, by cross-checking with other incident-related data from different sources, can identify the risk situation. This assessment will be sent to the visualisation interface for water utilities. The visualisation interface starts a response plan with actions to be executed when specific situations arise. These actions are based on different parameters set by water operators and can include both, corrective and mitigation measures. The system also sends the information and instructions to follow to the users and citizens using the most appropriate channels, i.e. email, SMS, mobile app notifications, etc. |

MODULE 8 - Tools for risk exposure assessment, alert generation and countermeasure proposition
Module 8 includes 2 tools:
Reasoning Engine (REN)
Fault Tree Editor (FTE)
Reasoning Engine (REN)
This tool needs to be connected to the Real-time Anomaly Detector (RTAD). Download the following factsheet for more information:
| Description of the solution | The reasoning engine generates real-time alerts and proposes mitigation actions. It allows the configuration of rules for processing detections (referring to cyber and physical level) and generates high-level alerts by using Complex Event Processing (CEP). Subsequently, it provides mitigation actions to be taken and extra information that facilitates the operators. The Reasoning Engine acts as a mediator between event sources and the system operator and is the means to filter, aggregate, correlate and upscale information in an endless stream of input data. |
| Challenges addressed | With real-time alerting and mitigation proposition, the tool supports the decision-making process in water utilities. Based on the Reasoning Engine’s reactive and asynchronous reasoning principle, it detects patterns in an endless stream of input data, allowing the selection of important information. The operator on duty is facilitated and can be less experienced/trained, compared to traditional practice. Regarding the mitigation of incidents, the tool, in compliance with the MITRE ATT&CK framework, includes tactics and techniques to the advice on how to mitigate the received events to speed up investigations and responses. The tool also supports batch-processing, vital for post-evaluation and further enhancement of the processing results. |
| Innovation | The tool allows configurable processing per water utility that involves cyber and physical events as it integrates with the rest of the tools in the STOP-IT platform. |

Configuration of a processing rule
Fault tree editing
Fault Tree Editor
This is a standalone tool. Download the following factsheet for more information:
| Description of the solution | The solution assesses the risk exposure of a water utility with the creation and calculation of Fault Trees. A Fault Tree is a systematic and deductive method for defining a single undesirable event and determining all possible reasons that could cause that event to occur. It can be applied to analyse the combined effects of simultaneous failures on the undesired (top) event, to evaluate system reliability, to identify potential design defects and safety hazards, to simplify maintenance and troubleshooting and finally it can also be used to evaluate potential corrective actions or the impact of design changes. |
| Challenges addressed | Addressed is the need of water utilities for tactical and strategic decisions and planning. In particular, the methodology provides all the tools needed to represent, quantify and understand the risks involved in the utility. Moreover, it provides a reliable basis for determining safety countermeasures, in order to predict, prevent or mitigate accidents. |
| Innovation | The implemented methodology is quite flexible and can analyse the consequences caused by some units and special reasons resulting in accidents, such as human factors and environmental factors. A treatment of Common Cause failures and a subset of the general set of dependent events having a significant contribution on the safety of technical systems are implemented in the method. |

MODULE 9 - Tool that visualises information in the STOP-IT platform from all modules
Module 9 includes 1 tool, the Enhanced Visualisation Interface for the water utilities (EVI)
Factsheet: Enhanced Visualisation Interface for the water utilities (EVI)
Enhanced Visualisation Interface for the water utilities (EVI)
This tool needs to be connected to at least one of the following tools: Reasoning Engine (REN), Real-time
Anomaly Detector (RTAD), Computer Vision Tool (CVT) and/or the Public Warning Notification System (PWNS). Download the following factsheet for more information:
Factsheet: Enhanced Visualisation Interface for the water utilities (EVI)
| Description of the solution | Purpose of the Enhanced Visualization Interface is to share operational information for the understanding of the current situation in a water utility. It is a web user interface that enhances situational awareness by creating a common operational picture. The module leverages real-time, historical and GIS mapping data, incident information and shared information and displays them in multiple-perspective views. The information can be simultaneously shared among operators and decisionmakers during all phases of risk management, detection, processing, analysis and mitigation, allowing collaboration for cyber and physical incidents. |
| Challenges addressed | Operators and decision makers can simultaneously view data from multiple sources to understand the current situation in a water utility and act effectively. To avoid overloading users with information, the interface is organised in multiple views. The module is scalable from small utilities to large ones with multiple water distribution networks, it can be expanded to consume information from other external modules and it is flexible, allowing water utility managers to decide its use by experts or non-technical staff. |
| Innovation | The solution brings together the cyber and physical worlds and all phases of risk management: From the detection, processing and analysis to the corresponding mitigation. |

The STOP-IT platform.
The STOP-IT platform can be connected to all other tools and modules. Download the following factsheet for more information:
Factsheet about the STOP-IT platform
| Description of the solution | Secure your water infrastructures against cyber-physical attacks and threats with the STOP-IT platform, which supports strategic/tactical planning, real time operational decision making and post-action assessment for the key parts of the water infrastructure. The STOP-IT platform is the combination of all STOP-IT tools in an integral, scalable, adaptable, flexible and modular solution. The main added value of the platform is that all modules and tools are integrated, connected to each other and interoperable, therefore ensuring the protection against combined cyber-physical threats and allowing the analysis of cascading effects of physical and cyber events. The platform was validated in an operational environment and all solutions were demonstrated in real environments. |
| Challenges addressed | STOP-IT solutions through their combination will help water utilities operators identify and detect risks, enhance their analysis capabilities as well as their preparedness and response. |
| Innovation | The STOP-IT platform introduces a novel integrated approach for the security of water critical infrastructures that combines cyber and physical protection modules in an overarching solution. |

STOP-IT Modular components and Dataflow
The connection of the STOP-IT platform modules and tools
The Interoperable Water Middleware (which is an additional tool integrating all STOP-IT tools) is standalone but can be connected to all other tools and modules. Download the following factsheet for more information:
| Description of the solution | The STOP-IT interoperable water middleware is a web-based tool to access the information of the critical infrastructure and expose that information using a common data exchange model. Therefore, the interoperable water middleware corresponds to a context-broker model that follows the standards of NGSI-LD (compatibility with FIWARE) and also, with the Web of Things architecture (W3C standards). The combination of both systems enables STOP-IT to elaborate several “plugins” (COAP; MQT; REST) to interact with the different systems and uplift the information using the common vocabulary. |
| Challenges addressed | Commonly in the water infrastructure, there are different informational “siloes” that fragmented the sector. Moreover, the lack of data exchange models combined with the adoption of different standards caused a limited decision-making. For that, there is a need for digital tools that enable information interrelationships to share knowledge inside the water infrastructures. This aspect will enable new strategies to detect critical events. |
| Innovation | Based on the challenges exposed in the previous point, the main innovations performed with the middleware can be summarised into the elaboration of common data exchange model based on current standards (ontology) to represent and model risk and mitigation actions. Moreover, the adoption of open-standards such as NGSI and WoT enable to be compatible with FIWARE and WoT reference architectures. Thus, it will be an open framework compatible with EU and international digital architectures for integrating massive amount of data. |
