Article
As we come to the end of the book, we look at the end-goals of achieving CSA. In this chapter we explain that the ultimate objective of CSA is to enable situation management, i.e., continuous adjustments of both the network and the mission that the network supports, in order to ensure that the mission continues to achieve its objectives. Indeed, se...
Patent
Method and apparatus for situation-based management of natural and artificial systems using event correlation and a situation manager. Input is provided from multiple sources in the form of a collection of events. A first level of processing performs event correlation over the collection of events and infers new events and new qualities of events....
Conference Paper
One of the inherit features of cognitive situation awareness and decision support processes is that they are context-dependent. This is hardly disputed by anybody, but as soon one wants to understand what this context dependency means, or even more, what is context and how it relates to a situation then we have to admit that no common understanding...
Conference Paper
While there is an extensive body of research available in understanding the spatiotemporal eventualities of reality, we still face noticeable confusion in conceptualization of such basic notions like states, events, and actions. This is becoming increasingly evident when one has to deal with dynamic systems, especially systems that are subject of i...
Article
The overall goal of the processes of cyber attack impact assessment that was discussed in our earlier works was strictly to increase the cyber security situation awareness. In this paper we will move further, from the cyber security situation assessment task to the task of achieving of missions that are tolerant to the cyber attacks committed again...
Conference Paper
Cyber attacks committed against networks and software assets (operating systems, applications, and data repositories) have profound impact both on ongoing and future missions that use IT services offered by the networks. The attacks by exploiting the vulnerabilities of the software assets can push their impact through the cyber terrain - the cyber...
Article
The paper proposes a conceptual framework and a method for assessing impact that cyber attacks might have to cyber assets, services, and missions. The paper describes the model of a cyber attack based on an extended conceptual graph. It introduces the notion of a cyber-terrain as a multi- level information structure containing assets and services,...
Article
Large scale situation management applications such as disaster recovery and network-centric battle management are characterized by distributed heterogeneous agent platforms with dynamic agent populations, highly variable network connectivity and bandwidth, and localized situation knowledge and event collection. We describe a new agent model and an...
Article
Many domains, such as physical infrastructure and cyber security monitoring, battlefield operations management, disaster response and crisis management, and homeland security, are characterized by dense realtime sensing, large numbers of distributed heterogeneous information sources, and a variety of distributed, communicating, and network-enabled...
Article
Spatio-temporal reasoning plays a significant role in situation management that is performed by intelligent agents (human or machine) by affecting how the situations are recognized, interpreted, acted upon or predicted. Many definitions and formalisms for the notion of spatio-temporal reasoning have emerged in various research fields including psyc...
Article
In this article we discuss the problem of inferring threats in an urban environment, where the knowledge of the environment involves multiple types of intelligence and infrastructure data, and is by nature uncertain or approximate. We use a collection of situation-aware agents to infer potential threats in such environments, where agents are respon...
Article
Context plays a significant role in situation resolution by intelligent agents (human or machine) by affecting how the situations are recognized, interpreted, acted upon or predicted. Many definitions and formalisms for the notion of context have emerged in various research fields including psychology, economics and computer science (computational...

Application areas include the understanding and awareness of complex unfolding scenarios such as homeland security threats and future battlespace engagements. The paper (i) discusses the differences between the environments/requirements for event-based management and situation mana...
Conference Paper
In the paper we focus on (i) an assessment of impact on missions or business processes resulting from cyber attacks and (ii) the subsequent projection of further possible attacks and corresponding impact assessments. A reference model for impact assessment and situation projection (IASP) is provided, based on which we propose a constraint satisfact...
Conference Paper
Full-text available
This paper describes a novel approach for managing service-centric communications networks called distributed autonomic management (DAM). Current approaches to network management employ the client/server model, cooperative stationary agents, and/or non-intelligent mobile agents. The DAM model consists of communities of mobile and stationary intelli...
Article
Forces engaged in tactical urban combat operations require a continuous and comprehensive picture of the combat environment to quickly detect the target and effectively reduce opposition. This requires a significant coordination of actions, situational awareness, and fast decision-making. This paper focuses on modeling the collaboration acts among...
Article
The response, rescue and recovery teams that are engaged in disaster management operations require a continuous and comprehensive information flow of the disaster environment and a situational awareness in order to undertake fast and coordinated actions. Because of highly dynamic and often unpredictable disaster situations the teams need to adjust...
Article
We discuss the problem of making sense of very large amounts of multi-sensor data in terms of information fusion and situation awareness. Our focus is on the application layer of the GIG in support of ISR analysis, sometimes referred to as level 2 fusion or cognitive fusion. We discuss an approach where the key ontological constructs are events, ev...
Conference Paper
Previous work in automating insider threat detection has included top-down analysis and fusion of events from network and system monitors. Situation-awareness can extend the capability of such techniques to include observables outside of cyber-space. The application of situation-management to insider threats is becoming more practical due to the gr...
Article
When event correlation was first used in integrated management, in the early 1980s, several techniques devised by the artificial intelligence and database communities were applied to network element management for analyzing alarms sent by expensive, self-monitoring telephone switches. Today, it is used for detecting faults in wireless networks, for...

Article
It is important for situation management systems to represent the state of the sensing infrastructure in a systematic way. The state and extent of the sensing infrastructure varies over time due to planned improvements, intentional attacks, as a side effect of a disaster, or due to deployment of mobile sensing equipment. In this paper we describe h...
Article
We extend the BDI (Belief, Desire, Intention) agent model by enabling agent beliefs to be based on real-time situations that are generated by a situation management (SM) system. This has several advantages for multi-agent systems using BDI agents. First, because of the use of event correlation and data fusion techniques in situation management, age...
Conference Paper
This paper proposes a new model of situation management in distributed dynamic systems, such as telecommunication networks, modern battlespaces, and disaster relief operations. The proposed model is based a multi-agent systems approach, where the Belief-Desire-Intension agent architecture has been expanded by an advanced interpretation cycle. The c...
Article
Full-text available
Natural and human-made disasters create unparalleled challenges to Disaster Situation Management (DSM). One of the major weaknesses of the current DSM solutions is the lack of comprehensive understanding of the overall disaster operational situation, and very often making decisions based on a single event. Such weakness is clearly exhibited by the...

We describe the integration of two technologies to achieve cognitive fusion--the dynamic analysis of data combined from multiple sources in order to recognize complex dynamic situation patterns, construct models or hypotheses of unfolding situations, and take action in response to situations. The two technologies are temporal event correlation and...
Conference Paper
According to modern USA defense doctrine, the future war will involve high mobility and operational tempo, a convergence of real and cyber battlespace, dependence on huge volumes of data from multiple heterogeneous sources, unpredictable enemy actions, and poorly defined borders of the operational theatre. As a consequence of these new characterist...
