SoK: Contemporary Issues and Challenges to Enable Cyber Situational Awareness for Network Security

Cyber situational awareness is an essential part of cyber defense that allows the cybersecurity operators to cope with the complexity of today's networks and threat landscape. Perceiving and comprehending the situation allow the operator to project upcoming events and make strategic decisions. In this paper, we recapitulate the fundamentals of cyber situational awareness and highlight its unique characteristics in comparison to generic situational awareness known from other fields. Subsequently, we provide an overview of existing research and trends in publishing on the topic, introduce front research groups, and highlight the impact of cyber situational awareness research. Further, we propose an updated taxonomy and enumeration of the components used for achieving cyber situational awareness. The updated taxonomy conforms to the widely-accepted three-level definition of cyber situational awareness and newly includes the projection level. Finally, we identify and discuss contemporary research and operational challenges, such as the need to cope with rising volume, velocity, and variety of cybersecurity data and the need to provide cybersecurity operators with the right data at the right time and increase their value through visualization

Developing Network Situational Awareness through Visualization of Fused Intrusion Detection System Alerts

With networks increasing in physical size, bandwidth, traffic volume, and malicious activity, network analysts are experiencing greater difficulty in developing network situational awareness. Traditionally, network analysts have used Intrusion Detection Systems to gain awareness but this method is outdated when analysts are unable to process the alerts at the rate they are being generated. Analysts are unwittingly placing the computer assets they are charged to protect at risk when they are unable to detect these network attacks. This research effort examines the theory, application, and results of using visualizations of fused alert data to develop network situational awareness. The fused alerts offer analysts fewer false-positives, less redundancy and alert quantity due to the pre-processing. Visualization offers the analyst quicker visual processing and potential pattern recognition. This research utilized the Visual Information Management toolkit created by Stanfield Systems Inc. to generate meaningful visualizations of the fused alert data. The fused alert data was combined with other network data such as IP address information, network topology and network traffic in the form of tcpdump data. The process of building Situational Awareness is an active process between the toolkit and the analyst. The analyst loads the necessary data into the visualization(s), he or she configures the visualization properties and filters the visualization(s). Results from generating visualizations of the network attack scenarios were positive. The analyst gained more awareness through the process of defining visualization properties. The analyst was able to filter the network data sources effectively to focus on the important alerts. Ultimately, the analyst was able to follow the attacker through the entry point in the network to the victims. The analyst was able to determine that the victims were compromised by the attacker. The analyst wasn\u27t able to definitively label the attack specifically yet the analyst was able to follow the attack effectively leading to Situational Awareness

Kinetic and Cyber

We compare and contrast situation awareness in cyber warfare and in conventional, kinetic warfare. Situation awareness (SA) has a far longer history of study and applications in such areas as control of complex enterprises and in conventional warfare, than in cyber warfare. Far more is known about the SA in conventional military conflicts, or adversarial engagements, than in cyber ones. By exploring what is known about SA in conventional, also commonly referred to as kinetic, battles, we may gain insights and research directions relevant to cyber conflicts. We discuss the nature of SA in conventional (often called kinetic) conflict, review what is known about this kinetic SA (KSA), and then offer a comparison with what is currently understood regarding the cyber SA (CSA). We find that challenges and opportunities of KSA and CSA are similar or at least parallel in several important ways. With respect to similarities, in both kinetic and cyber worlds, SA strongly impacts the outcome of the mission. Also similarly, cognitive biases are found in both KSA and CSA. As an example of differences, KSA often relies on commonly accepted, widely used organizing representation - map of the physical terrain of the battlefield. No such common representation has emerged in CSA, yet.Comment: A version of this paper appeared as a book chapter in Cyber Defense and Situational Awareness, Springer, 2014.

Predictions of Network Attacks in Collaborative Environment

This paper is a digest of the thesis on predicting cyber attacks in a collaborative environment. While previous works mostly focused on predicting attacks as seen from a single observation point, we proposed taking advantage of collaboration and exchange of intrusion detection alerts among organizations and networks. Thus, we can observe the cyber attack on a large scale and predict the next action of an adversary and its target. The thesis follows the three levels of cyber situational awareness: perception, comprehension, and projection. In the perception phase, we discuss the improvements of intrusion detection systems that allow for sharing intrusion detection alerts and their correlation. In the comprehension phase, we employed data mining to discover frequent attack patterns. In the projection phase, we present the analytical framework for the predictive analysis of the alerts backed by data mining and contemporary data processing approaches. The results are shown from experimental evaluation in the security alert sharing platform SABU, where real-world alerts from Czech academic and commercial networks are shared. The thesis is accompanied by the implementation of the analytical framework and a dataset that provides a baseline for future work

Cyber Situational Awareness and Cyber Curiosity Taxonomy for Understanding Susceptibility of Social Engineering Attacks in the Maritime Industry

The maritime information system (IS) user has to be prepared to deal with a potential safety and environmental risk that can be caused by an unanticipated failure to a cyber system used onboard a vessel. A hacker leveraging a maritime IS user’s Cyber Curiosity can lead to a successful cyber-attack by enticing a user to click on a malicious Web link sent through an email and/or posted on a social media website. At worst, a successful cyber-attack can impact the integrity of a ship’s cyber systems potentially causing disruption or human harm. A lack of awareness of social engineering attacks can increase the susceptibility of a successful cyber-attack against any organization. A combination of limited cyber situational awareness (SA) of social engineering attacks used against IS users and the user’s natural curiosity create significant threats to organizations. The theoretical framework for this research study consists of four interrelated constructs and theories: social engineering, Cyber Curiosity, Cyber Situational Awareness, and activity theory. This study focused its investigation on two constructs, Cyber Situational Awareness and Cyber Curiosity. These constructs reflect user behavior and decision-making associated with being a victim of a social engineering cyber-attack. This study designed an interactive Web-based experiment to measure an IS user’s Cyber Situational Awareness and Cyber Curiosity to further understand the relationship between these two constructs in the context of cyber risk to organizations. The quantitative and qualitative data analysis from the experiment consisting of 174 IS users (120 maritime & 54 shoreside) were used to empirically assess if there are any significant differences in the maritime IS user’s level of Cyber SA, Cyber Curiosity, and position in the developed Cyber Risk taxonomy when controlled for demographic indicators. To ensure validity and reliability of the proposed measures and the experimental procedures, a panel of nine subject matter experts (SMEs) reviewed the proposed measures/scores of Cyber SA and Cyber Curiosity. The SMEs’ responses were incorporated into the proposed measures and scores including the Web-based experiment. Furthermore, a pilot test was conducted of the Web-based experiment to assess measures of Cyber SA and Cyber Curiosity. This research validated that the developed Cyber Risk taxonomy could be used to assess the susceptibility of an IS user being a victim of a social engineering attack. Identifying a possible link in how both Cyber SA and Cyber Curiosity can help predict the susceptibility of a social engineering attack can be beneficial to the IS research community. In addition, potentially reducing the likelihood of an IS user being a victim of a cyber-attack by identifying factors that improve Cyber SA can reduce risks to organizations. The discussions and implications for future research opportunities are provided to aid the maritime cybersecurity research and practice communities

System for Continuous Collection of Contextual Information for Network Security Management and Incident Handling

In this paper, we describe a system for the continuous collection of data for the needs of network security management. When a cybersecurity incident occurs in the network, the contextual information on the involved assets facilitates estimating the severity and impact of the incident and selecting an appropriate incident response. We propose a system based on the combination of active and passive network measurements and the correlation of the data with third-party systems. The system enumerates devices and services in the network and their vulnerabilities via fingerprinting of operating systems and applications. Further, the system pairs the hosts in the network with contacts on responsible administrators and highlights critical infrastructure and its dependencies. The system concentrates all the information required for common incident handling procedures and aims to speed up incident response, reduce the time spent on the manual investigation, and prevent errors caused by negligence or lack of information

Conception d’un tableau de bord stratégique en sécurité de l’information pour le soutien de la conscience de la situation

Le responsable de la sécurité des systèmes d’information (CISO) a pour objectif de s’assurer que le conseil d'administration et les hauts dirigeants ont une bonne compréhension de la situation actuelle de l'organisation en matière de sécurité de l'information, puis d’agir de conseiller stratégique pour les décisions qui ont un impact sur la sécurité de l’information. Pour atteindre ces objectifs, le CISO doit avoir accès à de l’information fiable et complète, au moment opportun. Comme la reddition stratégique d’une telle quantité d’information est un processus complexe, elle nécessite l’utilisation d’outils comme le tableau de bord de gestion, défini comme étant un résumé en une page de l’information critique qui permet à l’utilisateur d'atteindre ses objectifs. Cet article propose une méthode de conception de tableau de bord stratégique en sécurité de l’information pour le soutien de la conscience de la situation, qui permet à une partie prenante stratégique en sécurité de l’information d’avoir une bonne compréhension de son environnement. Ensuite, l’article offre un aperçu de la valeur de cette méthode en présentant une maquette de tableau de bord, conçue pour le CISO d'une institution financière canadienne et son équipe. Il documente aussi les défis rencontrés lors du processus de conception.Abstract: The Chief Information Security Officer (CISO) is the senior-level executive who ensures that the board and the executives have a good understanding of the current information security posture of the organization. To fulfill this objective, the CISO needs to have access to reliable, complete and relevant information in a timely manner to allow them to communicate effectively and to take the best decisions. Widely viewed as a great enabler of good performance management, the dashboard is a one-pager summary of the information that allows users to meet their objectives. This paper describes a method that makes it possible to consistently design dashboards that support situation awareness, giving users a good understanding of their environment in order for them to reach their goals. It then creates an example of such a dashboard that targets information security strategic stakeholders such as the CISO in the context of a Canadian financial institution, giving insights into the challenges faced in the design process

Cyber Threat Observatory: Design and Evaluation of an Interactive Dashboard for Computer Emergency Response Teams

Computer emergency response teams (CERTs) of the public sector provide preventive and reactive cybersecurity services for authorities, citizens, and enterprises. However, their tasks of monitoring, analyzing, and communicating threats to establish cyber situational awareness are getting more complex due to the increasing information volume disseminated through public channels. Besides the time-consuming data collection for incident handling and daily reporting, CERTs are often confronted with irrelevant, redundant, or incredible information, exacerbating the time-critical prevention of and response to cyber threats. Thus, this design science research paper presents the user-centered design and evaluation of the Cyber Threat Observatory, which is an automatic, cross-platform and real-time cybersecurity dashboard. Based on expert scenario-based walkthroughs and semi-structured interviews (N=12), it discusses six design implications, including customizability and filtering, data source modularity, cross-platform interrelations, content assessment algorithms, integration with existing software, as well as export and communication capabilities

Application of the JDL data fusion process model for cyber security,”

ABSTRACT A number of cyber security technologies have proposed the use of data fusion to enhance the defensive capabilities of the network and aid in the development of situational awareness for the security analyst. While there have been advances in fusion technologies and the application of fusion in intrusion detection systems (IDSs), in particular, additional progress can be made by gaining a better understanding of a variety of data fusion processes and applying them to the cyber security application domain. This research explores the underlying processes identified in the Joint Directors of Laboratories (JDL) data fusion process model and further describes them in a cyber security context
