Novel Alert Visualization: The Development of a Visual Analytics Prototype for Mitigation of Malicious Insider Cyber ThreatsClarke, Karla A. 01 January 2018 (has links)
Cyber insider threat is one of the most difficult risks to mitigate in organizations. However, innovative validated visualizations for cyber analysts to better decipher and react to detected anomalies has not been reported in literature or in industry. Attacks caused by malicious insiders can cause millions of dollars in losses to an organization. Though there have been advances in Intrusion Detection Systems (IDSs) over the last three decades, traditional IDSs do not specialize in anomaly identification caused by insiders. There is also a profuse amount of data being presented to cyber analysts when deciphering big data and reacting to data breach incidents using complex information systems.
Information visualization is pertinent to the identification and mitigation of malicious cyber insider threats. The main goal of this study was to develop and validate, using Subject Matter Experts (SME), an executive insider threat dashboard visualization prototype. Using the developed prototype, an experimental study was conducted, which aimed to assess the perceived effectiveness in enhancing the analysts’ interface when complex data correlations are presented to mitigate malicious insiders cyber threats. Dashboard-based visualization techniques could be used to give full visibility of network progress and problems in real-time, especially within complex and stressful environments. For instance, in an Emergency Room (ER), there are four main vital signs used for urgent patient triage. Cybersecurity vital signs can give cyber analysts clear focal points during high severity issues. Pilots must expeditiously reference the Heads Up Display (HUD), which presents only key indicators to make critical decisions during unwarranted deviations or an immediate threat.
Current dashboard-based visualization techniques have yet to be fully validated within the field of cybersecurity. This study developed a visualization prototype based on SME input utilizing the Delphi method. SMEs validated the perceived effectiveness of several different types of the developed visualization dashboard. Quantitative analysis of SME’s perceived effectiveness via self-reported value and satisfaction data as well as qualitative analysis of feedback provided during the experiments using the prototype developed were performed.
This study identified critical cyber visualization variables and identified visualization techniques. The identifications were then used to develop QUICK.v™ a prototype to be used when mitigating potentially malicious cyber insider threats. The perceived effectiveness of QUICK.v™ was then validated. Insights from this study can aid organizations in enhancing cybersecurity dashboard visualizations by depicting only critical cybersecurity vital signs.

Comparing Training Methodologies on Employee’s Cybersecurity Countermeasures Awareness and Skills in Traditional vs. Socio-Technical ProgramsGoode, Jodi 01 January 2018 (has links)
Organizations, which have established an effective technical layer of security, continue to experience difficulties triggered by cyber threats. Ultimately, the cybersecurity posture of an organization depends on appropriate actions taken by employees whose naive cybersecurity practices have been found to represent 72% to 95% of cybersecurity threats and vulnerabilities to organizations. However, employees cannot be held responsible for cybersecurity practices if they are not provided the education and training to acquire skills, which allow for identification of security threats along with the proper course of action to mitigate such threats. In addition, awareness of the importance of cybersecurity, the responsibility of protecting organizational data, as well as of emerging cybersecurity threats is quickly becoming essential as the threat landscape increases in sophistication at an alarming rate. Security education, training, and awareness (SETA) programs can be used to empower employees, who are often cited as the weakest link in information systems (IS) security due to limited knowledge and lacking skillsets. Quality SETA programs not only focus on raising employee awareness of responsibilities in relation to their organizations’ information assets but also train on the consequences of abuse while providing the necessary skills to help fulfill these requirements.
The main goal of this research study was to empirically assess if there are any significant differences on employees’ cybersecurity countermeasures awareness (CCA) and cybersecurity skills (CyS) based on the use of two SETA program types (typical & socio-technical) and two SETA delivery methods (face-to-face & online). This study included a mixed method approach combining an expert panel, developmental research, and quantitative data collection. A panel of subject matter experts (SMEs) reviewed the proposed SETA program topics and measurement criteria for CCA per the Delphi methodology. The SMEs’ responses were incorporated into the development of two SETA program types with integrated vignette-based assessment of CCA and CyS, which were delivered via two methods. Vignette-based assessment provided a nonintrusive way of measurement in a pre- and post-assessment format. Once the programs had been reviewed by the SMEs to ensure validity and reliability, per the Delphi methodology, randomly assigned participants were asked to complete the pre-assessment, the SETA program, and then the post-assessment providing for the qualitative phase of the study. Data collected was analyzed using analysis of variance (ANOVA) and analysis of covariance (ANCOVA) to address the proposed research hypothesis. Recommendations for SETA program type and delivery method as a result of data analysis are provided.
