    AI Based Monitoring System for Social Engineering
    (IEEE, 2021-12-09) Abeywardana, K. Y; Udara, S. W. I; Wijayawardane, U. P. B; Kularatne, K. N. P; Navaratne, N. M. P. P; Dharmaphriya, W. G. V. U
    Social media is one of the most predominantly used online platforms by individuals across the world. However, very few of these social media users are educated about the adverse effects of obliviously using social media. Therefore, this research project, is to develop an advisory system for the benefit of the general public who are victimized by the adverse impacts of their ignorant and oblivious behavior on social media. The system was implemented using a decision tree model with the use of customized datasets; and for the proceeding operational implementations, Python programming language, Pandas, Natural Language Processing and TensorFlow were used. This advisory system can monitor user behaviors and generate customized awareness reports for the users based on category and level of their behaviors on social media. Furthermore, the system is also capable of generating graph reports of the use behavior fluctuations for the reference of the user. With the help of these customized awareness reports and the graph reports, the users can identify their potential vulnerabilities and improve their social media habits.

    Improve the Efficiency and Security by Digitalizing the Sri Lankan Police Department
    (IEEE, 2021-12-09) Senaratne, A. N; Abeywardana, K. Y; Pathirathna, R. P. D.T. D; Priyamantha, Y. P. C. N; Dias, W. D. S; Katukithulgala, B
    Police, as the main law enforcement organization in Sri Lanka, play a major role in preserving the public order, preventing criminal, terrorist activities, and enforcing the law. As a developing nation, Sri Lanka Police Department is moving forward with emerging technologies to effectively manage operations and rapidly respond to opportunities and challenges. Compared to developed countries, Police Department is still far more behind when working with modern technologies. Lack of coordination between departments, duplication of data, delay of services, unauthorized data modification, absence of data analysis and prediction systems, lack of transparency, and corruption were identified as the main issues that exist in the police department. In this paper, we propose 4 main improvements which help to overcome those issues and challenges. Improving the existing police clearance certificate system to issue digital certificates capable of verifying the authenticity, integrity of the document and providing efficient delivery and great user experience to the applicants. Implementing a Blockchain network to store confidential data securely by providing transparency and integrity. Developing a machine learning model to predict crimes geographically and predict fight crime action based on data gathered from a real-time camera system (CCTV).

    Improve the Efficiency and Security by Digitalizing the Sri Lankan Police Department

    A layered defense mechanism for a social engineering aware perimeter
    (IEEE, 2016-07-13) Abeywardana, K. Y; Pfluegel, E; Tunnicliffe, M. J
    While many cyber security organizations urge the corporate world to use defence-in-depth to create vigilant network perimeters, the human factor is often overlooked. Security evaluation frameworks focus mostly on critical assets of an organization and technical aspects of prevailing risks. There is consequently no specific framework to identify, categorize, analyse and mitigate social engineering related risks. This paper identifies the requirement for such a framework through an in-depth investigation of an actual organization and extensive analysis of existing methodologies. On the basis of this a layered defence strategy SERA is developed, starting with the basic building blocks for social-engineering aware risk analysis. A chronological attack classification framework is presented as an enhancement of existing frameworks on social engineering.
