In the current business environment, organizations of all sizes, regardless of their area of expertise, are vulnerable to a substandard level of understanding the implications of delayed or missing preventive actions, corroborated with the prevalence of security incidents. The article aims to provide an in-depth analysis, visually facilitated by the Fault Tree Analysis of physical access vulnerabilities, to propose solutions based on the authors’ multidisciplinary expertise in order to tighten security protocols, and to assist organizations to be in compliance with international regulations and standards. Consequently, organizations will improve their reputation and customer assurance, avoid security violation-related fines, strengthen their internal confidence, boost the marketing and sales prospects, and ensure business continuity, by implementing security controls based on procedures and policies as part of an ISMS, providing the necessary training for all personnel, and enforcing multi-layer physical security systems, with a focus on restricted areas, facilitated by the usage of a redundant structure comprised of thermal cameras, movement sensors and improved Velostat keypads.
Dependability of electronic circuits can be ensured only through testing of circuit modules. This is done by generating test vectors and their application to the circuit. Testability should be viewed as a concerted effort to ensure maximum efficiency throughout the product life cycle, from conception and design stage, through production to repairs during products operating. In this paper, is presented the platform developed by authors for training for testability in electronics, in general and in using signature analysis method, in particular. The platform allows highlighting the two approaches in the field namely analog and digital signature of circuits. As a part of this e-learning platform, it has been developed a database for signatures of different electronic components meant to put into the spotlight different techniques implying fault detection, and from this there were also self-repairing techniques of the systems with this kind of components. An approach for realizing self-testing circuits based on MATLAB environment and using signature analysis method is proposed. This paper analyses the benefits of signature analysis method and simulates signature analyzer performance based on the use of pseudo-random sequences, too.
