Government digital agendas worldwide go hand in hand with the digital transformation in businesses and public administrations as well as the digital changes taking place in society. Information security (IS) and awareness (ISA) must be an integrated part of these agendas. The goal of IS is to protect information of all types and origins. Here, the employees play a necessary and significant role in the success of IS, and the entire staff of an institution need to know about their specific roles and be aware of the information security management system (ISMS). As there are still fundamental strategic deficiencies in the institutions themselves, humans should not be called “the weakest link” in the security chain. Rather, sustainable awareness-raising and training for people should be established in the institutions using interactive, authentic, and game-based learning methods. Psychological studies show the great importance of emotionalization when communicating IS knowledge and the reliable exchange of experience about IS. However, in many institutions, a change in culture is becoming necessary. IS must be integrated into all (business) processes and projects, and viable safeguards must be included. This chapter summarizes the most important scientific findings and transfers them to the practice of public administrations in Germany. Moreover, it shows examples of learning methods and provides practical assistance for IS sensitization and training.

Comprehensive digitization leads to new chal-lenges because of cybercrime and related security countermeasures. There is no doubt that this will fundamentally affect our lives and is leading to an increase in the importance of information security (IS). However, technology solutions alone are not sufficient to ensure IS countermeasures. The human side of security is important to protect organizational assets like user information and systems. The paper illustrates these relationships in terms of information security awareness (ISA), examining its goals and the factors influencing it through the systematic analysis and review of scientific literature and the transfer of scientific knowledge for practical purposes. We reviewed the publications of leading academic journals in the field of IS over the past decade.
Femtosecond-Pulsed Laser Written and Etched Fiber Bragg Gratings for Fiber-Optical Biosensing
(2018)
We present the development of a label-free, highly sensitive fiber-optical biosensor for online detection and quantification of biomolecules. Here, the advantages of etched fiber Bragg gratings (eFBG) were used, since they induce a narrowband Bragg wavelength peak in the reflection operation mode. The gratings were fabricated point-by-point via a nonlinear absorption process of a highly focused femtosecond-pulsed laser, without the need of prior coating removal or specific fiber doping. The sensitivity of the Bragg wavelength peak to the surrounding refractive index (SRI), as needed for biochemical sensing, was realized by fiber cladding removal using hydrofluoric acid etching. For evaluation of biosensing capabilities, eFBG fibers were biofunctionalized with a single-stranded DNA aptamer specific for binding the C-reactive protein (CRP). Thus, the CRP-sensitive eFBG fiber-optical biosensor showed a very low limit of detection of 0.82 pg/L, with a dynamic range of CRP detection from approximately 0.8 pg/L to 1.2 µg/L. The biosensor showed a high specificity to CRP even in the presence of interfering substances. These results suggest that the proposed biosensor is capable for quantification of CRP from trace amounts of clinical samples. In addition, the adaption of this eFBG fiber-optical biosensor for detection of other relevant analytes can be easily realized.
