Suitable models that auditors can adopt to concurrently audit smart Intrusion Detection Systems (IDSs) and log analyzers in Cyber Physical Systems (CPSs) that are also founded on sound empirical claims are scarce. Recently, post-intrusion studies on the resilience of the above mechanisms and prevalence of intrusions in the above domains have shown that certain intrusions that can reduce the performance of smart IDSs can equally overwhelm log analyzers such that both mechanisms can gradually dwindle and suddenly stop working. Studies have also shown that several components of Cyber Physical Systems have unusual vulnerabilities. These key issues often increase cyber threats on data security and privacy of resources that many users can receive over Internet of a Thing (IoT). Dreadful intrusions on physical and computational components of Cyber Physical Systems can cause systemic reduction in global economy, quality of digital services and continue usage of smart toolkits that should support risk assessments and identification of strategies of intruders. Unfortunately, pragmatic studies on how to reduce the above problems are grossly inadequate. This chapter uses alerts from Snort and C++ programming language to practically explore the above issues and further proposes a feasible model for operators and researchers to lessen the above problems. Evaluation with real and synthetic datasets demonstrates that the capabilities and resilience of smart Intrusion Detection Systems (IDSs) to safeguard Cyber Physical Systems (CPSs) can be improved given a framework to facilitate audit of smart IDSs and log analyzers in Cyberspaces and knowledge of the variability in the lengths and components of alerts warned by Smart Intrusion Detection Systems (IDSs).

Spectacular developments that were recorded in the field of software engineering in recent years have led to the influx of software industry with series of computer apps such as dating apps, games apps, entertainment apps, banking apps, Photoshop apps, meetings and virtual conferencing apps. Studies have shown that most computer apps are widely accessible to adults and juveniles to download and effortlessly navigate through them. However, researchers have now revealed the existence of malware apps as new groups of computer apps that are strongly competing with legitimate computer apps and the latest rates at which some juveniles can adopt them to commit crimes. These discoveries have raised serious doubts about the elements of the crimes, the circumstances that surround vulnerable children to commit the crimes and how these dilemmas are rarely buttressed by pragmatic studies over the years. This chapter adopts mixed methods to critically explore the above issues. Qualitative interviews of 60 teenagers (between the ages of 10 and 17) and 20 grown-up children (between the ages of 18 and 22) together with 5 professionals were carried out. The analysis extended the generic elements of juvenile crime and raised new legal dilemmas regarding the concepts of transfer of criminal liability, compelled (or obligated) liability, ‘act’ that constitutes juvenile crimes and the restrictive applicability regarding criminal consent of extremely young children that are still under the tutelage and guidance of their parents.
