This research paper describes and extends the outcomes from an in- depth study investigating the difference in the expected skills requirements from junior software engineers to senior software engineers, and reflections on the findings from that study. It is a given that senior software engineers have more experience and skills than junior software engineers. However, a focus on their differing competencies and dispositions provides an enhanced mechanism for comparison. Gaps were identified in assessing 'professional knowledge' as categorized by the IEEE/ACM Computing Curriculum Overview Report (CC2020), and in assessing 'dispositions'. It appeared that the specific scenario of comparing the expected competencies between junior and senior software engineers, tested the framework for assessing competencies developed in the CC2020 project and applied in its mapping to the IEEE/ACM Computer science (CS2013) approved curriculum. In this study into the difference between Junior and Senior software Engineers, an initial review of relevant literature was conducted. The review found that research analyzing job requirements for software engineers of different levels was limited;'experience' as a keyword was seldom mentioned;and a common distinction was made between 'soft' and 'hard' skills - the latter being skills that were 'technical', such as programming languages, frameworks, libraries, and tools, whereas soft skills referred to skills such as personality traits, attitudes, and teamwork skills. In our extension of that work the notion of soft skills was unpacked into professional skills and dispositions. The process of mapping from the CC2020 competency framework to the CS2013 curriculum had deliberately modelled how to represent a competency-based rather than a knowledge-based curriculum. The critical deficiency identified here was the limitation imposed by adopting a skills framework based on the cognitive taxonomy, and thereby unwittingly omitting the crucial compani

The proliferation of collaborative technologies and the Internet of Things (IoT) has led to a greater diversity of devices. However, it also increased their vulnerability to potential attacks. The inherent heterogeneity and complexity of IoT devices make it difficult to accurately detect abnormal behavior, leaving them open to manipulation by attackers. To address this issue, we propose Talos, an innovative solution to detect abnormal device behavior in IoT systems. Talos employs advanced deep neural networks to analyze and comprehend historical event sequences, enabling it to accurately model the normal behaviors of IoT devices and detect any anomalies through reconstruction error. We evaluate our prototype on a real-world testbed and test it for three different anomaly cases. The experimental results demonstrate that Talos achieved high precision and recall, achieving an average F1-Score of 99.73% while raising only a few false alarms.
Cryptographic algorithms are fundamental to security. However, it has been shown that secret information could be effectively extracted through monitoring and analyzing the cache side-channel information (i.e., hit an...
