The year 2020 marked an important moment when the COVID-19 pandemic promoted Internet as a necessity even more than before, especially for school activities and businesses. This increased usage emphasized the importance of cybersecurity, a frequently overlooked subject by the common users, which in return plays a crucial role in safe Internet browsing. This paper introduces an approach grounded in Natural Language Processing techniques to identify the main trends in security news and empowers the analysis of vulnerable products, active attacks, as well as existing methods of defence against new attacks. Our dataset consists of 2264 news articles published on cybersecurity dedicated websites between January 2017 and May 2021. The RoBERTa language model was used to compute the texts embeddings, followed by dimensionality reduction techniques and topic clustering methods. Articles were grouped into approximately 20 clusters that were thoroughly evaluated in terms of importance and evolution. © 2021 IEEE.

Digital health tools hold the potential to improve the efficiency, accessibility and quality of care. Before the pandemic, efforts had been made to support implementation across Europe over many years, but widespread adoption in practice had been difficult and slow. The greatest barriers to adoption of digital health tools were not primarily technical in nature, but instead lay in successfully facilitating the required individual, organizational and system changes. During the COVID-19 pandemic many digital health tools moved from being viewed as a potential opportunity to becoming an immediate necessity, and their use increased substantially. Digital health tools have been used during the pandemic to support four main areas: communication and information, including tackling misinformation;surveillance and monitoring;the continuing provision of health care such as through remote consultations;and the rollout and monitoring of vaccination programmes. Greater use of digital health tools during the pandemic has been facilitated by: policy changes to regulation and reimbursement;investment in technical infrastructure;and training for health professionals. As the pandemic comes under control, if health systems are to retain added value from greater use of digital health tools, active strategies are needed now to build on the current momentum around their use. Areas to consider while developing such strategies include: Ensuring clear system-level frameworks and reimbursement regimes for the use of digital health tools, while allowing scope for co-design of digital health solutions by patients and health professionals for specific uses. Combining local flexibility with monitoring and evaluation to learn lessons and ensure that digital health tools help to meet wider health system goals.
