ABSTRACT
The use of unified communication;video conferencing, audio conferencing, and instant messaging has skyrocketed during the COVID-19 pandemic. However, security and privacy considerations have often been neglected. This article provides a comprehensive survey of security and privacy in Unified Communication (UC). We systematically analyze security and privacy threats and mitigations in a generic UC scenario. Based on this, we analyze security and privacy features of the major UC market leaders, and we draw conclusions on the overall UC landscape. While confidentiality in communication channels is generally well protected through encryption, other privacy properties are mostly lacking on UC platforms. [ FROM AUTHOR]
ABSTRACT
As the pandemic continues, there is increasing hope vaccinations are becoming available. As a solution for a nationwide immunization against the virus, a compulsory vaccination is repeatedly discussed. However, some opponents of vaccination are threatened by the idea of a possible mandatory vaccination. It is therefore necessary to discuss whether such a compulsory vaccination is theoretically legally enforceable. This article discusses the current legal situation in Germany. The introduction of a potential compulsory vaccination against the SARS-CoV-2 virus represents an encroachment on the fundamental right of physical integrity. According to §â20 (6) IfSG, a protective vaccination for threatened parts of the population is permissible by statutory order, if a transmissible disease with clinically severe courses occurs and its epidemic spread can be expected.
