Defining the Behavior of IoT Devices through the MUD Standard: Review, Challenges, and Research Directions

With the strong development of the Internet of Things (IoT), the definition of IoT devices' intended behavior is key for an effective detection of potential cybersecurity attacks and threats in an increasingly connected environment. In 2019, the Manufacturer Usage Description (MUD) was standardized within the IETF as a data model and architecture for defining, obtaining and deploying MUD files, which describe the network behavioral profiles of IoT devices. While it has attracted a strong interest from academia, industry, and Standards Developing Organizations (SDOs), MUD is not yet widely deployed in real-world scenarios. In this work, we analyze the current research landscape around this standard, and describe some of the main challenges to be considered in the coming years to foster its adoption and deployment. Based on the literature analysis and our own experience in this area, we further describe potential research directions exploiting the MUD standard to encourage the development of secure IoT-enabled scenarios

Association between polycystic ovary and fibrocystic breast disease

The aim of this study was to assess whether or not there was an association between a polycystic ovary (PCO) and fibrocystic breast disease based on ultrasound findings, both pelvic and mammographic. Prospective case-control study. Women aged between 18 and 30 years not using oral contraceptives attending the outpatient ultrasound clinic from January 1996 to December 1998. Confirm the association between PCO and fibrocystic breast disease. According to the ultrasound findings, women were allocated to three groups: 351 out of 456 showed normal-appearing ovaries (group A), 93 had polycystic-appearing ovaries/PCO (group B) and 12 had PCO syndrome (group C). In group A, 24 (6.83%) women showed breast pathology. In group B, there was an association between PCO and breast pathology in 53 (56.98%) women, while in group C it was noted in 11 out of 12 (91%). This study showed a significant association between PCO and benign pathology. This should encourage the performance of a screening breast sonography on women with PCO
