- CROSS-PLATFORM DEVELOPMENT FOR E-COMMERCEPublication . Vieira, Leandro; Bernardino, Anabela; Bernardino, EugéniaElectronic commerce is generally seen as a competitor for physical stores, however, this paper proposes a solution where they work side-by-side to improve the in-store customer experience. An application directed for store retailers was created with the cross-platform framework React Native, making it available for Android, iOS, and the web. Using thebe of their interest, and place orders, providing the customer with a unique and faster shopping experience.
- Identifying Attack Signatures for the Internet of Things: An IP Flow Based ApproachPublication . Vieira, Leandro; Santos, Leonel; Goncalves, Ramiro; Rabadão, CarlosAt the time of more and more devices being connected to the internet, personal and sensitive information is going around the network more than ever. Thus, security and privacy regarding IoT communications, devices, and data are a concern due to the diversity of the devices and protocols used. Since traditional security mechanisms cannot always be adequate due to the heterogeneity and resource limitations of IoT devices, we conclude that there are still several improvements to be made to the 2nd line of defense mechanisms like Intrusion Detection Systems. Using a collection of IP flows, we can monitor the network and identify properties of the data that goes in and out. Since network flows collection have a smaller footprint than packet capturing, it makes it a better choice towards the Internet of Things networks. This paper aims to study IP flow properties of certain network attacks, with the goal of identifying an attack signature only by observing those properties.
