Our world is hugely impacted by revolutionary innovations in telecommunication technologies where connected objects increase rapidly. The Web of Things (WoT) represents the most promising application models of the Internet of Things (IoT). The ultimate goal of the WoT is to create a search engine where the user or devices can find other devices anywhere and anytime in order to take advantage of the resources of other devices. Nowaday, IoT systems imperatively need scalability and flexible coupling, which are easily offered by WoT. However, researchers have raised some concerns about the security of WoT. This paper provides a recent review of WoT literature. A special attention is accorded to the most relevant WoT security issues. Our paper also deals with the most important attacks in the domain and with some selected security solutions.
