The brewing industry has devoted much research effort into the development of new technologies and innovations for the expansion of the assortment of specialty beers in response to increased consumer demand. Specialty beers are more or less the catch-all for beer styles, which do not fit into conventional beer categories and five types of specialty beers are of particular interest -low-calorie beer, low-alcohol or nonalcohol beer, novel-flavoured beer, gluten-free beer and functional beer. The selected beer types are technologically challenging to produce relative to the traditional approach of ingredient addition, yet offer special appeal to consumers from the perspective of health and flavour. Biological processes that make use of the equipment of a traditional brewery plant should be better exploited in comparison with nonbiological technologies such as thermal and membrane processes. Probiotic beer could be the specialty beer of the future in light of the increasing popularity of probiotics. These beers are reviewed in terms of developments, challenges and prospects.

In recent years, wireless networks have undoubtedly become a convenient way to connect to the Internet and provide connection to everyone in any corner of the world. In fact, in this era, people are connected to the internet almost everyday and wireless networks give us this privilege in a seamless manner. A wireless network normally consists of access points and nodes where the access points are responsible to amplify the wireless signals, while the nodes are the gadgets that are receiving these signals. However, with such great convenience provided, many challenges are also faced by the users and stakeholders. With no physical connection to devices, wireless networks are evidently more vulnerable to invisible cyber attacks. In this research paper, it the security issues that cause issues in the wireless networks are discussed. Furthermore, an analytical review of privacy challenges found in these networks is performed; these challenges are segregated into security issues and privacy issues. The paper will then present the methods used in conducting a survey and gathering the research results along with further discussion on the results obtained through this study. Finally, a suitable solution is proposed to prevent and overcome the intrusions faced in terms of security and privacy in wireless network scenarios through detection and response mechanism for mitigation of the problems.
