Sommario/riassunto

Implement robust end-to-end security for your Hadoop ecosystem Master the key concepts behind Hadoop security as well as how to secure a Hadoop-based Big Data ecosystem Understand and deploy authentication, authorization, and data encryption in a Hadoop-based Big Data platform Administer the auditing and security event monitoring system In Detail Security of Big Data is one of the biggest concerns for enterprises today. How do we protect the sensitive information in a Hadoop ecosystem? How can we integrate Hadoop security with existing enterprise security systems? What are the challenges in securing Hadoop and its ecosystem? These are the questions which need to be answered in order to ensure effective management of Big Data. Hadoop, along with Kerberos, provides security features which enable Big Data management and which keep data secure. This book is a practitioner’s guide for securing a Hadoop-based Big Data platform. This book provides you with a step-by-step approach to implementing end-to-end security along with a solid foundation of knowledge of the Hadoop and Kerberos security models. This practical, hands-on guide looks at the security challenges involved in securing sensitive data in a Hadoop-based Big Data platform and also covers the Security Reference Architecture for securing Big Data. It will take you through the internals of the Hadoop and Kerberos security



models and will provide detailed implementation steps for securing Hadoop. You will also learn how the internals of the Hadoop security model are implemented, how to integrate Enterprise Security Systems with Hadoop security, and how you can manage and control user access to a Hadoop ecosystem seamlessly. You will also get acquainted with implementing audit logging and security incident monitoring within a Big Data platform.

Sommario/riassunto

Vaalikoneilla on Suomessa yli 20 vuoden historia. Suurin osa suomalaisista vaalikoneista on median toteuttamia ehdokasvaalikoneita. Niiden merkitys vaalitiedon lähteenä on kohonnut maassamme merkittäväksi lähes kaikissa äänioikeutettujen ikäryhmissä. Nuorimmille äänestäjille vaalikoneet ovat jo merkittävin äänestyspäätösten tietolähde. Teos tarjoaa ajantasaisen ja kattavan kuvan vaalikoneiden nykyisestä asemasta suomalaisessa poliittisessa järjestelmässä ja viestintäkentässä. Uusia tutkimuksellisia näkökulmia ovat vaalikonejournalismi sekä ehdokkaiden näkemykset vaalikoneista. Tutkimusaineisto koostuu valitsijakyselyistä, vaalikoneiden analyysista, vaalikoneita koskevista uutisista sekä ehdokkaiden, kampanjavastaavien ja vaalikoneiden tekijöiden haastatteluista. Kirja lähestyy vaalikoneita erilaisista demokratianäkökohdista ja pohtii laajasti myös vaalikoneiden kehittämismahdollisuuksia.

"Voting advice applications (VAA) have supported Finnish voters for over 20 years in their voting decisions in general elections. Most Finnish VAAs are planned and provided by the media, and they are based on matching opinions of individual candidates with an individual VAA users before elections. Nowadays, in Finland, VAAs are important for almost all age groups. Among the youngest voters VAAs are viewed as the most important source of information to support voting decisions.The book provides up-to-date and comprehensive picture over the role and significance of VAAs in the Finnish political system and in the political communication arena. Research topics deal also with VAA journalism and how candidates perceive VAAs. Research data and data materials in use are wide-ranging. They range from survey data sets to questions of VAAs and from interviews of candidates and VAA producers to media content about VAAs. Theoretical research questions are mostly related to the democratic value of VAAs. This perspective is central also in the end of the book, which opens possible future pathways for the VAAs."
