“…Further more [11] introduces the use of a security metric based on measuring the extent of the relationship between the user and the system, identifying two key aspects , the system complexity and the knowledge of the user towards the system itself and proposes a metric based minimum untrustworthiness.…”

“…We start assuming that quantifying the level of trust, especially in social networks , is a hard and not standard preposition, especially since, citing work from [11], trust is much more dependant from what is unknown than what is known. Achieving trust and security on a Social Network scale which might range from few thousand to the millions, can be considered a problem of unequal entity.…”

The continuous growth of the users pool of Social Networking web sites such as Facebook and MySpace, and their incessant augmentation of services and capabilities will in the future, meet and compare in contrast with today's Content distribution Networks (CDN) and Peer-to-Peer File sharing applications such as Kazaa and BitTorrent, but how can these two main streams applications, that already encounter their own security problems cope with the combined issues, trust for Social Networks, content and index poisoning in CDN? We will address the problems of Social Trust and File Sharing with an overlay level of trust model based on social activity and transactions, this can be an answer to enable users to increase the reliability of their online social life and also enhance the content distribution and create a better file sharing example. The aim of this research is to lower the risk of malicious activity on a given Social Network by applying a correlated trust model, to guarantee the validity of someone's identity, privacy and trustfulness in sharing content.

Abstract. This paper presents an overview on how existing development methodologies and practices support the creation of trustworthy software. Trustworthy software is key for a successful and trusted usage of software, specifically in the Cloud. To better understand what trustworthy software applications actually mean, the concepts of trustworthiness and trust are defined and put in contrast to each other. Furthermore, we identify attributes of software applications that support trustworthiness. Based on this groundwork, some wellknown software development methodologies and best practices are analyzed with respect on how they support the systematic engineering of trustworthy software. Finally, the state of the art is discussed in a qualitative way, and an outlook on necessary research efforts and technological innovations is given.

“…The formulation of a methodology for the composing of such individually evaluated components of systems such that the security is ensured is still a research question with no concrete answers and furthermore, no system-design level methodology exists to compose such individuality. Also, very few methodologies exist that quantify the amount of security provided by a particular system [11,12] and not much either that talk about quantifying security beyond the application level i.e. at the system design level.…”
