Analysis of security in cloud platforms using OpenStack as case study
In the last few years, cloud computing has grown from being a promising
business concept to one of the fastest growing segments of the IT industry.
Big companies like Amazon, Google, Microsoft etc., expand their market by
adopting Cloud Computing systems which enhance their services provided
to a large number of users. However, security and privacy issues present a
strong barrier for users to adapt into the Cloud.This research investigates
the security features and issues of cloud platforms using OpenStack as a
case study. The goal was to identify security weakness in terms of
Authentication and Identity Management(IAM), and Data Management. Base
on the findings, specific recommendations on security standards and
management models have been proffered in order to address these problems.
These Recommendations if implemented, will lead to trust in cloud
computing systems, which in turn would encourage more companies to
adopt cloud computing, as a means of providing better IT services
A Survey on Security and Privacy of 5G Technologies: Potential Solutions, Recent Advancements, and Future Directions
Security has become the primary concern in many telecommunications industries today as risks can have high consequences. Especially, as the core and enable technologies will be associated with 5G network, the confidential information will move at all layers in future wireless systems. Several incidents revealed that the hazard encountered by an infected wireless network, not only affects the security and privacy concerns, but also impedes the complex dynamics of the communications ecosystem. Consequently, the complexity and strength of security attacks have increased in the recent past making the detection or prevention of sabotage a global challenge. From the security and privacy perspectives, this paper presents a comprehensive detail on the core and enabling technologies, which are used to build the 5G security model; network softwarization security, PHY (Physical) layer security and 5G privacy concerns, among others. Additionally, the paper includes discussion on security monitoring and management of 5G networks. This paper also evaluates the related security measures and standards of core 5G technologies by resorting to different standardization bodies and provide a brief overview of 5G standardization security forces. Furthermore, the key projects of international significance, in line with the security concerns of 5G and beyond are also presented. Finally, a future directions and open challenges section has included to encourage future research.European CommissionNational Research Tomsk Polytechnic UniversityUpdate citation details during checkdate report - A
