Cloud security and compliance - a semantic approach in end to end security

Abstract: Dr. R. Udayakumar Research Supervisor, Associate Professor, Department of Information Technology, Bharath University, Chennai, India ABSTRACT The Cloud services are becoming an essential part of many organizations. Cloud providers have to adhere to security and privacy policies to ensure their users' data remains confidential and secure. Though there are some ongoing efforts on developing cloud security standards, most cloud providers are implementing a mishmash of security and privacy controls. This has led to confusion among cloud consumers as to what security measures they should expect from the cloud services, and whether these measures would comply with their security and compliance requirements. We have conducted a comprehensive study to review the potential threats faced by cloud consumers and have determined the compliance models and security controls that should be in place to manage the risk. Based on this study, we have developed an ontology describing the cloud security controls, threats and compliances. We have also developed an application that classifies the security threats faced by cloud users and automatically determines the high level security and compliance policy controls that have to be activated for each threat. The application also displays existing cloud providers that support these security policies. Cloud consumers can use our system to formulate their security policies and find compliant providers even if they are not familiar with the underlying technology.

Enhancing the Wear Resistance of 100Cr6 Bearing Steel Using Cryogenic Treatment

Abstract: The purpose of this study is to examine the effect of cryogenic treatment on the enhancement of the wear resistance of 100Cr6 bearing steel. The study also aims to reveal the underlying mechanisms responsible for the enhancement of wear resistance by deep cryogenic treatment (DCT) at −185°C. The wear behavior was assessed by a reciprocatory friction and wear monitor under varying normal loads (ASTM International, Annual Book of Standards, 1996). It was found that the wear resistance was increased by 37% due to DCT when compared with that of conventional heat treatment (CHT). A scanning electron microscopy (SEM) study was also conducted to identify the possible mechanism that augments the improvement in the wear resistance of cryogenically treated 100Cr6 bearing steels. The microstructural study suggests that the improvement in the wear resistance is attributed to the conversion of the retained austenite into martensite, along with the precipitation and distribution of the carbides brought in by the cryoge...
