A SURVEY OF SECURITY THREATS IN DISTRIBUTED OPERATING SYSTEM

— Over the last years, the security into software systems especially in the distributed system becomes complex day by day. The secure and trusted environment is a considerably important subject to address. Different services and resources in the distributed system have to be secure at different levels, for this reason, we have analysed in detail the flaws of the distributed systems, all the security threats, situations where the system at risk faces, and the best possible solutions to secure the distributed system. Globus security mechanism is discussed in detail well as how the authentication can be done and how do we achieve message confidentiality and integrity. Every idea that radiates all sorts of solutions to this matter is verified and well-studied. It provides the proper knowledge to help one understand the meaning of a secure system, the security policies, and the security mechanism.
