RESUMO

Grid computing is a concept that exploits the power of computer networks, with the specific aim of making virtual layers available that allow users to have access to highly demanding applications, as well as to adhere to large scale, highly diverse, virtual communities. Grid computing provides support for the execution of parallel applications, grouping together distributed heterogeneous resources, offering consistent and inexpensive access to them, independently of their geographical location. The technology of grid computing allow the gathering of different and disperse computer resources, accelerating the execution of various computer processes. To better understand security issues in grids, the principal focus of this work, a general study of grid computing including architecture, functionalities, applications and services was done, with the goal of identifying and demonstrating the existent complexity behind this scenery. Security is fundamental to a grid project. Security components must supply the correct mechanisms for secure communication, without which processed information inside a grid becomes vulnerable. The purpose of this work is to survey security issues in grid computing, identifying existent problems, solutions, architectures, tools and techniques. Based on this information it is possible to understand how security mechanisms in grids work, identifying those mechanisms already in place and working, as well as what is needed for the full development of grid computing
