Foreword The Center for Computer Sciences and Technology of the National Bureau of Standards has responsibility under the authority of Public Law 89-306 (the Brooks Bill) for automatic data processing standards development, for consultation and technical assistance to Federal agencies, and for supporting research in matters relating to the use of computers in the Federal Government. This selective literature review is the second in a series intended to improve interchange of information among those engaged in research and development in the fields of the computer and information sciences. Considered in this volume are the specific areas of information processing, storage, and output. Names and descriptions of specific proprietary devices and equipment have been included for the convenience of the reader, but completencsb in this respect is recognized to be impossible. Certain important developments have remained proprietary or have not been reported in the open literature; thus major contributors to key developments in the field may have been omitted. The omission of any method or device does not necessarily imply that it is considered unsuitable or unsatisfactory, nor does inclusion of descriptive material on commercially available instruments, products, programs, or processes constitute endorsement.

    Data Processing with Unit Record Equipment in Iceland

    Data Processing with Unit Record Equipment in Iceland Óttar Kjartansson (Retired) Manager of Data Processing Department at Skýrr, Iceland [email protected] Abstract. This paper presents an overview of the usage of unit record equipment and punched cards in Iceland and introduces some of the pioneers. The usage of punched cards as a media in file processing started 1949 and became the dominant machine readable media in Iceland until 1968. After that punched cards were still used as data entry media for a while but went completely out of use in 1982. Keywords: Data processing, unit record, punched card, Iceland. 1 Hagstofa Íslands Hagstofa Íslands (Statistical Bureau of Iceland) initiated the use of 80 column punched cards and unit record equipment in Iceland in the year 1949. The first ma- chinery consisted of tabulating machine of the type IBM 285 (handled numbers only), the associated key punch machines, verifiers, and a card sorter. See Figures 1 and 2. This equipment was primarily used to account for the import and export for Iceland. Skýrr (Skýrsluvélar ríkisins og Reykjavíkurborgar - The Icelandic State and Munici- pal Data Center) was established three years later by an initiative from Hagstofa Íslands, Rafmagnsveita Reykjavíkur (Reykjavík Electric Power Utility), and the Medical Director of Health of Iceland as was described in an earlier article [3].

    Virtualization and Security Aspects: an Overview

    Rui Filipe Pereira, Rui Miguel Silva & João Pedro Orvalho Virtualization and Security Aspects: An Overview Rui Filipe Pereira [email protected] Lab UbiNET – Computer Science Security and Cybercrime Polytechnic Institute Of Beja Beja, Portugal Rui Miguel Silva [email protected] Lab UbiNET – Computer Science Security and Cybercrime Polytechnic Institute Of Beja Beja, Portugal João Pedro Orvalho [email protected] Lab UbiNET – Computer Science Security and Cybercrime Polytechnic Institute Of Beja Beja, Portugal Abstract Virtualization allows a single system to concurrently run multiple isolated virtual machines, operating systems (OSes) or multiple instances of a single OS. It helps organizations to improve operational efficiency, reduce costs, improve the use of hardware, and to allocate resources on- demand. Nevertheless, like most technologies, it has vulnerabilities and threats. Research about security issues related to virtualization has been conducted for several years. However, there are still open challenges related to security in virtualization. This paper looks into some of the differences, issues, challenges, and risks caused by virtualization and aims to classify the various virtualization approaches, along with their goals, advantages and drawbacks from a security perspective. Such classification is expected to help in the identification of virtualization technologies that might be applied in a virtualized infrastructure. This work is intended to be an introduction to the security considerations, concerns, and implications arising from use of virtualized systems. Keywords: Virtualization, Cybersecurity, Hypervisor, Virtual Machine, Virtual Machine Monitor. 1. INTRODUCTION Virtualization is a technology that uses a logical environment to overcome the physical limitations of hardware. Due to its characteristics of encapsulation and isolation, virtualization is the basis for cloud computing paradigm.
