Java File Security System JFSS
Nowadays, storage systems are increasingly subject to attacks. So the security system is quickly becoming mendatory feature of the data storage systems. For the security purpose we are always dependent on the cryptography techniques. These techniques take the performance costs for the complete system. So we have proposed the Java File Security System(JFSS). It is based on the on-demand computing system concept, because of the performance issues. It is a greate comback for the system performance. The concept is used because, we are not always in need the secure the files, but the selected one only. In this paper, we have designed a file security system on Windows XP. When we use the operating system, we have to secure some important data. The date is always stored in the files, so we secure the important files well. To check the proposed functionality, we experiment the above said system on the Windows operating system. With these experiments, we have found that the proposed system is working properly, according to the needs of the users
File System Design Approaches
In this article, the file system development design approaches are discussed.
The selection of the file system design approach is done according to the needs
of the developers what are the needed requirements and specifications for the
new design. It allowed us to identify where our proposal fitted in with
relation to current and past file system development. Our experience with file
system development is limited so the research served to identify the different
techniques that can be used. The variety of file systems encountered show what
an active area of research file system development is. The file systems may be
from one of the two fundamental categories. In one category, the file system is
developed in user space and runs as a user process. Another file system may be
developed in the kernel space and runs as a privileged process. Another one is
the mixed approach in which we can take the advantages of both aforesaid
approaches. Each development option has its own pros and cons. In this article,
these design approaches are discussed.Comment: 5 pages, 6 figure
Disponibilidade, desempenho e segurança do ambiente de tecnologia da informação com acordo de nível de serviços utilizando ATM
Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Ciência da Computação.Este trabalho apresenta uma proposta para implementação de recursos visando assegurar uma alta disponibilidade e segurança do ambiente de Tecnologia da Informação. Serão considerados os aspectos do Acordo de Nível de Serviço (SLA - Service Level Agreement), a implementação da tecnologia ATM (Asynchronous Trasnfer Mode) integrada às redes convencionais. O trabalho apresenta algumas propostas para as diretrizes de segurança da informação de uma organização, visando preservar a confidencialidade, integridade e disponibilidade das informações da instituição. Esta proposta é aplicável aos sistemas informatizados e os meios convencionais de processamento, comunicação e armazenamento de informações. O trabalho pretende fomentar a busca de orientação para a conduta considerada adequada aos negócios e aos objetivos da organização. Serão recomendadas tecnologias adequadas ao backbone da rede e ao Server Farm, apontando os pontos indispensáveis para manter uma disponibilidade de acordo com as exigências de um SLA. Serão sugeridas políticas de proteção das informações contra desnutrição, modificação e divulgação indevida, quer sejam acidentais ou intencionais. Serão destacadas as alternativas do LANE como serviço de integração das LANs convencionais ao ATM e o VRRP - Virtual Route Redundance Protocol (RFC 2338) como serviço de aumento da disponibilidade no backbone ATM e no Server Farm
Air Traffic Management Abbreviation Compendium
As in all fields of work, an unmanageable number of abbreviations are used today in aviation for terms, definitions, commands, standards and technical descriptions. This applies in general to the areas of aeronautical communication, navigation and surveillance, cockpit and air traffic control working positions, passenger and cargo transport, and all other areas of flight planning, organization and guidance. In addition, many abbreviations are used more than once or have different meanings in different languages.
In order to obtain an overview of the most common abbreviations used in air traffic management, organizations like EUROCONTROL, FAA, DWD and DLR have published lists of abbreviations in the past, which have also been enclosed in this document. In addition, abbreviations from some larger international projects related to aviation have been included to provide users with a directory as complete as possible. This means that the second edition of the Air Traffic Management Abbreviation Compendium includes now around 16,500 abbreviations and acronyms from the field of aviation
