Criptografia Idea

child . Thinking about it, was designed a program similar a game, known since the past times, where the child can pass to the teacher if they have any difficulties that are preventing you from moving forward with studies. The application passes the idea of a memory game, where the child must see a picture by a certain time and then they will have to describe all the objects that have been deployed in this figure. The aim of the game is to prove that the child has greater difficulty…

convencionais, ou que suscitem o risco de perda de informações significativas ou ainda, a inviabilização da perícia são exemplos dessas circunstâncias. Destaque-se também a situação cada vez mais freqüente da possibilidade de haver configurada proteção por criptografia sobre os conteúdos armazenados em dispositivos de mídia dos equipamentos computacionais, o que também justifica procedimentos de análise forense live. Em análises forenses realizadas em equipamentos ligados e conectados, é…

administrative theory has become so indispensable to the success of the administrator and organizations. The constant need for innovation and renewal, the search for flexibility and agility to deliver change and transformation, the adoption of new ideas. Moreover, it is worth noting that the administrative theory formulates his propositions in terms of two basic constraints: time (history) and space (distance). The study and research in each class was part of the…

vários recursos de criptografia, tanto da comunicação quanto da base de dados existentes no PointBase. Em relação ao MySQL: “O MySQL utiliza segurança baseada em listas de controle de acesso (Access Control Lists – ACLs) para todas as conexões, consultas e outras operações. Ele também tem algum suporte a conexões criptografadas SSL entre clientes e servidores MySQL. A senha utilizada em conexões para um servidor MySQL não é transmitida em texto aberto na conexão, porém a criptografia…

verification that such images should have their access controlled in a way that only legitimate users could have access to these images. The basic idea is to do that any user that is connected to the net has to be identified and authorized to have access to the images of satellites. The implementation consists of a mechanism based on the idea of Captive Portals to identify the user and also of an authentication/authorization mechanism that allows to define differentiated accesses…

conducted by the "Internet World Stats" 1.96 billion people had access to the network in June 2010, but that this communication can be performed each device needs a unique address, which differentiates them from others. It is in this context that comes the idea of IP (Internet Protocol). And with the advancement of WEB worldwide increasingly larger numbers of devices are connecting to the Internet , as a result of this demand the amount of numbers available IPs are increasingly limited…

about. Conforme tratado a seguir. Status : A aba status mostra o atual modo do da placa de rede sem fio. Ele pode mostrar onde o dispositivo está conectado, o modo da rede (ad-hoc ou infra-estruturada), o canal e a taxa de transmissão e o modo de criptografia usado (veja Figura 5.2). Figura 5.2 – Características que demonstram a atual da configuração do adaptador de rede Configuration: Nessa aba de configuração estão as funções que ajudarão na configuração e segurança da rede (Figura…

computational environment, vulnerability research tools, and for the last the reader can find out the case study as it was researched about the identified failures in the enterprise security system studied as for example a non-updated antivirus and ideas for trying to give solution to the found matters. Key-words: Computer Science, digital security, hackers, cracker, vulnerabilities, false programs. 1 Introdução A segurança tem seu papel preponderante para o funcionamento…

Will be addressed in the project the issue of cloud computing technology. As everything starts from a need, then there was the need to get more out of the way of using the Hardware stocky servers worldwide and more a plausible way to earn money.The idea is to generate Hosting service, a complete environment for Web systems, servers or storage servers or database ... and collect the flow data stream that is feito.Os resources and practice can be understood more clearly through their…

acesso a internet por exemplo, precisa de um segurança menor a invasões do que um sistema e-commerce. Existem Firewalls (muralhas digitais, que fecham as portas de acesso pela internet, liberando só o conteúdo especifico e portas especificas), criptografia de dados (certificados digitais, https, transmissão criptografada) entre outro, senhas seguras, validação de sistema contra SQL injection e ataques de força bruta. Contra ameaças internas existem algumas maneiras também, tais como…
