Alterar o algoritmo <strong>de</strong> criptografia atual<br />

Como o <strong>CA</strong> <strong>ARCserve</strong> <strong>Backup</strong> protege os da<strong>do</strong>s<br />

O algoritmo <strong>de</strong> criptografia atual (AES256) usa<strong>do</strong> <strong>para</strong> o <strong>CA</strong> <strong>ARCserve</strong> <strong>Backup</strong><br />

po<strong>de</strong> ser altera<strong>do</strong> modifican<strong>do</strong> o arquivo CryptoConfig.cfg. Esse arquivo inclui<br />

uma lista <strong>de</strong> to<strong>do</strong>s os algoritmos <strong>de</strong> criptografia suporta<strong>do</strong>s <strong>para</strong> os produtos<br />

<strong>do</strong> <strong>CA</strong> <strong>ARCserve</strong> <strong>Backup</strong> instala<strong>do</strong>s em seu computa<strong>do</strong>r. É possível alterar o<br />

algoritmo <strong>de</strong> criptografia atual <strong>para</strong> qualquer um <strong>do</strong>s valores <strong>de</strong> algoritmo<br />

candidato alternativo lista<strong>do</strong>s. Essa alteração afetará to<strong>do</strong>s os produtos <strong>do</strong> <strong>CA</strong><br />

<strong>ARCserve</strong> <strong>Backup</strong> (base, agentes e opções) instala<strong>do</strong>s na máquina.<br />

Para alterar o algoritmo <strong>de</strong> criptografia atual<br />

1. Execute o script cstop.bat <strong>para</strong> interromper to<strong>do</strong>s os serviços antes <strong>de</strong><br />

fazer a alteração.<br />

Criptografia <strong>de</strong> da<strong>do</strong>s <strong>do</strong> <strong>CA</strong> <strong>ARCserve</strong> <strong>Backup</strong><br />

O <strong>CA</strong> <strong>ARCserve</strong> <strong>Backup</strong> fornece a flexibilida<strong>de</strong> <strong>de</strong> uso <strong>de</strong> criptografia <strong>para</strong><br />

proteger da<strong>do</strong>s confi<strong>de</strong>nciais durante vários estágios <strong>do</strong> processo <strong>de</strong> backup.<br />

Geralmente, durante o processo <strong>de</strong> backup, quanto antes a criptografia <strong>de</strong><br />

da<strong>do</strong>s ocorrer, mais seguras serão as informações. No entanto, a velocida<strong>de</strong>, o<br />

<strong>de</strong>sempenho e as restrições <strong>de</strong> programação também são fatores a serem<br />
