Com a seguran\u00e7a na mente de todos, as organiza\u00e7\u00f5es precisam executar cargas de trabalho confidenciais sob padr\u00f5es rigorosos de seguran\u00e7a e conformidade. A vers\u00e3o pr\u00e9via do Couchbase 6.5 traz v\u00e1rios novos recursos de seguran\u00e7a, e a criptografia n\u00f3 a n\u00f3 tem sido um dos principais itens da lista de desejos de muitos clientes. <\/span>
\n<\/span>
\n<\/span>Neste blog, forneceremos uma vis\u00e3o geral r\u00e1pida do novo recurso de criptografia n\u00f3 a n\u00f3, juntamente com etapas f\u00e1ceis de seguir para ajud\u00e1-lo a come\u00e7ar. <\/span>
\n<\/span>
\n<\/span>O que \u00e9 criptografia n\u00f3 a n\u00f3?<\/strong><\/p>\n

Em uma plataforma de dados distribu\u00edda, como o Couchbase Server, h\u00e1 basicamente dois tipos de informa\u00e7\u00f5es trocadas entre os n\u00f3s <\/span>
\n<\/span>
\n<\/span>1. Informa\u00e7\u00f5es de controle que incluem metadados de cluster, configura\u00e7\u00f5es, etc.<\/span>
\n<\/span>2. Dados do usu\u00e1rio, incluindo documentos JSON<\/span>
\n<\/span>
\n<\/span>Nas vers\u00f5es anteriores do Couchbase Server, a criptografia estava dispon\u00edvel entre o cliente e o servidor e para proteger o tr\u00e1fego XDCR entre os data centers. Na aus\u00eancia de um controle de seguran\u00e7a compensat\u00f3rio, como o IPSec em toda a rede, era poss\u00edvel que um invasor detectasse informa\u00e7\u00f5es no fio, desde que o acesso \u00e0 rede estivesse dispon\u00edvel. No entanto, alguns desses controles de compensa\u00e7\u00e3o eram dif\u00edceis de configurar ou implementar em escala.<\/span>
\n<\/span>
\n<\/span>Com o novo recurso de criptografia n\u00f3 a n\u00f3 no Couchbase 6.5, as informa\u00e7\u00f5es que est\u00e3o fluindo entre os n\u00f3s s\u00e3o criptografadas nativamente pelo Couchbase, sem a necessidade de instalar nenhum software de terceiros. Os n\u00edveis de criptografia permitem criptografar apenas o tr\u00e1fego do plano de controle ou todos (controle e dados) entre os n\u00f3s. Isso proporciona flexibilidade aos clientes para que eles possam escolher o n\u00edvel de criptografia adequado ao seu caso de uso, mantendo o desempenho em mente. <\/span>
\n<\/span>
\n<\/span>Isso n\u00e3o significa que a criptografia n\u00f3 a n\u00f3 resolva tudo. A criptografia n\u00f3 a n\u00f3 ainda complementa os controles de seguran\u00e7a existentes, incluindo a criptografia cliente a servidor, a criptografia sobre XDCR, a criptografia em repouso e a seguran\u00e7a e o isolamento em n\u00edvel de rede baseados em nuvem privada virtual (VPC). Quanto mais camadas de prote\u00e7\u00e3o voc\u00ea adicionar ao seu sistema, mais dif\u00edcil ser\u00e1 para um invasor compromet\u00ea-lo.<\/span><\/p>\n

De n\u00f3 para n\u00f3, n\u00e3o dentro de um n\u00f3<\/strong><\/p>\n

Com base no feedback dos clientes, o recurso de criptografia n\u00f3 a n\u00f3 foi adicionado \u00e0 vers\u00e3o 6.5. Esse recurso levou v\u00e1rios meses para ser desenvolvido, embora possa parecer que ele aplica um TLS geral em todos os n\u00f3s do cluster. A imagem a seguir mostra algumas das altera\u00e7\u00f5es feitas no gerenciador de clusters do Couchbase - <\/span>
\n<\/span>\"\"<\/span>
\n<\/span>A linha vermelha indica o <\/span>local<\/span><\/i> intera\u00e7\u00f5es que existem entre os diferentes processos no mesmo n\u00f3 f\u00edsico - VMs ns_babysitter, ns_server e ns_couchdb. A linha azul indica a <\/span>externo<\/span><\/i> intera\u00e7\u00f5es entre VMs ns_server em execu\u00e7\u00e3o em diferentes n\u00f3s do cluster. As intera\u00e7\u00f5es mostradas em vermelho sempre permaneceriam n\u00e3o criptografadas, independentemente de a criptografia do cluster estar ativada ou n\u00e3o. Isso ocorre porque n\u00e3o queremos sobrecarregar desnecessariamente os processos em execu\u00e7\u00e3o com criptografia. Por outro lado, as intera\u00e7\u00f5es externas (mostradas em azul) s\u00e3o criptografadas quando a criptografia de cluster est\u00e1 ativada.<\/span><\/p>\n

Como configurar a criptografia n\u00f3 a n\u00f3?<\/strong><\/p>\n

Configurar a criptografia n\u00f3 a n\u00f3 \u00e9 f\u00e1cil e, nesta se\u00e7\u00e3o, descreveremos as instru\u00e7\u00f5es passo a passo que voc\u00ea pode seguir para configur\u00e1-la.<\/span><\/p>\n

Etapa 1: <\/b>Instalar o Couchbase Server 6.5 em<\/span>\u00a02 n\u00f3s. Vamos chamar esses n\u00f3s de <\/span>n\u00f3-1 <\/b>e <\/span>n\u00f3-2<\/b>.<\/span><\/p>\n

Etapa 2: <\/b>Se este for um cluster totalmente novo, durante a configura\u00e7\u00e3o gr\u00e1fica dos n\u00f3s, voc\u00ea ser\u00e1 solicitado a selecionar se a criptografia n\u00f3 a n\u00f3 est\u00e1 ativada ou n\u00e3o. Por padr\u00e3o, a criptografia de n\u00f3 n\u00e3o est\u00e1 ativada.\u00a0<\/span><\/p>\n

Marque a op\u00e7\u00e3o \"enable cluster encryption\" (ativar criptografia de cluster)<\/b> na caixa de di\u00e1logo e prossiga.<\/span><\/p>\n

\"\"<\/p>\n

Essa configura\u00e7\u00e3o s\u00f3 \u00e9 aplic\u00e1vel se todos os n\u00f3s do cluster forem da vers\u00e3o 6.5 ou superior. Se este for um novo cluster 6.5, todos os novos n\u00f3s que ingressarem no cluster herdar\u00e3o essa configura\u00e7\u00e3o.\u00a0<\/span><\/p>\n

No caso de um cluster existente atualizado para a vers\u00e3o 6.5 ou de um novo cluster, essa opera\u00e7\u00e3o tamb\u00e9m pode ser feita usando o comando CLI, conforme mostrado abaixo -<\/span><\/p>\n\n\n\n
$> <\/span>.\/couchbase-cli <\/span>criptografia de n\u00f3 para n\u00f3<\/b> -c localhost:8091 -u -p <\/span>-habilitado<\/b><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Etapa 3:<\/b> Verifique a configura\u00e7\u00e3o para garantir que a criptografia do cluster esteja ativada<\/span><\/p>\n\n\n\n
.\/couchbase-cli <\/span>configura\u00e7\u00e3o de seguran\u00e7a<\/b> -get -c localhost:8091 -u -p<\/span><\/p>\n

{\"disableUIOverHttp\": false, \"disableUIOverHttps\": false, <\/span>\"clusterEncryptionLevel\": \"control\"}<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Observe que, por padr\u00e3o, o n\u00edvel de criptografia do cluster \u00e9 definido como <\/span>controle<\/b>. Isso significa que os dados entre os n\u00f3s ainda n\u00e3o s\u00e3o criptografados, mas o plano de controle \u00e9 criptografado.<\/span><\/p>\n

Etapa 4:<\/b> Usando o netstat para verificar as portas abertas em <\/span>n\u00f3-1<\/b> de sa\u00edda para <\/span>n\u00f3-2. <\/b>Quando h\u00e1 <\/span>sem criptografia em vigor, as portas 21100 a 21299 s\u00e3o usadas<\/b> para troca de dados. Para <\/span>Nas conex\u00f5es TLS entre os n\u00f3s, sempre usamos a porta 21150<\/b>.\u00a0<\/span><\/p>\n

Voc\u00ea precisar\u00e1 usar o sudo como 'root' para executar esse comando -\u00a0<\/span><\/p>\n\n\n\n
$> <\/span>netstat<\/b> -atep -numeric-ports | <\/span>grep 'beam.smp' | grep 'node-2'<\/b>\u00a0<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Etapa 5:<\/b> Se voc\u00ea for corajoso o suficiente, poder\u00e1 dar um passo adiante usando o pacote tshark (wireshark) e capturar pacotes TCP. Esta \u00e9 a apar\u00eancia da sa\u00edda<\/span><\/p>\n\n\n\n
$> tshark<\/b> -P -i eth0<\/b> -f tcp -w \/tmp\/eth0.pcap<\/b><\/p>\n

$> tshark -x -r \/tmp\/eth0.pcap<\/b> | Menos<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Sa\u00edda criptografada, como mostrado abaixo -<\/strong>\u00a0<\/span><\/p>\n

\"\"<\/p>\n

Certificados rotativos<\/strong><\/p>\n

Como parte da higiene de seguran\u00e7a regular, espera-se que os certificados instalados sejam renovados periodicamente. Para garantir opera\u00e7\u00f5es cont\u00ednuas do cluster, o fluxo de trabalho compat\u00edvel seria desativar o modo de criptografia, carregar os certificados mais recentes em todos os n\u00f3s do cluster e ativar a criptografia novamente. A seguir, est\u00e3o os comandos que o administrador dever\u00e1 executar para alternar os certificados:<\/span>
\n<\/span>
\n<\/span>1. Verifique o n\u00edvel de criptografia do cluster -\u00a0<\/b><\/p>\n\n\n\n
.\/couchbase-cli <\/span>configura\u00e7\u00e3o de seguran\u00e7a<\/b> -get -c localhost:8091 -u -p<\/span><\/p>\n

{\"disableUIOverHttp\": false, \"disableUIOverHttps\": false, <\/span>\"clusterEncryptionLevel\": \"all\"}<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Se o n\u00edvel for \"all\", conforme mostrado, ser\u00e1 necess\u00e1rio alter\u00e1-lo para \"control\" usando o comando couchbase-cli setting-security set.<\/span><\/p>\n

    \n
  1. Desative a criptografia de cluster usando o comando \"change-cluster-encryption\" da CLI.<\/b><\/li>\n<\/ol>\n\n\n\n
