Protegendo Seu Ambiente OCS

Um dos pontos importantes da implementação do Office Communications Server é garantir que o sistema esteja seguro.

A própria estrutura do OCS já mantem uma segurança de alto nível, um exemplo disso é que todo o tráfego entre servidores e clientes é criptografado. Entretanto também é necessário atentarmos ao sistema operacional, este também deve ser customizado para minimizarmos ao máximo as vulnerabilidades do ambiente.

Para isso, segue abaixo uma tabela com todos os serviços que o OCS é dependente, qualquer outro serviço que não esteja listado abaixo pode ser desabilitado.
