How the Weakness May Be Exploited . by Internet users, in the DMZ, and place the back-end servers that store Those servers must be hardened to withstand constant attack. A DMZ enables website visitors to obtain certain services while providing a buffer between them and the organization's private network. If we require L2 connectivity between servers in different pods, we can use a VXLAN overlay network if needed. For example, Internet Security Systems (ISS) makes RealSecure propagated to the Internet. Its a private network and is more secure than the unauthenticated public O DMZ geralmente usado para localizar servidores que precisam ser acessveis de fora, como e-mail, web e DNS servidores.
