Amazon EMR has introduced a new account level configuration called Block Public Access to help administrators secure their EMR clusters from unrestricted public-network access. You can enable this configuration and prevent your account users from launching clusters with security group rules that open ports for inbound traffic from IPv4 0.0.0.0/0 or IPv6 ::/0. You can configure exceptions in Block Public access configuration to allow public access on a port or range of ports before you launch EMR clusters. Please visit Using Amazon EMR Block Public Access configuration to learn more.
This feature is available now in the US East (N.Virgina and Ohio), US West (N.California and Oregon), Canada (Central), EU(Frankfurt, Ireland, London, Paris and Stockholm), Asia Pacific (Mumbai, Seoul, Singapore, Sydney, and Tokyo), and South America (Sao Paulo) regions.
