Establishing an encrypted Virtual Private Cloud (VPC) in AWS is vital to safeguard the cloud resources. It starts by creating an VPC that is logically isolated from your cloud environment. This involves selecting a suitable CIDR block in order to make sure that the that the IP address space is adequate, and avoiding clashes with different networks. After the VPC is established it is essential to define subnets and ensure that you distinguish the private and public subnets. Public subnets are for access by external parties while private subnets safeguard internal resources.

NACLs serve as stateless firewalls that filter traffic at the subnet-level, while security groups offer stateful traffic filtering at an individual level. It is essential to set these rules so that they permit only the required outbound and inbound traffic. For instance, subnets that are private subnets are not allowed to be able to access the internet directly; this is managed by the NAT gateway that permits outgoing traffic, while blocking unwelcome inbound traffic.
Furthermore, VPC peering, or AWS Transit Gateway, you can secure connect several VPCs with no routing of traffic through the internet. Another crucial security step is the ability to create VPC flow logs. These give visibility into network traffic to monitor and audit purposes.
To protect yourself further, you can use AWS Identity and Access Management (IAM) policies to manage access for the VPC as well as its resource. Consider the possibility of encrypting your data during transit and in rest with AWS services such as KMS (Key Management Service). Combining these two actions, you can make an extremely secure and robust VPC that protects any cloud-based infrastructure.
