Description: A network ACL is an optional security layer for your VPC that acts as a firewall to control traffic in and out of one or more subnets. Network ACLs allow you to define rules that determine what traffic is allowed or denied based on criteria such as IP addresses, protocols, and ports. These access control lists are essential for protecting cloud resources, as they provide granular control over network traffic. Unlike security groups, which are specific to instances, network ACLs are applied at the subnet level, meaning they affect all resources within that subnet. This provides an additional layer of security, allowing administrators to manage access more effectively. ACLs can be configured to allow or deny inbound and outbound traffic and can be used in conjunction with other cloud security tools to create a robust and secure network architecture. Their flexibility and customization capabilities make them a popular choice for businesses looking to protect their data and applications in a public cloud environment.<\/p>\n","protected":false},"excerpt":{"rendered":"
