Best practices for securing network access to an instance
Access to VMs is protected by network-based access control mechanisms. Network-based access controls are the equivalent of the on-premises layer 4 network firewall or access control mechanism.
Network access refers to the action of connecting to a VM over the network and protecting it from unauthorized access using network access control lists (NACLs) (such as the on-prem firewall).
Network access controls work in one of the following ways:
- Stateless – The receiver (for example, a firewall) does not maintain the previous connection’s state (of the client). Suitable for scenarios that require high network speed. It requires the configuration of both inbound and outbound network rules.
- Stateful – The receiver (for example, a firewall) maintains the entire connection’s state (of the client). Suitable for scenarios where we need to maintain information about connections between a client...
