difference between NACL and security group?

Question

Accepted Answer

NACL is a stateless firewall that controls traffic at the subnet level, while security groups are stateful firewalls that control traffic at the instance level.

NACL operates at the subnet level, while security groups operate at the instance level.
NACL is stateless, meaning it does not keep track of the state of connections, while security groups are stateful and keep track of connections.
NACL rules are evaluated in order, with the first rule that matches being applied, while security group rules are evaluated independently and all rules that apply are enforced.
NACL can be used to block specific IP addresses or ranges, while security groups are used to allow or deny traffic based on port and protocol.
Example: NACL can be used to block all traffic from a specific IP range to a subnet, while a security group can be used to allow SSH traffic to an instance.
