1.Difference in NACL and security hub?

Question

Accepted Answer

NACL and Security Hub are both AWS services, but they serve different purposes.

NACL (Network Access Control List) is a firewall that controls inbound and outbound traffic at the subnet level.
Security Hub is a security service that provides a comprehensive view of security alerts and compliance status across AWS accounts.
NACL operates at the network layer (Layer 3) of the OSI model, while Security Hub operates at the application layer (Layer 7).
NACL rules are stateless, meaning they apply to individual packets, while Security Hub analyzes security findings and events from various sources.
NACL is used to control traffic between subnets or between subnets and the internet, while Security Hub helps identify and prioritize security issues across AWS resources.

Accepted Answer

Security groups are tied to an instance whereas Network ACLs are tied to the subnet. Network ACLs are applicable at the subnet level, so any instance in the subnet with an associated NACL will follow rules of NACL. That's not the case with security groups, security groups has to be assigned explicitly to the instance.
