AWS EC2 instance allows public ingress access on Redis port 6379

Description

Redis is a caching service to store application related information which is sensitive and confidential. Allowing inbound traffic from external IPv4 addresses to the Redis ports can lead to attacks like DoS, Brute Force, Smurf, and reconnaissance. It is a best practice to block public access, restrict the inbound traffic from specific addresses and make the connection secure.
