Final answer:
To meet the requirement of encrypting network traffic to and from the RDS database instance hosted on AWS Cloud, you should configure your RDS database to enable encryption and use the profile credentials specific to your EC2 instance to access the database.
Step-by-step explanation:
To meet the requirement of encrypting network traffic to and from the RDS database instance hosted in the AWS Cloud, you need to configure your RDS database to enable encryption. This can be done by selecting the option to enable encryption when creating or modifying the RDS instance. By enabling encryption, the network traffic will be encrypted using SSL.
To ensure improved security, you can use the profile credentials specific to your EC2 instance to access the database instead of a password. This can be achieved by launching the mysql client using the --ssl-ca parameter when connecting to the database. This ensures that the client uses the SSL certificate along with your EC2 instance profile credentials to establish a secure connection.
