The first statement is correct: Security can be set through passwords, kerberos tickets, or certificates. The second statement is partially correct as it mentions passwords, Kerberos, and certificates, but also claims EC2 AMIs are controlled by them; however, EC2 instance access is controlled by security groups and IAM, not directly by Kerberos and X.509 certificates for user authentication. The third statement is incorrect, as AWS offers a wide variety of Amazon Machine Images (AMIs) for different Linux distributions, not just Red Hat.
