Which of the following is correct in regards to those security groups?
A security group that has no ports open to your network.
A security group that has only port 3389 (for RDP) open to your network.
A security group that has only port 22 (for SSH) open to your network.
A security group that has port 22 (for SSH) or port 3389 (for RDP) open to your network.
Explanations:
AWS CloudHSM does not require specific ports like RDP or SSH to be open. It requires other ports related to cryptographic operations, not remote access.
Port 3389 is for RDP, which is typically used for remote desktop access. This is not relevant to the secure operation of CloudHSM.
Port 22 is for SSH, used for remote access. AWS CloudHSM does not require SSH access for its normal operation.
AWS CloudHSM requires specific ports to be open, and port 22 or 3389 are typically used for initial access or management. However, these are not the main ports needed for the cryptographic operations themselves.
I gauge that the answer is:
A security group that has port 22 (for SSH) or port 3389 (for RDP) open to your network.
