Your company has set up the AWS Managed Microsoft AD directory.
There are on-premises nodes that will be using the AWS Managed Microsoft AD directory for authentication.
You need to ensure that all traffic is encrypted in transit.
How can you achieve this in the most IDEAL manner?

This is mentioned in the AWS Documentation.
To mitigate this form of data exposure, AWS Managed Microsoft AD provides an option for you to enable LDAP over Secure Sockets Layer (SSL)/Transport Layer Security (TLS), also known as LDAPS.
With LDAPS, you can improve security across the wire and meet compliance requirements by encrypting all communications between your LDAP-enabled applications and AWS Managed Microsoft AD directory.
Since the ideal and correct approach is specified in the AWS Documentation, all other options are incorrect.

LDAP is a protocol that is commonly used for authentication and authorization purposes. LDAPS is a secure version of LDAP that uses the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocol to encrypt the data in transit between the client and the server.
Enabling LDAPS ensures that all traffic between the on-premises nodes and the AWS Managed Microsoft AD directory is encrypted and secure. This helps to protect against eavesdropping, data tampering, and other security threats.
The other options mentioned in the question, such as using KMS Keys to encrypt the traffic, enabling LDAP over HTTPS, and enabling server-side encryption, do not provide the same level of security as LDAPS.
Using KMS Keys to encrypt the traffic would only encrypt the data at rest, not during transit. Enabling LDAP over HTTPS is an option, but LDAPS is a better choice because it provides a stronger encryption protocol. Enabling server-side encryption would only encrypt the data at rest, not during transit.
In summary, the most ideal way to ensure that all traffic is encrypted in transit when using the AWS Managed Microsoft AD directory is to enable LDAP over SSL (LDAPS).
