What type of LDAP services has Alex configured when using ports 636 and 3269?

The configuration of using ports 636 and 3269 indicates that Alex has set up Secure LDAP services. Port 636 is specifically designated for LDAP over SSL (LDAPS), which provides a secure channel for transmitting data by encrypting the information exchanged between the LDAP client and server. This makes it resilient against eavesdropping and man-in-the-middle attacks, thus protecting sensitive directory data.

Port 3269 is used for Global Catalog queries over SSL. The Global Catalog is essential in Active Directory environments, providing a searchable, partial representation of every object in the directory, and using SSL ensures that these queries and results are also securely transmitted and protected from unauthorized interception.

The choice of these specific ports directly ties back to the practice of securing communications in directory services, thereby confirming that Secure LDAP is the appropriate classification of the services Alex has configured.
