Which options can secure OpenLDAP? (Select THREE correct choices)

Transport Layer Security (TLS) is a protocol designed to provide secure communication over a computer network, and it is widely used to protect sensitive data from eavesdropping and tampering. When securing OpenLDAP, using TLS ensures that the data transmitted between the LDAP client and server is encrypted, helping to prevent unauthorized access and protect user credentials during authentication processes.

Access Control Lists (ACLs) serve as a means to define permissions for users and groups within the OpenLDAP directory. They determine who can access which entries or attributes, thereby enforcing security at the application level. By configuring proper ACLs, administrators can restrict access effectively, ensuring that only authorized users can read or modify sensitive data stored in the directory.

Secure Sockets Layer (SSL) is the predecessor to TLS, and while it is largely phased out in favor of TLS due to security vulnerabilities, it provided similar capabilities in encrypting communication between clients and servers. In environments where SSL might still be utilized, it would also serve to secure OpenLDAP similarly by encrypting the data exchanged over the network.

These options collectively enhance the security of OpenLDAP through encryption and access management, addressing both data transit protection and user access control.
