Disclosed herein are system, method, and computer program product embodiments for securely performing a password change. An embodiment operates by receiving a password change request from a user. The password change request comprises an encrypted version of a new password for the user, a cleartext version of the new password, and a login name for the user. The embodiment then executes a command from a password rotator user account with the cleartext version of the new password, the encrypted version of the new password, and the login name. The embodiment then retrieves a public key associated with the login name. The embodiment then determines, based on the public key, that the password change request comes from the user and that the cleartext version of the new password has not been modified. The embodiment then sets the password of a user login associated with the user to the new password.

In one embodiment, a method includes determining at least one characteristic of a plurality of ports on an individual basis. The plurality of ports are hosted by a target system and configured to send and receive data. The method also includes creating port groupings, each port grouping including one or more of the plurality of ports. Ports are grouped together in a single port grouping based on at least one shared characteristic of individual ports in the single port grouping. In addition, the method includes receiving, from an initiator port, a target discovery request at a target port of the plurality of ports. Also, the method includes determining which particular port grouping the target port belongs to. Moreover, the method includes sending information about all ports in the particular port grouping to the initiator port in response to receiving the target discovery request from the initiator port.
