Rlogin is a software utility for Unix-like computer operating systems that allows users to log in on another host via a network, communicating via TCP port 513. Rlogin is most commonly deployed on corporate or academic networks, where user account information is shared between all the Unix machines on the network (often using NIS). But rlogin does have serious security problems. Please list rlogin's possible security problems.

Use the vulnerability database available on www.securityfocus.com/vulnerabilities to research three common vulnerabilities associated with the rlogin application. Next, write at least a two page paper in current APA format that lists each of vulnerabilities you discovered, how they affect the targeted systems, actions that can be taken to secure the systems, and provide information on an alternate application that can be used instead of rhost, if one is available.
