The klogin daemon must be disabled on AIX.
Medium Severity
<VulnDiscussion>The klogin service offers a higher degree of security than traditional rlogin or telnet by eliminating most clear-text password exchanges on the network. However, it is still not as secure as SSH, which encrypts all traffic. If using klogin to log in to a system, the password is not sent in clear text; however, if using "su" to another user, that password exchange is open to detection from network-sniffing programs. The recommendation is to use SSH wherever possible instead of klogin. If the klogin service is used, use the latest Kerberos version available and make sure that all the latest patches are installed.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
