Ensure klogin daemon is not in use

MediumLevel 1Automatedaix

Description

This entry starts the klogin service when required. This is a kerberized login service, which provides a higher degree of security over traditional rlogin and telnet. 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. Audit: `lssrc -s inetd -l` must not list the service (count 0).

How it is checked

Audit method: Shell command

shell

command -v lssrc >/dev/null 2>&1 || exit 1; n=$(lssrc -s inetd -l 2>/dev/null | grep -c 'klogin'); echo "$n"

Expected output: 0

How it is fixed

Fix method: Guidance or infrastructure patch

In /etc/inetd.conf, comment out the klogin entry and refresh the inetd process: chsubserver -r inetd -C /etc/inetd.conf -d -v 'klogin' -p tcp lssrc -s inetd && refresh -s inetd
