Ensure shell daemon is not in use
MediumLevel 1Automatedaix
Description
This entry starts the rshd daemon when required. This daemon executes a command from a remote system. This shell service is used to execute a command from a remote server. The username and passwords are passed over the network in clear text and therefore insecurely. Unless required the rshd daemon will be disabled. 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=$(lssrc -s inetd -l 2>/dev/null | grep -c '[[:blank:]]shell'); echo "$n"- Expected output
0
How it is fixed
Fix method: Guidance or infrastructure patch
Use chsubserver to disable this service in /etc/inetd.conf: chsubserver -r inetd -C /etc/inetd.conf -d -v 'shell' -p 'tcp6' refresh -s inetd
