Ensure netstat daemon is not in use

MediumLevel 1Automatedaix

Description

This entry executes the command netstat -f inet. This service is displays active IP connections on a server. The recommendation is to leave this disabled. The netstat command symbolically displays the contents of various network-related data structures for active connections. 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=$(lssrc -s inetd -l 2>/dev/null | grep -c 'netstat'); echo "$n"

Expected output: 0

How it is fixed

Fix method: Guidance or infrastructure patch

In /etc/inetd.conf, comment out the netstat entry: chsubserver -r inetd -C /etc/inetd.conf -d -v 'netstat' -p 'tcp' refresh -s inetd
