TMA-AIX-4.3.4.29
Ensure tftpd daemon is not in use
HighLevel 1Automatedaix
Description
This entry starts the tftp service when required. The tftp service allows remote systems to download or upload files to the tftp server without any authentication. It is therefore a service that should not run, unless needed. 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=$(lssrc -s inetd -l 2>/dev/null | grep -c '[[:blank:]]tftp'); echo "$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 'tftp' -p 'udp6' refresh -s inetd
