Ensure nis server services are not in use

Опис

The Network Information Service (NIS), formerly known as Yellow Pages, is a client- server directory service protocol used to distribute system configuration files. The NIS client ( ypbind ) was used to bind a machine to an NIS server and receive the distributed configuration files. The NIS service is inherently an insecure system that has been vulnerable to DOS attacks, buffer overflows and has poor authentication for querying NIS maps. NIS generally has been replaced by such protocols as Lightweight Directory Access Protocol (LDAP). Audit: rc.conf (sysrc) must not enable nis_server_enable.

Како се проверава

Метод провере: Команда љуске

shell

command -v sysrc >/dev/null 2>&1 || exit 1; r=compliant; for k in nis_server_enable; do v=$(sysrc -q -n $k 2>/dev/null); case "$v" in [Yy][Ee][Ss]|[Tt][Rr][Uu][Ee]|[Oo][Nn]|1) r="$k=$v";; esac; done; echo "$r"

Очекивани излаз: compliant

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

sysrc nis_server_enable="NO"; then stop the service (service <name> onestop)
