Ensure nis server services are not in use

높음레벨 1자동freebsd

설명

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 NIS generally has been replaced by such protocols as Lightweight Directory Access Protocol (LDAP).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.

점검 방법

감사 방식: 셸 명령

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"

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치
