Ensure Only the Necessary SELinux Booleans are Enabled

낮음레벨 2자동bind

설명

SELinux booleans allow or disallow specific behaviors. There are two boolean variables specific to the ISC BIND DNS server: ; named_tcp_bind_http_port - Allow named to tcp bind http port ; named_write_master_zones - Allow named to write master zones The named_tcp_bind_http_port would allow enabling the BIND statistics http channel which is not recommended. The audit runs getsebool named_tcp_bind_http_port and requires off (named_write_master_zones is not audited).

점검 방법

감사 방식: 셸 명령

shell

v=$(getsebool named_tcp_bind_http_port 2>/dev/null) || exit 1
case "$v" in *'--> off') echo compliant ;; *) echo "$v" ;; esac

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

Perform the following to implement the recommended state: Disable the SELinux boolean using the setsebool command as shown below with the -P option to make the change persistent. # setsebool -P named_tcp_bind_http_port off
