Ensure all entries in /etc/hosts.equiv are removed

高级别 2自动化aix

说明

This process removes all entries from the /etc/hosts.equiv file. The /etc/hosts.equiv file can be used to circumvent normal login or change control procedures. The existence of this file, with the relevant entries, can allow remote user access to a system bypassing local user and password authentication. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

检查方式

shell

command -v grep >/dev/null 2>&1 || exit 1; out=$( { grep -Ev "^[[:blank:]]*(#|$)" /etc/hosts.equiv ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

预期输出: compliant
