TMA-AIX-4.2.5

Ensure that host based authentication files are not present

高等級 2自動化aix

說明

This recommendation removes all instances of .rhosts, .shosts and .netrc files from the system. The .rhosts, .shosts and .netrc files can be used to circumvent normal login or change control procedures. The existence of such files, 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.

檢查方式

稽核方法: Shell 指令

shell

command -v find >/dev/null 2>&1 || exit 1; out=$( { find / \( -fstype jfs -o -fstype jfs2 \) \( -name .netrc -o -name .rhosts -o -name .shosts \) -print ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

預期輸出: compliant
