Ensure that host based authentication files are not present

高级别 2自动化aix

说明

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.

检查方式

审计方法: Shell 命令

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

预期输出: compliant

修复方式

修复方法: 操作指南或基础设施补丁

Remove the.rhosts and .netrc files from all user home directories: find / \( -fstype jfs -o -fstype jfs2 \) -name ".netrc" -exec rm {} \; find / \( -fstype jfs -o -fstype jfs2 \) -name ".rhosts" -exec rm {} \; find / \( -fstype jfs -o -fstype jfs2 \) -name ".shosts" -exec rm {} \;
