我遵循了wiki.ubuntuusers.de上的官方文档，但我的 test.php 文件仍然允许恶意访问，例如 test.php?secret_file=my/secret/file.txt。想法为什么？
测试.php：
<?php
$secret_file = $_GET['secret_file'];
include ( $secret_file);
?>
test.php?secret_file=my/secret/file.txt 的预期结果是 HTTP 403 -access denied，但我的 Web 服务器仍然显示包含文件的内容。
我的安装步骤：
sudo apt-get install libapache2-mod-security2
sudo a2enmod security2
sudo a2enmod headers
Configuration
sudo cp /etc/modsecurity/modsecurity.conf-recommended /etc/modsecurity/modsecurity.conf
# Enable ModSecurity, attaching it to every transaction. Use detection
# only to start with, because that minimises the chances of post-installation
# disruption.
#
#SecRuleEngine DetectionOnly
#
SecRuleEngine On
Include /usr/share/modsecurity-crs/*.conf
Include /usr/share/modsecurity-crs/base_rules/*.conf
Include /usr/share/modsecurity-crs/optional_rules/*.conf
SecDebugLog /var/log/apache2/modsec_debug.log
SecDebugLogLevel 5
sudo service apache2 restart
sudo service apache2 force-reload
这是我的 modsec_debug.log 文件：modsec_debug.log
当我调用恶意 test.php?secret_file=my/secret/file.txt 它说：
