文件系统安全

文件权限

适当的文件权限对于安全至关重要。

权限指南

路径	权限	业主	原因
主文件.php	644	644根	包含数据库凭据
*.php 文件	644	644根	防止未经授权的修改
目录	755	755根	允许读取，阻止写入
缓存/	777	777 www-data	Web服务器必须写
模板_c/	777	777 www-data	编译模板
上传/	777	777 www-data	用户上传
变量/	777	777 www-data	可变数据
安装/	删除	-	安装后删除
配置/	755	755根	可读，不可写

设置权限脚本

/usr/local/bin/xoops-secure.sh

#!/bin/bash
XOOPS_PATH="/var/www/html/xoops"
WEB_USER="www-data"

# Set ownership
echo "Setting ownership..."
chown -R $WEB_USER:$WEB_USER $XOOPS_PATH

# Set restrictive default permissions
echo "Setting base permissions..."
find $XOOPS_PATH -type d -exec chmod 755 {} \;
find $XOOPS_PATH -type f -exec chmod 644 {} \;

# Make specific directories writable
echo "Setting writable directories..."
chmod 777 $XOOPS_PATH/cache
chmod 777 $XOOPS_PATH/templates_c
chmod 777 $XOOPS_PATH/uploads
chmod 777 $XOOPS_PATH/var

# Protect sensitive files
echo "Protecting sensitive files..."
chmod 644 $XOOPS_PATH/mainfile.php
chmod 444 $XOOPS_PATH/mainfile.php.dist  # If it exists (read-only)

# Verify permissions
echo "Verifying permissions..."
ls -la $XOOPS_PATH | grep -E "mainfile|cache|uploads|var|templates_c"

echo "Security hardening completed!"

运行脚本：

chmod +x /usr/local/bin/xoops-secure.sh
/usr/local/bin/xoops-secure.sh

删除安装文件夹

CRITICAL: 安装后必须删除安装文件夹！

# Option 1: Delete completely
rm -rf /var/www/html/xoops/install/

# Option 2: Rename and keep for reference
mv /var/www/html/xoops/install/ /var/www/html/xoops/install.bak/

# Verify removal
ls -la /var/www/html/xoops/ | grep install

保护敏感目录

创建 .htaccess 文件以阻止对敏感文件夹的 Web 访问：

文件：/var/www/html/XOOPS/var/.htaccess

<FilesMatch "\.(php|phtml|php3|php4|php5|php6|php7|phps|pht|phar)$">
    Deny from all
</FilesMatch>

<IfModule mod_autoindex.c>
    Options -Indexes
</IfModule>

文件：/var/www/html/XOOPS/templates_c/.htaccess

<FilesMatch "\.(php|phtml|php3|php4|php5|php6|php7|phps|pht|phar)$">
    Deny from all
</FilesMatch>

Options -Indexes

文件：/var/www/html/XOOPS/cache/.htaccess

Options -Indexes
<FilesMatch "\.(php|phtml|php3|php4|php5|php6|php7)$">
    Deny from all
</FilesMatch>

保护上传目录

防止在上传中执行脚本：

文件：/var/www/html/XOOPS/uploads/.htaccess

# Prevent script execution
<FilesMatch "\.(php|phtml|php3|php4|php5|php6|php7|phps|pht|phar|pl|py|jsp|asp|aspx|cgi|sh|bat|exe)$">
    Deny from all
</FilesMatch>

# Prevent directory listing
Options -Indexes

# Additional protection
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /xoops/uploads/

    # Block suspicious files
    RewriteCond %{REQUEST_URI} \.(php|phtml|php3|php4|php5|php6|php7)$ [NC]
    RewriteRule ^.*$ - [F,L]
</IfModule>

SSL/HTTPS 配置

加密用户和服务器之间的所有流量。

获得SSL证书

选项 1：Let’s Encrypt 的免费证书

# Install Certbot
apt-get install certbot python3-certbot-apache

# Obtain certificate (auto-configures Apache)
certbot certonly --apache -d your-domain.com -d www.your-domain.com

# Verify certificate installed
ls /etc/letsencrypt/live/your-domain.com/

选项 2：商业 SSL 证书

联系SSL提供商或注册商：

1. 购买SSL证书
2. 验证域名所有权 3.在服务器上安装证书文件 4.配置网络服务器

Apache SSL 配置

创建HTTPS虚拟主机：

文件：/etc/apache2/sites-available/XOOPS-ssl.conf

<VirtualHost *:443>
    ServerName your-domain.com
    ServerAlias www.your-domain.com
    DocumentRoot /var/www/html/xoops

    # SSL Configuration
    SSLEngine on
    SSLProtocol TLSv1.2 TLSv1.3
    SSLCipherSuite HIGH:!aNULL:!MD5
    SSLCertificateFile /etc/letsencrypt/live/your-domain.com/cert.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/your-domain.com/privkey.pem
    SSLCertificateChainFile /etc/letsencrypt/live/your-domain.com/chain.pem

    # Security Headers
    Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
    Header always set X-Content-Type-Options "nosniff"
    Header always set X-Frame-Options "SAMEORIGIN"
    Header always set X-XSS-Protection "1; mode=block"
    Header always set Referrer-Policy "no-referrer-when-downgrade"
    Header always set Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'"

    <Directory /var/www/html/xoops>
        Options -Indexes +FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    # Restrict install folder
    <Directory /var/www/html/xoops/install>
        Deny from all
    </Directory>

    # Logging
    ErrorLog ${APACHE_LOG_DIR}/xoops_ssl_error.log
    CustomLog ${APACHE_LOG_DIR}/xoops_ssl_access.log combined
</VirtualHost>

# Redirect HTTP to HTTPS
<VirtualHost *:80>
    ServerName your-domain.com
    ServerAlias www.your-domain.com
    Redirect 301 / https://your-domain.com/
</VirtualHost>

启用配置：

# Enable SSL module
a2enmod ssl

# Enable site
a2ensite xoops-ssl

# Disable non-SSL site if exists
a2dissite 000-default

# Test configuration
apache2ctl configtest
# Should output: Syntax OK

# Restart Apache
systemctl restart apache2

Nginx SSL 配置

文件：/etc/nginx/sites-available/XOOPS

# HTTP to HTTPS redirect
server {
    listen 80;
    listen [::]:80;
    server_name your-domain.com www.your-domain.com;

    location / {
        return 301 https://$server_name$request_uri;
    }
}

# HTTPS server
server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name your-domain.com www.your-domain.com;
    root /var/www/html/xoops;
    index index.php index.html;

    # SSL Certificate Configuration
    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;

    # Modern SSL Configuration
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers on;
    ssl_session_cache shared:SSL:10m;
    ssl_session_timeout 10m;

    # HSTS Header
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;

    # Security Headers
    add_header X-Content-Type-Options "nosniff" always;
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-XSS-Protection "1; mode=block" always;
    add_header Referrer-Policy "no-referrer-when-downgrade" always;
    add_header Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'" always;

    # Restrict install folder
    location ~ ^/(install|upgrade)/ {
        deny all;
    }

    # Deny access to sensitive files
    location ~ /\. {
        deny all;
    }

    # PHP-FPM backend
    location ~ \.php$ {
        fastcgi_pass unix:/run/php-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    # Static files caching
    location ~* \.(js|css|png|jpg|gif|ico|svg)$ {
        expires 30d;
        add_header Cache-Control "public, immutable";
    }

    # URL rewriting
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    # Logging
    access_log /var/log/nginx/xoops_access.log;
    error_log /var/log/nginx/xoops_error.log;
}

启用配置：

ln -s /etc/nginx/sites-available/xoops /etc/nginx/sites-enabled/
nginx -t
systemctl restart nginx

验证HTTPS安装

# Test SSL configuration
openssl s_client -connect your-domain.com:443 -tls1_2

# Check certificate validity
openssl x509 -in /etc/letsencrypt/live/your-domain.com/cert.pem -noout -text

# SSL/TLS test online
# https://www.ssllabs.com/ssltest/
# https://www.testssl.sh/

Auto-Renew 让我们加密证书

# Enable auto-renewal
systemctl enable certbot.timer
systemctl start certbot.timer

# Test renewal process
certbot renew --dry-run

# Manual renewal if needed
certbot renew --force-renewal

Web 应用程序安全

防止SQL注射

XOOPS 使用参数化查询（默认情况下安全），但始终：

// UNSAFE - Never do this!
$query = "SELECT * FROM users WHERE name = '" . $_GET['name'] . "'";

// SAFE - Use prepared statements
$database = XoopsDatabaseFactory::getDatabaseConnection();
$sql = "SELECT * FROM " . $database->prefix('users') . " WHERE name = ?";
$result = $database->query($sql, array($_GET['name']));

交叉-Site脚本（XSS）预防

始终清理用户输入：

// UNSAFE
echo $_GET['user_input'];

// SAFE - Use XOOPS sanitization functions
echo htmlspecialchars($_GET['user_input'], ENT_QUOTES, 'UTF-8');

// Or use XOOPS functions
$text_sanitizer = new xoops_text_sanitizer();
echo $text_sanitizer->stripSlashesGPC($_GET['user_input']);

Cross-Site 请求伪造 (CSRF) 预防

XOOPS 包括 CSRF 令牌保护。始终包含令牌：

<!-- In forms -->
<form method="post">
    {xoops_token form=update}
    <input type="text" name="field">
    <input type="submit">
</form>

禁用上传文件夹中的PHP执行

防止攻击者上传并执行PHP：

# Create .htaccess in uploads folder
cat > /var/www/html/xoops/uploads/.htaccess << 'EOF'
<FilesMatch "\.(php|phtml|php3|php4|php5|php6|php7)$">
    Deny from all
</FilesMatch>
php_flag engine off
EOF

# Alternative: Disable execution globally in uploads
chmod 444 /var/www/html/xoops/uploads/  # Read-only

安全标头

配置重要的HTTP安全标头：

# Strict-Transport-Security (HSTS)
# Forces HTTPS for 1 year
Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"

# X-Content-Type-Options
# Prevents MIME type sniffing
Header always set X-Content-Type-Options "nosniff"

# X-Frame-Options
# Prevents clickjacking attacks
Header always set X-Frame-Options "SAMEORIGIN"

# X-XSS-Protection
# Browser XSS protection
Header always set X-XSS-Protection "1; mode=block"

# Referrer-Policy
# Controls referrer information
Header always set Referrer-Policy "strict-origin-when-cross-origin"

# Content-Security-Policy
# Controls resource loading
Header always set Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'; img-src 'self' data: https:; font-src 'self'"

管理面板安全

重命名管理文件夹

通过重命名来保护管理文件夹：

# Rename admin folder
mv /var/www/html/xoops/admin /var/www/html/xoops/myadmin123

# Update admin access URL
# Old: http://your-domain.com/xoops/admin/
# New: http://your-domain.com/xoops/myadmin123/

配置XOOPS以使用重命名的文件夹：

编辑主文件。php：

// Change this line
define('XOOPS_ADMIN_PATH', '/var/www/html/xoops/myadmin123');

管理员 IP 白名单限制管理员访问特定 IP：

文件：/var/www/html/XOOPS/myadmin123/.htaccess

# Allow only specific IPs
<RequireAll>
    Require ip 192.168.1.100   # Your office IP
    Require ip 203.0.113.50    # Your home IP
    Deny from all
</RequireAll>

或者使用 Apache 2.2：

Order Deny,Allow
Deny from all
Allow from 192.168.1.100 203.0.113.50

强大的管理员凭据

为管理员强制使用强密码：

1. 至少使用16个字符
2. 混合大写、小写、数字、符号 3.定期更改密码（每90天） 4.使用密码管理器
3. 启用两个-factor身份验证（如果可用）

监控管理员活动

启用管理员登录日志记录：

管理面板 > 系统 > 首选项 > 用户设置

Log Admin Logins: Yes
Log Failed Login Attempts: Yes
Alert Email on Admin Login: Yes

定期查看日志：

# Check database for login attempts
mysql -u xoops_user -p xoops_db << EOF
SELECT uid, uname, DATE_FROM_UNIXTIME(user_lastlogin) as last_login
FROM xoops_users WHERE uid = 1;
EOF

定期维护

更新XOOPS和模区块

保持XOOPS和所有模区块更新：

# Check for updates in admin panel
# Admin > Modules > Check for Updates

# Or via command line
cd /var/www/html/xoops
# Download and install latest version
# Follow upgrade guide

自动安全扫描

#!/bin/bash
# Security audit script

# Check file permissions
echo "Checking file permissions..."
find /var/www/html/xoops -type f ! -perm 644 ! -name "*.htaccess" | head -10

# Check for suspicious files
echo "Checking for suspicious files..."
find /var/www/html/xoops -type f -name "*.php" -newer /var/www/html/xoops/install/ 2>/dev/null

# Check database for suspicious activity
echo "Checking for failed login attempts..."
mysql -u xoops_user -p xoops_db << EOF
SELECT count(*) as attempts FROM xoops_audittrail WHERE action LIKE '%login%' AND status = 0;
EOF

定期备份

自动执行每日备份：

#!/bin/bash
# Daily backup script

BACKUP_DIR="/backups/xoops"
RETENTION=30  # Keep 30 days

# Backup database
mysqldump -u xoops_user -p xoops_db | gzip > $BACKUP_DIR/db_$(date +%Y%m%d).sql.gz

# Backup files
tar -czf $BACKUP_DIR/files_$(date +%Y%m%d).tar.gz /var/www/html/xoops --exclude=cache --exclude=templates_c

# Remove old backups
find $BACKUP_DIR -type f -mtime +$RETENTION -delete

echo "Backup completed at $(date)"

使用 cron 进行计划：

# Edit crontab
crontab -e

# Add line (runs daily at 2 AM)
0 2 * * * /usr/local/bin/xoops-backup.sh >> /var/log/xoops_backup.log 2>&1
