一键部署OpenClaw 网站上线后就会被扫描，被扫到漏洞就被打。 The suspected case is reported to have been a 22-year-old who died on Saturday and could be the country's first monkeypox fatality.,"The youth had no symptoms of monkeypox. He had been admitted to the hospital with symptoms of encephalitis and fatigue. His relatives handed over the test result only on Saturday. A high-level probe would be held into the death as monkeypox has a very low fatality rate," the minister said, as quoted by the Indian Express.,According to the newspaper's source, the young man was tested in the United Arab Emirates prior to boarding the flight to Kerala earlier in the month. The Indian Express also reported that he was buried in accordance with the monkeypox victim protocol and all of his primary contacts are under observation.,On July 23, the World Health Organization declared the monkeypox outbreak an international public health emergency. Over 22,000 cases have been reported worldwide in more than 70 countries.。安全防护不是一次性工作，而是持续的基本功。 先说SQL注入。最常见的攻击方式，黑客通过表单输入拼接SQL语句。防护方法很简单：用参数化查询，干掉字符串拼接。 # PHP防SQL注入写法（PDO参数化查询） // 错误写法：直接拼接字符串 $sql = "SELECT * FROM users WHERE name='" . $_POST['name'] . "'"; // 正确写法：使用PDO预处理 $stmt = $pdo->prepare("SELECT * FROM users WHERE name = :name"); $stmt->execute([':name' => $_POST['name']]); $result = $stmt->fetchAll(); 再说CC攻击。某个IP频繁请求你的页面，把服务器资源耗尽。
B | Nginx可以限制单IP请求频率。
C | # Nginx限制单IP请求频率（nginx.conf） http { limit_req_zone $binary_remote_addr zone=one:10m rate=10r/s; server { location / { limit_req zone=one burst=20 nodelay; # 每秒最多10个请求，突发允许20个 } } } # 封禁恶意User-Agent if ($http_user_agent ~* "bot|spider|crawler") { return 403; } DDoS防护个人站长很难自己搞，最好的办法是接CDN。Cloudflare免费版就能挡住大部分小规模DDoS。如果被打得很狠，就开CDN的“我被攻击了”模式，所有流量走CDN审查。 另外几个基本操作：后台目录加密码保护、数据库定期备份、程序及时更新打补丁。这些眠得快，别等被打了才想起来。
