日志和监控
在实际开发中，有效的日志和监控系统可以帮助我们及时发现和响应安全事件：
安全日志记录：记录敏感操作和访问日志，以便在发生安全事件时可以追溯。importlogginglogger=logging.getLogger('security')logger.setLevel(logging.INFO)handler=logging.FileHandler('security.log')formatter=logging.Formatter('%(asctime)s-%(levelname)s-%(message)s')handler.setFormatter(formatter)logger.addHandler(handler)logger.info('Useraccessedsensitivedata')实时监控和告警：使用监控工具如Prometheus、Grafana进行实时监控，并?配置告警策略。
