在生产环境中部署像Gemma 3n这样的AI模型时，安全是至关重要的。无论你是为企业使用构建应用程序、处理敏感数据，还是部署面向公众的服务，理解并实施适当的安全措施都是必不可少的。
这个全面指南涵盖了Gemma 3n安全的所有方面，从数据保护和模型安全到部署安全和隐私合规。我们将提供实用的、可操作的建议，你可以立即实施来保护你的AI应用程序。
为什么AI模型的安全很重要
像Gemma 3n这样的AI模型提出了独特的安全挑战：
- 数据隐私：模型可以记忆并可能泄露敏感的训练数据
- 模型反转：攻击者可能试图从模型输出中提取训练数据
- 提示注入：恶意输入可以操纵模型行为
- 资源滥用：未经授权的访问可能导致成本超支
- 合规性：各种法规要求特定的安全措施
