# Security 安全
本节介绍 BIOS 中与系统安全相关的设置选项，包括管理员密码、用户密码、安全启动、TPM（可信平台模块）等重要安全功能。
参见：华硕. 如何设置或解决忘记 BIOS 密码/UEFI 密码/开机密码\[EB/OL]. \[2026-03-26]. 。提供 BIOS/UEFI 密码设置与重置的详细指导。
参见：UEFI Forum. UEFI Specification\[EB/OL]. \[2026-04-17]. 。UEFI 规范是安全启动、密钥管理和平台安全机制的权威技术标准。
BIOS（基本输入输出系统，Basic Input/Output System）密码是一种固件层面的安全功能，用于阻止计算机在预启动阶段遭到未经授权的访问。BIOS 密码也常被称为系统设置密码、UEFI 密码、开机密码或安全密码。
当设备启动时，系统会提示用户输入 BIOS 密码，只有在输入正确密码后，才能访问和修改 BIOS 设置，并进入操作系统。这提供了一层额外的物理安全屏障，防止未经授权的人员更改硬件配置或篡改启动流程。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://book.bsdcn.org/bios/security-an-quan.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
