# 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。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
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 optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
