# メモリ内資格情報へのアクセス: LSASS

メモリ内資格情報へのアクセス: LSASSのためのActive Directoryセキュリティノート。列挙、Kerberos、資格情報、ACL悪用、ラテラルムーブメント、攻撃のワークフロー、検証手順を扱う。

### LSASS とは何ですか？

**LSASS**や **ローカル セキュリティ機関サブシステム サービス**、重要な Windows プロセスです。

そのプロセスは次のとおりです:

```bash
lsass.exe
```

LSASS が特に管理するもの:

* ローカル認証;
* ユーザー セッション;
* トークン;
* 一部の資格情報;
* 認証メカニズムに必要なシークレット。

### なぜ LSASS は機密性が高いのか

攻撃者がマシン上で管理者権限を取得すると、LSASS のメモリへのアクセスを試みることができます。

ラボ環境では、メモリ内にどのような種類の情報が存在し得るかを理解できます。

設定によっては、次のものが見つかります:

* NTLM ハッシュ;
* Kerberos チケット;
* セッション情報;
* キャッシュされた資格情報;

## 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://hacking-notes.jord4n.pro/ja/active-directory/credentials/lsass-memory-credential-access.md?ask=<question>&goal=<user_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.
