# Observation des sessions de connexion

Notes de sécurité Active Directory pour l'observation des sessions de connexion, couvrant l'énumération, Kerberos, les identifiants, l'abus des ACL, le mouvement latéral, le flux de travail d'exploitation et les étapes de validation.

#### Outil LogonSessions

Pour voir les sessions de connexion présentes sur la machine, nous utilisons l’outil :

```bash
./logonsessions.exe
```

Cet outil vous permet d’observer les différentes sessions actives sur le système.

On peut voir, par exemple :

* une session utilisateur standard ;
* une session administrateur ;
* une session réseau ;
* une session de service.

#### Afficher les processus associés

Pour afficher les processus liés aux sessions de connexion :

```bash
./logonsessions.exe -p
```

Le `-p` L’option permet d’associer les processus aux sessions de connexion.

Cela aide à comprendre quels processus utilisent quel contexte de sécurité.

#### Exemple d’observation

Dans le laboratoire, lorsqu’un administrateur de domaine se connecte à un partage distant :

```bash
cd //WS01/c$
```

On peut observer une session du type :

```bash
Type de connexion : Réseau
Package d’authentification : Kerberos
```

Cela indique que l’accès réseau a été obtenu via Kerberos.

# 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://hacking-notes.jord4n.pro/fr/active-directory/credentials/logon-session-observation.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.
