+# Résumé
+
+Effectuer des recherches de vulnérabilités et des mises à jour quotidiennes peut etre un fardeau pour un administrateur système.
+Afin d'éviter des interruptions systèmes dans un environnement de production, il est fréquent pour un administrateur système de choisir de ne pas utiliser la fonction de mise à jour automatique proposée par le gestionnaire de paquets et d'effecter ces mises à jour manuellement.
+Ce qui implique les problèmes suivants :
+- L'administrateur système devra surveiller constamment toutes les nouvelles vulnérabilités dans NVD (National Vulnerability Database) etc.
+- Il pourrait être impossible pour un administrateur système de surveiller tous les logiciels installés sur un serveur.
+- Il est coûteux d'effectuer une analyse pour déterminer quels sont les serveurs affectés par de nouvelles vulnérabilités. La possibilité de négliger un serveur ou deux est bien présente.
+
+Vuls est un outil crée pour palier aux problèmes listés ci-dessus. Voici ses caractéristiques.
+- Informer les utilisateurs des vulnérabilités système.
+- Informer les utilisateurs des systèmes concernés. 
+- La détection de vulnérabilités est effectuée automatiquement pour éviter toute négligence.
+- Les rapports sont générés régulièrement via CRON pour mieux gérer ces vulnérabilités.
+
+![Vuls-Motivation](img/vuls-motivation.png)
+
+----
+
+# Caractéristiques principales
+
+- Recherche de vulnérabilités sur des serveurs Linux
+    - Supporte Ubuntu, Debian, CentOS, Amazon Linux, RHEL
+    - Cloud, auto-hébergement, Docker
+- Scan d'intergiciels non inclus dans le gestionnaire de paquets de l'OS
+    - Scan d'intergiciels, de libraries de language de programmation et framework pour des vulnérabilités
+    - Supporte les logiciels inscrits au CPE
+- Architecture sans agent
+    - L'utilisateur doit seulement mettre en place VULS sur une seule machine qui se connectera aux autres via SSH
+- Génération automatique des fichiers de configuration
+    - Auto detection de serveurs via CIDR et génération de configuration
+- Email et notification Slack possibles (supporte le Japonais) 
+- Les résultats d'un scan sont accessibles dans un shell via TUI Viewer terminal.
+
+----
+
+# Ce que Vuls ne fait pas
+
+- Vuls ne met pas à jour les programmes affectés par les vulnérabilités découvertes.
+
+----
+
+# Hello Vuls 
+
+Ce tutoriel décrit la recherche de vulnérabilités sur une machine locale avec Vuls.
+Voici les étapes à suivre. 
+
+1. Démrarrage d'Amazon Linux
+1. Autoriser les connexions SSH depuis localhost
+1. Installation des prérequis
+1. Déploiement de go-cve-dictionary
+1. Deploiement de Vuls
+1. Configuration
+1. Préparation
+1. Scan
+1. TUI(Terminal-Based User Interface)
+
+## Step1. Démrarrage d'Amazon Linux
+
+- Nous utilisons dans cette exemple une vieille AMI (amzn-ami-hvm-2015.09.1.x86_64-gp2 - ami-383c1956)
+- Taille de l'instance : t2.medium
+    - La première fois, t2.medium et plus sont requis pour la récupération des CVE depuis NVD (2.3GB de mémoire utilisé)
+    - Une fois la récupération initiale des données NVD terminée vous pouvez passer sur une instance t2.nano.
+- Ajoutez la configuration suivante au cloud-init, afin d'éviter une mise à jour automatique lors du premier démarrage.
+
+    - [Q: How do I disable the automatic installation of critical and important security updates on initial launch?](https://aws.amazon.com/amazon-linux-ami/faqs/?nc1=h_ls)
+    ```
+    #cloud-config
+    repo_upgrade: none
+    ```
+
+## Step2. Paramètres SSH
+
+Il est obligatoire que le serveur puisse se connecter à son propre serveur SSH
+
+Générez une paire de clés SSH et ajoutez la clé publique dans le fichier authorized_keys
+```bash
+$ ssh-keygen -t rsa
+$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
+$ chmod 600 ~/.ssh/authorized_keys
+```
+
+## Step3. Installation des prérequis
+
+Vuls requiert l'installation des paquets suivants : 
+
+- sqlite
+- git
+- gcc
+- go v1.7.1 or later
+    - https://golang.org/doc/install
+
+```bash
+$ ssh ec2-user@52.100.100.100  -i ~/.ssh/private.pem
+$ sudo yum -y install sqlite git gcc
+$ wget https://storage.googleapis.com/golang/go1.7.1.linux-amd64.tar.gz
+$ sudo tar -C /usr/local -xzf go1.7.1.linux-amd64.tar.gz
+$ mkdir $HOME/go
+```
+Ajoutez les lignes suivantes dans /etc/profile.d/goenv.sh
+
+```bash
+export GOROOT=/usr/local/go
+export GOPATH=$HOME/go
+export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
+```
+
+Ajoutons ces nouvelles variables d’environnement au shell
+```bash
+$ source /etc/profile.d/goenv.sh
+```
+
+## Step4. Déploiement de [go-cve-dictionary](https://github.com/kotakanbe/go-cve-dictionary)
+
+go get
+
+```bash
+$ sudo mkdir /var/log/vuls
+$ sudo chown ec2-user /var/log/vuls
+$ sudo chmod 700 /var/log/vuls
+$ go get github.com/kotakanbe/go-cve-dictionary
+```
+
+Démarrez go-cve-dictionary en mode serveur.
+Lors de son premier démarrage go-cve-dictionary récupère la liste des vulnérabilités depuis NVD
+Cette opération prend environ 10 minutes (sur AWS).  
+
+## Step5. Déploiement de Vuls
+
+Ouvrez un second terminal, connectez vous à l'instance ec2 via SSH
+
+go get
+```
+$ go get github.com/future-architect/vuls
+```
+
+## Step6. Configuration
+
+Créez un fichier de configuration (TOML format).
+
+```
+$ cat config.toml
+[servers]
+
+[servers.172-31-4-82]
+host         = "172.31.4.82"
+port        = "22"
+user        = "ec2-user"
+keyPath     = "/home/ec2-user/.ssh/id_rsa"
+```
+
+## Step7. Configuration des serveurs cibles vuls  
+
+```
+$ vuls prepare
+```
+
+## Step8. Scan
+
+```
+$ vuls scan -cve-dictionary-dbpath=$PWD/cve.sqlite3
+INFO[0000] Begin scanning (config: /home/ec2-user/config.toml)
+

+
+# How to use this image
+
+1. fetch nvd (vuls/go-cve-dictionary)
+1. configuration (vuls/vuls)
+1. prepare (vuls/vuls)
+1. scan (vuls/vuls)
+1. vulsrepo (vuls/vulsrepo)
+
+## Step1. Fetch NVD
+
+```console
+$ for i in {2002..2016}; do \
+    docker run --rm -it \
+    -v $PWD:/vuls \
+    -v $PWD/go-cve-dictionary-log:/var/log/vuls \
+    vuls/go-cve-dictionary fetchnvd -years $i; \
+  done
+```
+
+## Step2. Configuration
+
+Create config.toml referring to [this](https://github.com/future-architect/vuls#configuration).
+
+```toml
+[servers]
+
+[servers.amazon]
+host         = "54.249.93.16"
+port        = "22"
+user        = "vuls-user"

+```
+　
+
+```console
+$ docker run --rm \

+    -v $PWD:/vuls \
+    -v $PWD/vuls-log:/var/log/vuls \
+    vuls/vuls configtest \
+    -config=./config.toml # path to config.toml in docker
+```
+
+## Step3. Prepare
+
+```console
+$ docker run --rm \
+    -v ~/.ssh:/root/.ssh:ro \
+    -v $PWD:/vuls \
+    -v $PWD/vuls-log:/var/log/vuls \
+    vuls/vuls prepare \
+    -config=./config.toml # path to config.toml in docker
+```
+
+## Step4. Scan
+
+```console
+$ docker run --rm -it \
+    -v ~/.ssh:/root/.ssh:ro \
+    -v $PWD:/vuls \
+    -v $PWD/vuls-log:/var/log/vuls \
+    -v /etc/localtime:/etc/localtime:ro \
+    -e "TZ=Asia/Tokyo" \
+    vuls/vuls scan \
+    -config=./config.toml # path to config.toml in docker
+```
+
+## Step5. Report
+
+```console
+$ docker run --rm -it \
+    -v ~/.ssh:/root/.ssh:ro \
+    -v $PWD:/vuls \
+    -v $PWD/vuls-log:/var/log/vuls \
+    -v /etc/localtime:/etc/localtime:ro \
+    vuls/vuls report \
+    -cvedb-path=/vuls/cve.sqlite3 \
+    -format-short-text \
+    -config=./config.toml # path to config.toml in docker
+```
+
+## Step6. vulsrepo
+
+```console
+$docker run -dt \
+    -v $PWD:/vuls \
+    -p 80:80 \
+    vuls/vulsrepo
+```
