RUNBOOK Identificação de vulnerabilidades com OpenVAS

Analisar vulnerabilidades com OpenVAS (Open Vulnerability Assessment System)

O que é

O OpenVAS (Open Vulnerability Assessment System) é uma ferramenta de código aberto para análise de vulnerabilidades de segurança. Ele realiza a varredura em sistemas e redes para identificar possíveis falhas de segurança e gerar relatórios detalhados sobre os riscos encontrados.

Por que usar

1. Detecção de vulnerabilidades: Identifica falhas de segurança em sistemas, aplicações e redes.
2. Relatórios detalhados: Fornece informações sobre as vulnerabilidades encontradas e suas possíveis consequências.
3. Código aberto: Sem custo de licença, podendo ser personalizado conforme a necessidade.
4. Compatibilidade: Suporta uma ampla gama de protocolos e sistemas operacionais.

Instalação

O OpenVAS pode ser implantado usando Docker, o que facilita a configuração e a manutenção.

Instalação do Docker

curl -sSL https://get.docker.com/ | sh 

systemctl start docker

systemctl enable docker

Instalação do compose.

curl -L "https://github.com/docker/compose/releases/download/v2.12.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && \
chmod +x /usr/local/bin/docker-compose 

Greenbone

mkdir /srv/openvas && cd /srv/openvas && touch docker-compose.yml

• Copie o código a seguir e adicione no arquivo docker-compose.yml

• Baixe as imagens do docker

docker-compose pull 

• Execute o container

docker-compose up -d 

Caso prefira um script com todos os comandos:

cd /srv/openvas && touch scripts.sh
