🔍 Как установить сканер уязвимостей GVM на Ubuntu 20.04

GVM (Greenbone Vulnerability Management) – это решение с открытым исходным кодом для сканирования уязвимостей.

GVM ранее назывался OpenVAS.

Greenbone Vulnerability Manager и OpenVAS широко используются по всему миру, включая экспертов по безопасности и обычных пользователей.

В этой статье мы покажем, как установить и настроить GVM в Ubuntu 20.04, чтобы убедиться, что ваши серверы защищены от атак.

Базовая система

Мы настроим Greenbone Vulnerability Manager 20.08 с базовой установкой системных пакетов на Ubuntu 20.04.

Установим необходимые компоненты

Сначала установите следующие пакеты зависимостей.

sudo su -
apt update &&\
apt -y dist-upgrade &&\
apt -y autoremove &&\
apt install -y software-properties-common &&\
apt install -y build-essential cmake pkg-config libglib2.0-dev libgpgme-dev libgnutls28-dev uuid-dev libssh-gcrypt-dev libldap2-dev doxygen graphviz libradcli-dev libhiredis-dev libpcap-dev bison libksba-dev libsnmp-dev gcc-mingw-w64 heimdal-dev libpopt-dev xmltoman redis-server xsltproc libical-dev postgresql postgresql-contrib postgresql-server-dev-all gnutls-bin nmap rpm nsis curl wget fakeroot gnupg sshpass socat snmp smbclient libmicrohttpd-dev libxml2-dev python3-polib gettext rsync xml-twig-tools python3-paramiko python3-lxml python3-defusedxml python3-pip python3-psutil python3-impacket virtualenv vim git &&\
apt install -y texlive-latex-extra --no-install-recommends &&\
apt install -y texlive-fonts-recommended &&\
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - &&\
echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list &&\
apt update &&\
apt -y install yarn &&\
yarn install &&\
yarn upgrade

Создадим пользователя GVM

Вставьте следующие команды в терминал, чтобы создать пользователя gvm, который будет использоваться в процессе установки и компиляции:

echo 'export PATH="$PATH:/opt/gvm/bin:/opt/gvm/sbin:/opt/gvm/.local/bin"' | tee -a /etc/profile.d/gvm.sh &&\
chmod 0755 /etc/profile.d/gvm.sh &&\
source /etc/profile.d/gvm.sh &&\
bash -c 'cat < /etc/ld.so.conf.d/gvm.conf
# gmv libs location
/opt/gvm/lib
EOF'

mkdir /opt/gvm &&\
adduser gvm --disabled-password --home /opt/gvm/ --no-create-home --gecos '' &&\
usermod -aG redis gvm &&\
chown gvm:gvm /opt/gvm/

Теперь войдите от пользователя gvm.

sudo su - gvm

Скачаем и установим программное обеспечение (GVM)

mkdir src &&\
cd src &&\
export PKG_CONFIG_PATH=/opt/gvm/lib/pkgconfig:$PKG_CONFIG_PATH

git clone -b gvm-libs-20.08 --single-branch  https://github.com/greenbone/gvm-libs.git &&\
git clone -b openvas-20.08 --single-branch https://github.com/greenbone/openvas.git &&\
git clone -b gvmd-20.08 --single-branch https://github.com/greenbone/gvmd.git &&\
git clone -b master --single-branch https://github.com/greenbone/openvas-smb.git &&\
git clone -b gsa-20.08 --single-branch https://github.com/greenbone/gsa.git &&\
git clone -b ospd-openvas-20.08 --single-branch  https://github.com/greenbone/ospd-openvas.git &&\
git clone -b ospd-20.08 --single-branch https://github.com/greenbone/ospd.git

Установим gvm-libs (GVM)

cd gvm-libs &&\
export PKG_CONFIG_PATH=/opt/gvm/lib/pkgconfig:$PKG_CONFIG_PATH &&\
mkdir build &&\
cd build &&\
cmake -DCMAKE_INSTALL_PREFIX=/opt/gvm .. &&\
make &&\
make doc &&\
make install &&\
cd /opt/gvm/src

Установим openvas-smb (GVM)

cd openvas-smb &&\
export PKG_CONFIG_PATH=/opt/gvm/lib/pkgconfig:$PKG_CONFIG_PATH &&\
mkdir build &&\
cd build/ &&\
cmake -DCMAKE_INSTALL_PREFIX=/opt/gvm .. &&\
make &&\
make install &&\
cd /opt/gvm/src

Установим сканер (GVM)

Как и в предыдущих шагах, мы создадим и установим сканер openvas:

cd openvas &&\
export PKG_CONFIG_PATH=/opt/gvm/lib/pkgconfig:$PKG_CONFIG_PATH &&\
mkdir build &&\
cd build/ &&\
cmake -DCMAKE_INSTALL_PREFIX=/opt/gvm .. &&\
make &&\
make doc &&\
make install &&\
cd /opt/gvm/src

Настроим redis для установки OpenVAS (root)

Теперь мы должны выйти из текущего сеанса, чтобы вернуться к привилегированному пользователю, набрав «exit» в терминале.

Теперь вставьте в терминал следующий код:

export LC_ALL="C" &&\
ldconfig &&\
cp /etc/redis/redis.conf /etc/redis/redis.orig &&\
cp /opt/gvm/src/openvas/config/redis-openvas.conf /etc/redis/ &&\
chown redis:redis /etc/redis/redis-openvas.conf &&\
echo "db_address = /run/redis-openvas/redis.sock" > /opt/gvm/etc/openvas/openvas.conf &&\
systemctl enable redis-server@openvas.service &&\
systemctl start redis-server@openvas.service

sysctl -w net.core.somaxconn=1024 &&\
sysctl vm.overcommit_memory=1 &&\
echo "net.core.somaxconn=1024"  >> /etc/sysctl.conf &&\
echo "vm.overcommit_memory=1" >> /etc/sysctl.conf

cat << /etc/systemd/system/disable-thp.service
