Cyber Security: Wazuh Agent Install

Deploying Wazuh agents on Linux endpoints

Agent run di host yang ingin Anda pantau dan berkomunikasi dengan server Wazuh, mengirimkan data hampir secara real-time melalui saluran terenkripsi dan diautentikasi.

Penerapan agent Wazuh pada sistem Linux menggunakan variabel penerapan yang memfasilitasi tugas penginstalan, pendaftaran, dan konfigurasi agen. Atau, jika Anda ingin mengunduh langsung paket agen Wazuh, lihat bagian daftar packages https://documentation.wazuh.com/current/installation-guide/packages-list.html

Catatan Anda memerlukan hak pengguna root untuk menjalankan semua perintah yang dijelaskan di bawah ini.

Add the Wazuh repository

Add the Wazuh repository to download the official packages.

Install the GPG key:

curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | gpg --no-default-keyring --keyring gnupg-ring:/usr/share/keyrings/wazuh.gpg --import && chmod 644 /usr/share/keyrings/wazuh.gpg

Add the repository:

echo "deb [signed-by=/usr/share/keyrings/wazuh.gpg] https://packages.wazuh.com/4.x/apt/ stable main" | tee -a /etc/apt/sources.list.d/wazuh.list

Update the package information:

apt-get update

Note

For Debian 7, 8, and Ubuntu 14 systems import the GCP key and add the Wazuh repository (steps 1 and 2) using the following commands.

apt-get install gnupg apt-transport-https
curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | apt-key add -

echo "deb https://packages.wazuh.com/4.x/apt/ stable main" | tee -a /etc/apt/sources.list.d/wazuh.list

Deploy a Wazuh agent

To deploy the Wazuh agent on your endpoint, select your package manager and edit the WAZUH_MANAGER variable to contain your Wazuh manager IP address or hostname.

WAZUH_MANAGER="10.0.0.2" apt-get install wazuh-agent

For additional deployment options such as agent name, agent group, and registration password, see the Deployment variables for Linux section.

Note Alternatively, if you want to install an agent without registering it, omit the deployment variables. To learn more about the different registration methods, see the Wazuh agent enrollment section. Enable and start the Wazuh agent service.

systemctl daemon-reload
systemctl enable wazuh-agent
systemctl start wazuh-agent

The deployment process is now complete, and the Wazuh agent is successfully running on your Linux system.

Recommended action - Disable Wazuh updates

Compatibility between the Wazuh agent and the Wazuh manager is guaranteed when the Wazuh manager version is later than or equal to that of the Wazuh agent. Therefore, we recommend disabling the Wazuh repository to prevent accidental upgrades. To do so, use the following command:

sed -i "s/^deb/#deb/" /etc/apt/sources.list.d/wazuh.list
apt-get update

Alternatively, you can set the package state to hold. This action stops updates but you can still upgrade it manually using apt-get install.

echo "wazuh-agent hold" | dpkg --set-selections

Uninstall a Wazuh agent

To uninstall the agent, run the following commands:

Remove the Wazuh agent installation.

apt-get remove wazuh-agent

Some files are marked as configuration files. Due to this designation, the package manager does not remove these files from the filesystem. If you want to completely remove all files, run the following command:

apt-get remove --purge wazuh-agent

Disable the Wazuh agent service.

systemctl disable wazuh-agent
systemctl daemon-reload

The Wazuh agent is now completely removed from your Linux endpoint.
