## Installation
|

|
||||
### Requirements
|
||||
|
||||
Refer <https://documentation.wazuh.com/current/quickstart.html#requirements>.
|
||||
|
||||
[Open ports](https://documentation.wazuh.com/current/getting-started/architecture.html#required-ports).
|
||||
|
||||
### Procedure
|
||||
|
||||
Refer the [installation guide](https://documentation.wazuh.com/current/installation-guide/index.html) and
|
||||
[installation alternatives](https://documentation.wazuh.com/current/deployment-options/index.html) pages.
|
||||
|
||||
<details style="margin-bottom: 1em">
|
||||
<summary>Docker compose</summary>
|
||||
|
||||
1. Clone the repository containing the compose files.<br/>
|
||||
Make sure to specify the branch:
|
||||
|
||||
```sh
|
||||
git clone 'https://github.com/wazuh/wazuh-docker.git' -b 'v4.7.4'
|
||||
```
|
||||
|
||||
1. Enter the directory corresponding to the setup one wants:
|
||||
|
||||
```sh
|
||||
cd 'wazuh-docker/single-node'
|
||||
cd 'wazuh-docker/multi-node'
|
||||
```
|
||||
|
||||
1. \[On Linux hosts]
|
||||
|
||||
```sh
|
||||
sudo sysctl -w vm.max_map_count=262144
|
||||
```
|
||||
|
||||
1. Generate the self-signed certificates:
|
||||
|
||||
```sh
|
||||
docker-compose -f 'generate-indexer-certs.yml' run --rm 'generator'
|
||||
```
|
||||
|
||||
Or put one's own in the `config/wazuh_indexer_ssl_certs` directory:
|
||||
|
||||
```sh
|
||||
$ ls 'config/wazuh_indexer_ssl_certs'
|
||||
admin-key.pem root-ca-manager.pem wazuh.dashboard-key.pem wazuh.indexer.pem
|
||||
admin.pem root-ca.key wazuh.dashboard.pem wazuh.manager-key.pem
|
||||
root-ca-manager.key root-ca.pem wazuh.indexer-key.pem wazuh.manager.pem
|
||||
```
|
||||
|
||||
1. Run the composition:
|
||||
|
||||
```sh
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
> Expect several `Failed to connect to Wazuh indexer port 9200` log messages and the _Wazuh dashboard server is not
|
||||
> ready yet_ message in the web UI until the Wazuh indexer finishes starting up.<br/>
|
||||
> It takes about 1 minute for the indexer to start up, then the dashboard setup process continues normally.<br/>
|
||||
> This is due to the dashboard container using `curl` to ping the indexer's API to know when it is up.
|
||||
|
||||
</details>
|
||||
|
||||
Once the service started, open <https://localhost>.<br/>
|
||||
The default credentials are `admin`:`SecretPassword`.
|
||||
|
||||
## Configuration
|
||||
|
||||
### Local configuration
|
||||
|
||||
Refer <https://documentation.wazuh.com/current/user-manual/reference/ossec-conf/index.html>.
|
||||
|
||||
The `ossec.conf` file is the main configuration file for the manager, and is used by the agents for defaults.<br/>
|
||||
Errors in this file **will** prevent the manager from starting.
|
||||
|
||||
The file is in XML format. The outermost XML tag is `<ossec_config>`.<br/>
|
||||
There can be more than one `<ossec_config>` tag. Repeating sections may override previously defined ones.
|
||||
|
||||
```xml
|
||||
<ossec_config>
|
||||
<alerts>…</alerts>
|
||||
<wodle name="aws-s3">…</wodle>
|
||||
</ossec_config>
|
||||
```
|
||||
|
||||
### Shared configuration
|
||||
|
||||
Refer <https://documentation.wazuh.com/current/user-manual/reference/centralized-configuration.html>.
|
||||
|
||||
The `agent.conf` file is very similar to `ossec.conf` but is used to distribute configuration information to agents.
|
||||
|
||||
```xml
|
||||
<agent_config>
|
||||
…
|
||||
</agent_config>
|
||||
```
|
||||
|
||||
When `agent.conf` is used, it is merged onto `ossec.conf`. Its settings will override or be added to the ones in the
|
||||
local configuration.
|
||||
|
||||
Several configurations may be created based on the `name`, `OS` or `profile` of agents:
|
||||
|
||||
```xml
|
||||
<agent_config name="agent_name">
|
||||
<localfile>
|
||||
<location>/var/log/my.log</location>
|
||||
<log_format>syslog</log_format>
|
||||
</localfile>
|
||||
</agent_config>
|
||||
|
||||
<agent_config os="Linux">
|
||||
<localfile>
|
||||
<location>/var/log/linux.log</location>
|
||||
<log_format>syslog</log_format>
|
||||
</localfile>
|
||||
</agent_config>
|
||||
|
||||
<agent_config profile="database">
|
||||
<localfile>
|
||||
<location>/var/log/database.log</location>
|
||||
<log_format>syslog</log_format>
|
||||
</localfile>
|
||||
</agent_config>
|
||||
```
|
||||
|
||||
## AWS integration
|
||||
|
||||
Refer <https://documentation.wazuh.com/current/cloud-security/amazon/index.html> and
|
||||
<https://documentation.wazuh.com/current/user-manual/reference/ossec-conf/wodle-s3.html>.
|
||||
|
||||
### Instances
|
||||
|
||||
Install the agent on hosts that need to be monitored.
|
||||
|
||||
### Services
|
||||
|
||||
Service monitoring requires one S3 bucket to save the data flow generated by Wazuh, and then redirect this to the rest
|
||||
of the services from AWS.
|
||||
|
||||
The AWS module requires credentials to be able to pull log data from services.<br/>
|
||||
`wazuh-modulesd` is executed by the `root` user, so the credentials file must be placed at `/root/.aws/credentials` if
|
||||
used. Environment variables work as effectively.
|
||||
|
||||
Setup the module in the manager's configuration file.<br/>
|
||||
Requires one `bucket` attribute.<br/>
|
||||
Can be added in a separate `<ossec_config>` section.
|
||||
|
||||
```xml
|
||||
…
|
||||
<ossec_config>
|
||||
<wodle name="aws-s3">
|
||||
<bucket type="cloudtrail">
|
||||
<name>wazuh-bucket</name>
|
||||
<path>cloudtrail<path>
|
||||
</bucket>
|
||||
<bucket type="wpcflow">
|
||||
<name>wazuh-bucket-vpc</name>
|
||||
</bucket>
|
||||
</wodle>
|
||||
</ossec_config>
|
||||
```
