Install or Upgrade Security Monitoring

Follow the steps in this guide to install or upgrade or upgrade the NGINX Management Suite Security Monitoring module.

Before You Begin

Security Considerations

To ensure that your NGINX Management Suite deployment remains secure, follow the recommendations in this section:

Install NGINX Management Suite and its modules on a dedicated machine (bare metal, container, cloud, or VM).
Make sure that no other services are running on the same machine.
Make sure that the machine is not accessible from the Internet.
Make sure that the machine is behind a firewall.

Installation Prerequisites

Important:
Before you can install this module, you need to have NGINX and ClickHouse installed on your system. Additionally, you will need to add the NGINX Management Suite repository. The Prerequisites topic has detailed instructions on how to fulfill these requirements.

Dependencies with Instance Manager

The Security Monitoring module requires the following versions of Instance Manager to be installed on the management plane:

Security Monitoring	Instance Manager
1.7.0	2.14.0
1.6.0	2.12.0-2.13.0
1.5.0	2.11.0
1.4.0	2.10.0–2.10.1

1.2.0	2.8.0
1.1.0	2.7.0

The Security Monitoring module installation does not automatically install or upgrade Instance Manager. You’ll need to manually install Instance Manager, or upgrade it to a version supported for use with Security Monitoring.

```
sudo yum -y install nms-sm

Restart the NGINX web server:
```
sudo systemctl restart nginx
```
If running Security Monitoring v1.7.0 or higher, start the module:

Accessing the Web Interface
