Uninstall Tenable Security Center

Required Tenable Security Center User Role: Root user

This topic describes how to remove Tenable Security Center from your Linux host.

When you uninstall Tenable Security Center, the software is removed from the system, but some configuration and user data may remain in the installation directory. To completely remove all Tenable Security Center data, you must manually delete the installation directory.

Before you begin:

If you want to migrate your data or keep a record of your configurations, perform a backup before uninstalling Tenable Security Center.

To uninstall Tenable Security Center:

Log in to the host where Tenable Security Center is installed.
Open the command line interface (CLI).
Stop the Tenable Security Center service by running the following command:
Copy
```
# /bin/systemctl stop SecurityCenter
```
Remove the Tenable Security Center package by running the following command:
Copy
```
# dnf remove SecurityCenter
```
(Optional) To remove all remaining user-created and user-modified files, run the following command:
Copy
```
# rm -rf /opt/sc
```
Tenable Security Center is removed.

What to do next:

Ensure no Tenable processes (for example, httpd or tns) are still running by using the ps -fu tns command.
Review your perimeter and host-based firewalls to remove any rules specifically created for Tenable Security Center (for example, port 443 access).
If you used an external PostgreSQL server, uninstalling Tenable Security Center does not remove your data from the external server. You must manage that data separately on the PostgreSQL host.
