# Advanced configuration

This topic covers the security context and resource sizing settings for the Harness SMP Operator. The installer applies a default value for each of them, and you override the defaults through the same `override.yaml` file or `clustermgr` flags you use to install.

***

### Configuration topics <a href="#configuration-topics" id="configuration-topics"></a>

Each topic lists the default values the installer applies and shows how to override them with either Helm or clustermgr.

* [Pod security context](/self-managed-enterprise-edition/use-self-managed-enterprise-edition/smp-installationupgrade/operator-installation/advanced-configuration/pod-security-context.md): Change the user and group IDs the containers run as, if the defaults do not meet your organization's security policies.
* [Resource sizing](/self-managed-enterprise-edition/use-self-managed-enterprise-edition/smp-installationupgrade/operator-installation/advanced-configuration/resource-sizing.md): Review the default CPU and memory requests and limits, and resize them if there is a recommendation from the Harness SMP team.
