# Delete a rule from a security group

:::warning

The rule will stop being effective — traffic that was allowed by this rule will be denied. Active sessions on ports that were established according to this rule will be interrupted.

:::

:::warning

Do not delete rules in the [default security group](/cloud-servers/security-groups/about-security-groups.mdx#default-security-group) (the group named `default`), if a Managed Kubernetes cluster is running in the project and pool of this group. Any changes to the group may lead to cluster failures.
