It is normal for security updates to be copied to the -updates pocket of the mirror network in order to provide better update availability and speed to everyone.
We don't expect users to determine if an update is a security update based on the URL where the package can be found.
Instead, our updater will by-default prompt users to install security updates daily (see System Settings | Software & Updates | Updates -> "When there are security updates").

We also publish Ubuntu Security Notices for officially supported packages -- http:// www.ubuntu. com/usn/ and https:/ /lists. ubuntu. com/archives/ ubuntu- security- announce/ -- for users who want to stay on top of security updates manually.
Administrators may also install the unattended-upgrades package if they want to install security updates (or other updates) automatically.
Thanks
