The upcoming Ubuntu 24.10 operating system promises a new feature called “permissions prompting” for an extra layer of privacy and security.
The new permissions prompting feature in Ubuntu will let users control, manage, and understand the behavior of apps running on their machines. It leverages Ubuntu’s AppArmor implementation and enables fine-grained access control over unmodified binaries without having to change the app’s source code.
From Ubuntu Discourse: Ubuntu Desktop’s 24.10 Dev Cycle - Part 5: Introducing Permissions Prompting
This solution consists of two new seeded components in Ubuntu 24.10, prompting-client and desktop-security-center alongside deeper changes to snapd and AppArmor available in the upcoming snapd 2.65. The first is a new prompting client (built in Flutter) that surfaces the prompt requests from the application via snapd. The second is our new Security Center:
In this release the Security Center is the home for managing your prompt rules, over time we will expand its functionality to cover additional security-related settings for your desktop such as encryption management and firewall control.
...
With prompting enabled, an application that has access to the home interface in its AppArmor profile will trigger a request to snapd to ask the user for more granular permissions at the moment of access:
As a result, users now have direct control over the specific directories and file paths an application has access to, as well its duration. The results of prompts are then stored in snapd so they can be queried and managed by the user via the Security Center.
