# Application Layer The Application Layer is the highest level in our multi-layered architecture. This layer acts as the primary interface for the interaction with the system. Each application stored at the Application Layer is associated with a security policy that governs its execution. These policies define the conditions under which applications can be accessed and executed. For example, some applications may be publicly available to all users, while others may restrict access to a predefined group of authorized users. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
