How can I control which users can access the Project Wall?

On the Administration page you will find configuration tools for Jitter.

Select Post Permissions which will take you to the window below.

Selected Project Roles  have permission to see and post on project walls.  To add a custom permission add a new Project Role in JIRA and add users to that group in selected projects and give that group permission here, in the Post Permission settings.
