Hi
The requirement which you mentioned mostly comes OOB itself, here is the doc which you can follow:
For Forum :
Community and forum administrators can give users and groups of users different levels of access to forums and forum content.
There are three components that make up the security settings for forums: forum users, permissions, and forums.
- Forum users
- A forum user is a logical group of users, user groups, or both. This group is used to define memberships to a forum.
- Permissions
- A permission is a combination of:
- access types for a forum
- access types for a given content type
You can create your own permission or use one of the default permissions that the Communities application delivers.

- A forum is the container for user-created content. A forum must be configured with content types and permissions before becoming available for users to contribute content.
To assign permissions to users and user groups, create associations between forum users and permissions for a specific forum.
- You can use forum users and permissions in multiple forums.
- You can add multiple forum users and permissions to one forum.
- You can copy permissions from a parent forum to a child forum or from another forum altogether.
- You can also define user-specific permission exceptions and debug user permissions.
You can create forum users, which you then use to define memberships to a forum.
Create a permission to use to define a user's access to a forum and the content in the forum.
Clone a permission if an existing permission record cannot be modified and you require a permission record with similar settings.
Add a forum user and a permission to a forum to create a forum permission.
