Hide bucket items based on role

Imagine I have the following content tree

• sitecore
  • content
    • home
      • KB articles (bucket)
        • article 1 (Template 1)
        • article 2 (Template 1)
        • article 3 (Template 2)

And the following roles -

• Role 1
• Role 2

I have the following scenarios.

1. Role 1 should have read/write access to Article 1 and Article 2, which are based on Template 1.

2. Role 2 should have read/write access to Article 3, which is based on Template 2.

Is there a way of achieving the above scenario in Sitecore?

Thanks

You can try setting the access rights on the Standard Values items of Template 1 and Template 2.

Just set read/write or whatever you need on Standard Values of Template 1 for the Role 1 only. And set read/write or whatever you need on Standard Values of Template 2 for the Role 2 only.

After you do this, all the items which use Template 1 and Template 2 will inherit the access rights from the corresponding Standard Values.
