Users may get curious and click on the K2 Application button in SharePoint. Users can be locked out from accessing K2 just in case.
Before You Begin
Make sure you have Admin Access to K2 Management.
Also, make sure the users being restricted are not a part of the Security Administrators role.
Lastly, if you have broken inheritance on Category Security, you may need to provide Deny rights explicitly to the user.
First, try just restricting the users from Designer if they do not need access. This can be done from Management > Designer.
If you choose to remove View rights to Designer, only users in the Security Administrator group can access Designer.
If you would like to just restrict users from a few SharePoint Lists/Libraries, you can focus just on these categories.
