If you are using an Advanced template here are the steps;

1. Create a directory under frontend and rename it rbac
2. Create a file under this new directory, say, AuthorRule.php. Here is a sample file given in the official docs;

namespace app\rbac;


use yii\rbac\Rule;
use app\models\Post;

/**
 * Checks if authorID matches user passed via params
 */
class AuthorRule extends Rule
{
    public $name = 'isAuthor';

    /**
     * @param string|int $user the user ID.
     * @param Item $item the role or permission that this rule is associated with
     * @param array $params parameters passed to ManagerInterface::checkAccess().
     * @return bool a value indicating whether the rule permits the role or permission it is associated with.
     */
    public function execute($user, $item, $params)
    {
        return isset($params['post']) ? $params['post']->createdBy == $user : false;
    }
}

3. Next step is to navigate to http://localhost/path/to/index.php?r=admin/rule and create a new rule with class name \app\rbac\AuthorRule
4. Finally you can add the new rule to roles and permissions depending on your needs.

You can read the official docs for more information on rules; the official docs.
