Rails URL直打ちで詳細画面へ行かない様にしたい

Railsで簡単な掲示板アプリを作成しています。
localhost:3000/projects/2/tasks/1のようにURLを入力すると、projectに紐づいていないTaskの詳細情報が確認できてしまうことが分かりました。
URL直打ちで詳細画面へ行かない様にしたいのですが、どの様にすれば良いか分からず詰まっております。

class TasksController < ApplicationController
 before_action :set_project
 before_action :set_task, only: %i[show edit update destroy]
 def index
   @tasks = @project.tasks
 end
 def show; end
 def new
   @task = Task.new
 end
 def edit; end
 def create
   @task = Task.new(task_params)
   if @task.save
     redirect_to [@project, @task], notice: 'Task was successfully created.'
   else
     render :new
   end
 end
 def update
   if @task.update(task_params)
     redirect_to [@project, @task], notice: 'Task was successfully updated.'
   else
     render :edit
   end
 end
 def destroy
   @task.destroy
   redirect_to project_tasks_url, notice: 'Task was successfully destroyed.'
 end
 private
 def set_project
   @project = Project.find(params[:project_id])
 end
 def set_task
   binding.pry
   @task = Task.find(params[:id])
 end
 def task_params
   params.require(:task).permit(:title, :status, :deadline, :completion_date, :description).merge(project_id: params[:project_id])
 end
end

show
1<p id="notice"><%= notice %></p>
2<p>
3 <strong>Title:</strong>
4 <%= @task.title %>
5</p>
6<p>
7 <strong>Status:</strong>
8 <%= @task.status %>
9</p>
10<p>
11 <strong>Deadline:</strong>
12 <%= @task.deadline.strftime('%Y-%m-%d %H:%M') if @task.deadline? %>
13</p>
14<p>
15 <strong>Completion date:</strong>
16 <%= @task.completion_date %>
17</p>
18<p>
19 <strong>Description:</strong>
20 <%= @task.description %>
21</p>
22<%= link_to 'Edit', edit_project_task_path(@task.project_id, @task) %> |
23<%= link_to 'Back', project_tasks_path %>
