-To Disable back button try this:
1.Write this code in master page in page load event

HTML

Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
Response.Cache.SetNoStore();

and
2.Write this code in login page in head section

HTML

<script type="text/javascript">
window.history.forward(-1);
</script>

-To restrict the User by accessing pages using URL try this:
After a user is authenticated, create a session object indicating that. In every page check if that session object has the authenticated value.
Something like:

C#

//In the login page, after user is authenticated
Session["validated"] = true;
 
//In every page that requires authentication, On page load event, check
if(Session["validated"] == null)
    Response.Redirect("Login.aspx");
else
    //do what you want here.
