In a Linux environment, there is a possibility to work with three different permissions. The effect of the use of these permissions is different if applied to files or directories. The first permission is read (r). This permission gives a user the possibility to browse the content of a file or directory. Ordinary users have the read permission on a lot of files on a Linux system, because this permission is often granted to others. The second permission is write (w). If applied to files, this permission allows a user to modify the content of an existing file. If it is applied to directories, it allows the user to create and delete files in the designated directory. The last permission is a rather strange one: execute (x). Applied to files, this permission makes a file executable so you can run it as a program. If applied to a directory, it allows a user to browse to subdirectories in this directory. (See Table 4-5.)

public User GetUser(string username, string password) { User user = null; user = new User(); return user; } } } Notice that you just wrote a test, coded a little, and then refactored. This is the coding habit you want to develop. Once you have adopted this style of coding, you will find that you will produce fewer bugs and have a greater sense that the quality of the code you are creating is continually getting better. Now when you rebuild the solution, it builds just fine and your test passes, but nothing of any significance is really happening. To take the next step, you need to modify your UserData class to connect to the Northwind database to get the user s role, along with the username and password, using the username and password passed to the UserData class from the UserTests class. Listing 13-5 shows the UserData.cs file with these changes. Listing 13-5. UserData.cs File Modified to Connect to the Database #region Using directives using System; using System.Collections.Generic; using System.Data; using System.Data.Odbc; using System.Text; using BusinessLayer; #endregion namespace DataLayer { public class UserData { private static string connectionString = "Driver={Microsoft Access Driver (*.mdb)};" + "DBQ=c:\\xpnet\\database\\Northwind.mdb"; public UserData() { } public User GetUser(string username, string password) { User user = null;

If you re used to rights in a Novell environment, then you re familiar with the concept of inheritance. Tip

Listing 5-8. Modified Policy to Take the APEXDEMO User into Account apexdemo@DBTEST> create or replace function vpd_buglist( 2 p_schema in varchar2 default null, 3 p_object in varchar2 default null) 4 return varchar2 as 5 begin 6 if (USER = 'APEXDEMO') and (v('APP_USER') is null) then 7 return ''; 8 else 9 return '( 10 upper(assigned_to) = nvl(v(''APP_USER''), USER) 11 or 12 exists (select 1 from user_repository 13 where upper(username) = nvl(v(''APP_USER''), USER) 14 and admin = ''Y''))'; 15 end if; 16 end; 17 / Listing 5-8 just adds a check to determine if you re connected as the Oracle user APEXDEMO (and you re not running through the APEX application). If so, an empty string is returned to the predicate; that is, you will be able to see all of the records. With just a few simple steps, you have restricted access to the data that a user is able to view and modify. Using VPD where appropriate can drastically simplify your application design and make it easier to maintain and evolve the security logic against all applications accessing a particular set of data.

The effect of inheritance is that a right applied to a high level (for example, on a directory), applies to everything underneath it. In a Linux environment, inheritance is not an issue. The only thing that counts in determining whether a user has permissions or not, is the following question: Is the user an owner of the file If not, is he a member of a group that is owner of the file If not, what are the permissions granted to others
