Oracle 12c PL/SQL Security New Features - Session 6 of 8 - Granting Roles to Procedures
 
06:37
See www.skillbuilders.com/12c-plsql-security for all free modules in this tutorial. It is now in Oracle Database 12c possible to grant roles to the stored program units. Remember this didn't apply to anonymous PL/SQL. Anonymous PL/SQL as always executed with the enabled roles of the invoker. But we can now grant role to a stored procedure. There are a couple of conditions. The role granted must be directly granted to the owner. I'm not sure if this is documented or not or it could've been issues I had during my own testing but certainly the last time I tested this thoroughly I found that if I granted roles to roles to roles to roles as I go down to three, it no longer functions. So that could've been just me or it may be documented. But certainly to be sure, the role granted must be granted directly to the person who's writing the code. Also and it is documented, the owner still needs direct privileges on the object that the code references. That make perfect sense because the role might be disabled at the time that he happens to be creating the object. So you need the role, you need direct privileges on the object referenced by the code. [pause] The invoker however needs absolutely nothing. The invoker now needs nothing, no roles, no privileges. All he needs is execute on the procedure. The invoker will then take on that role during the course of the call. This will tighten up the definer's rights problem and that our user doesn't have much at all. He needs the bare minimum and then only that role will be available, only the role is available to the invoker during the call. Not everything else that the owner happens to have. You can combine this as well with invoker's rights and either way we are controlling privilege inheritance. Invoker's rights plus roles restrict the ability of definer's to inherit privileges from invokers and invokers inherits privileges from definers, both of which raise that ghastly possibility of privilege escalation associated typically to SQL injection. [pause] Grant create session, create procedure to dev, and that will give him select on scott.emp to dev. I've given dev the minimum he needs to write code that hits that table. Then create a role. [pause] Create role r1 and that'll grant select on scott.emp to r1. Finally, grant r1 to dev. It has met the requirements. The role is granted to the owner, the owner does have direct privileges. [pause] So connect as dev/dev and create my favorite procedure. [pause] The same procedure has executed definer's rights and query scott.emp. But now what we can do this new is I can grant r1 to procedure list_emp. [pause] I'll create a very low privileged user now. I need to connect as sysdba and create user low identified by low, and all I shall give him is create session. [pause] And execute on that procedure. [pause] Grant execute on dev.list_emp to low. That's all he's got. He can log on and he can run, run one procedure. What actually is going to happen to him? Let me try to log on. Connect sys low/low set server output on and see if he can run that thing. Just to check, if he tries to select star from scott.emp he is the lowest of the low is my user low. But then execute dev.list_emp, trying to retrieve the CLARKs and it works. And because my user low has virtually no privileges at all, there's no possible danger of the malicious developer being able to inherit dangerous privileges from him. [pause] The final step, that functioned because of the privilege that I mentioned earlier - the privilege that we saw on the previous slide which was inheriting privileges. If I revoke that - and this is what you should be doing in all your systems after upgrade - revoke inherit privileges on user low from public, connect there, and it fails. So the final bit of tightening up the security is to grant the privilege specifically we grant inherit privileges on user low to dev. Now we have a totally secure system and that my low privilege user dev can do that. [pause] And nothing more. My low privileged developer dev can't grab anything in his too as well. That tightens things up totally.

Oracle 12c Grant Role to PL/SQL Procedures - Lesson 1 of 2
 
03:35
A great new security feature that can - among other things - prevent SQL injection and a multitude of other security vulnerabilities. In 12c you can make your PL/SQL code secure using a declarative technique. Simply grant a role to the PL/SQL code and add AUTHID CURRENT_USER so that Oracle runs the code with the privileges of the invoker - not the developer (invoker rights procedures). Presto! Without code reviews and / or debugging you will have hardened your PL/SQL web application! In this free tutorial from SkillBuilders Director of Oracle Database Services, Oracle Certified Master John Watson will demonstrate the development of a simple PL/SQL web application, demonstrate SQL injection and how to prevent it with this new feature.

Simplified DBA-018-User Privileges
 
13:21
A privilege is a right to execute a particular type of SQL statement or to access another user’s object. The Oracle database enables you to control what the users can and cannot do in the database. Privileges are divided into two categories: System privileges: Each system privilege allows a user to perform a particular database operation or class of database operations. For example, the privilege to create tablespaces is a system privilege. System privileges can be granted by the administrator or by someone who has been given explicit permission to administer the privilege. Object privileges: Object privileges allow a user to perform a particular action on a specific object, such as a table, view, sequence, procedure, function, or package. Without specific permission, users can access only their own objects. Object privileges can be granted by the owner of an object, by the administrator, or by someone who has been explicitly given permission to grant privileges on the object. For example, in our demo ERPUSER will own the tables and other users will require read, write object privileges on ERPUSER tables. Example Connect erpuser/welcome1 Grant insert on myable1 to user1; Grant insert on myable1 to user5 Create tablespace erp_data datafile ‘/u01/app/oradata/db11lin/erpdata01.dbf’ size 100M autoextend on; Create user erpuser identified by welcome1 default tablespace erp_data temporary tablespace temp; Grant connect, resource to erpuser; Create user user1 identified by welcome1 default tablespace erp_data temporary tablespace temp; Create table erpuser.mytable1 ( sno number(5), sname varchar2(20)); We can create a table for any user in this format if we have dba privileges. [owner.tablename] Connect user1/welcome1 Insert into erpuser.mytable1 values(100, ‘by user1’); Commit;

Oracle 12c PL/SQL Security New Features - Session 5 of 8 - The New Inherit Privileges Privilege
 
06:47
Learn the Oracle Database 12c Inherit Privileges Privilege. Demonstration and Examples. There's a whole new privilege. The inherit privileges privilege. We indeed inherit any privileges privileged. That's just in privileged of course. Any privileges - system privileges, any privileges is an object privilege or new type objects. We can now assign privileges, grant privileges on users. It limits the owner's inheritance of privileges from the invoker. Oracle Corporation is presumably reasonably happy with the way definer's rights code works and definer's rights code as I demonstrated can be highly dangerous. That hasn't really changed in the current release except is will see with the ability to grant roles to code because in invoker's rights we've got huge differences and that's the inheriting of privileges privilege. If you don't have the inheritance enabled, any attempt to execute invoker's rights code will fail because the definer will not be in able to inherit the rights of the invoker. So I'm going to go straight in to do it and then go through the rest of the slides so we can see the sort of issue. Let me lose 11g and go to 12c. What I shall do is create my low privileged user or drop user dev. I don't think he exists. He doesn't. So I'll create my low privileged user. Grant create session, create procedure, select any table to dev identified by dev. It's the same mechanism I use. The same command I use in 11g. I'm creating a developer with a bare minimum that he needs to do his job, which is writing code that lets people query the database. Then log on as him, comm dev/dev and create my procedure. I'll create a version of the code, create or replace procedure list_emp, author ID current user. Invoker's rights code. Remember, this gives my low privilege user dev the ability to insert something horrible in his code which shall then be executed with the invoker's rights. We create the procedure. Now connect / as sysdba - I'll be the highest possible person there is - set server output on and run the code. Execute dev.list_emp looking for the CLARKS. I can't do it. Even as user sys, I can't run that because of the lack of this new privilege. I can correct the situation. I can grant inherit privileges on user sys - which of course one would never normally do - to dev. So I'm now giving my low privilege user the ability to inherit the privileges of user sys when we are running invoker's rights code. And having done that, the code now succeeds. That's the general principle. Without this inherit any privileges code all that doesn't have any privileges privilege, all your invoker's rights code is now blocked. It simply won't run until you grant that privilege to your trusted user. So without inheritance the invoker's rights code will fail. This privilege is in fact granted by default in 12.1 when a user is created. I believe this is purely for backward compatibility. So you don't have to worry about all your codes ceasing to function the moment you have to upgrade but there's no guarantee that this situation will remain as we go through 12.2, 12.3. Also in upgrade I haven't had the time to test comprehensively every possible method of upgrade but certainly this simple test I've done so far, the privilege does appear to be being granted and we can see it. If we look at who's been granted this privilege so far Select grantee, table_name, privilege from dba_tab_privs where privilege like inherit and we see that straight out of the box inherit privileges on a number of users have been granted to public. They have been granted to public. So if I create a brand new user, I grant connect to jw identified by jw, we will see that in the current release - there he is - inherit has beeen granted to public. In the current release by default, your code will continue to function and Oracle often does this with their [05:46 inaudible] with powerful new features. By default, it's configured so there's no change and in the next release it all changes. That's happened to a quite a few releases, quite a few new features, and it wouldn't surprise me if by the time we get to say 12.2 and certainly by the time we get to 13 this behavior changes. So plan for it and look at that privilege and see who it's been granted to and secure your systems. What you need to do is revoke all the inherit privileges grants that's there by default and then grant inherit any privileges very, very sparingly only to a very few trusted users and that should tighten up the danger of definer's inheriting invoker's rights. So a few trusted schemas, create the code in those schemas only and control this very tightly indeed.

Learn Store Procedure in SQL in Hindi tutorial for beginners
 
08:45
Stored Procedure: Stored Procedure in SQL Server can be defined as the set of logical group of SQL statements which are grouped to perform a specific task. There are many benefits of using a stored procedure. The main benefit of using a stored procedure is that it increases the performance of the database.The other benefits of using the Stored Procedure are given below. Benefits of Using the Stored Procedure One of the main benefits of using the Stored procedure is that it reduces the amount of information sent to the database server. It can become a more important benefit when the bandwidth of the network is less. Since if we send the SQL query (statement) which is executing in a loop to the server through network and the network gets disconnected, then the execution of the SQL statement doesn't return the expected results, if the SQL query is not used between Transaction statement and rollback statement is not used. Compilation step is required only once when the stored procedure is created. Then after it does not require recompilation before executing unless it is modified and reutilizes the same execution plan whereas the SQL statements need to be compiled every time whenever it is sent for execution even if we send the same SQL statement every time. It helps in re usability of the SQL code because it can be used by multiple users and by multiple clients since we need to just call the stored procedure instead of writing the same SQL statement every time. It helps in reducing the development time. Stored procedure is helpful in enhancing the security since we can grant permission to the user for executing the Stored procedure instead of giving permission on the tables used in the Stored procedure. Sometimes, it is useful to use the database for storing the business logic in the form of stored procedure since it makes it secure and if any change is needed in the business logic, then we may only need to make changes in the stored procedure and not in the files contained on the web server.

Oracle SQL PLSQL 12C Tutorial 6 - How to Give Grant to New User
 
01:33
This Video Tutorial Will Describe how to give grants to a new user in oracle 12C version. This command will also work on other versions of database like Oracle 11g Database, Oracle 10g Database, Oracle 9i Database, Oracle 8i Database, Oracle 8 Database and so on. Whenever you create a new user in oracle, you need to give some specific or all grants to that particular user otherwise that user is not able to work at all. Example to create a new table, select data, insert data, for all this type of work your new user only be able to do if and only if proper grants has been given to that user. Otherwise, error message will pop up. Full Syntax will be given in this video tutorial about how to give grants to the newly created user in oracle database. Along with the live example to give grants or authorization to the new user. In this video tutorial, we will give all grants to the new user i.e. DBA grant. All the facilities that a super user can do, we give those to this new user. All the keywords, format, mandatory clauses etc are described in this video.

Oracle 12c PL/SQL Security Features - Lesson 4 of 8 - Roles and PLSQL
 
06:21
Learn how Roles really work with Oracle PL/SQL and why a privilege granted via a role can't be used in PL/SQL. Demonstrations, examples. See all lessons and many more free Oracle Database tutorials at https://www.skillbuilders.com/free-oracle-database-tutorials John Watson: We have the business of roles - roles and PL/SQL. The point here is that roles are invisible to PL/SQL. When you compile your code, only direct privileges are available. When you run your code, only direct privileges are available. This is for definer's rights, I should say. When you run the code, only direct privileges are available to grant to the definer. In effect, the definer's rights code, all roles are disabled within the stored procedure. And certainly roles are disabled when compiling the code. Functionally, it's equivalent to having issued the command SET ROLE NONE. Why is this? Why is it you can't use your privileges? It's perfectly straightforward. It's a technology limitation. Quickly to see what's going on. If I go in and say - let me connect or create a clear schema. I'll create myself, grant dba to jw identified by jw. I've created a user and given him ridiculously high privileges. Connect.... What can you do? You can do pretty much anything. If he wants to delete from scott.emp, he can do it. Let's roll back, because along with his dba role, he has the ability to pretty much anything to use the data. Now we'll create a procedure. If I create a procedure, create delemp as begin, and in there I delete from scott.emp, end, compilation errors. What are they? Show error. At line 2 table of view doesn't exist. That's line 2 delete from scott.emp. I remember way back in version 7, this cause so much confusion before we realized what was going on. It's quite simple that when we are within the code, as the definer or the invoker, because this is definer's rights code, when we are within the definer's rights code block or indeed when we are compiling a definer's rights code block, the roles are disabled and that's why we cannot see it. But why is this and why do I say it's a technology limitation? It's because roles can be enabled and disabled. They can be enabled or disabled. That makes it logically impossible to consider a role when executing a stored procedure because I might have the role enabled while I compile it, but how do I know that it's going to be enabled when I run it? If I grant execute on the code to a third party, he doesn't have the role at all and that he must not even be logged on. So it becomes a logical impossibility because of the way roles are used because roles are enabled or disabled. You can dynamically switch them on and off. It's a logical impossibility to use role within definer's rights program module. Invoker's rights code, however, is very different. That infuses some interesting issues. Invoker's rights code can use any roles that happen to be enabled for the user at the time that he invokes it in exactly the same way that an anonymous PL/SQL can use any enabled roles. In the security point of view, the definer can in effect grab any roles within his code that the invoker happens to have. Dave: [Question], John, pardon. How do you enable or disable a role? John: Right now there's several techniques. I won't spend too much time demonstrating. The easiest technique will be alter - I can set role none. And that will have disabled all my roles. Now if you look at this, I've got nothing. If I try to run my code and query - let's see. Yes. If I try to delete from scott.emp I can't see it. So I'll set role dba and now of course I can. That's the easiest way. In fact, there are much more [05:07 inaudible] ways to switch roles on and off. We can do it with operating system authentication and I can do it with proxy authentication. We have a persistent session through application server as well as a user when we pass that session out to many of the users that can switch roles on and off. That's the persistent session switch identities. Perhaps, best of all, I can create what I call secure application roles well it protect the role with a package and that can contest any number of issues - environment variables, maybe the time, maybe your IP address, perhaps the program you're using and switch roles on and off accordingly. So there are many ways for controlling roles and you should do it. Blindly granting roles and letting them be enabled all the time is not good security. The end result for this, however, you can get some pretty unexpected results within your code. I've tried to run through in our first half hour some of the issues that we see with PL/SQL in release 11g and earlier. After a short break, we'll move on to the 12c features.
