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.

A CMD window will open) * We also invoke SQLPLUS using the program group in which Oracle has been installed. * We also invoke Database Control * We then create a user. * And we assign a password to that user. * Using those (username and password) we are able to connect to the Oracle Database.

Grants With Admin Option - Create roles in Oracle 12c Part - 2
 
13:03
It becomes difficult for DBA to handle granting privileges when there are tons of requests. With admin option is a wonderful feature which reduces stress of db admin and user gets authority to grant specific privileges to other user, this is the pros side and cons is un ethical use of the privileges by certain users. It is necessary for DB admin to monitor activities of users whom this privileges are provided.

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.

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.

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it
