How to log in to an Oracle Database - Answer Video - Database Tutorials 42 This video explains about how to log in to an Oracle database. This also explains about how to create an user and grant a role to that user. In this case, the role granted is 'dba'. The following things happen in this Oracle Database Tutorial. * We invoke SQLPLUS using the CMD utility which came with Windows 7 (Just click START in your Windows 7 and type CMD in the field which is immediately above the START button. 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.

How and When to Write SQL in PLSQL
 
01:01:17
Oracle PL/SQL makes writing SQL so darned easy -- in fact, it is way too easy to write SQL. As a result, PL/SQL developers take SQL totally for granted, and very few organizations have any sort of guidelines in place for when, where and how to write SQL. The result? The same or similar SQL statements repeated throughout the application, making it very hard to optimize and maintain the code. This webinar starts by reviewing the role of SQL in PL/SQL applications, and the key challenges involved when writing SQL. We then step through the most important best practices for SQL construction, ranging from avoiding SQL repetition to full qualification of variable and column names. After viewing this webinar, you will be well positioned to establish and follow a set of guidelines for SQL construction that will have a significant impact on application performance and maintainability. https://asktom.oracle.com http://www.plsqlchallenge.com http://www.oracle-developer.net/ http://oracle-base.com/ http://www.oracle.com/webfolder/technetwork/tutorials/plsql/sfdemo.zip http://goo.gl/FPG79Z http://stevenfeuersteinonplsql.blogspot.de/ https://twitter.com/sfonplsql

Career Advice : How to Become a  Database Administrator or DBA: Career Guidance animation videos
 
06:47
Career Advice : How to Become a Database Administrator or DBA: Career Guidance animation videos What is a database? Companies storing vast quantities of data use databases which are looked after by DBA's. This short, animated video will give you a high level overview of this role. This video is suitable for career seekers and anyone else wanting an overview/description of this role. We at funza have interviewed professionals regarded as experts in their domain and come up with this video. It focuses on providing answers to these questions: a. Overview of the role b. Requirements of the role c. Joys of the role d. Challenges of the role e. An average day f. Future prospects References: http://www.geteducated.com/career-center/detail/computer-scientist-and-database-administrator http://money.usnews.com/careers/best-jobs/database-administrator Overview: Let us understand the term Database administrator by observing an activity most of us indulge in. Let me explain the concept by mapping it to a common activity -The activity is withdrawing money from a bank. While you are withdrawing money, there are quite a few things happening in the background. Thousands of other customers may be doing the same thing, and this, is not affecting your session.and this is not affecting you in any way. ACCESS to your data is IMPORTANT where banking is concerned. You could ask your bank for past account transactions, and the bank has has an obligation to provide it. Since banking is a frequent activity, performance is taken for granted. When you are at an ATM, for example, you expect your transaction to be completed in a short period of timequickly. Now let us look at things from a banks perspective. What we are seeing here is a vast quantity of data that the bank has to store and provide its customers.. This data is stored on one or more DATABASES. But it is as we saw, it's much more than just DATA.. There is the concept of concurrency where data can be accessed by multiple customers. The concept of data security, where your data is protected The concept of performance where data is accessible in acceptable time frames. data can only be seen by you. Performance and high availability, where data is always available. Data and the this extra functionality around data are is made possible by a DBMS or data base management system. And the people responsible for managing a DBMS are DBA's or database administrators. What does a DBA Do? Now any company that needs to store vast quantities of data will use one or more databases. Thus, databases are present in a wide spectrum of companies. And not surprisingly these companies recruit DBA's to look after this data. DBAs are involved in a variety of activities: a. They install and maintain databases. b. They upgrade databases to newer versions when available c. They take backups of databases so data can be recovered if a system crashes d. They also export data across databases Monitoring databases is another component of a DBAs average day. They run tests to measure the health of a database. For example databases can fill up which means that no more information can be added. When this happens work can grind to a halt. Similarly performance can become an issue resulting in Calls to Customer Service Agents which companies never want. So this means that a DBA has to also be a problem solver DBAs also plan and implement security measures to safeguard databases. As a customer you would not want your banking or medical records to fall into wrong hands. Lastly DBAs spend a substantial amount of time in meetings with company management and vendors.

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.

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.

How to Grant Roles and Privileges in  Sql Anywhere | Sybase Central
 
01:27
In this video you will learn how to assign or grant roles and privileges in sql anywhere database. The users can be given various roles and privileges to perform different tasks A role-based access control model is provided for the execution of privileged operations. A role-based security model provides complete control and granularity for the privileges you want to grant to users. Each privileged operation a user can perform in the database requires one or more system or object-level privileges. A system privilege is a right to perform an authorized database task. For example, the CREATE TABLE system privilege allows a user to create self-owned tables. An object-level privilege is a right to perform an authorized task on a specified object. For example, having ALTER privileges on TableA allows a user to alter that table, but not other tables. A role is a collection of one or more system privileges, object-level privileges, or roles. You can grant roles to other roles to create a role hierarchy. Granting a role to a user is equivalent to granting the user the underlying system privileges for the role. Each new or migrated database includes a predefined set of roles you can use to get started. These system roles act as a starting point for implementing role-based security. There are three types of roles in the role-based security model: system roles, user-defined roles (which include user-extended roles), and compatibility roles. View the roles and privileges a user has in SQL Central by clicking the user and viewing the details that are displayed. You can also retrieve the details using the sp_displayroles system procedure. A privilege is a right to perform a privileged operation on the system. For example, altering a table is a privileged operation, depending on the type of alteration you are making. There are two types of privileges: system privileges and object-level privileges. System privileges give you the general right to perform a privileged operation, while object-level privileges restrict you to performing the operation on a specific object. For example, if you have the ALTER ANY TABLE system privilege, you can alter any table in the system. If you do not, you can only edit tables you create or tables on which you have the ALTER TABLE object-level privilege. System privileges are built in to the database and can be granted or revoked, but not created or dropped. With the exception of the MANAGE ROLES and UPGRADE ROLE privileges, system privileges cannot have system privileges granted to, or revoked from, them. Each system privilege, with the exception of the SET USER system privilege, is granted by default to either the SYS_AUTH_SA_ROLE or SYS_AUTH_SSO_ROLE compatibility role, but not both. The SET USER system privilege is granted to both roles (WITH ADMIN OPTION to SYS_AUTH_SSO_ROLE and WITH NO ADMIN OPTION to SYS_AUTH_SA_ROLE). You grant and revoke system and object-level privileges by using the GRANT and REVOKE statements.

How to Grant Roles and Privileges in  Sql Anywhere | Sybase Central
 
01:12
In this video you will learn how to assign or grant roles and privileges in sql anywhere database. The users can be given various roles and privileges to perform different tasks A role-based access control model is provided for the execution of privileged operations. A role-based security model provides complete control and granularity for the privileges you want to grant to users. Each privileged operation a user can perform in the database requires one or more system or object-level privileges. A system privilege is a right to perform an authorized database task. For example, the CREATE TABLE system privilege allows a user to create self-owned tables. An object-level privilege is a right to perform an authorized task on a specified object. For example, having ALTER privileges on TableA allows a user to alter that table, but not other tables. A role is a collection of one or more system privileges, object-level privileges, or roles. You can grant roles to other roles to create a role hierarchy. Granting a role to a user is equivalent to granting the user the underlying system privileges for the role. Each new or migrated database includes a predefined set of roles you can use to get started. These system roles act as a starting point for implementing role-based security. There are three types of roles in the role-based security model: system roles, user-defined roles (which include user-extended roles), and compatibility roles. View the roles and privileges a user has in SQL Central by clicking the user and viewing the details that are displayed. You can also retrieve the details using the sp_displayroles system procedure. A privilege is a right to perform a privileged operation on the system. For example, altering a table is a privileged operation, depending on the type of alteration you are making. There are two types of privileges: system privileges and object-level privileges. System privileges give you the general right to perform a privileged operation, while object-level privileges restrict you to performing the operation on a specific object. For example, if you have the ALTER ANY TABLE system privilege, you can alter any table in the system. If you do not, you can only edit tables you create or tables on which you have the ALTER TABLE object-level privilege. System privileges are built in to the database and can be granted or revoked, but not created or dropped. With the exception of the MANAGE ROLES and UPGRADE ROLE privileges, system privileges cannot have system privileges granted to, or revoked from, them. Each system privilege, with the exception of the SET USER system privilege, is granted by default to either the SYS_AUTH_SA_ROLE or SYS_AUTH_SSO_ROLE compatibility role, but not both. The SET USER system privilege is granted to both roles (WITH ADMIN OPTION to SYS_AUTH_SSO_ROLE and WITH NO ADMIN OPTION to SYS_AUTH_SA_ROLE). You grant and revoke system and object-level privileges by using the GRANT and REVOKE statements.

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.

For example, you must explicitly be granted permission to use the select command on the authors table. Object access permissions are granted and revoked by the object owner, who can grant them to other users. Group Administrator can grant and revoke certain set of permissions to group.

how to create directory in oracle 12c, 11g
 
02:52
Use the CREATE DIRECTORY statement to create a directory object. A directory object specifies an alias for a directory on the server file system where external binary file LOBs and external table data are located. You can use directory names when referring to BFILEs in your PL/SQL code and OCI calls, rather than hard coding the operating system path name, for management flexibility. All directories are created in a single namespace and are not owned by an individual schema. You can secure access to the BFILEs stored within the directory structure by granting object privileges on the directories to specific users. You must have CREATE ANY DIRECTORY system privilege to create directories. When you create a directory, you are automatically granted the READ and WRITE object privileges on the directory, and you can grant these privileges to other users and roles. The DBA can also grant these privileges to other users and roles. WRITE privileges on a directory are useful in connection with external tables. They let the grantee determine whether the external table agent can write a log file or a bad file to the directory. For file storage, you must also create a corresponding operating system directory, an ASM disk group, or a directory within an ASM disk group. Your system or database administrator must ensure that the operating system directory has the correct read and write permissions for Oracle Database processes. Privileges granted for the directory are created independently of the permissions defined for the operating system directory, and the two may or may not correspond exactly. For example, an error occurs if sample user hr is granted READ privilege on the directory object but the corresponding operating system directory does not have READ permission defined for Oracle Database processes. ---------------------------------------------------------------------------- Default directory is DATA_PUMP_DIR.Below command is to get directory name and directory path. SELECT directory_name, directory_path FROM dba_directories WHERE directory_name='DATA_PUMP_DIR' DIRECTORY_NAME DIRECTORY_PATH --------------- ------------------------------------------------------- DATA_PUMP_DIR /u01/app/mohammad75/product/12.1.0/dbhome_1/rdbms/log/

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;

SAP ASE 16 Learning Part 11 Administering System Roles and Logins. To Learn or Teach Linux visit www.theskillpedia.com, A Marketplace for Learners and Trainers. Session 11 Administering System Roles and Logins Ram N Sangwan Managing login accounts The responsibility of adding new login accounts to Adaptive Server, adding users to databases, and granting users permission to use commands and access database objects is divided among the system security officer, system administrator, and database owner Managing users in Adaptive Server Creating login accounts The following steps describe creating a login account for a particular server and manage permissions for the users. A system security officer creates a login account for a new user. A system administrator or database owner adds a user to database or assigns a user to a group. A system security officer grants specific roles to the user. A system administrator, database owner, or object owner grants the user, or group specific permissions on specific commands and database objects. Creating login accounts To sets up an account for the user “maryd” with the password “100cents,” the default database , the default language , and no full name: create login maryd with password "100cents" Creating login accounts The password requires quotation marks. Changing login accounts Use alter login to add, drop or change attributes of a login and their corresponding values. It allows you to: Add or drop auto activated roles Change a password Change the login profile association Change or add a full name Specify the password expiration and the minimum password length Specify the maximum failed attempts Specify an authentication mechanism Specify the default language and default database Invoke a login script Exempt inactive login accounts Changing login accounts Changing login accounts This example changes the default database for the login account anna to pubs2: alter login anna modify default database pubs2 This example changes the default language for claire to French: alter login claire modify default language french Dropping login accounts drop login mikeb, rchin System-defined roles System administrator privileges System administrators: Handle tasks that are not application-specific Displaying information about roles Finding role IDs and names To find a role ID when you know the role name, use: Any user can execute role_name. Viewing active system roles Use show_role to display the currently active system roles for the specified login: Granting and revoking roles Granting roles To grant roles to users or other roles, use: All roles listed in the grant statement are granted to all grantees. If you grant one role to another, it creates a role hierarchy. For example, to grant Susan, Mary, and John the “financial_analyst” and the “payroll_specialist” roles, enter: grant role financial_analyst, payroll_specialist  to susan, mary, john Understanding grant and roles Use the grant command to grant permission on objects to all users who have been granted a specified role, whether system or user-defined. This allows you to restrict use of an object to users who have been granted any of these roles: Any system-defined role Any user-defined role

If user management is enabled in your Kushal Project, then User management menu gets created in output, which will have the complete functionality required to maintain users and their permission. Admin user will be created by default, and once admin logs in, he will be able to create users and their permission restrictions. To Create New Users - Click User Management Click Manage Users By Default, a role called Administrator is created in the designed application with the following details - To create a New User, Click New. Enter the details of the user. If you create users and if those users are to be stopped for further usage, then in ‘User Management’ users can be made ‘Not Active’. If User is having the same role as Administrator, then click on the Is Administrator option. Users without administrator permission will not have access to User Management. Click Save. You can see the added User in the Grid. To Assign the roles To Users The application will have as many modules as you have defined in Kushal application. An Admin can assign the roles to each user, restricting access to specific modules based on the application requirement. Click on Manage User Roles Select the User Name in Login Name Window. Then Click the checkboxes to assign the Permissions for the modules. Click Save to save permissions of the User. You will get a confirmation message. Note that When User Management Is enabled, the application will ask User Name and Password while logging into the application. Depending on the permission a user will be able to open only the Forms to which the Admin has granted access. Thank you for watching this tutorial. In the next video(https://www.youtube.com/watch?v=azetvhaNwCM&list=PLfjcN98NVeQFmaP1_AIYvahfxWK-YKbtL&index=37), we will learn about Version Management of Kushal Projects.
Basics of Oracle Internal Structure - Database Tutorial 43
 
10:27
Video 43 Basics of Oracle Internal Structure This video explains the basics of Oracle Internal Structure. Inside the Oracle database, everything gets stored in Tablespaces. A tablespace is a logical structure that is made up of one or multiple data files. The operating can only see the data files. For it, these files are just like other files. But, once these files are properly opened up by Oracle, then they present a logical structure called Tablespace within Oracle. It is important to remember, tablespaces are logical structure that can be seen only from inside of Oracle. Outside of it, that is, from the Operating System's perspective, they would be nothing but a bunch of data files. For an user to log in to the database he/she must have an user account within that database. These users are called just 'users'. However, users can be granted privileges to create tables or indexes or other objects. And if an user creates a table, that is owned by that user, then that user can also be called as a schema.

What is INFERENCE ATTACK? What does INFERENCE ATTACK mean? INFERENCE ATTACK meaning & explanation

What is INFERENCE ATTACK? What does INFERENCE ATTACK mean? INFERENCE ATTACK meaning - INFERENCE ATTACK definition - INFERENCE ATTACK explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ An Inference Attack is a data mining technique performed by analyzing data in order to illegitimately gain knowledge about a subject or database. A subject's sensitive information can be considered as leaked if an adversary can infer its real value with a high confidence. This is an example of breached information security. An Inference attack occurs when a user is able to infer from trivial information more robust information about a database without directly accessing it. The object of Inference attacks is to piece together information at one security level to determine a fact that should be protected at a higher security level. Computer security inference control is the attempt to prevent users to infer classified information from rightfully accessible chunks of information with lower classification. Computer security professionals install protocols into databases to prevent inference attacks by software. Techniques to detect and remove inference channels can be organized into two categories. The ?rst category includes techniques that detect inference channels during database design time. Inference channels are removed by modifying the database design or by increasing the classi?cation levels of some of the data items. Techniques in the second category seek to eliminate inference channel violations during query processing time. If an inference channel is detected, the query is either refused or modi?ed to avoid security violations. While design-time is easier to manage and implement, query-time approach allows more availability of data than in design-time approach because more information (past and present queries/answers) can be used for disclosure inference. Disclosure Monitor (DiMon) detects and eliminates inference channels based on database constraints. A Disclosure Inference Engine (DiIE) is proposed, that generates all information that can be disclosed based on a user’s previous query results, the current query results, and a set of Horn-clause constraints. Dynamic Disclosure Monitor (D2Mon) guarantees data confidentiality and maximal availability even in the presence of inferences and updates. It is our intention to complement an existing access control mechanism (e.g., DAC, MAC, RBAC) to address the inference problem. MAC: In the Mandatory Access Control (MAC) model, users are given permissions to resources by an administrator. Only an administrator can grant permissions or right to objects and resources. Access to resources is based on an object's security level, while users are granted security clearance. Only administrators can modify an object's security label or a user's security clearance. DAC: In the Discretionary Access Control (DAC) model, access to resources is based on user's identity. A user is granted permissions to a resource by being placed on an access control list (ACL) associated with resource. An entry on a resource's ACL is known as an Access Control Entry (ACE). When a user (or group) is the owner of an object in the DAC model, the user can grant permission to other users and groups. The DAC model is based on resource ownership. RBAC: In the Role-Based Access Control (RBAC) model, access to resources is based on the role assigned to a user. In this model, an administrator assigns a user to a role that has certain predetermined right and privileges. Because of the user's association with the role, the user can access certain resources and perform specific tasks. RBAC is also known as Non-Discretionary Access Control. The roles assigned to users are centrally administered. Dynamic Disclosure Monitor Architecture uses this MAC to detect any direct security violation, if any direct security violation is detected the query is rejected then and there, otherwise it is passed through inference engine to disclose data that can be inferred. All the disclosed data obtained from inference engine is again sent to MAC to detect any direct security violation. If any violation is detected the query is rejected, otherwise answered.

The game is set in Ancient Greece, and will feature RPG elements, including dialogue options and the ability to select between a male or female protagonist. The player takes control of a Spartan rejected by their family, making the journey from outcast mercenary to legendary hero, learning the truth about their past along the way. Both Alexios and Kassandra start the game as a mercenary and a descendant of the Spartan king Leonidas I. They inherit his broken spear, which is forged into a blade to become a weapon that grants the player special abilities in combat. The game uses a skill tree system that allows the player to unlock new abilities. The three skill trees include "hunter", which improves player character's archery, "warrior" which puts emphasis on combat, and "assassin" which focuses on stealth. This replaces the system used in Origins, which granted the player a series of passive abilities.
