General Security Concepts

  • Kerberos is an industry standard authentication protocol used to verify user or host identity.
  • Role-based access control (RBAC) is an access control model. In this model, a user can access resources according to his role in the organization.
  • Mandatory Access Control (MAC) is a model that uses a predefined set of access privileges for an object of the system.
  • Authentication is a process of verifying the identity of a person, network host, or system process. The authentication process compares the provided credentials with the credentials stored in the database of an authentication server.
  • Certificate-based authentication is the most secure method of authentication. It provides stronger key for encryption as compared to Digest authentication and sends encrypted passwords across the network. This prevents unauthorized users from intercepting the passwords.
  • Anonymous authentication is generally used for public Internet Web sites. Using this method, a user can establish a connection with a Web server without providing username and password.
  • Authentication is a process of verifying the identity of a person, network host, or system process. The authentication process compares the provided credentials with the credentials stored in the database of an authentication server.
  • Password Authentication Protocol (PAP) transmits user credentials as plaintext.
  • A certificate is a digital representation of information that identifies authorized users on the Internet and intranets.

Retrieving data using the SQL SELECT statement and using single row functions to customize the output

  • /*…*/ and — are used to put comments in an Oracle program.
  • The CREATE TABLE does not end immediately with a semicolon, and a column name cannot start with a numeric value. However, a numeric value can be used in between a column name.
  • Name of a table cannot start with @ special character.
  • Knowing about the GROUP BY clause.

Using sub queries and set operators to solve queries, as well as DDL statements to create and manage tables

  • + (unary), – (unary), *, /, ||, =, !=, <, >, <=, >=, IS NULL, LIKE, BETWEEN, IN, NOT, AND, OR is the correct order of operators precedence.

Creating User Services

  • The identity object that implements the IIdentity interface, is used during the authentication process, when a user’s identity is verified. It contains information about a user who is being validated, such as username and password.
  • The principal object that implements the IPrincipal interface, is used during the authentication process when the application determines the data that can be accessed by a user and the code to be executed. It contains information about a user’s identity, such as username and password, as well as information about a user’s role, such as manager or associate.
  • Setting the MinimizeBox property of a Windows form to false prevents the minimize button from being displayed in the caption bar of the form.

Creating and Managing Microsoft Windows(r) Services, Serviced Components, .NET Remoting Objects, and XML Web Services

  • The SessionID property of the HttpSessionState class identifies an active ASP.NET session by using a unique session ID.
  • The Process.Start method is used to start a Windows application and is registered in the system registry on a computer.
  • The Status property of the ServiceController class specifies the status of the current instance of a Windows service.
  • If a class derives from the ServiceBase class, the OnCustomCommand method is executed when the Service Control Manager (SCM) passes a custom command to the service. This method is used to specify actions when a command with the specified parameter value occurs.
  • The AutoLog property of the ServiceBase class is used to determine whether or not a service automatically logs the entries in the event log when events such as Start, Stop, Pause, and Continue occur.
  • The CreateEventSource method of the EventLog class establishes an application as a valid event source for writing event information to a particular event log on a computer.
  • The Imports statement is used to import namespace names from referenced projects and assemblies.

General high availability technologies in 10g

  • The ORDER BY clause sorts the records in ascending order and it comes last in the SELECT statement.
  • The Online redo log files and the operating system flat file are used to store a copy of a data dictionary.
  • RMAN can be used to take an incremental backup for tablespaces and data files.
  • The rman target/ command is used to maintain backup copies by connecting to the target database and returns the RMAN prompt to issue further backup commands.
  • The NLS_LANG parameter must be set to specify the language, territory, and character set used in an application.
  • CONFIGURE is an RMAN command that configures an RMAN environment.
  • CONFIGURE RETENTION POLICY CLEAR is a command that will configure the retention policy to the default of REDUNDANCY 1.
  • RMAN is used to migrate the database files from conventional file system storage to ASM storage.
  • The control file, target database catalog, and Recovery catalog are used to store the RMAN’s persistent settings.
  • The redo files are opened after executing the ALTER DATABASE OPEN command on a database when it is in MOUNT mode.
  • RMAN can be used to move database objects from a non-ASM disk location to an ASM disk group.

e-business Infrastructure

  • File Transfer Protocol (FTP) is an Internet service that helps in transferring files from one computer to another over the Internet.
  • Layer 2 Tunneling Protocol (L2TP) is a more secure version of Point-to-Point Tunneling Protocol (PPTP). It provides tunneling, address assignment, and authentication.
  • Virtual private network (VPN) uses a tunneling protocol to span public networks, such as the Internet, without security risk. VPN enables remote users to access corporate networks securely by using a tunneling protocol such as PPTP or L2TP.
  • TCP/IP is the primary protocol of the Internet.
  • SMTP uses port 25 by default.
  • Address Resolution Protocol (ARP) is a network maintenance protocol of the TCP/IP protocol suite. It is responsible for the resolution of IP addresses to media access control (MAC) addresses of a network interface card (NIC).
  • FTP uses port 20 and 21 by default.
  • MIME stands for Multipurpose Internet Mail Extensions. It is a standard for multi-part, multimedia electronic mail messages and World Wide Web hypertext documents on the Internet.
