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.

Creating User Services

• The identity object of 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 of the IPrincipal interface is used during the authentication process, when the application determines the data that can be accessed by a user and 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.
• The correct sequence of the classes of the System.Windows.Forms namespace in descending order is as follows:
  1. Control
  2. ScrollableControl
  3. ContainerControl
  4. Forms
• The MinimumSize property of the Form class is used to get or set the minimum size up to which a form can be resized.

• 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.
