Security Management

 

1.  What is Windows Authentication?

      Authentication is a process of validating a user’s identification. To enforce security, all users must be authenticated through a logon process. Windows authentication can be classified into two types:

·        Interactive logon

·        Network logon

2.  What is the Kerberos?

      Kerberos is the default authentication protocol in Windows 2000. It is used for only domain logon authentication request, and Windows 2000 does not use it for local logon authentication request.

3.  What are digital certificates?

Digital certificates consist of data used to validate the identity of a user, computer, or service.

4.  How the security areas can be configured?

      Windows 2000 defines the security that can be configured through local and non-local policies, using Active Directory Users and Computers.

5.  What is a security template?

      A security template is a predefined security configuration. You fine-tune the settings of security template to suit you requirements, and then apply the settings to a GPO.

6.  What an Audit policy defines?

      An Audit policy defines the events that are tracked in the audit process. When you set up auditing for a folder, the files and subfolders created within the folder inherit auditing.

7.  What is the Event Viewer?

       The Event Viewer snap-in allows you to monitor and log events that occur on the computer. Event Viewer records events in three logs:

·        Application

·        System

·        Security

 

Backup and Fault Tolerance

 

1.  What is a backup?

   Data backup is the most established and reliable principle of guarding against data loss. The Windows 2000 Backup utility allows you to back up data restore data and create emergency disk.  

2.  What kind of backup is supported by Windows 2000?

      Windows 2000 supports three types of backup:

·      Full             - this backup method backs up all files on your computer, including the Windows 2000 system files. Full Backup resets the archive bit of all the files that it backs up.

·      Incremental – this backup method backs up the files that are new or have been changed since the last backup. This is a fast and efficient backup method because it searches for only new or changed files and back them up. Incremental Backup resets the archive bit of the backed up file.

·      Differential  - this backup method backs up only those files that have been changed since the last full backup. The archive bit is not reset in this backup. Restoring from differential backup is very fast, as you require only two sets of tapes to restore the entire data. One tape is the last full backup and other is the last differential backup.

3.  How the popular backup devices are classified?

     The devices used to back up data are classified according to the media that they use. Popular backup devices include:

·        Digital Audio Tape (DAT)

·        Digital Linear Tape

·        Magneto Optical disks

·        CD-Rs

4.  What is the Fault Tolerance?

     Fault Tolerance is the ability of an operating system to run in spite of error conditions.

5.  How Windows 2000 implements the Fault Tolerance?

     Windows 2000 implements fault tolerance by using RAID and Mirroring. To create RAID and mirrored volumes, dynamic disks are required.
