Learning Objectives Configure disk quotas Repairing and
Defragmenting Set permissions to files and folders Configuring
system audit Schedule shadow copy
Slide 3
Configure disk quotas disk quotas allow administrators to
control disk space usage on each disk volume This functionality can
be deployed in different ways: 1- Monitoring only; 2- Monitoring
and warning without taking measures; 3- Limiting the usage of disk
4 -Quotas are applied to all users of the volume unless exceptions
are configured for individual users Disk Quotas configuration
Slide 4
Repairing and Defragmenting Fragmentation causes a disk
subsystem to perform more data-seeking operations, slowing the rate
at which data is transferred and resulting in sluggish disk
performance. Reasons of fragmentation a disk Performing disk
fragmentation
Slide 5
Files and Folders Permissions NTFS file permissions determine
which users can view or update files Files are grouped into three
types: user files, system files and program files To allow
collaboration in file servers, it requires you to grant permissions
to groups of users NTFS presents two levels of permissions: basic
permissions and special permissions

Slide 9
Encrypting File System When an attacker who has physical access
to a computer can start the computer from a different operating
system (or simply reinstall Windows) or remove the hard disk and
connet it to a different computer. Any of these very simple
techniques would completely bypass NTFS security, granting the
attacker full access to files and folders. EFS protects files and
folder by encrypting them on the disk. If an attacker bypasses the
operating system to open a file, the file appears to be random,
meaningless bytes. Windows controls access to the decryption key
and provides it only to athorized users.

Files and Folders Ownership What does ownership mean Who can
take the ownership of a file or directory How to take the
ownership
Slide 11
Auditing Object of auditing Performing auditing
Slide 12
Shadow Copy a low-cost way to recover from many file-related
accidents caused by human error Use to create copies of files or
folders that are stored on network file shares at pre-determined
time intervals issues that need to be considered when implementing
shadow copy Configuring shadow copy
