This
is one important step in increasing the dependability of your PC. There are
many things to be taken care on this factor. However a detailed explanation
is available at our PC Security Guide..
There are many issues with not keeping the PC secure
with all the OS patches, antivirus, antispyware, and firewall programs.
Following are some of those dangers.
 | It is dangerous for the data. |
| Your private data like user name, password may be
stolen. |
| System can become unstable and hang frequently etc.. |
Hence the dependability rises with better security.
There is no such thing as 100 percent secure PC. However common measures
like antivirus, Firewall, Antispyware are essential to be setup and running.
Encryption in Windows XP.
Encryption deal with another aspect of
keeping the PC data secure. if you encrypt a folder, that folder will become
inaccessible for another user with trying to access with a different user name.
You can use Encrypting File System (EFS) to:
|
Encrypt data
|
|
Access encrypted data
|
|
Copy, move or rename encrypted data
|
|
Decrypt data
|
Benefits
of encryption.
If you have a laptop computer and you
have lost it, if you have encrypted your files in windows XP, even if the
thief connects its hard disk to another PC and tries to retrieve its files,
it would not be possible to do so.
Encrypting data:
The default configuration of the Encrypting File System (EFS) requires no
administrative effort--users can begin encrypting files immediately. EFS
automatically generates an encryption key pair for a user if one does not
exist.
EFS can use either the expanded Data Encryption Standard (DESX) or
Triple-DES (3DES) as the encryption algorithm.
Encryption services are available from Windows Explorer. Users can also
encrypt a file or folder using the command-line function cipher. For more
information about the cipher command, type cipher /? at a command-line
prompt.
Privileges (Rights)
Most people may not be aware about this
important feature in windows XP and other OS's. You could create a user and
set his privilege in such a way that he does not have all the rights to a certain
folder of yours. However you have to be administrator to effectively
implement this policy. Otherwise user who is administrator can override your
settings.
Also NTFS based file system is
recommended for this to function well as FAT file system does not have much
option with regards to user rights. For more information please consult you
windows XP help pages.
