How does pgp shredder work

PGP Shredder completely destroys files and folders that you delete so that even file recovery software cannot recover them. When you delete a file using the Recycle Bin on Windows systems or Trash on Mac OS X systems , it is not actually deleted; just the directory information pointing to it is deleted.

PGP Shredder, however, immediately overwrites file's data multiple times. The Symantec Encryption Management Server provides central administration of encryption applications, creation and delivery of configuration policy, reporting and logging, and management of PGP private and public keys.

The biggest problem with Symantec Drive Encryption is even though the data on your hard drive is encrypted, after you log in and unlock the encrypted disk, your data is freely accessible. Making sure that everyone uses a login password and has that password activated when the computer wakes up from sleep or the screensaver can help with that problem.

However, on Windows, if you use Hibernate rather than Sleep , when your computer turns itself off, Symantec Encryption Desktop will protect your computer when it wakes. But not all Windows computers support or are set up so that they can Hibernate. To tell whether yours is, check to see whether Hibernate is a Shutdown option in the Start menu.

Even if it isn't, you might be able to turn it on. Search in Window's Help and Support for "hibernate" for more information.
