Choosing the encryption type
You will want to consider a number of encryption types.
File encryption: File
encryption means that individual files are encrypted with a password.
This type is appropriate when sending a confidential file over an open line,
for example Internet Mail. This method works for small amounts of data, but becomes too unwieldy as the volume of data increases. Directory
encryption: This encryption type is
appropriate in networks to prevent access from users
which have rights to read other users' data. It may also
be useful for protecting data on diskettes or a local hard disk in the absence of other methods of security.
Master Boot encryption: This
encryption type allows you to hide the partition data
of the computer. This ensures that no-one can gain access to the hard disk after booting from diskette. The data itself, however, is
unencrypted, and can be read using a low-level tool
for reading sector by sector. Many system viruses can damage
Master Boot encryption, making it necessary to partition and reformat the
disk from scratch, depending on how the encryption is performed.
Full hard disk encryption: This
encryption type encrypts every single sector on the
entire disk. Even when a low-level tool is used from a startup diskette, no meaningful data can be read.
COM port encryption: This
encryption type is designed to protect communication
using a modem however, it has been superseded by hardware solutions
built-in to firewalls or modems.
LPT port encryption : A
combination of software and hardware will need to be used
to encrypt data dent to the printer. Some solutions automatically encrypt print data, with hardware connected to the printer to ensure
that what is printed makes sense. The possibility ofmonitoring the printer cable
is the reason why some people need this solution.
