| Q. |
What
is the "Entire Computer" Application Entry? |
|
A. |
The
term "Entire Computer" references everything on your machine,
as it pertains to whichever table you are looking at. For example,
in the Application/File Tab, the Entire Computer entry represents
all applications on your machine, such as excel.exe, winword.exe,
etc. This entry is
the overriding entry unless an application is defined in the
table.

| Q. |
What
is c:\[0] and c:\[1]? |
|
A. |
These
two represent the heart of any hard drive, the File Allocation
Table (FAT) and the Boot Sector. They are defaulted as Read-Only
and should not be tampered with, except on rare occasions. |
| Q. |
What
is that Key at the end of each column? |
|
A. |
This
key represents a Password. If this column is checked, then to
modify any attribute in that entry, the user must know the
password. For example, if the Entire Computer Password Column is
checked, then to toggle the state of the Execute column, the user
would have to know the password. This allows critical entries to
be protected from change, except by the end-user who knows the
password. |
| Q. |
What
is an "Important" Attribute? |
|
A. |
The
"Important" feature allows the user to Encrypt and Backup a
particular file. The encryption is a Private Key, 64-bit,
encryption algorithm. After the file is successfully encrypted,
the file is then backed up w/the .cyi (Cytlok Important),
retaining it's original extension as well, and then the original
file is deleted. The purpose of backing up the file with a
different extension is that it adds another layer of security by
keeping the file from being opened up, and accidentally saved,
from the original viewer, etc. For example,
if
the user declares the spreadsheet, 'account.xls' as Important,
then the file is encrypted and backed up with the .cyi extension
and the original file deleted. So the new Important filename is 'account.xls.cyi'.
At a glance, the user can tell that the file is a Cytlok-encrypted
version of a file called 'account.xls'. However, the user cannot
open this file w/the spreadsheet tool, so there is minimal chance
the user will accidentally save (corrupt) an encrypted file.

| Q. |
What
is a Port? |
|
A. |
A
port represents a channel for information (data) to flow from/to
your computer via a TCP/IP connection, which is typical of the
Internet. Each type of service requires a different port. For
example, if the user is browsing the Web, via http, then he/she
has connected to port (channel) #80. |
| Q. |
Why
should I care about "incoming "and "outgoing"
ports separately? |
|
A. |
Typically,
the end-user client should only worry about "outgoing"
ports and not "incoming ports. The reason for this is that an
end-user client machine usually makes an outgoing connection to a
server somewhere on the network or Internet. If the machine is
acting like a server, i.e. sitting and waiting for another
computer to set up an incoming connection, then the user would
have to set up the "incoming" port appropriately. When
adding an application to Cytlok, each port’s
"incoming" attribute is 'disallowed' by default. |
| Q. |
I
hid a file, but I can still see it, what is wrong? |
|
A. |
If
this is the case, you have the file defined for more than one
application. For example, if you have the file 'readme.txt'
defined under Entire Computer and under Notepad.exe, and you
selected the Entire Computer readme.txt entry to be hidden, but
you did not select the Notepad.exe readme.txt entry as hidden,
then Notepad.exe can still see the file. The reverse is true as
well. |
| Q. |
I
want a certain file to be usable to a certain application and
nothing else, what do I do? |
|
A. |
Read
the above example. It turns out that Readme.txt, as set up above,
can only be used by Notepad.exe, and nothing else, because all
other applications (Entire Computer) cannot even see the file. |
| Q. |
I
know my application needs to open up certain ports to work
properly, but the problem is, I don't know which ports they are,
because they are not in the predefined Add Service Table. I don't
want to give it the "ALL" Ports allowed just so it will
work What do I do?font> |
|
A. |
This
is simple. It is recommended that after you first install Cytlok,
keep the Entire Computer attributes on, so it can execute and run
all applications and open up all outgoing ports. After you
successfully launch each application you typically run, take a
look at the Network Tracker log to see which ports an application
opens when launched. Then add that application and set up the
ports appropriately. If the predefined service table does not have
that port #, then use the Add New Service option to add it in.
Repeat this process for each application you use. You will soon
have Cytlok set up per your requirements. When you’re finished,
turn off the Entire Computer Execute and Entire Computer
"All" Ports and you have maximum Cytlok protection. |
| Q. |
Is
there an easy way to protect a set of files without adding each
file into the Cytlok database? |
|
A. |
It
is recommended you set up a special folder for your important
files. Add that folder to the Entire Computer Application and then
set up read-protected, write-protected or hidden as appropriate. |
