Recommended Signature Levels
The default NCP Packet Signature level is 1 for clients and 1 for servers. In
general, this setting provides the most flexibility while still offering protection
from forged packets. Following are some examples of situations requiring
different signature levels.
For information on implementing NCP Packet Signature, see “Implementing
NCP Packet Signature” on page 73.

Situation Example Recommendation
All information on the server is
sensitive.
If an intruder gains access to any
information on the NetWare
server, it could damage the
company.
Set the server to level 3 and all
clients to level 3 for maximum
protection.
Sensitive and nonsensitive
information reside on the same
server.
The NetWare server has a
directory for executable programs
and a separate directory for
corporate finances (such as
Accounts Receivable).
Set the server to level 2 and the
clients that need access to
Accounts Receivable to level 3.
All other clients remain at the
default, level 1.
Users often change locations and
workstations.
You are uncertain which
employees will be using which
workstations and the NetWare
server contains some sensitive
data.
Set the server to level 3. Clients
remain at the default, level 1.
A workstation is publicly
accessible.
An unattended workstation is set
up for public access to
nonsensitive information, but
another server on the network
contains sensitive information.
Set the sensitive server to level 3
and the unattended client to level
0.
