Optimizing the NetWare Client Software
Improving Security
Effective Packet Signature Levels
The signature levels for the server and the client workstations combine to
determine the overall level of NCP packet signature on the network called
the effective packet signature level.
Some combinations of server and client packet signature levels might slow
performance. However, low-CPU-demand systems might not show any
performance degradation.
You can choose the packet signature level that meets both their performance
needs and their security requirements.
The following table shows the interactive relationship between the server
packet signature levels and the client workstation signature levels.
Examples of Using Packet Signature Levels
This section includes some examples of when you would use different
signature levels.

Example If an intruder gains access to any information on the
NetWare server, it could damage the company.
Solution The network supervisor sets the server to level 3 and all
client workstations to level 3 for maximum protection.
