Introduction
The Novell®ZENworks®Endpoint Security Client 4.0 is a client release to support Microsoft
Windows Vista with Support Pack 1 running in 32-bit mode. The Endpoint Security Client 4.0 uses
the ZENworks Endpoint Security Management 3.5 Server and Management Console.
Novell ZENworks Endpoint Security Management (ESM) is designed to protect corporate data
assets, through a centrally managed tool called the ZENworks Security Client. The ZENworks
Endpoint Security Client 4.0 is installed on Windows Vista enterprise computers and enforces
security policies written and sent down through the ESM management and distribution system. This
allows large enterprises and small businesses to create, deploy, enforce, and monitor computer
security policies on computers inside and outside of the corporate security perimeter.
The following sections contain additional information:
Section 1.1, “Security Enforcement for Mobile Computers,” on page 9
Section 1.2, “NDIS Layer Firewall Protection,” on page 10
1.1 Security Enforcement for Mobile Computers
Security is enforced both globally and by network location. Each location listed in a security policy
determines the user's permissions in that network environment and determines which firewall
settings are activated. The firewall settings determine which networking ports, network addresses,
and applications are granted network access and how that access is permitted.
Figure 1-1 ESM Adjusts Security Settings Based on the Detected Network Environment
Normal operations of the Endpoint Security Client 4.0 are transparent to the user, after the network
environments have been defined. Occasionally, Endpoint Security Client 4.0 protective measures
can interrupt normal operation; when this occurs, messages and hyperlinks display to notify the user
about the security policy, what protective steps have been taken, and refer them to additional
information to help correct the issue.

1.2 NDIS Layer Firewall Protection
In securing mobile devices, ESM is superior to typical personal firewall technologies that operate
only in the application layer or as a firewall-hook driver. ESM client security is integrated into the
Network Driver Interface Specification (NDIS) driver for each network interface card (NIC),
providing security protection from the moment traffic enters the computer. Differences between
ESM and application-layer firewalls and filter drivers are illustrated in Figure 1-2, “Effectiveness of
an NDIS-Layer Firewall,” on page 10.
Figure 1-2 Effectiveness of an NDIS-Layer Firewall
Security decisions and system performance are optimized when security implementations operate at
the lowest appropriate layer of the protocol stack. With the Endpoint Security Client 4.0 , unsolicited
traffic is dropped at the lowest levels of the NDIS driver stack by means of Adaptive Port Blocking
(stateful packet inspection) technology. This approach protects against protocol-based attacks,
including unauthorized port scans, SYN Flood attacks, and others.
It is recommended that you follow all operation and maintenance recommendations in this
document, in order to ensure that the endpoint security environment is protected.
