Introduction
Novell®ZENworks®Endpoint Security Management (ESM) is designed to protect corporate data
assets, through a centrally managed tool called the Endpoint Security Client. The Endpoint Security
Client 3.5 is installed on Windows XP and Windows 2000 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.
For Windows Vista computers, see ZENworks Endpoint Security Client 4.0 User Guide.
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 9
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 3.5 are transparent to the user, after the network
environments have been defined. Occasionally, Endpoint Security Client 3.5 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),

10 ZENworks Endpoint Security Client 3.5 User Guide
novdocx (en) 13 May 2009
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 3.5, 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.

Endpoint Security Client 3.5
Overview
The ZENworks®Security Client secures computers from data invasion attacks at home, at work,
and while traveling, through the enforcement of security policies created by the enterprise Endpoint
Security Management (ESM) administrator. The firewall settings assigned at individual locations
are automatically adjusted when laptop users move from the corporate network to their home
networks or go on the road and log on to a public or open network.
Security levels are applied to various user locations without requiring user expertise or
understanding of network security, port configurations, hidden shared files, or other technical
details. Immediate information on which location and firewall setting the Endpoint Security Client
3.5 is in and which adapters are presently active or permitted is available by simply mousing over
the taskbar icon to view the Endpoint Security Client ToolTip (see Figure 2-1).
Figure 2-1 Endpoint Security Client ToolTip
The following sections contain additional information:
Section 2.1, “ESM Terminology,” on page 11
Section 2.2, “Logging In to the Endpoint Security Client 3.5,” on page 12
2.1 ESM Terminology
The following terms are frequently used in this documentation:
Locations: Locations are simple definitions that help users identify the network environment they
are in, provide immediate security settings (defined by the administrator), and permit the user to
save the network environment and change the applied firewall settings.
Each location is given unique security settings, denying access to certain network functionality and
hardware in more hostile network environments, and permitting broader access within trusted
environments. Locations define the following information:
How often the Endpoint Security Client 3.5 checks for a policy update in this location
The location management permissions granted to a user
The firewall settings that are used at this location
The communication hardware that is permitted to connect
How Wi-Fi connectivity and security is handled at this location

12 ZENworks Endpoint Security Client 3.5 User Guide
novdocx (en) 13 May 2009
At what level the user is permitted to use removable storage devices (such as thumb drives and
memory cards) and to use CD/DVD-RW drives
Any network environments that can help to define the location
Firewall Settings: Firewall settings control the connectivity of all networking ports (1-65535),
network packets (ICMP, ARP, etc.), network addresses (IP or MAC), and which network
applications (file sharing, instant messenger software, etc.) are permitted to get a network
connection when the setting is applied. Three firewall settings are included as defaults for ESM, and
can be implemented at a location. The ESM Administrator can also create specific firewall settings,
which cannot be listed here.
All Adaptive: This firewall setting sets all networking ports as stateful (all unsolicited inbound
network traffic is blocked; all outbound network traffic is allowed). ARP and 802.1x packets
are permitted, and all network applications are permitted a network connection.
All Open: This firewall setting sets all networking ports as open (all network traffic is
allowed). All packet types are permitted. All network applications are permitted a network
connection.
All Closed: This firewall setting closes all networking ports, and restricts all packet types.
Adapters: Refers to three communication adapters normally found on an endpoint:
Wired Adapters (LAN connections)
Wi-Fi Adapters (PCMCIA Wi-Fi cards, and built-in Wi-Fi radios)
Dial-up Adapters (both internal and external modems)
Also refers to other communication hardware that might be included on a computer, such as
infrared, Bluetooth*, FireWire*, and serial and parallel ports.
Storage Devices: Refers to external storage devices that can pose a security threat when data is
copied to, or introduced from, these devices on an endpoint. USB thumb drives, flash memory cards,
and SCSI PCMCIA memory cards, along with traditional Zip*, floppy, and external CDR drives and
the installed CD/DVD drives (including CD-ROM, CD-R/RW, DVD, DVD R/RW), can all be
blocked, permitted, or rendered to Read-Only at a single location.
Network Environments: A network environment is the collection of network services and service
addresses required to identify a network location (see Section 3.2.1, “Saving a Network
Environment,” on page 16).
2.2 Logging In to the Endpoint Security Client 3.5
If you are a member of the corporate domain, the Endpoint Security Client 3.5 uses your Windows*
username and password to log you in to the Policy Distribution Service (no pop-up window
displays). If you are not a member of the domain that the Policy Distribution Service is hosted on,
the Endpoint Security Client 3.5 prompts you for your username and password for that domain (see
Figure 2-2).

Enter your username and password for the domain, then click OK.
NOTE: It is not necessary to log in to the Endpoint Security Client 3.5 when the Endpoint Security
Client is running as Unmanaged. The ESM Administrator has a different method to deliver policies
to unmanaged users.

Using the Endpoint Security Client
3.5
The following sections contain additional information about actions that you can perform using the
Novell®ZENworks®Endpoint Security end-user application, the Endpoint Security Client 3.5:
Section 3.1, “Moving Among Network Environments,” on page 15
Section 3.2, “Changing Locations,” on page 16
Section 3.3, “Changing Firewall Settings,” on page 18
Section 3.4, “Data Encryption,” on page 19
Section 3.5, “Updating Policies,” on page 23
Section 3.6, “Viewing Help,” on page 23
Section 3.7, “Overriding a Password,” on page 23
Section 3.8, “Diagnostics,” on page 25
NOTE: The actions listed above can be restricted by the administrator at any location.
3.1 Moving Among Network Environments
Each network an end user travels to might require different security measures. The Endpoint
Security Client 3.5 provides security and protection in locations identified by available network
connections. The Endpoint Security Client 3.5 detects the network environment parameters and
switches to the appropriate location, applying the needed protection levels according to the current
security policy.
Network environment information is either stored or preset within a location. This allows the
Endpoint Security Client 3.5 to switch to a location automatically when the environment parameters
are detected.
Stored Environments: Defined by the user (see Section 3.2.1, “Saving a Network
Environment,” on page 16).
Preset Environment: Defined by the enterprise ESM Administrator through a published
security policy.
When the user enters a new network environment, the client compares the detected network
environment to any stored and preset values in the security policy. If a match is found, the Endpoint
Security Client 3.5 activates the assigned location. When the detected environment cannot be
identified as a stored or preset environment, the client activates the default Unknown location.
The Unknown location has the following presets:
Change Locations = Permitted
Change Firewall Settings = Not permitted
Save Location = Not permitted

16 ZENworks Endpoint Security Client 3.5 User Guide
novdocx (en) 13 May 2009
Update Policy = Permitted
Default Firewall settings = All Adaptive
The three adapter types, Wi-Fi, Wired, and Dialup are permitted in the Unknown location. This
allows the computer to interface peripherally with its network environment, and attempt to associate
a location policy as described above.
3.2 Changing Locations
At startup, the Endpoint Security Client 3.5 switches to the Unknown location. It then attempts to
detect the current network environment and to change the location automatically. If the network
environment is either unrecognized, or has not been preset or saved (see Section 3.2.1, “Saving a
Network Environment,” on page 16), the location must be changed manually.
If you cannot perform the following steps, your ZENworks Endpoint Security administrator might
have prevented you from changing locations manually.
To change a location:
1Right-click the Endpoint Security Client icon in the taskbar to display a menu of choices.
2Click the appropriate location.
3.2.1 Saving a Network Environment
A network environment needs to either be preset in the security policy or saved by the end user
before the Endpoint Security Client 3.5 can automatically change locations. Saving a network
environment saves the network parameters for the current location, and allows the Endpoint Security
Client 3.5 to automatically switch to that location the next time the user enters the network
environment. When applied in a Wi-Fi network environment, the Endpoint Security Client 3.5 will
LockOnTM to the single selected access point.
To save an environment:
1Right-click the Endpoint Security Client icon in the taskbar to display the menu.
2Click the location you want to change to.
3Right-click the Endpoint Security Client icon, mouse over the current location to display the
submenu, then click Save Network Environment to save the environment.

Using the Endpoint Security Client 3.5 17
novdocx (en) 13 May 2009
If this network environment was saved at a previous location, the Endpoint Security Client 3.5
asks if the user wants to save the new location. Select Yes to save the environment to the current
location and clear the environment from its prior location, or select No to leave the
environment in the prior location.
NOTE: The Save Network Environment function can be restricted by the ESM Administrator at any
location.
Additional network environments can be further saved to a location. For example, if a location
defined as Airport is part of the current policy, each airport visited by the mobile user can be saved
as a network environment for this location. This way, every time a mobile user returns to a saved
airport environment, the Endpoint Security Client 3.5 automatically switches to the Airport location.
3.2.2 Saving a Wi-Fi Environment
When users activate their Wi-Fi adapters, they might see dozens of available access points. A Wi-Fi
adapter might lock on to a single access point at first, but if too many access points are within
proximity of the adapter, the associated access point might be dropped and the wireless connection
manager could prompt the adapter to switch to the access point with the strongest signal. When this
occurs, current network activity is halted, often forcing a user to resend certain packets and
reconnect the VPN to the corporate network.
If an access point is saved as a network environment parameter at a location, the adapter locks on to
that access point and does not lose connectivity until the user physically moves away from the
access point. Upon returning to the access point, the adapter automatically associates with the access
point, the location changes, and all other access points are no longer visible through wireless
connection management software.
To save a Wi-Fi Environment:
1Open the connection management software and select the desired access point.
NOTE: Connection management software can be overridden by location when the ESM
security policy is set to manage your wireless connectivity.

2Specify any necessary security information (WEP or other security key), then click Connect.
3Complete the steps outlined in Section 3.2.1, “Saving a Network Environment,” on page 16 to
save this environment.
3.2.3 Removing a Saved Environment
To remove a saved network environment from a location:
1Right-click the Endpoint Security Client icon in the taskbar to display the menu.
2Change to the appropriate location.
3Right-click the Endpoint Security Client icon, then select the current location to display the
submenu.
4Click Clear Network Environment to clear the environment.
NOTE: This clears all saved network environments for this location.
3.3 Changing Firewall Settings
Each location can be assigned more than one firewall setting. Changing the firewall setting can open
or close networking ports and allow or disallow certain types of networking in a given location.
To change the firewall settings:
1Right-click the Endpoint Security Client icon in the taskbar to display the menu.

2Mouse over the current location to display the submenu, then click the selection to change the
firewall setting.
NOTE: The number of firewall settings available in a location is determined by policy.
3.4 Data Encryption
When activated by policy, the Endpoint Security Client 3.5 manages the encryption of files placed in
a specific directory on the endpoint and placed in removable storage devices.
The following instructions will assist you in using ZENworks Endpoint Security on the endpoint.
Section 3.4.1, “Managing Files on Fixed Disks,” on page 19
Section 3.4.2, “Managing Files on Removable Storage,” on page 19
3.4.1 Managing Files on Fixed Disks
Fixed disks are defined as all hard-disk drives installed on the computer, as well as any partitions of
a hard-disk drive. Each fixed disk on the endpoint has an
Encrypted Files folder placed at the
root directory. All files placed in this folder are encrypted, using the current encryption key. Only
authorized users on the computer can decrypt these files.
When saving a file, select the
Encrypted Files folder from the available folders on the desired
drive.
3.4.2 Managing Files on Removable Storage
Removable storage is defined as any storage device that is “connected” to a computer. This includes
(but is not limited to) USB thumb drives, flash memory cards, and PCMCIA memory cards, along
with traditional Zip, floppy, and external CDR drives, digital cameras with storage capacity, and
MP3 players.
When you are running ZENworks Endpoint Security, files stored on these devices are encrypted as
they are accessed by the operating system or the user. Files copied to the device are immediately
encrypted. When the removable storage device is connected to a computer not managed by the
ZENworks Endpoint Security system, the files remain encrypted and cannot be decrypted.
Encryption of removable storage occurs at the insertion of the device (see “What If I Don’t Want the
Device Encrypted?” on page 20). However, files added to an encrypted removable storage device on
another machine are not encrypted, and must be encrypted manually.
The following sections contain more information:
“Encrypting Files” on page 20

Encrypting Files
To encrypt added files on a removable storage device:
1Plug the storage device into the appropriate port on your computer.
2Right-click the Endpoint Security Client icon in the taskbar.
3Select Encryption from the menu.
4Click Encrypt RSD. This encrypts all files on the removable storage device with the current
encryption key.
The amount of time needed to encrypt the files depends upon the amount of data stored on the
device.
What If I Don’t Want the Device Encrypted?
When you insert a removable storage device, the Endpoint Security Client prompts, asking if you
want the drive encrypted, or if you prefer to remove it and not encrypt all files.
