Question and answers

This paper provides answers to commonly asked questions about the HP Sygate Security Agent and the

Symantec Embedded Security subscription service. Currently, the firewall in Symantec Embedded Security

is the same as in the HP Sygate Security Agent.

Overview

Q:

Are thin clients susceptible to viruses or worms?

A:

Server Based Computing with HP Compaq Thin Clients is, by nature, less susceptible to virus and

worm attack than a PC with Windows XP Professional. When compared to the traditional

unmanaged PC network model, the HP thin client computing model yields a less vulnerable,

segregated approach to computing with substantially better recovery time, while minimizing total cost

of ownership (TCO).

1.

With the HP thin client computing model, your exposure to virus attack on the thin client system is

less than a standard Windows PC. See the white paper titled “Thin Client Virus Vulnerability

Analysis” at

http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00595181/

c00595181.pdf

for more information.

2.

The HP thin client computing model utilizes PC blades and/or servers located in the data center.

You can protect and monitor these centralized devices more easily with centrally managed virus

and firewall tools. Compromised resources can be quickly taken offline, or recovered faster and

more cheaply than distributed PC resources.

3.

Since no user data resides on the thin client, there is no risk of user data loss due to a virus or

worm on the thin client.

4.

If a thin client’s image is compromised or corrupted, the recovery time is typically measured in

minutes instead of hours. You can often perform recovery with a simple reboot of the client.

Additionally, HP follows strict security-centric image design policies and uses the Enhanced Write

Filter to provides a more secure environment for thin-client computing. The Enhanced Write Filter

protects the thin client from undesired flash memory writes (the operating system and functional

software components reside in flash memory). If a thin client does become infected by a virus, a

simple reboot cycle clears the system RAM and returns the client to its original state from the protected

Flash memory.

HP believes the thin client computing model is an effective solution for the security conscious

enterprise. However, the Windows XP Embedded operating system may have vulnerabilities that can

be exploited by the increasingly sophisticated attacks on business networks. To provide further

protection for our customers, HP has partnered with Symantec to deliver industry leading protection

from worms, trojans and viruses.

Q:
