Virus vulnerabilities, encounters, and impact The following graph depicts security vulnerabilities experienced by actual enterprise customers as sur- veyed by ICSA Labs for the years 1996 through 2002. The second graph contains the most vulnerable technologies as perceived by the enterprises surveyed in 2003 by EDC. The graphs illustrate a strong cor- relation between the actual occurrence of each vulnerability and its associated technology in an enter- prise. -

HP Thin Client response to vulnerabilities As the data in the previous section shows, the thin client computing model substantially reduces the likeli- hood that a thin client device will encounter a vulnerability as compared to a standard PC. The model also centralizes the enterprise’s most vulnerable technologies in the data center, where you can effectively... -

HP XPe thin clients, the Enhanced Write Filter (EWF) prevents permanent modifications (writes) to the con- tents of the system’s flash. Finally, the Internet browser is an optional feature on select HP thin clients. Selecting models without it or optionally removing it ensures a more secure environment. -

MS00-046 MS03-007 In addition to being a smaller target, the HP thin client XPe operating system contains an Enhanced Write Filter (EWF) that prevents damage to the local file system and its operating system files. The EWF protects the contents of the media by redirecting all the writes to a temporary virtual memory location. These writes are lost when the system is shutdown or restarted. -

Recovery time In the event of a virus attack or other security issue, the HP thin client computing model offers significantly shorter recovery time when contrasted with the traditional desktop model. If a thin client’s image is com- promised or corrupted, recovery time is typically measured in minutes instead of hours. Recovery usually involves a power cycle (1 minute), patch (5 minutes), or re-image (15 minutes) of the system. -
