Firewall Protection in Windows PE (Windows Embedded Standard 2009)
Any time you connect to a network, you are vulnerable to network attacks, including viruses, worms, and attempts to access data on your device.
Windows PE 2005 includes Windows Firewall. Windows Firewall is enabled by default when you boot by using Windows PE. If you are using Windows PE from an earlier Windows XP Embedded version (prior to Windows XP Embedded with Feature Pack 2007) you should take other measures to protect your device. These measures include enabling other third-party hardware or software firewalls, and using anti-virus software.
