Some organisations that thought they had protected against W32/Blaster got a nasty surprise when roaming laptops brought the worm in, bypassing their firewalls. When the Blaster outbreak began, some organisations wisely checked that their firewall was blocking the ports it uses, but then made the mistake of becoming complacent and delaying the patching of computers inside - why hurry, they thought, when the firewall stops Blaster getting in? A rude awakening was in store: an unprotected laptop can be infected when it is outside, and "sneakernet" carries the laptop with worm into the office. Complacency is replaced by frantic activity to control the internal outbreak.
"Don't forget about the laptops when you are sorting out your computer security," reminds Graham Cluley, senior technology consultant at Sophos Anti-Virus. "It is because they are not always connected to the network that administrators need to be extra vigilant about making laptops as impenetrable to viruses as possible."
Sophos Remote Update provides an easy way for remote workers (such as laptop users or employees based at their homes) to be kept up-to-date with their virus protection. Remote Update keeps Sophos Anti-Virus up to date on an end-user's computer via a website or network connection provided by their employer. It is ideally suited to employees of organisations who are infrequently, or never, connected to the main company network, but who do connect to the internet from time to time.
