A type of denial-of-service (DoS) attack that targets firewalls from a number of vendors including Cisco, Palo Alto and SonicWall was found to have resurfaced earlier this month. Unlike other DoS attacks that rely on pounding machine or network resource with large amounts of traffic, BlackNurse doesn't require much bandwidth at all. Researchers have shown that BlackNurse will work with less than 20Mbps of traffic and is effective even against large enterprise firewalls. For IT administrators who want to test for and mitigate against this kind of attack on their organisation, here are the the instructions.

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.

One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.
