Abstract

There are many forms of blindness, including perceptual or psychological forms where people fail to see what's right in front of them. Many organisations have this disability when it comes to their networks but the problem with this condition is that sufferers don't know they have it. Network blindness is the inability to make sense of network information. You might have some of the basics, statistics from your routers and switches, logs from your firewall. You might have some information from your IDS (if you have one). But it's all rather fragmentary and - not knowing the full picture - it's easy to jump to the wrong conclusions, or worse still, not know there's an issue in the first place. Dominic Storey of Sourcefire outlines the 10 most common forms of the condition. There are many forms of blindness, including perceptual or psychological forms where people fail to see what's right in front of them. Many organisations have this disability when it comes to their networks but the problem with this condition is that sufferers often don't know they have it.
