Network Security Attacks

Network security attacks aren’t some theoretical concept that can be put into the background and dealt with later, you know like the IT strategy document you’ve always been meaning to write.

Attacks of various types happen every day out in the wilds, on networks just like yours.

The recent attacks perpetrated against SCO over the past month or two hasn’t happened in isolation. In order for such a huge denial of service (DoS) attack to take place, literally thousands of networks worldwide must have been compromised. The people who perpetrate such attacks don’t use their own bandwidth. Using your own network would mean that they’d be caught pretty quickly. It doesn’t take long to tie an IP address to a name and address.

Many people believe that network security attacks are things that happen to somebody else. Well, they don’t. Every day we get a number of trojan emails, so we are under daily attack. You probably are too. Trojan emails are network security attacks just the same as the recent SCO DoS attack.

So, you’ve heard the bad news, we are under a constant stream of network security attacks. But, there is some good news, if you take sensible precautions you’ll probably be OK.
