Times change very quickly. It doesn't seem that long ago that the very worst that we had to worry about on the Internet was the occasional email hoax. Today, we need to be cautious of every dark shadow
So, what happened? The events of September 11, 2001.
What has changed? Nothing. The truth is that we should have always been more aware of the lack of security around us.
We need to get very smart about the way we secure the information that is essential to who we are and how we work.
We need to stop thinking like Boy Scouts and church choirs, at least when it comes to Internet security.
We need to stop unsafe practices, even by those who think they have some kind of inalienable right or public mandate to do exactly as they please. We need to shutdown spammers and rogue websites, no matter what political border they think gives them safe refuge. We could tolerate their idiosyncracies before 9/11; now, we cannot. We need to stop corporations and government agencies from sending proprietary format email attachments as a matter of routine. We need to educate political decision-makers about just how complex the security problem is.
In the meantime, since a broad solution to network security does not seem forthcoming, we need to do whatever we can do to protect our people, our clients, our employees, our businesses, our homes, our families, and ourselves. This will not be cheap; it requires commitment on the part of all defenders.
Increase group and personal awareness of security issues.
Keep your software up to date.
Install virus scan, spyblocker and firewall software.
If you are connected to the Internet via some kind of permanent link, put a router and/or firewall between you and the rest of the Internet.
If you use a wireless access point, lock it down.
