RE: 3DES [7:34756]
I heard it put very well, and wish I could attribute it but I don't recall the source: To paraphrase, it goes something like this: <> Think of what it is your company makes, does or sells ... or is planning on doing so in the future. ... and how it makes it and/or does it, how much it costs to do so, etc. ... and who it sells it to ... and for how much .. and where this money goes Think of what differentiates you from your competitors .. quality, quantity, unique products/information/processes, etc. Now think of what would happen to your company if your competition knew all of this. Granted - you can argue that this oversimplifies things a little bit, but it makes a point that will readily hit home with management if nothing else! Thanks!

Re: 3DES [7:34756]
A couple of questions regarding the original post and then some comments: It was unclear to me from the original post why you need the DES/3DES. Are you running end user VPN clients? Router-router tunnels? You need to consider the purpose of the encryption and the information it's intended to guard before deciding on the level. I've got some clients (law enforcement agencies, brokerage firms, etc.) where I don't take any comfort from 3DES. On the other hand, I've got some small business clients that use encryption for interoffice links that transfer non-sensitive/low sensitive information. For these guys, DES is plenty.

RE: 3DES [7:34756]
We deal with interfacing Alarm systems, both fire and security. 3Des would be needed so someone would have a hard time tripping alarms via the internet. I don't want to get out of bed at 3am, along with a lot of other people, fire, police, owners etc. Also we are writing Code, which programmers spend hours/days/weeks on. And we are getting patents, and writing code for the hardware. I think security is going to be much more important as time goes on. I am the extreme paranoid type, so I would rather take the safe route every time. I think if Enron had some hackers, and they deleted some data, it would only be doing them a favor at this point. -Original Message- From: Chuck Larrieu [mailto:[EMAIL PROTECTED]] Sent: Friday, February 08, 2002 11:07 AM To: [EMAIL PROTECTED] Subject: Re: 3DES [7:34756] The paranoid among us can think of other industries where industrial espionage might play a part.

I'm not sure when Cisco will incorporate AES, but it is already used in SSH2 and other products (can't think of any others of the top of my head). In fact, my company incorporates in AES into a client-server solution we offer. I've only read and heard good things about AES. - Sean -Original Message- From: Alex Lei [mailto:[EMAIL PROTECTED]] Sent: Friday, February 08, 2002 9:50 AM To: [EMAIL PROTECTED] Subject: RE: 3DES [7:34756] AES?
