I think port security is what determines whether or not a box is allowed onto the network. If you know that all of your conference room jacks are patched into switch X blades Y-Z, then you apply security to those ports. If you have a *NIX box in a server room, you obviously drop the mcafee security requirement for that port. I havent read through the documentation but that's my guess. The corporate network security market is looking for a way to ensure that only machines with up to date security policies (AV, FW, IPS) are allowed on the network...with ways to distinguish printers, from workstations/servers... etc... -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Sean Donelan Sent: Tuesday, November 18, 2003 3:48 PM To: [email protected] Cc: [email protected] Subject: Re: Cisco, Anti-virus Vendors Team on Network Security On Tue, 18 Nov 2003 [email protected] wrote: > > Without the secret handshake Mac OS, Linux, Solaris and other > > operating systems will not be able to connect to a Cisco > > Self-Defending Network which limits its usefullness for ISPs. > > A *nix without a secret handshake is like a fish without a bicycle. > > Yes, viruses *are* theoretically possible on these platforms, but > let's be honest here - even if you included all of the platforms, > you'd only intercept another 1% or so viruses, tops. Well, if you let systems on the network without the secret handshake, what's to stop people from connecting Windows boxes with the "security" software disabled so it doesn't answer the "I'm Infected" question? Or the next virus can take over the Cisco secret handshake port and always answer "I'm Ok" when ever the network asks it a question. How does the Self-Protecting Network tell the difference between a non-infected Mac or Unix machine from a Typhod Mary Windows bo if you are depending on software on the system to answer the question? Yes, some level of security works when every obeys the rules. But the current problem ISPs have is not everyone obeys the rules. |
