[comp.protocols.tcp-ip] IP access control

hal@GATEWAY.MITRE.ORG (Hal Feinstein) (02/25/89)

Who knows if  anything was/is/will be done to permit what DoD people
call "discretionary" access control at the IP level. Forms include
"filtering" based on host identity (address), host membership in a 
discretionary access control group, member of a subnet (perhaps via 
the IPSO and an RSA-like certificate).

I'm told that the new thing for all sorts of access control  problems is 
RSA-like certificates. Hope we can stand the overhead.

I should have added "discretionary access control performed by the
host IP server."  A few well designed gateways have such filtering, 
some quite  elaborate; however, what about host based software.

The IP security option carries "labels", some of which can be used for
access control and others which are  "advisory."  Does anyone know if 
any product will have a clean mechanism for passing these advisory labels
up to an application which can make use of them?

I haven't been particularly following this, but I know that Deborah
Estrins Autonets Task Force has been thinking about this stuff.
In particular, she has done some work on what she calls VISAs
which are used to authenticate IP-level packets.
