Comment 1: 20 hour exception is too long for secure sessions dealing
with identification and financial information and services

Original Comment:

To protect our clients we have time limit of 15 minutes if the user
does nothing, the session to our netbank is automatically closed.

This is utterly important especially for users using public computers
e.g. in libraries.

The extend rule might work in this case but I'm not sure we want to
advertise the security features that much. E.g. in the case of public
computers drawing the attention of possible bystanders..

Proposed Change:
Security exception: In order to prevent mishaps, identification and
financial services can close session after a short time(5-20 min) if
the user is idling.

Response from Working Group:

You are correct that the "extend" option would be the proper one for
the situation you describe. Your 15 min time limit is intended to
close down the terminal if someone leaves the terminal, but not to
close down the terminal if someone is still there. So, if your
application checks to see if people are active - and asks them if they
need more time if the terminal goes inactive - you could actually
decrease the 15 min time (from last keystroke for example) to
something much smaller and still meet this provision while providing
all users with time they need to complete the transaction.

Instead of closing down at 5-20 min, just back up 20 seconds (to 5 to
20 min minus 20 seconds) and ask the user if they need more time. If
they do not respond, you can still close down at 5 min (or 20 min) and
you will shut down the connection at the exact same time - and conform
to this provision as written.
