Hi
We have many of our employees who worked from home. So all our employees
use PCs supplied by the organisation and these PCs are installed with
approved software and updated frequently. They also have Pointsec on it.
Still there is no 100% protection from employees downloading stuff from
the Internet. That is where the information security policy and
awareness training comes in so employees are aware of the risks of
downloading and misusing the laptops.
Hope that helps.
Regards
Jessie.

Well, like everything else in the security space, the answer is "it all
dependes";)
One of the first things I tell clients when they start talking about a
VPN is that they are extending their network out to the VPN endpoint.
Now that home desktop is on your network. If that home desktop has a
worm, guess what, that worm is now on your network and if it can find
one machine that's vulnerable, then you have two worms. What if that
home computer has some kind of remote management software
installed...like Back Orifice? You're probably a little short-staffed,
right...well, now you have help;)
The solutions are all over the place. If you have a Cisco VPN, then the
remote management problem is turned off by default with their split
tunnel feature. It forces all traffic through the tunnel. There are
also clients that will force a virus scan of the workstation and force
other policy changes. You can also put some restriction at the VPN
termination point so that your VPN clients are restricted in what they
do. There are all kinds of solutions but it depends on what you're
running. You're started down the right path...VPNs can be scary!

Hi there,
I just wanted to put this out there. How secure is VPN.
Meaning, if my users take home the client and install it on their
desktop at home, and connect to the corporate network and production
network, wheat are we really looking at. Are they secure or not.
Two factor authentication would only help the authentication
purpose and to protect the user name and password ?
How about restricting them to access, and how about worrying
about their home computer that can be effected.
Has anyone been through this. Any one give home users a list of
requirements that they must have before vpn can be offered to them ?
Should there be some type of desktop policy installed on their
home computer, just to protect the company network ? Any help and
guidance would be great
Regards,
Sohail
