RE: Wireless security question

["Harshul Nayak" <harshul.nayak () patni com>]

Hello Marty,
have a well defined wireless security policy for your network
Make the User aware about the Security policies implemented, educate them ..

- Tell employees they own security and share the cost of security breaches.
- Explain to employees the risk of setting up access points (AP) without the
knowledge or consent of the network administrator (called Rogue Access
Points).
- When setting up Rogue APs, employees often fail to address security
settings, incorrectly assuming they are turned on.
- Implement a system where users know the names of the APs, and stress the
importance of connecting only to known APs.
- Educate users about the security risks of connecting wirelessly using
peer-to-peer networks.
- Warn users about the dangers of connecting in public or shared spaces
using ad hoc mode.
- Show users how to check security mechanisms on their PC and, if required,
enable them.

Implement Vigilant Security Policies
Without a policy requiring regularly scheduled security checks, you're
putting your network at risk for future security breaches.

-Develop a WLAN security policies and establish quarterly performance
objectives based on these policies.
- Regularly scan for rogue or unknown APs.
- Change default management passwords and SSIDs on APs.
- Implement the latest IEEE security specifications (currently 802.11i).

Hi gang!

Here is a question for you...

We have a secure network with no wireless
connections whatsoever.

One of our laptop came in with credentials to log
on to the network through the Ethernet cable BUT
the person had just added a wireless card to his
laptop.

This situation actually came up and the person
could see external wireless networks (from other
companies around our building) and access
Internet through there. Yeah I know they're
stupid, but it's the real world!

This seems like a potential threat for taking our
data out the back door.
Copy files accessed through our network to
another network and voilà! No trace at all of the
mischief.

We monitor internet access and block non-company
Email (Yahoo, Hotmail etc.).

Suggestions?

Thanks and Happy Holidays!

Marty!
