Gary, That is not true. The requirement for scanning for (and dealing with) unauthorized APs or wireless devices is applicable to any physical location that has a part of the CDE (Cardholder Data Environment). Whether you have a wireless network and whether that wireless network is in or out of scope for PCI DSS you are still required to scan. There are a number of other wireless requirements if your WLAN *is* in scope that you can avoid if you can move it out of scope but this is not one of them. Taras, That requirement is focused on rogue detection and mitigation. If your WLAN can be moved out of scope for PCI (using a stateful firewall) then you are only required to scan for rogue devices. You can either do walk-around scans using something like kismet or NetStumbler or you can invest in a system with distributed sensors that can scan for the rogue devices all the time. In theory you could build this with low cost sensors running kismet and syslog and watch/filter the logs in a central location. You'd need a way of filtering out the known neighbors and internal devices and set up something to alert you, etc. I think you'll find that it is a lot less "free" than you would hope. -J On 4/23/09 2:20 PM, "Gary Everekyan" <Gary.Everekyan () consumerinfo com> wrote:
You can bypass the requirement if the WIFI Does NOT in any way transmit or connect to PAN data. If the Wireless network does not transmit PAN data and is segmented from the wired network with VPN FW ACL etc. than your WIFI is out of scope.

There is requirement in PCI DSS v.1.2: "...11.1 Test for the presence of wireless access points by using a wireless analyzer at least quarterly or deploying a wireless IDS/IPS to identify all wireless devices in use..." I made some research for open source wireless IDSs and results are not good. I found some articles about using together Kismet and Snort but it looks like not best soliution. Air Snort project is dead. What wireless IDS/IPS (especially opensource/free) do you use? -- Тарас Иващенко (Taras Ivashchenko), OSCP www.securityaudit.ru ---- "Software is like sex: it's better when it's free." - Linus Torvalds
