Wireless Communications Management With McAfee DLP

Hi,

I have difficulties to create a McAfee DLP Policy which allow to manage the wireless communications.

I'll explain :
In my company, it is possible to connect to the Enterprise Network by using a wireless or wired access.
We have a dedicated subnet for the workstations that connect to the Enterprise Network using a wireless access.

My goal is to block all wireless communications only when my laptop connected to the wired Enterprise Network.

In my McAfee DLP Policy (Windows Client Configuration) > Corporate connectivity settings > Corporate Network Detection, I selected the "by testing connectivity to any of the following corporate servers"
option and added a corporate Server Address + Port

In my McAfee ENS Firewall Policy > Rules, I created a dedicated group for the "Enterprise wifi access" and added a firewall rule which block access to the corporate server.

I successfully tested My McAfee ENS Firewall Policy.

When I apply my McAfee DLP Policy (+ My McAfee ENS Firewall Policy) and I try to access to the Enterprise Network (wifi), after a few seconds, McAfee DLP block wireless communications.
I have the feeling that the DLP Connectivity test bypass my McAfee ENS Firewall Policy.

is this possible ?


Is it possible with McAfee DLP to :

- Block all Wireless Communications when my laptop connected to the Enterprise network (wired)

And

- Allow the wireless communications for other situations (External Nomadism or Connect to the Enterprise Network by using an Enterprise Wifi Access).


Best Regards,

Thomas

Re: Wireless Communications Management With McAfee DLP

I would suggest to go with Network communication protection rule.

specify the network attributes you want the rule to filter on.
Each attribute can only be added once to a rule.
• Source IP Address — Specify an IP address or an IP address and netmask.
• Destination IP Address — Specify an IP address or an IP address and netmask.
• Source Port — Specify a port in the range of 0-65535.
• Destination Port — Specify a port in the range 0-65535.
• VLAN ID — Specify the VLAN tag ID. Untagged traffic uses the default 4095 ID.
• Transport Protocol — Choose from TCP or UDP.
• Application Protocol — Select the protocol you want the rule to match on.
• SOCKS Encapsulation — Select whether the traffic is encapsulated.
• Sender Email Address — Specify the sender email address to match against.
• Recipient Email Address List — Specify the recipient email address to match against.
• URL — Specify the HTTP URL.

Example : IP range of wifi will 192.167.x.1 to 255. Select the source IP range & create definition list for same.

One more thing, for McAfee DLP Policy (Windows Client Configuration) > Corporate connectivity settings --> This setting will be used to connect the ePO server (either by ePO server or IP address:port for ePO server communication).
