Holistic Enterprise Security

I participated in a brief discussion on Twitter regarding the Podesta email breach. I blame the DNC for the reach.

Clinton and Podesta were functionally using shadow IT. There really isn’t any excuse for not detecting it. So then what? Do you declare it unsupported or assess the risk and implement compensating controls?

How expensive is monitoring for a few dozen extra email addresses on HaveIBeenPwned?

These folks already have administrative assistants and likely physical security details. If your organization is willing to spend those resources, why can’t you spend some resources assisting with the secure configuration of personal devices?

To take it a step further, give them a SOHO router IT remotely manages. You can decide how comfortable the VIP and the organization is with the relationship. Are you just doing secure configuration? You can throw OpenDNS on it for ‘blind’ basic security.

In a Cisco environment, you can hand out 881 devices that automatically VPN back. The VIP can take home a hardware VOIP  phone. You can provision dedicated wireless for the VIP devices. The person won’t even have to worry about VPN in their home office.

Deception Technology?

Deception technology seems to be the latest buzzword. It was everywhere at Black Hat and now my favorite Gartner researchers are covering it.

I talked to the vendors at Black Hat. I can’t figure out what they are offering that I couldn’t give to an intern to deploy over the summer. I worked with an intern over a summer to deploy the basic technology.

My deception environment:

  • I reserved random IP space and assigned likely machine names in a couple segments of the network. If administrative cost is a concern for deploying a sensor, null it route it to the local router / switch and log traffic.
  • In the server space, I requested standard Linux and Windows systems following the IT standards. Throw standard software on them with default configs. Log the activity.
  • I created some honeypot DNS entries. Payroll, Mainframe, etc.
  • I had some honeypot accounts created in Active Directory following naming standards. I didn’t request the IT staff log in to some systems, that’s a clear deficiency in my setup. I should have requested the Oracle team create an extra account, the AD admins create an extra account, etc.

I didn’t get any confirmed malicious hits, but did catch some unexpected scanners. Printing services performed an unexpected/unplanned scan of the user environment, a system admin incremented system numbering in to my space, etc.
