7MS #261: Blind Network Security Assessments

This week I had the fun opportunity to do a "blind" network security assessment - where basically we had to step into a network we'd never seen before and make some security posture recommendations. I've found that the following software/hardware is quite helpful for this type of assessment:

  • The PwnPulse helps a ton in scanning wired and wireless networks...and even Bluetooth! I've covered the Pulse in past episodes - check out part 1 and part 2.

  • Network Detective will do a ton of helpful Active Directory enumeration and point out potential red flags, such as:

    • Accounts that haven't been logged into for a long time
    • Accounts with passwords that haven't been refreshed in a long time
    • Privileged groups that need review (Domain Admins, Enterprise Admins, etc.)
  • AD policy issues (*warning: by default Network Detective only pulls back a few policies by default. Check out scripts such as my Environment Check to grab a dump of all GPOs.

  • Thycotic Privileged Account Discovery is a free tool that can crawl AD workstations and enumerate the local administrator accounts on each machine. It makes a good case for implementing LAPS.

7MS #31: Network Detective (audio)

Network Detective is a tool we’ve been using as kind of an addendum to our full security assessment. It gives some nice, plain-English Excel spreadsheets and Word docs that report on AD health and structure, PC inventory and open ports, AV clients that aren’t working right, and a whole lot more.

Most organizations I talk to have no idea where their privileged accounts are used across the network. I recently saw a demo of a solution called CyberArk, which seems to address that problem. Download: 7MS #30: Managing Privileged Accounts (audio)

7MS #26: The Importance of Training and Awareness (audio)

Training and awareness – specifically as it relates to infosec – is something companies can’t spend enough $ on. But from my experience, not enough of them are making this a front-burner priority.
