AD Health & Security Check-up

As the Identity and Authentication source of most Enterprises, Active Directory is the backbone of local and federated authentication. Coupled with the prevalence of Cloud computing, organizations are depending more-and-more on federated authentication and expanding their Active Directory into the Cloud.

NetbiosSMB Missing Binding

While investigating the demise of NetBIOS and how to fully remove it from a network I came across and interesting observation.

The Case of the Four Folders

A client recently called in with an interesting problem. When users would create a new folder on a network share, four folders would appear instead of one. Even more interesting is that this was only happening for those users when connecting to the share from a Windows 10 workstation. The same user accessing the share from Windows 7 would only create a single folder.

Domain Permission Auditing with BloodHound

BloodHound uses graph theory to reveal the hidden and often unintended relationships within an Active Directory environment. In short, it analyzes group membership, GPOs, permissions, and currently logged-on sessions to visually displays links between objects in order to identify misconfigurations and easy paths to compromise. This tool is not for analyzing the permissions on a single server, but rather for identifying the path of least resistance to gaining elevated Domain permissions.

Installing Prometheus Docker Image on Debian 9

In preparation for an upcoming post, I recently dove into my notes on installing the Prometheus monitoring server. My last time setting up Prometheus was on an Ubuntu server and the repository version was at least the same major revision version as the current release. This time I’m installing on Debian 9 and currently the latest Prometheus version is 2.3.2 while the Debian repository is offering 1.5.2. That’s unacceptable. While the sid repository does contain 2.3.2, I decided to take the opportunity to deploy in a cleaner (and less permanent) manner through Docker. Prometheus is well supported in Docker environments and it gave me an opportunity to brush up on my container deploying skills.
