Going passwordless with Window Hello for Business and SCRIL

…or SCRIL in a hybrid environment. What could possibly go wrong? Way before the term “passwordless” was used by Microsoft to promote the use of alternative authentication methods besides a password there already was a way to go passwordless. In Active Directory there is a feature called SCRIL to achieve exactly this. SCRIL which is short for “Smart card is required for interactive logon” is an effective way to prevent any interactive sign-in to a domain joined machine using a password for the user that holds this attribute.

Sentinel Pester Framework

When you work with one or multiple Microsoft Sentinel workspaces you may find it necessary to not only deploy Analytics rules and other configuration artifacts using a version controlled source control (CI/CD) to limit human error and enforce consistency. But you might also want to independently verify your deployment on a regular basis. I certainly did and set out to write a test driven solution.

From on-prem to Global Admin without password reset

While working on another blog post I looked at different lateral movement paths an attacker can use, when she has compromised the Entra ID (Azure AD) Connect server.

The YAML format is mostly used to distribute Analytics Rules between people. All Analytics Rules you will find in the official Sentinel GitHub repo and others out there are offered in this format. The ARM format is what you need to deploy the Analytics Rules when using a pipeline or even if you want to import them using the UI in Microsoft Sentinel.

Prevent phishing based on domain registrations

Business email compromise and phishing are just two of the threats sent to hundreds and thousands of email inboxes around the world every day. As defenders, we use various tools and methods to limit the delivery of these emails to the intended target. In most cases, the attackers start by registering a domain that closely resembles the target company’s own domain name, or simply include the company name in the domain (e.
