״Defenders think in lists, attackers think in graphs," said John Lambert from Microsoft, distilling the fundamental difference in mindset between those who defend IT systems and those who try to compromise them. The traditional approach for defenders is to list security gaps directly related to their assets in the network and eliminate as many as possible, starting with the most critical. Adversaries, in contrast, start with the end goal in mind and focus on charting the path toward a breach. They will generally look for the weakest link in the security chain to break in and progress the attack from there all the way to the crown jewels. Security teams must embrace the attacker's perspective to ensure their organization's cybersecurity defenses are adequate. Drawing an analogy to a daily life example, the standard way to defend our house from intrusion is to ensure all the doors are locked. But to validate that your house is protected requires ...

Cybersecurity isn't just another checkbox on your business agenda. It's a fundamental pillar of survival. As organizations increasingly migrate their operations to the cloud, understanding how to protect your digital assets becomes crucial. The shared responsibility model , exemplified through Microsoft 365's approach, offers a framework for comprehending and implementing effective cybersecurity measures.  The Essence of Shared Responsibility  Think of cloud security like a well-maintained building: the property manager handles structural integrity and common areas, while tenants secure their individual units. Similarly, the shared responsibility model creates a clear division of security duties between cloud providers and their users. This partnership approach ensures comprehensive protection through clearly defined roles and responsibilities.  What Your Cloud Provider Handles  Microsoft maintains comprehensive responsibility for securing the foundational eleme...

Attackers are increasingly making use of "networkless" attack techniques targeting cloud apps and identities. Here's how attackers can (and are) compromising organizations – without ever needing to touch the endpoint or conventional networked systems and services.  Before getting into the details of the attack techniques being used, let's discuss why these attacks are becoming more prevalent.  SaaS adoption is changing the make-up of company IT  The SaaS revolution and  product-led growth  have had a huge impact on the structure of company networks, and where core business systems and data reside.  Most organizations today are using tens to hundreds of SaaS applications across business functions. Some are entirely SaaS-native, with no traditional network to speak of, but most have adopted a hybrid model with a mixture of on-premise, cloud, and SaaS services forming the...
