Entra ID Security Essentials

With the push of different cloud technologies, companies require a place to centrally manage authentication and authorization to cloud services. Entra ID can act as one of these places and - as an identity provider - fundamentally changes how users authenticate and access resources compared to traditional on-premises environments. Administrators and security personnel need to be aware of these changes as well as new challenges that come with these changes to effectively secure Entra ID.

What complicates things is that adversaries are also aware of these changes and show an increased use of tactics and techniques to exploit gaps – such as configuration vulnerabilities – in the existing cloud protection. CrowdStrike’s Global Threat Report 2024 shows that the number of cloud-conscious cases (where adversaries were aware of cloud access) increased by 110% year over year while successful intrusions into cloud environments increased by 75% year over year (2022 to 2023). This trend can also be seen in the ongoing focus of adversaries on identity-based and social engineering attacks (e.g., phishing) targeting account credentials, session cookies and tokens, as well as one-time passwords to gain legitimate access to Entra ID and other cloud environments.

This raises the relevant question: what can you do to protect your Entra ID users and the resources they access? This intensive two-day training aims to give you an overview over how Entra ID functions, how adversaries attack Entra ID, and how to protect against these attacks. Throughout the training we give you current, actionable recommendations to protect your own Entra ID tenant.
