For more than two decades, Microsoft Active Directory (AD) has been the de facto method organizations use to authenticate and authorize users for access to computers, devices, and applications within a company’s network. Most companies still rely on it and have further extended its reach into the cloud by synchronizing their on-prem AD with the Microsoft Azure AD to allow proper SSO to cloud-applications by their users. AD is celebrated for its extensive compatibility with various applications and Windows editions, but that compatibility comes with security downsides.
Compromises of Active Directory can occur as an entry point leading to a further attack or can arise at various other points along the kill-chain following an initial compromise via some other mechanism. Even in cases where a compromise is gained following an attack on applications or infrastructure directly, it is frequently infeasible for an attacker to progress further without elevating privileges, making Active Directory a primary target in an overall breach strategy.
It is therefore important that Active Directory defense tools are paired with a wider Zero Trust and XDR approach to provide full visibility over organizational infrastructure, enabling security teams to accurately identify the point of origin of an attack, and to perform the containment and remediation actions required to neutralize and prevent reoccurrence of an attack.
Join Principal Technologist, Guido Grillenmeier, to discuss AD access points used in recent cyberattacks, security risks to watch for in managing AD with Azure AD, how to look for warning signs that AD has been compromised and steps to take in the event of an attack.
