New Guidance on Detecting and Mitigating Active Directory Compromises Released by CISA and International Partners

The Cybersecurity and Infrastructure Security Agency (CISA), in collaboration with the Australian Signals Directorate's Australian Cyber Security Centre (ASD ACSC) and other international partners, has released a comprehensive guide on detecting and mitigating Active Directory compromises.


Active Directory (AD) is a critical component of enterprise IT networks, providing authentication and authorization services. However, it is also a prime target for malicious actors seeking to gain unauthorized access to sensitive information and systems.


The newly released guide outlines strategies to mitigate the 17 most common techniques used by adversaries to compromise Active Directory. These techniques include exploiting vulnerabilities, leveraging stolen credentials, and conducting phishing attacks. The guide provides actionable recommendations for organizations to enhance their security posture and protect their AD environments.


Key highlights from the guide include:

  • Early Detection: Implementing monitoring and detection mechanisms to identify suspicious activities and potential compromises early.

  • Access Control: Strengthening access controls to limit the potential impact of a compromise and prevent unauthorized access.

  • Incident Response: Developing and practicing an incident response plan to quickly and effectively address any detected compromises.


The guide was developed in cooperation with international partners, including the National Security Agency (NSA), the Canadian Centre for Cyber Security (CCCS), and the New Zealand National Cyber Security Centre (NCSC-NZ). This collaborative effort underscores the global importance of securing Active Directory environments and the shared commitment to enhancing cybersecurity.


Organizations are encouraged to review the guide and implement the recommended strategies to safeguard their Active Directory infrastructure. By doing so, they can better protect their critical systems and data from malicious actors.
