Recently, the cybersecurity agencies of the Five Eyes Alliance countries jointly released the "Catalogue of Detection and Mitigation Activities"（Active Directory）Leakage "Guide，Intended to help identify and alleviate MicrosoftActive DirectoryThe threat of leakage.

Five Eyes Alliance（Five Eyes Alliance，FVEY）It is composed of the United States, United Kingdom, Canada, Australia, and New ZealandFive English speaking countriesFormed intelligence sharing organization，Member states jointly respond to various security threats through shared intelligence.hisHistory can be traced back toWorld War IIperiod.

And this releaseActive DirectoryActive Directory is a directory service provided by Microsoft that is used to centrally store and manage information about users, computers, applications, and other resources in a network, including user accounts, computers, printers, and shared foldersThePassword policies, etc. Implementing functions such as user authentication, access control, and policy implementationWindowsCore components of network environment，Its safety is crucial.

This guide elaborates in detailActive DirectoryWhy is it easy to become a target for attackers. Among them, the looseness of default settings, the complexity of permission relationships, support for old protocols, and the lack of effective tools for diagnosing security issues are all contributing factorsActive DirectoryAn important reason for being vulnerable to attacks. Once attackers successfully exploit these weaknesses, they may have the potential to take control of the entire enterprise network, which could lead to serious consequences such as sensitive data breaches, system crashes, etc，This will lead to large-scale and costly recovery and remediation efforts.

To reduce this intrusion risk, the guidelines provide specific recommendations. Firstly, organizations should ensure the security of privileged access. Secondly, organizations should adopt a hierarchical model to manage access permissions, such as Microsoft's enterprise access model, to ensure that users at different levels can only access the information and resources they need.

In addition, the guidelines emphasize the importance of regular audits and monitoring. Through regular auditsActive DirectoryBy configuring and accessing logs, organizations can promptly identify and respond to potential security threats. Meanwhile, by utilizing advanced monitoring tools and technologies, organizations can monitor network traffic and abnormal behavior in real-time, enabling rapid response and prevention of attacks.

The release of this guide not only helps organizations and institutions better identify and mitigate the threat of activity directory leaks, but also promotes international cooperation and communication in the field of cybersecurity，Jointly enhance the level of network security and protect critical infrastructure from attacks and damage.
