Understanding Active Directory Challenges

Active Directory (AD) presents significant security challenges for IT teams due to its complexity and the multiple interfaces it offers. Many IT professionals occupy diverse roles and rarely become experts in any specific area, which can lead to oversights or mistakes in configuration. For instance, administrative actions such as adding domain users to domain admin groups often occur without proper warnings or implications, making it difficult to notice and rectify these errors. This inherent complexity can lead to misconfigurations, which, if left unchecked, may culminate in security incidents or data breaches.
