When investigating alerts related to domain dominance, what specific aspect is crucial to focus on to understand attacker access maintenance?

Focusing on new accounts added to sensitive groups like Domain Admins is crucial when investigating alerts related to domain dominance because these accounts often serve as entry points for an attacker seeking to maintain access within a network. Domain Admins have extensive privileges, and any unauthorized addition to this group indicates a significant security concern. Attackers frequently create their own accounts or compromise existing ones to establish persistence within the domain, allowing them to execute malicious actions undetected.

By closely examining changes in group membership, especially those that elevate privileges, security analysts can identify potential malicious activities aiming to strengthen the attacker’s foothold. Consequently, tracking such alterations is fundamental in understanding the methods used by attackers to maintain access, elevate privileges, and execute further exploitation within the environment.

Other aspects, such as updates to antivirus definitions, traffic patterns, or changes to firewall rules, while important in the broader context of security monitoring, do not directly point to the establishment and maintenance of attacker access in the same specific manner as changes in sensitive group memberships.
