GIAC Security Essentials Certification (GSEC) Practice Test

Implementing two-factor authentication is a highly effective way to enhance a group's security permissions in Active Directory. This method involves requiring users to provide two different forms of verification before gaining access to sensitive systems or data. By adding this extra layer of authentication, organizations significantly reduce the risk of unauthorized access, even if a user's password is compromised.

This is particularly important in environments where sensitive information is managed because it ensures that access is granted only when both the password and a second form of verification, such as a code sent to a mobile device or a biometric scan, are presented. This level of security not only protects the accounts of individual users but also bolsters the security posture of the entire group, making it much harder for attackers to gain access even if they have knowledge of user credentials.

Other options do not achieve the same level of security enhancement. While limiting passwords to seven characters weakens password strength, assigning higher-level permissions directly to the group could lead to excessive privileges and potentially create security vulnerabilities. Using a single global group for all permissions can also result in improper access control and an increased risk of unauthorized access to critical resources, as it does not differentiate between the necessary levels of access for different users within the group.
