AD groups enable network administrators to give users and other entities access to assets within the organizationÍs network. If AD groups are mismanaged, the sensitive data stored in the network can be compromised.
Most cybersecurity incidents could have been averted if IT security teams had better visibility into the changes being made in AD. Since sifting through event logs manually can be a challenge, investing in AD monitoring tools is the way forward. With proper auditing tools in place, you can detect anomalous user behavior through real-time alerts that signify malicious user activity. It is also important to audit privileged groups and modify them immediately in case inappropriate permissions were granted.
Insider threats are difficult to detect and prevent in time. Though AD groups are designed to grant permissions to many objects in one go, these permissions must be kept to a bare minimum. Regular employees donÍt require full control access to resources in the network. Administrators need to ensure that users only have access to the assets that they need to do their job and nothing more. Treating every employee as a potential insider threat through the Zero Trust model can reduce risks.
Unused groups pose as much damage as mismanaged group permissions. A security group with all its privileges intact can compromise your organizationÍs security if it falls into the wrong hands. Take inventory of your dormant or stale groups in the network and perform routine cleanup to keep your AD up to date.
AD groups are the doorway through which employees and devices are granted authentication; it is a good practice to perform periodic review of group permissions and settings through actionable reports.
Sometimes, default security groups have excessive permissions that may lead to users having more privileges than they need. Even if an employee requests access, it should be provided on a temporary basis as and when needed. The domain administrator account is generally only required for setting up the domain or during recovery in case of deletions. The account should not really be used for any other purpose and the credentials should not be shared and must be changed regularly.
ManageEngine ADManager Plus has capabilities for AD group management that simplify creating and managing of AD groups. You can add or remove multiple group members and configure attributes in bulk by simply importing a CSV file. The predefined, group-based reports give comprehensive information and can be exported in multiple formats.
