Importance of Identity Governance and Access Management
To ensure the security of your network, it is crucial to implement robust identity governance and access management practices, particularly when it comes to privileged accounts in your Active Directory (AD) environment. By effectively managing these accounts, you can prevent cyberattacks and safeguard your organization’s sensitive data.
Identity governance involves establishing policies and procedures for managing user identities and their access rights. This includes defining roles and responsibilities, enforcing strong password policies, and implementing multi-factor authentication. Access management, on the other hand, focuses on controlling and monitoring user access to resources based on their assigned privileges.
Privileged accounts, such as those belonging to administrators and system operators, have elevated privileges that grant them access to sensitive data and critical systems. These accounts are highly targeted by cybercriminals, who exploit them to gain unauthorized access and carry out malicious activities. Implementing strong identity governance and access management practices helps mitigate these risks.
Key Considerations for Identity Governance and Access Management
When establishing identity governance and access management practices for privileged accounts, there are several key considerations:
- Closely manage built-in privileged groups, such as Domain Admins and Local Administrators, on Windows endpoints. Regularly review membership, remove unnecessary users, and restrict access to minimize the risk of unauthorized access.
- Check for groups nested inside privileged groups. Attackers often exploit nested groups to gain broader access to critical resources and data. Ensure that only necessary groups have access to sensitive systems and information.
- Pay attention to organizational unit (OU) permissions and implement audit policies. Regularly monitor and review permissions to detect any unauthorized changes that could compromise the security of your network.
- Identify users with admin-equivalent rights on domain controllers (DCs) and uncover users with password reset authority over other accounts. This helps prevent potential privilege escalation attacks and ensures that only authorized users can make such critical changes.
- Monitor the use of privileged service accounts. These accounts should only be used for their assigned services and not for general user access. Regularly review and restrict the use of these accounts to minimize the risk of misuse.
By implementing these best practices, organizations can effectively manage privileged accounts, reduce the risk of unauthorized access and privilege escalation, and ensure the overall security of their network.
