MIM Privileged Access Management (PAM) is a solution that helps organizations restrict privileged access within an existing and isolated Active Directory environment.
Privileged Access Management accomplishes two goals:
•Re-establish control over a compromised Active Directory environment by maintaining a separate bastion environment that is known to be unaffected by malicious attacks.
•Isolate the use of privileged accounts to reduce the risk of those credentials being stolen.
Today, it's too easy for attackers to obtain Domain Admins account credentials, and it's too hard to discover these attacks after the fact. The goal of PAM is to reduce opportunities for malicious users to get access, while increasing your control and awareness of the environment.
PAM makes it harder for attackers to penetrate a network and obtain privileged account access. PAM adds protection to privileged groups that control access across a range of domain-joined computers and applications on those computers. It also adds more monitoring, more visibility, and more fine-grained controls. This allows organizations to see who their privileged administrators are and what are they doing. PAM gives organizations more insight into how administrative accounts are used in the environment.
PAM builds on the principle of just-in-time administration, which relates to just enough administration (JEA). JEA is a Windows PowerShell toolkit that defines a set of commands for performing privileged activities. It is an endpoint where administrators can get authorization to run commands. In JEA, an administrator decides that users with a certain privilege can perform a certain task. Every time an eligible user needs to perform that task, they enable that permission. The permissions expire after a specified time period, so that a malicious user can't steal the access.
PAM setup and operation has four steps.
1.Prepare: Identify which groups in your existing forest have significant privileges. Recreate these groups without members in the bastion forest.
2.Protect: Set up lifecycle and authentication protection for when users request just-in-time administration.
3.Operate: After authentication requirements are met and a request is approved, a user account gets added temporarily to a privileged group in the bastion forest. For a pre-set amount of time, the administrator has all privileges and access permissions that are assigned to that group. After that time, the account is removed from the group.
4.Monitor: PAM adds auditing, alerts, and reports of privileged access requests. You can review the history of privileged access, and see who performed an activity. You can decide whether the activity is valid or not and easily identify unauthorized activity, such as an attempt to add a user directly to a privileged group in the original forest. This step is important not only to identify malicious software but also for tracking "inside" attackers.
PAM is based on new capabilities in AD DS, particularly for domain account authentication and authorization, and new capabilities in Microsoft Identity Manager. PAM separates privileged accounts from an existing Active Directory environment. When a privileged account needs to be used, it first needs to be requested, and then approved. After approval, the privileged account is given permission via a foreign principal group in a new bastion forest rather than in the current forest of the user or application. The use of a bastion forest gives the organization greater control, such as when a user can be a member of a privileged group, and how the user needs to authenticate.
Active Directory, the MIM Service, and other portions of this solution can also be deployed in a high availability configuration.
The following example shows how PIM works in more detail.
The bastion forest issues time-limited group memberships, which in turn produce time-limited ticket-granting tickets (TGTs). Kerberos-based applications or services can honor and enforce these TGTs, if the apps and services exist in forests that trust the bastion forest.
Day-to-day user accounts do not need to move to a new forest. The same is true with the computers, applications, and their groups. They stay where they are today in an existing forest. Consider the example of an organization that is concerned with these cybersecurity issues today, but has no immediate plans to upgrade the server infrastructure to the next version of Windows Server. That organization can still take advantage of this combined solution by using MIM and a new bastion forest, and can better control access to existing resources.
PAM offers the following advantages:
There are a number of ways in which a user can submit a request, including:
•The MIM Services Web Services API
•A REST endpoint
•Windows PowerShell (New-PAMRequest)
As an example, let's say a user was a member of an administrative group before PAM is set up. As part of PAM setup, the user is removed from the administrative group, and a policy is created in MIM. The policy specifies that if that user requests administrative privileges, the request is approved and a separate account for the user will be added to the privileged group in the bastion forest.
Assuming the request is approved, the Action workflow communicates directly with bastion forest Active Directory to put a user in a group. For example, when Jen requests to administer the HR database, the administrative account for Jen is added to the privileged group in the bastion forest within seconds. Her administrative account's membership in that group will expire after a time limit. With Windows Server 2016 or later, that membership is associated in Active Directory with a time limit.
