Azure Active Directory (Azure AD) Privileged Identity Management (PIM) is a service that enables you to manage, control, and monitor access to important resources in your organization. When a privileged account needs to be used, it first needs to be requested, and then approved. 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. For more information about replication latency, see In contrast, an expired link is evaluated in real time by the Security Accounts Manager (SAM). 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.There are a number of ways in which a user can submit a request, including:As an example, let’s say a user was a member of an administrative group before PIM is set up. Particularly troubling are: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.
As part of PIM setup, the user is removed from the administrative group, and a policy is created in MIM. Privileged access management (PAM) helps in maintaining the security of your network. Some of the benefits include passwords management, workflow, session management… This is done through Just-In-Time (JIT) administration instead of distributed access. Privileged Access Management remplit deux objectifs : Privileged Access Management accomplishes two goals: Rétablissement du contrôle d’un environnement Active Directory compromis en conservant un environnement …

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. Privileged Access Management (PAM) is a solution that helps organizations restrict privileged access within an existing Active Directory environment.

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). Ainsi, un utilisateur malveillant ne peut pas dérober l’accès.The permissions expire after a specified time period, so that a malicious user can't steal the access.La configuration et l’utilisation de PAM comportent quatre étapes.Recréez ces groupes sans membres dans la forêt bastion.Recreate these groups without members in the bastion forest.L'authentification multifacteur permet de prévenir les attaques par programmation à partir de logiciels malveillants ou suite à un vol d'informations d'identification.MFA helps prevent programmatic attacks from malicious software or following credential theft.Pendant un laps de temps prédéfini, l’administrateur dispose de tous les privilèges et autorisations d’accès qui sont affectés à ce groupe.For a pre-set amount of time, the administrator has all privileges and access permissions that are assigned to that group.Au bout de ce laps de temps, le compte est supprimé du groupe.After that time, the account is removed from the group.Vous pouvez consulter l’historique de l’accès privilégié et voir qui a effectué une activité.You can review the history of privileged access, and see who performed an activity.Vous pouvez décider si l’activité est valide ou non et identifier facilement toute activité non autorisée, par exemple une tentative d’ajout d’un utilisateur directement à un groupe privilégié dans la forêt d’origine.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.Cette étape est importante non seulement pour identifier les logiciels malveillants, mais également pour suivre les pirates « infiltrés ».This step is important not only to identify malicious software but also for tracking "inside" attackers.PAM est basé sur les nouvelles fonctionnalités des services AD DS, en particulier pour l’authentification et l’autorisation des comptes de domaine, ainsi que sur les nouvelles fonctionnalités de Microsoft Identity Manager.PAM is based on new capabilities in AD DS, particularly for domain account authentication and authorization, and new capabilities in Microsoft Identity Manager.PAM sépare les comptes privilégiés d’un environnement Active Directory existant.PAM separates privileged accounts from an existing Active Directory environment.Quand un compte privilégié doit être utilisé, il doit tout d'abord être demandé, puis approuvé.When a privileged account needs to be used, it first needs to be requested, and then approved.Après l'approbation, l'autorisation est accordée au compte privilégié via un groupe principal étranger dans une nouvelle forêt bastion plutôt que dans la forêt actuelle de l'utilisateur ou de l'application.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.L'utilisation d'une forêt bastion offre à l'organisation un meilleur contrôle.
