In Microsoft’s Security, Compliance, and Identity portfolio, Microsoft Defender for Cloud Apps (formerly Microsoft Cloud App Security) integrates directly with Microsoft Entra Conditional Access to provide Conditional Access App Control—Microsoft’s real-time session control. Microsoft’s documentation describes this capability as enabling organizations to “monitor and control user sessions in real time” and to “protect downloads, restrict uploads, block copy/paste and print, and apply access or session policies” for sanctioned and unsanctioned applications. The enforcement is achieved through a reverse-proxy session that is invoked by Conditional Access policy decisions, allowing continuous inspection and dynamic controls after authentication.

By contrast, other options in the list do not offer real-time session enforcement via Conditional Access. Azure AD Privileged Identity Management (PIM) focuses on just-in-time role activation, approval workflows, and access reviews for privileged accounts—not session control of app usage. Microsoft Defender for Cloud provides cloud security posture management and workload protection across Azure, multicloud, and hybrid resources—again, not Conditional Access–based user session governance. Microsoft Sentinel is a SIEM/SOAR solution used for ingestion, detection, investigation, and response; it does not apply Conditional Access policies to control user sessions. Therefore, the service that can use Conditional Access policies to control sessions in real time is Microsoft Defender for Cloud Apps through Conditional Access App Control.

In the Microsoft 365 security center (now Microsoft 365 Defender), incidents are used to triage and investigate threats across the tenant. Microsoft’s security documentation explains that “an incident is a collection of related alerts” that are automatically correlated to give analysts a single, end-to-end view of an attack. Within each incident, the portal surfaces impacted assets such as devices, users, mailboxes, and applications, enabling responders to quickly identify which endpoints are affected by a given alert and to take response actions (isolate device, collect investigation package, run AV scan, etc.). This design allows security teams to move beyond individual alerts and instead work a consolidated investigation that lists affected devices in the incident’s Evidence & Response/Assets sections, complete with alert timelines and device details.

By comparison, Secure Score measures the organization’s security posture and recommendations; policies are configuration/enforcement objects (e.g., Defender or compliance policies) and are not the investigative view for alerts; classifications relate to information protection labeling rather than alert investigation. Therefore, to identify devices that are affected by an alert, you use the Incidents experience in Microsoft 365 Defender, where correlated alerts show the devices involved alongside the entities and evidence connected to the threat.

Microsoft states that Azure Bastion is a fully managed PaaS service that provides “secure and seamless RDP/SSH connectivity to your virtual machines directly in the Azure portal over SSL” and “eliminates the need to expose public IP addresses on your VMs.” With Bastion, users open the VM blade in the Azure portal and launch an in-browser RDP or SSH session; no separate RDP or SSH client is required because the session is proxied through Bastion using HTTPS/TLS. The platform is designed to be agentless and browser-based, providing connectivity without VPN or jump hosts and enforcing least-exposure by keeping management ports off the internet. While traditional tools such as Remote Desktop Connection or an SSH client are common for direct access, Bastion’s prescribed access method in Microsoft guidance is to initiate the session from the Azure portal. PowerShell remoting is unrelated to Bastion’s web-based brokering. Therefore, to connect to an Azure virtual machine by using Azure Bastion, you use the Azure portal.

In Microsoft 365, the unified audit log retention depends on the audit tier included with the subscription. Current SCI/Compliance documentation states that Audit (Standard)—which is available with Microsoft 365 E3—retains audit records for 180 days. The docs describe that organizations with E3 receive “up to 180 days of audit log retention” for user and admin activities captured in the unified audit pipeline. Longer retention (for example 365 days and beyond with customizable policies) is part of Audit (Premium) features generally associated with E5/E5 Compliance. Because the scenario specifies a Microsoft 365 E3 subscription using the unified audit log and Basic/Standard Audit, the retention period for audit records is 180 days.
