 Azure DDoS Protection Standard protects against man-in-the-middle (MITM) attacks. = No

 Azure DDoS Protection Standard is enabled by default in an Azure subscription. = No

 Azure DDoS Protection Standard protects against protocol attacks. = Yes

Microsoft’s security guidance for Azure states that DDoS Protection is designed to defend internet-facing resources from distributed denial-of-service events at the network and transport layers (L3/L4). The documentation explains that DDoS Protection Standard provides “adaptive, real-time tuning and automatic attack mitigation for volumetric and protocol attacks (for example, SYN/ACK floods, UDP amplification, and other L3/L4 patterns).” It further clarifies that DDoS Protection is not intended to address attacks like man-in-the-middle (MITM), which are interception/alteration threats rather than traffic-exhaustion scenarios.

Regarding enablement, Microsoft notes that Azure DDoS Protection Standard is not enabled by default. The platform provides “basic DDoS protection for all Azure public IP addresses,” but the Standard plan must be explicitly enabled on a virtual network and then applied to public IP resources in that VNet to gain its enhanced telemetry, mitigation policies, and cost-protection benefits.

Putting this together: (1) MITM is out of scope for DDoS Protection Standard → No; (2) Standard is opt-in, not automatic → No; (3) Protection against protocol attacks is a primary capability of the Standard plan → Yes.

Within Microsoft Purview, Insider Risk Management is the solution that is explicitly designed to detect activities such as IP theft and data leakage. Microsoft describes it as a compliance solution that correlates many user and system signals to identify potentially malicious or inadvertent insider risks, including leaks of sensitive data and data spillage.

Organizations create Insider Risk Management policies that watch for risky behaviors such as unusual file downloads, copying data to removable media, or sharing sensitive information to external locations. When configured with templates like Data leaks, these policies can use high-severity alerts from Data Loss Prevention (DLP) policies as triggers, so that suspected data-leak events automatically generate alerts and cases for investigation. This workflow lets investigators quickly triage, investigate, and remediate possible data-exfiltration incidents.

The other options serve different purposes. Compliance Manager evaluates and tracks compliance posture against regulations and internal controls, rather than monitoring user behavior for leaks. Communication compliance focuses on inappropriate or non-compliant messages (such as harassment or improper sharing in chats and email). eDiscovery is used to find and preserve existing content for legal or investigative cases, not for proactive detection of leakage as it occurs.

Therefore, the Microsoft Purview solution used to identify data leakage is Insider Risk Management.

Azure Firewall is a managed, cloud-based network security service designed to secure traffic inside and across Azure Virtual Networks. Microsoft describes Azure Firewall as a stateful firewall that “protects Azure Virtual Network resources” by enforcing network and application rules, central logging, and threat intelligence–based filtering. Because it is deployed into a VNet/subnet (often as the hub in a hub-and-spoke), it directly governs East/West and North/South flows to workloads such as Azure virtual machines and platform services reachable through the VNet, using DNAT/SNAT and rule collections. Microsoft guidance highlights capabilities to “centrally create, enforce, and log application and network connectivity policies across subscriptions and virtual networks,” and to filter traffic for peered VNets, branch connections (VPN/ExpressRoute), and internet traffic. These capabilities explicitly map to protecting Azure virtual networks and the VMs and subnets inside them. In contrast, Azure AD users, Exchange Online inboxes, and SharePoint Online sites are SaaS/identity resources protected by Microsoft Entra controls, Exchange/SharePoint security, and Purview/Defender for Office 365—not by a VNet firewall. Therefore, the Azure Firewall–protectable resource types among the options are Azure virtual machines and Azure virtual networks.
