Terms in this definition

• MANAGE

  A Unity Catalog privilege allowing a principal to grant and revoke access on an object, hand over its ownership and drop it, all without being the owner. It gives no data access by itself and is not part of ALL PRIVILEGES.

• IaaS

  Infrastructure as a service: the customer runs and maintains virtual machines including their operating systems, for instance SQL Server hosted on an Azure VM.

• Virtual machines

  Infrastructure-as-a-service compute giving complete control of the operating system, making it a fit for lift-and-shift moves and for software relying on OS-level pieces like COM.

• PaaS

  Platform as a service, managed offerings such as Azure SQL Database and App Service in which the provider looks after the infrastructure and operating system.

• LIKE

  Compares strings with a pattern that can contain the % and _ wildcards. Because it only understands character patterns, searching big volumes of text this way is much slower than using full-text search.

• App Service

  Managed PaaS hosting for web apps and Web App for Containers, run in a sandbox without OS access. Deployment slots and autoscale start at the Standard tier.

  Infrastructure-as-a-service offering virtualised Linux or Windows servers with no hardware to buy. You pick size and operating system, though configuration, patching and upkeep remain your job.

• AzureDiagnostics

  Log Analytics table shared by many services, receiving Azure resource logs from diagnostic settings that use the legacy Azure diagnostics mode, Azure Firewall logs being one example. Guest operating system logs don't go here.

  You can sort Defender for Endpoint machines into groups using rules that match their name, domain, tag or operating system. Each group gets its own level of automated remediation, and access to its devices can be limited to chosen Entra user groups.

• DeviceInfo

  Holds details about each machine in advanced hunting, its operating system among them.

• DHCP

  Azure delivers each NIC's private IP to the guest operating system using this protocol, so keep the OS set to obtain addresses automatically and configure any static IP on the Azure NIC.

• Event Viewer

  Console built into Windows for reading what the operating system and applications have recorded, with saved filtered views and support for collecting events from other machines.

• File integrity monitoring

  Capability in Defender for Servers Plan 2 that watches registry keys, configuration files and operating system files on Linux and Windows machines for changes.

• Guest data

  Telemetry captured within a virtual machine's operating system: Windows events, Syslog, perf counters, IIS logs and text logs. Azure Monitor Agent has to be installed, with a data collection rule, before any of it is gathered.
