32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Confidentiality, Integrity, Availability
The CIA triad: confidentiality keeps data readable only by authorized parties, integrity keeps data accurate and unaltered, and availability keeps systems accessible to legitimate users when needed.
Defense in depth
A layered security strategy placing controls at physical, identity, network, compute, application, and data levels so a single failed control does not expose the whole asset.
Zero Trust model
A security approach that verifies every request explicitly, grants least privilege, and assumes breach, so no user or device is trusted based solely on network location.
Shared responsibility model
A division of security duties: the cloud provider secures physical hosts and infrastructure, while the customer remains responsible for data, identities, access, and configuration.
Authentication vs authorization
Authentication verifies who a principal is, such as by password or token; authorization determines which resources and actions that authenticated principal is permitted to use.
Encryption vs hashing
Encryption is reversible with a key and protects data at rest or in transit; hashing is one-way, used for integrity checks and password storage, and cannot be reversed.
Compliance vs governance
Compliance means meeting external laws, regulations, and standards; governance is the internal policies, roles, and controls that keep the organization aligned with those obligations.
Microsoft Entra ID
Microsoft's cloud identity provider that authenticates users and applications and issues tokens for access to Microsoft 365, Azure, and integrated applications.
Conditional Access
An Entra ID policy engine that evaluates sign-in signals such as user, device, location, and risk, then grants, requires controls like MFA, or blocks access.
Entra roles vs Azure RBAC
Entra ID roles manage directory objects such as users and groups; Azure role-based access control manages actions on Azure resources at scopes like subscription or resource group.
Multi-factor authentication
Authentication requiring factors from at least two distinct categories, such as a password plus an authenticator app code, so a stolen password alone is insufficient.
Self-service password reset
An Entra ID feature letting users reset or unlock their own accounts after verifying identity with configured methods, reducing helpdesk load and lockout delays.
Privileged Identity Management
An Entra ID service providing just-in-time activation, approval workflows, and access reviews for privileged roles, replacing permanent standing administrative access.
Identity Protection
An Entra ID service that detects risky sign-ins and users, assigns risk levels, and can drive Conditional Access policies that require remediation or block access.
Hybrid identity
A configuration connecting on-premises Active Directory to Entra ID through synchronization or federation, so users use one credential across both environments.
External identities
Entra ID features for partners and customers, including B2B collaboration for guest access and External ID for customer-facing applications, without internal account creation.
Microsoft Defender for Cloud
A cloud security service combining posture management with Secure Score recommendations and workload protection for servers, storage, containers, and databases.
Microsoft Sentinel
A cloud-native SIEM and SOAR platform that ingests logs, detects threats with analytics rules, and automates response using playbooks built on Logic Apps.
Defender XDR
Microsoft's extended detection and response service that correlates signals from identities, endpoints, email, and cloud apps into unified incidents for faster investigation.
Defender for Endpoint
An endpoint security service providing threat detection, attack surface reduction, and automated investigation and response for managed devices such as laptops and servers.
Defender for Office 365
An email and collaboration protection service using Safe Links, Safe Attachments, anti-phishing, and anti-spam policies to block malicious content in Microsoft 365.
Defender for Cloud Apps
A cloud access security broker that discovers shadow IT, governs sanctioned apps, and applies session and app-control policies to cloud application usage.
Secure Score
A Defender for Cloud metric scoring an environment against recommended security controls, where implementing more recommendations raises the score and improves posture.
Defender for Identity
A security service monitoring on-premises Active Directory signals to detect identity-based attacks such as credential theft, reconnaissance, and lateral movement.
Microsoft Purview
A compliance family covering data classification, sensitivity and retention labels, data loss prevention, eDiscovery, audit, and insider risk management across Microsoft 365.
Sensitivity labels
Purview labels that classify content and can apply encryption and content marking; the protection travels with the file even when shared outside the organization.
Retention labels and policies
Purview controls that keep, delete, or retain-then-delete content for defined periods; event-based labels can start retention from a trigger such as a contract end date.
Data Loss Prevention
Purview policies that detect sensitive information types and warn, block, or restrict sharing across email, SharePoint, OneDrive, Teams, and endpoint devices.
eDiscovery
A Purview capability to search, preserve, and export content for legal cases; Premium adds custodian management, review sets, and analytics beyond standard search.
Compliance Manager
A Purview tool that maps controls to regulations, tracks improvement actions, and calculates a compliance score reflecting progress toward assessment requirements.
Microsoft Priva
A privacy management product supporting subject rights requests, privacy risk assessment, and consent or tracking controls for personal data across the organization.
Purview Audit
A logging capability recording user and administrator activity; Standard provides default retention, while Premium adds longer retention and higher-fidelity events for investigations.
