ZTNA (zero trust network access)
ZTNA (zero trust network access) is a way to give remote access to company applications by verifying identity, device and context on every connection, without opening up the whole network. Unlike a traditional VPN, users only see the applications they are allowed to use.

Principle of least privilege
The principle of least privilege states that every person, application or account should have only the permissions it needs to do its job, and nothing more. If an accounting account can only see financial data, an attacker who steals it cannot reach the servers or HR records.
Passkeys and security keys (FIDO2)
A passkey is a way to sign in without a password: your device stores a cryptographic key that you unlock with your fingerprint, face or a PIN. It is based on the FIDO2 standard, like physical security keys such as YubiKey, and it resists phishing because the key only works on the legitimate site.
Microsoft Entra ID (formerly Azure AD)
Microsoft Entra ID, formerly Azure Active Directory, is Microsoft's cloud identity service that controls who can sign in to Microsoft 365, Azure and thousands of applications. It lets you enforce MFA, conditional access and single sign-on, and it is the foundation of identity security in a Microsoft environment.
SAML, OAuth and OpenID Connect
SAML, OAuth and OpenID Connect are standards that let people sign in or grant permissions between applications without sharing passwords. SAML and OpenID Connect are used for single sign-on (SSO), and OAuth to authorize one application to access your data in another, like when you connect a calendar to your email.
Access control
Access control is the set of rules and tools that decide who can get into a system, which information they can see and what they are allowed to do. It combines identifying the person, verifying they are who they claim to be with methods such as MFA, and granting only the permissions their role requires, whether in an office or in an application.
