Zero Trust

A security model that grants no implicit trust based on network location and instead verifies every user, device, and request before allowing access to a resource.

Related: Least Privilege, Microsegmentation
Microsegmentation

Dividing a network or workload environment into small isolated zones with individual access policies, so a compromise in one zone cannot freely reach the others.

Next-Generation Firewall (NGFW)

A firewall that inspects traffic beyond ports and addresses, identifying applications and users and applying intrusion prevention and threat signatures inline.

Related: App-ID, Security Zone
App-ID

A classification technology that identifies an application by its traffic behavior and signatures rather than by port number, so apps evading standard ports are still recognized.

User-ID

A capability that maps network traffic to the specific authenticated user or group behind it, enabling policies and logs to be written in terms of people, not just IP addresses.

Related: Security Policy Rule, Identity Provider (IdP)
Security Zone

A logical grouping of interfaces or subnets that share the same trust level, such as internal, DMZ, or internet, and to which policy rules are applied.

Related: Microsegmentation, Security Policy Rule
Security Policy Rule

An ordered statement that matches traffic by source, destination, application, and user, then specifies whether to allow, deny, or inspect it further.

Related: App-ID, Security Zone
SSL/TLS Decryption

The process of terminating encrypted sessions at a security device, inspecting the plaintext for threats, then re-encrypting before forwarding, subject to legal and privacy exceptions.

Related: Next-Generation Firewall (NGFW), Data Loss Prevention (DLP)

Observable evidence that a system may already be breached, such as unusual outbound connections, known malicious file hashes, or unexpected registry changes.

Related: Threat Intelligence Feed, Security Information and Event Management (SIEM)
Security Information and Event Management (SIEM)

A platform that collects logs and events from many sources, correlates them, and raises alerts, giving analysts a centralized view for investigation and compliance reporting.

Related: Indicator of Compromise (IoC), SOAR
SOAR

Security orchestration, automation, and response: tooling that runs predefined playbooks to enrich alerts and execute repetitive response steps with less manual effort.

Related: Security Information and Event Management (SIEM), Playbook
Playbook

A documented, often automated sequence of steps an analyst or platform follows for a specific scenario, such as phishing triage or host isolation.

Related: SOAR, Incident Response Lifecycle
Incident Response Lifecycle

The staged process of preparing, detecting and analyzing, containing, eradicating, recovering from, and learning from a security incident.

Related: Playbook, Mean Time to Detect (MTTD)
Mean Time to Detect (MTTD)

The average elapsed time between the start of a real security incident and its discovery by monitoring or staff, a common measure of detection effectiveness.

SASE

Secure Access Service Edge: a cloud-delivered architecture that combines network connectivity services with security controls, delivered close to users regardless of location.

Related: SSE, SD-WAN
SSE

Security Service Edge: the security-focused subset of SASE, typically covering secure web gateway, cloud access security broker, firewall as a service, and zero trust network access.

Related: SASE, Secure Web Gateway (SWG)
SD-WAN

Software-defined wide area networking that steers branch traffic across multiple links based on application policy, often paired with cloud security in a SASE design.

Related: SASE, Branch Office
Secure Web Gateway (SWG)

A proxy-based control that inspects and filters user web traffic, blocking malicious sites, enforcing acceptable use, and applying decryption and file controls.

Related: SSE, SSL/TLS Decryption
Cloud Access Security Broker (CASB)

A control point that sits between users and cloud services to enforce policy, discover unsanctioned apps, and protect data moving to or stored in SaaS.

Related: Shadow IT, Data Loss Prevention (DLP)
Shadow IT

Cloud applications and services used by employees without IT approval, creating unmanaged data exposure that discovery tools are meant to surface and address.

Related: Cloud Access Security Broker (CASB), SaaS Security Posture Management (SSPM)
Zero Trust Network Access (ZTNA)

A service that gives users access to specific internal applications after identity and device checks, without placing them on the broader corporate network.

Related: Zero Trust, Identity Provider (IdP)
Branch Office

A remote business site that typically needs local connectivity and security but may lack on-site IT staff, making cloud-delivered controls attractive.

Related: SD-WAN, SASE
Shared Responsibility Model

The division of security duties between a cloud provider and its customer, where the provider secures the cloud itself and the customer secures what they put in it.

Related: Cloud Workload Protection, Misconfiguration
Cloud Workload Protection

Controls that monitor and defend compute instances, containers, and serverless functions in cloud environments against malware, exploitation, and unauthorized behavior.

Related: Shared Responsibility Model, Container Security
Cloud Security Posture Management (CSPM)

Continuous assessment of cloud configurations against benchmarks to find risky settings, such as public storage buckets or overly permissive roles, before attackers exploit them.

Related: Misconfiguration, SaaS Security Posture Management (SSPM)
