Evidence or artifacts found on a network or operating system that indicate a high probability of a security breach.

Inference

The stage where a trained AI model is used to make predictions or generate outputs based on new, unseen input data.

Inferential Statistics

The process of using data analysis to deduce properties of an underlying probability distribution.

The practice of protecting information by mitigating information risks, ensuring confidentiality, integrity, and availability.

Infrastructure as a Service(IaaS)

A cloud model that provides on-demand access to fundamental computing resources like servers and storage.

Infrastructure as Code(IaC)

The management and provisioning of infrastructure through machine-readable definition files, rather than manual configuration or interactive tools.

Infrastructure as Code (IaC) Scanning

The process of analyzing infrastructure definition files (e.g., Terraform, CloudFormation) for security misconfigurations before they are deployed.

Infrastructure as Code (Networking)(IaC)

Managing and provisioning network infrastructure through machine-readable definition files rather than manual configuration.

Infrastructure Monitoring

The process of collecting and analyzing metrics and logs from cloud resources to ensure their health, performance, and availability.

Ingress

An API object that manages external access to services in a Kubernetes cluster, typically HTTP.

Initial Coin Offering(ICO)

A fundraising method where a new project sells its native tokens to early investors.

Initial DEX Offering(IDO)

A token launch conducted on a decentralized exchange (DEX).

Initial Exchange Offering(IEO)

A token sale managed by a centralized exchange (CEX) on behalf of a project.

In-Memory Cache

A high-speed data storage layer that stores a subset of data in RAM to serve future requests faster than accessing the primary database.

Input/Output(I/O)

The communication between an information processing system (such as a computer) and the outside world.

A level of software testing where individual units are combined and tested as a group.

Interaction to Next Paint(INP)

A Core Web Vital that measures a page's overall responsiveness to user interactions throughout its entire lifecycle.

Interrupt

A signal to the processor emitted by hardware or software indicating an event that needs immediate attention.

Interrupt Request(IRQ)

A signal sent to the CPU to temporarily stop a running program and allow a special piece of code (an ISR) to run instead.

Interrupt Service Routine(ISR)

A software routine that hardware invokes in response to an interrupt.

Intranet

A private network accessible only to an organization's staff, used for internal communication and collaboration.

Intrusion Detection System(IDS)

A device or software that monitors a network or systems for malicious activity.
