5

  • 5250 Emulation

    Software running on a modern PC that displays and interacts with IBM i's traditional text-based screens, the interface most people mean by "green screen."

A

  • Agentic SOC

    A security operations model in which AI agents use approved tools and context to perform bounded investigation, reporting, and response work under defined human governance.

  • AI-Based SIEM

    A vendor label for a SIEM that uses AI in a core function such as detection, correlation, prioritization, or investigation.

  • AI-Driven SIEM

    A SIEM in which AI guides a broader share of the security workflow, often from prioritization and investigation through recommended or approved response.

  • AI Governance

    The policies and technical controls that define which AI systems may use which data, perform which actions, and produce which evidence under human oversight.

  • AI-Native SIEM

    A SIEM designed to use AI across security data, detection, investigation, and response rather than limiting AI to a separate assistant feature.

  • AI-Powered SIEM

    A SIEM that uses machine learning, generative AI, or both for one or more tasks such as detection, triage, investigation, or response.

  • AS400

    The original IBM midrange business computer line, introduced in 1988, whose operating system evolved into today's IBM i running on IBM Power Systems.

C

  • Capacity on Demand (CoD)

    A licensing option on IBM Power Systems hardware that lets a customer activate additional processor or memory capacity already installed in the machine, as needed, without a physical hardware change.

D

  • DB2 for i

    The relational database built directly into the IBM i operating system, rather than installed as a separate product.

E

  • Extended Detection and Response (XDR)

    A security approach that combines detection and response across several telemetry domains such as endpoint, identity, cloud, email, and network.

  • End of Support (EOS)

    The date after which IBM stops issuing security patches, fixes, and official support for a given hardware generation or IBM i release.

F

  • FIELDPROC

    A DB2 for i feature that automatically encrypts and decrypts specific database columns, added transparently without changing existing application code.

H

  • Headless SIEM

    A SIEM that exposes approved, permission-aware security capabilities through AI agents, APIs, automations, dashboards, and service workflows as well as its normal interface.

I

  • IBM i

    The operating system descended from the original AS400's OS/400, now running on current IBM Power Systems hardware, with an integrated relational database (DB2 for i) built into the OS itself.

  • IBM Power Systems

    IBM's current server hardware line built on the Power processor architecture, the direct successor to System i/iSeries hardware and the platform current IBM i systems run on.

  • IBM Storwize

    IBM's discontinued mid-range and entry-level virtualized SAN storage brand (V7000, V3700, and others), replaced by IBM FlashSystem in 2020.

L

  • LPAR (Logical Partition)

    A logically divided, independently running slice of a single physical IBM Power Systems server, each with its own operating system, memory, and processor allocation.

  • LTO (Linear Tape-Open)

    The open tape cartridge standard used by IBM's tape libraries and autoloaders, currently on its 10th generation (LTO-10, 40 TB native per cartridge).

M

  • Managed Detection and Response (MDR)

    A security service in which an outside team monitors detections, investigates activity, and performs or coordinates agreed response work for the customer.

  • Managed SIEM

    A SIEM offered as an ongoing service by a third-party provider, rather than software an organization installs, tunes, and staffs itself.

P

  • Power 11

    The current generation of IBM Power Systems hardware, the newest platform a legacy AS400/IBM i workload can be migrated onto.

  • PowerVM

    IBM's built-in virtualization layer for Power Systems hardware, the hypervisor that creates and manages LPARs.

R

  • RPG

    A programming language, originally built for business reporting, that is still the dominant application language on IBM i systems today.

S

  • Security Data Ingestion

    The process of receiving security events and telemetry from endpoints, identities, networks, cloud services, applications, and other sources into a SIEM or data platform.

  • Security Data Pipeline

    The controlled flow that collects, parses, normalizes, enriches, filters, and routes security telemetry before a SIEM stores or analyzes it.

  • Security Data Quality

    The completeness, accuracy, timeliness, consistency, and context of the telemetry a SIEM uses for detection and investigation.

  • SIEM Data Retention

    The period and storage tier in which security events remain available for search, investigation, threat hunting, audit, or recovery.

  • Security Orchestration, Automation, and Response (SOAR)

    Technology that coordinates security workflows across tools and automates defined investigation or response steps.

  • SIEM

    A security system that collects log and event data from across an organization's systems and analyzes it centrally to detect and alert on threats.

T

  • Tape Autoloader

    A compact, single-drive tape unit that automatically loads cartridges from a small internal magazine in sequence, without the multi-drive capacity or cost of a full tape library.

  • Technology Refresh (TR)

    IBM's periodic incremental update to a given IBM i release, delivering new features and fixes without requiring a full operating system upgrade.

U

V

  • Virtual Tape Library (VTL)

    A disk-based backup appliance that presents itself to backup software exactly like a physical tape library or drive, so existing tape-based save jobs and scripts keep working unchanged.
