An agent is a program installed on a physical server. An agent executes various server processes.

Agile Software Development

Agile is an iterative set of software development best practices. The top priorities in agile software development include software quality assurance, user feedback integration, and the ability to “fail fast” and implement rapid changes as needed.


An alert is used to notify an organization significant changes in their IT environment. Alerts can also indicate when a system has failed.

Alert Aggregation

Alert aggregation refers to the connection of all IT monitoring tools to view all alerts and incident data in one place.

Alert Fatigue

Alert fatigue occurs when many monitoring systems create an abundance of alerts that flood mailboxes. This causes alerts to become less meaningful, and often decreases the responsiveness of IT team members.

Alert Noise

Alert noise is a high volume of false alarms that makes it difficult to detect and respond to actual, important alerts.

Alert Rule

Alert rules are customized policies created by the user of an IT alerting system. They can be used to normalize the behavior of alerts based on time of day, type of alert and more.


Analytics are the application of statistics, research, and computing to gather insights and meaning from a set of data.


An API is used as an intermediary between different programs; an API ensures programs can share data with one another.

Application Release

Application release is a practice in which a software release is deployed across multiple environments and configurations with little to no human interaction.


An artifact is a descriptive model used to create software; artifact examples include diagrams and UML models. 

Assigned / Acknowledged Incident

An incident that has been assigned or acknowledged means that a specific team or individual has committed to taking accountability for and resolving the issue.


In IT alerting, automation is the technique of enabling the alerting process or notification system to operate automatically using alert rules. 


Autonomy in DevOps is self-governance. An autonomous DevOps team empowers each member to act based on the situation and resources available without the need to defer to a superior.

Capacity Test

A capacity test enables a DevOps team to determine the maximum number of end users an application, computer, or server can handle before it crashes. 


Categorization of incidents allows their impact, urgency, and severity to be easily understood and transparent.

Closed Incident

A closed incident is considered fully resolved, and it is confirmed that no additional action by a network operations center (NOC) or incident management team is necessary.


Closure is the confirmation that no further action needs to be taken on a resolved incident.

Communications Lead

In an incident response team, the communications lead facilitates communication about an incident to parties both inside and outside of the organization.

Complex-Adaptive System

BA complex-adaptive system consists of an IT platform or project that includes multiple components. In this system, each component interacts with others in ways that cannot be accurately predicted or controlled.

Configuration Drift

Configuration drift occurs when a hardware or software infrastructure configuration changes from a recovery or secondary configuration. It may occur due to inconsistent configurations across a set of computers or devices. 

Configuration Management

Configuration management is a system engineering process for creating and maintaining product consistency. It involves management of a product’s performance, function, and physical attributes relative to its design and requirements. 


Containerization is the use of virtual software containers that include operating system resources, memory, and services to run an application or service. It often helps a developer test production flows for services deployed in the cloud.


Containment is the third step in an incident response plan. The goal of this step is to quickly patch up the cause of the incident.

Continuous Delivery (CD)

Continuous delivery (CD) is a software engineering approach that utilizes short, frequent cycles to produce software.

Continuous Deployment

Continuous deployment utilizes automated software code testing. If code passes the automated test, the software automatically moves into a production environment.

Continuous Integration (CI)

Continuous integration (CI) is a software engineering practice that merges developer code changes into a single repository. Once CI is complete, the merged code is used to automate software builds and tests.

Continuous Quality

Continuous quality is the integration of software quality reviews into the CD pipeline. It requires quality assurance team members to review software code as soon as it becomes available, and address any potential code issues during the software development cycle.

Continuous Testing

Continuous testing is the execution of automated tests as part of the software delivery pipeline. It enables a DevOps team to get feedback for identifying potential risks before software is publicly released.

Cyber Threat

A cyber threat is any risk that may lead to a cyber-attack; cyber threats include malware and ransomware.


A cyber-attack is an attempt by hackers to penetrate a business’ IT networks or systems. 

Data Breach

DevSecOps (development and security operations) is a “security as code” culture that fosters collaboration between software developers and information security teams.


Diagnosis of an incident is a formulation of a hypothesis as to what caused the incident. An incident management team may be able to resolve an incident solely based on an initial diagnosis.

Documentation Lead

In an incident response team, the documentation lead documents the timeline of events during the incident response process.


Downtime is the period that a system is unable to perform its primary functions.


Eradication is the fourth step in an incident response plan. It aims to completely remove the threat causing an incident.


Incidents require escalation when more support is needed to resolve them. Teams gather and log incident information to prompt incident escalation to other team members or executives.


Escalation is bringing an issue to an individual or team in a higher department within an organization. For example, if a customer service representative finds an issue that can be resolved only by the IT team, the issue can be escalated to an IT manager.


An event is any occurrence that causes a change in the IT environment.

Event Management

Event management provides the ability to detect, interpret and act on the status of events in IT infrastructure and services. It aids in the automation of many service operations.

Event-Driven Architecture

Event-driven architecture is a form of software architecture that involves the creation of events by a system; the system then uses these events to identify or consume similar occurrences in the future.

Event-Triggered Alert

An event-triggered email is an automated alert sent via email, text, or phone call when a pre-determined event occurs.

Exploratory Testing

Exploratory testing is a strategy that provides human software testers with the ability to analyze different areas of a piece of software. It empowers human software testers with the flexibility to test potential software issues that may otherwise go undetected during automated tests.

HR/Legal Representative

Sometimes, incidents can cause an organization to be charged with a criminal offense. In an incident response team, the HR or legal representative must navigate any legal consequences of an incident.


Identification is the initial detection of an incident.

Identification / Detection and Analysis

Identification, also known as detection and analysis, is the second step in an incident response plan. In this step, research is done to find the cause of a detected incident.


Impact measures the effect of an incident on business processes. A high-impact incident may force business processes to come to a halt, whereas a low-impact incident has little or no effect on operations.

In-Progress Incident

An in-progress incident is one that is in the process of being mitigated.


An incident is an unplanned and undesired event that interrupts business operations. Incidents can cause downtime, revenue loss, compliance penalties, and brand reputation damage. Incidents can also affect employees and customers.

Overload occurs when a service demand exceeds its capacity. This can cause errors, and even network, server, or system overloads, causing an incident.

Pair Programming

Pair programming is a software development technique in which two developers simultaneously work on a single feature. It promotes collaboration, as both developers can analyze each other’s code to bolster overall code quality.


Organizations can use planning to shorten incident response and resolution times. Organizations plan for incident management by identifying potential events that may cause incidents before they happen.

Platform-as-a-Service (PaaS)

Platform as a service (PaaS) is a form of cloud computing service that involves the use of a platform to develop, run, and control applications. With PaaS, a third-party provider delivers hardware and software tools to end users via the internet.


Preparation is the first step in an incident response plan. In this step, all assets are complied, and ranked in order of importance.


Prioritization is the assessment of an incident and its impact on business processes and stakeholders. Different processes and workflows can be implemented depending on the priority level of an incident.

Problem Management

Problem management is a process for fixing system errors or weaknesses. Successful problem management limits the impact of incidents and ensures that an incident does not re-occur.

Resolution occurs after the necessary steps and processes to resolve an incident have been completed.

Resolved Incident

A resolved incident has been mitigated and all service has returned to SLA standards.

Retry Spike

If users are unable to access a service and repeatedly try to gain access, it causes a retry spike. Retry spikes can cause a service to shut down, causing an incident.

Rich Alerting

Rich alerting is the method of alerting in which all alerts are ensured to reach the correct and most relevant alert recipient, depending on the type of alert and the recipient’s schedule.

Role-Based Security

Role-based security ensures that users are restricted to viewing only data and alerts that are for them. For example, a software developer will not receive or be able to view alerts meant for a C-level employee.

Service-level Agreement (SLA)

A service-level agreement (SLA) is a commitment made between a service provider and its client. It can include elements such as reliability, responsiveness, obligations, and penalties to be implemented when the SLA is not followed.


Severity describes the impact of an incident on a business’ users. For a severe incident, a business may need to craft a public statement to its users. An incident of minor severity may require action but may not immediately affect users.


A stakeholder is any person with an interest and concern in a business. Stakeholders can include investors, users, employees, and executives of an organization.

Standard Operating Procedure (SOP)

A standard operating procedure (SOP) in IT alerting is a set of instructions compiled by an organization to help teams carry out routine IT operations based on alerts they receive.


In IT alerting, streamlining alerts makes organizations more efficient and effective by employing simpler working methods for received alerts.
