Interruption window: An interruption window, often referred to as a maintenance window, is a designated time frame set aside for system updates, backups, or other critical tasks that may disrupt normal operations. Planning these windows during off-peak hours minimizes the potential impact on users and business activities.

Intranet: A private network that uses internet technologies and protocols to provide access to information and resources within an organization. It is used by businesses and other organizations to share information and resources among employees or members. Examples of intranet use include internal company websites, databases, and file-sharing systems.

Intruder: An individual or entity that gains or attempts to gain unauthorized access to a system, network, or data. Intruders can originate from both outside and within an organization and may have various motives, including theft of information, disruption of services, or exploitation of resources for illicit activities. Identifying and responding to potential intruders is a critical part of maintaining security.

Intrusion: An act of unauthorized access or entry into a computer system or network. It is used in the context of cyber security to describe attempts by malicious actors to gain access to sensitive data or disrupt normal operations. Examples include hacking, malware, and phishing attacks.

Intrusion Detection System (IDS): A device or software application that monitors a network or system for malicious activities or policy violations. These systems work by collecting and analyzing information from various areas within a computer or a network to identify possible security breaches, which include both intrusions (attacks from outside the organization) and misuse (attacks from within the organization).

Intrusion Prevention System (IPS): A system that not only detects potential security breaches but also takes proactive countermeasures. These systems can automatically block or prevent detected malicious activities, helping to maintain the integrity and security of the network. Their methods can include denying network traffic, redirecting malicious activities, and providing reports of detected threats.
