Resilience (in IT and Cybersecurity): The ability of an IT system or network to withstand and rapidly recover from incidents such as hardware failures, cyber-attacks, or natural disasters. It involves implementing strategies that enable the continuation of essential services and quick restoration to normal operations.

Resource Encapsulation (in IT): The practice of isolating resources and controlling access to them through strict interfaces or APIs. This helps ensure that only authorized processes or users can interact with sensitive data or system components, enhancing security and stability.

Resource (in IT and Cybersecurity): Any digital asset that supports information processes and services, such as hardware, software, information, network capacity, and user access. Effective management of these resources is essential to ensure they are used securely and efficiently to achieve business objectives.

Resource optimization: The process of maximizing the efficiency and effectiveness of resources to achieve desired results. It is used in operations management and project management to ensure that resources are used in the most effective and efficient manner. Examples include reducing waste and costs in production processes, minimizing downtime and disruptions in supply chain operations, and maximizing the use of available time and resources in project planning and execution.

Response in Disaster Recovery (DR): The actions taken to restore critical systems and services in the event of a disaster or major disruption. This is used in organizations to minimize the impact of disruptions on business operations and to ensure continuity of services. For example, a DR plan may include procedures for activating backup systems, communicating with stakeholders, and relocating to a recovery site.

Response in Incident Management: The actions taken to identify, assess, and manage security incidents. This is used in organizations to prevent or mitigate the impact of incidents and to restore normal operations as quickly as possible. For example, an incident response team may use tools and processes to contain an attack, collect evidence, and communicate with stakeholders.
