Term 692
Qualitative risk analysis is a subjective, scenario-based approach to prioritizing information security risks by evaluating their likelihood and potential impact using predefined scales rather than numerical calculations.
Term 693
Quantitative risk analysis is a structured process that uses numerical data and statistical methods to calculate the potential financial impact of risks on an organization's assets and projects.
Term 694
Quarantine is a security process that isolates a potentially malicious file, email, or device from the rest of the system to prevent harm while it is analyzed or remediated.
Term 695
Radio Frequency Identification (RFID) is a wireless technology that uses radio waves to automatically identify and track tags attached to objects, people, or animals without requiring direct line-of-sight.
Term 696
RADIUS is a network protocol that provides centralized authentication, authorization, and accounting management for users who connect and use a network service.
Term 697
Ransomware is a type of malicious software that encrypts a victim's files or locks them out of their system, demanding payment, usually in cryptocurrency, to restore access.
Term 698
A Rapid Security Response is an emergency software patch from Apple that fixes critical security flaws in iOS, iPadOS, macOS, and other Apple operating systems without requiring a full system update.
Term 699
RBAC is a method of restricting network access based on the roles of individual users within an organization, where permissions are assigned to roles rather than to individuals directly.
Term 700
A read replica is a copy of a database that is used only to handle read queries, taking load off the primary database.
Term 701
Read-access geo-redundant storage (RA-GRS) is a cloud storage replication option that maintains three synchronous copies in one primary region and three asynchronous copies in a secondary region, while allowing read access to the secondary copy even during normal operations.
Term 702
Recovery is the process of restoring systems, data, and operations after a security incident, failure, or disaster to return to normal functioning.
Term 703
A recovery key is a unique code or physical device used to regain access to an encrypted system or account when the primary authentication method, such as a password or biometric, is lost or unavailable.
Term 704
A red team is a group of security professionals who simulate real-world attacks on an organization's systems, people, and facilities to test the effectiveness of its defenses.
Term 705
Redis is an open-source, in-memory data structure store used as a database, cache, and message broker for high-speed data access.
Term 706
Redundancy is the practice of adding extra components or systems so that if one fails, another can take over without interruption.
Term 707
A trusted, always-active component of a computer's operating system that enforces security policies by checking every access request to files, memory, or devices before allowing it.
Term 708
A region is a distinct geographic location where a cloud provider operates multiple data centers that are connected by low-latency networks and provide cloud services.
Term 709
A region pair is two Azure regions within the same geography that are at least 300 miles apart and are used together to provide data residency, compliance, and high availability through paired recovery and updates.
Term 710
Regional refers to a deployment strategy where cloud resources are distributed across multiple geographic areas to improve availability, reduce latency, and meet compliance requirements.
Term 711
Regional Persistent Disk is a durable, block-level storage option in Google Cloud that automatically replicates data across two zones in a region to protect against zone failures.
Term 712
Regression is a type of machine learning algorithm that predicts a continuous numeric output based on input data, used to model relationships between variables.
Term 713
A regulatory requirement is a rule issued by a government or industry authority that organizations must follow, often to protect data, ensure safety, or maintain fair practices.
Term 714
Reinforcement learning is a machine learning approach where an agent learns to make decisions by taking actions in an environment to maximize cumulative reward.
Term 715
A relational database organizes data into tables with rows and columns, where each table relates to others using unique keys, allowing efficient storage, retrieval, and manipulation of structured information.
Term 716
Reliability is the measure of a system's ability to consistently perform its intended functions without failure over a specified period of time under stated conditions.
Term 717
Reliability and safety in IT means that systems consistently perform their intended functions without failure and that they operate without causing harm to people, data, or the environment.
Term 718
The Reliability pillar is a set of best practices in cloud architecture that ensures a system can recover from failures, scale to meet demand, and deliver consistent performance over time.
Term 719
A remediation script is an automated set of instructions that detects and fixes common IT security or configuration issues without manual intervention.
Term 720
