Domain 4: Security Operations, Monitoring, and Incident Response

Covers monitoring, detection, resilience, and response in cloud environments. This domain emphasizes logging and visibility, threat detection and investigation, incident response, forensics, backup and disaster recovery, and continuous security improvement.

Key Terms to Know

These terms are loaded from the shared terminology pack and appear across the question explanations.

API security

The discipline of protecting application programming interfaces from abuse, unauthorized access, and data exposure.

Cloud Incident Response Plan

A documented set of roles, responsibilities, and procedures for detecting, responding to, and recovering from cloud security incidents.

Cloud bursting

The use of public cloud resources to handle excess workload demand when private capacity is insufficient.

Comprehensive logging

The collection of detailed records of activities across systems, users, APIs, and networks for monitoring and investigation.

Confidential/Restricted data

A high-sensitivity data classification for information that could cause serious harm if disclosed.

Configuration baseline

An approved standard configuration used as the reference point for secure system settings.

Container escape

An attack in which a process inside a container breaks isolation and gains access to the host or other containers.

Container security

The practices and controls used to protect containerized applications and their runtime environments.

Continuous monitoring

Ongoing observation of systems and controls to detect changes, anomalies, or security issues in near real time.

Data Encryption Key (DEK)

A cryptographic key used directly to encrypt and decrypt data.

Data classification

The process of labeling data based on sensitivity, value, and handling requirements.

Data lifecycle management

The governance of data from creation through use, storage, retention, archival, and disposal.

Deterministic encryption

An encryption method that produces the same ciphertext for the same plaintext, enabling exact-match searches.

Elastic scalability

The ability to rapidly increase or decrease computing resources in response to workload changes.

Encryption in transit

Protection of data while it moves across networks, typically using secure transport protocols.

Exact-match search

A query operation that looks for identical values, often supported on deterministically encrypted fields.

Hierarchical key management

A key structure in which higher-level keys protect lower-level keys to support separation and scalability.

Hybrid cloud

A deployment model that combines private cloud or on-premises resources with public cloud services.
