The most effective way to protect network traffic from interception is Transport Layer Security (TLS). TLS provides confidentiality, integrity, and authentication by encrypting data as it travels between client and server. Unlike older protocols like SSL, which is now deprecated due to vulnerabilities, TLS is the industry-standard protocol endorsed by modern security frameworks.

Compression and password protection through GZ is not a reliable method, as it does not offer strong encryption or resistance against sophisticated interception attacks. GRE is a tunneling protocol and does not inherently provide encryption.

By implementing TLS, organizations ensure protection against on-path attacks, replay attacks, and packet sniffing. TLS also supports features such as forward secrecy and certificate-based authentication, ensuring both secure data transmission and mutual trust between endpoints. In compliance-driven industries like healthcare and finance, TLS is explicitly mandated for protecting sensitive information in transit.

During the preparation phase of the incident response lifecycle, organizations focus on establishing readiness before any incident occurs. Managing Cloud principles explain that preparation includes identifying potential threats, evaluating vulnerabilities, and assessing risks that could impact cloud operations.

Risk assessments are a core activity in this phase because they help organizations understand which assets are most critical, what threats are likely, and where controls must be strengthened. Performing risk assessments allows security teams to define incident response procedures, allocate resources, establish escalation paths, and ensure tools and personnel are prepared.

The other options occur in later phases. Taking systems offline is part of containment, estimating the scope of the incident occurs during detection and analysis, and building a timeline of attack supports post-incident analysis. Therefore, performing risk assessments is the correct countermeasure during the preparation phase.

When a management console is breached, the entire infrastructure managed by the control plane is at risk. Managing Cloud guidance explains that the management console provides administrative access to cloud resources such as virtual machines, networks, storage, and identity services.

A compromise of this interface allows attackers to create, modify, or delete resources, escalate privileges, access sensitive data, and disrupt operations across the entire cloud environment. Because the management console controls provisioning and configuration, its compromise represents a critical security failure.

The other options represent limited risks, but none match the broad impact of losing control over the management plane. Therefore, the correct answer is the entire infrastructure administered by the control plane.

Rapid elasticity is the cloud computing characteristic that allows consumers to automatically expand or contract resources based on demand. Managing Cloud documentation explains that rapid elasticity enables scaling of computing resources in near real time.

This capability allows organizations to handle variable workloads efficiently without manual intervention. Resources can be provisioned when demand increases and released when demand decreases, optimizing performance and cost.

Measured service focuses on usage tracking, resource pooling shares infrastructure, and on-demand self-service enables user provisioning. Therefore, rapid elasticity is the correct answer.

GDPR requires a demonstration of an adequate level of data protection equivalent to GDPR standards for cross-border data transfers. Managing Cloud guidance explains that personal data may only be transferred outside the EU/EEA if the receiving country or entity ensures appropriate safeguards.

These safeguards may include adequacy decisions, standard contractual clauses, or binding corporate rules. The goal is to ensure that personal data continues to receive the same level of protection regardless of where it is processed.

Formal consent alone is insufficient, and liability is not transferred exclusively to one party. Therefore, demonstrating adequate protection is the correct requirement.

Continuous auditing in the context of Information Rights Management (IRM) allows organizations to monitor access events in real time. It records who accessed a file, when, and how often. This enables organizations to enforce accountability and detect unusual access patterns, which are crucial for both security monitoring and compliance reporting.

Automatic expiration sets a time limit on file availability, while dynamic policy control adjusts permissions based on context (such as location or device). Persistent protection ensures files remain encrypted and controlled wherever they travel. While each feature is valuable, only continuous auditing provides the tracking and visibility into usage required by the scenario.

This approach aligns with governance requirements, providing an audit trail that supports incident response and compliance with data protection regulations. Continuous auditing strengthens both operational security and accountability.

Industry best practice requires that encryption keys are stored separately from the data they protect. This ensures that if the data storage system is compromised, attackers cannot immediately decrypt sensitive information. The use of a secure escrow system is a recognized approach.

An escrow provides controlled storage for encryption keys, ensuring they are only accessible by authorized processes and not co-located with the protected data. Keeping keys “local” to the data creates a single point of failure. A public or private repository without specialized protection mechanisms would also be insufficient due to risks of insider threats or misconfiguration.

By placing keys in an independent escrow system, the organization enforces separation of duties, strengthens defense-in-depth, and aligns with cryptographic standards from NIST and ISO. This practice is vital when dealing with archival data, where long-term confidentiality must be preserved even as systems evolve.

In a Software as a Service (SaaS) environment, the cloud service provider (CSP) is responsible for securing the platform. Managing Cloud principles explain that SaaS places the majority of security responsibilities on the provider, including infrastructure, operating systems, middleware, and application security.

Customers primarily manage user access, data usage, and configuration settings, while the provider ensures availability, patching, vulnerability management, and platform protection. This division of responsibility simplifies security management for consumers.

The other options misrepresent shared responsibility boundaries. In IaaS, customers secure the platform, and in PaaS, providers manage infrastructure. Therefore, option D accurately characterizes application movement to the cloud.

A Web Application Firewall (WAF) includes anti-distributed denial of service (DDoS) capabilities designed to protect cloud-hosted applications and underlying data storage from availability-based attacks. Managing Cloud principles state that WAFs sit in front of web applications and analyze incoming traffic to identify and block malicious requests, including high-volume attack patterns characteristic of DDoS attacks.

By filtering traffic at the application layer, a WAF prevents excessive or malicious requests from overwhelming backend services such as cloud storage systems and databases. Many WAF solutions implement rate limiting, traffic profiling, and behavioral analysis to distinguish legitimate users from attackers, ensuring continued access to cloud resources.

The other options do not provide DDoS protection. An XML gateway focuses on validating and securing XML-based messages. NDAM and ADAM solutions monitor database activity but do not mitigate network-level or application-layer flood attacks. Therefore, the Web Application Firewall is the correct security device for providing anti-DDoS protection in cloud environments.

Persistent protection is the security strategy most closely associated with data rights management (DRM) solutions. Managing Cloud principles explain that DRM is designed to ensure that data remains protected throughout its entire lifecycle, regardless of where it is stored, shared, or accessed.

Persistent protection means that security controls such as access restrictions, usage limitations, and expiration rules stay attached to the data itself. Even if the data is copied, transferred, or moved outside the original system, DRM policies continue to enforce protection. This approach is critical in cloud environments where data frequently moves across platforms, users, and geographic regions.

The other options do not represent DRM strategies. Multilevel aggregation and enhanced detail relate to data processing or analytics concepts, while unexpired digital content describes a content state rather than a security strategy. Therefore, persistent protection correctly represents the security approach used by data rights management solutions.
