A playbook is a documented set of procedures that outlines the step-by-step response to specific types of cybersecurity incidents. Security Operations Centers (SOCs) use playbooks to improve consistency, efficiency, and accuracy during incident response. Playbooks help ensure that thecorrect procedures are followed based on the type of incident, ensuring swift and effective remediation.

Frameworks provide general guidelines for implementing security but are not specific enough for incident response procedures.

Baselines represent normal system behavior and are used for anomaly detection, not incident response guidance.

Benchmarks are performance standards and are not directly related to incident response​​.

Detailed Explanation:A VM escape occurs when an attacker breaks out of a virtual machine's isolation to access the hypervisor. This compromise can allow control of the hypervisor and all other VMs on the host, posing significant security risks. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "Virtualization Risks and Mitigation"​​.

Implementing playbooks as part of a SOAR (Security Orchestration, Automation, and Response) platform enables the automation of routine security tasks and the standardized response to common alerts. Playbooks help filter and validate alerts, reducing the number of false positives that analysts need to manually investigate. SOAR tools are specifically designed to improve efficiency, consistency, and accuracy in incident response, allowing analysts to focus on genuine threats rather than being overwhelmed by noise.

The scenario indicates that a user downloaded an unofficial patch, applied it, and afterward system files changed—detected by FIM. This strongly suggests the presence of a rootkit, which is designed to deeply embed itself into the operating system, altering core system files, modifying kernels, and hiding its presence.

Rootkits commonly replace or modify OS-level files, which results in changed file hashes—exactly what FIM is detecting. Rootkits often gain privileged, persistent control and are frequently disguised as legitimate updates or patches.

A logic bomb (A) is triggered by an event but does not typically modify OS files. A keylogger (B) captures keystrokes but doesn’t modify system files broadly. Ransomware (C) encrypts files, not silently alters system components.

Thus, the best match is D: Rootkit.

Hashing (C)is aone-way cryptographic functionthat produces afixed-length digestrepresenting the original data. If the file changes—even by one bit—the hash will change, making it ideal for verifyingdata integrity.

While encryption protectsconfidentiality, and masking/obfuscation protectdata visibility, onlyhashing ensures integrity.

Using two different cloud solutions to store data is an example of platform diversity, which helps reduce dependency on a single cloud provider and enhances resilience against vendor-specific failures or outages.

Load balancing (A) distributes workloads across resources; parallel processing (B) refers to simultaneous processing of tasks; clustering (D) involves grouping servers to act as a single system.

Platform diversity is a recognized architectural strategy to improve availability and fault tolerance, covered in Security Architecture concepts for SY0-701【6:Chapter 10†CompTIA Security+ Study Guide】
