CompTIA Security+ SY0-701 Updated Exam

Firmware is a type of software that is embedded in a hardware device, such as a router, a printer, or a BIOS chip. Firmware controls the basic functions and operations of the device, and it can be updated or modified by the manufacturer or the user. Firmware version is a hardware-specific vulnerability, as it can expose the device to security risks if it is outdated, corrupted, or tampered with. An attacker can exploit firmware vulnerabilities to gain unauthorized access, modify device settings, install malware, or cause damage to the device or the network. Therefore, it is important to keep firmware updated and verify its integrity and authenticity. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 2, page 67.

Comprehensive and Detailed Explanation From Exact Extract:

A responsibility matrix, often referred to in cloud computing as the Shared Responsibility Model, defines the exact roles, duties, and expectations between a cloud service provider (CSP) and the customer. This includes who is responsible for configuration, maintenance, patching, logging, updates, identity management, network security, and data protection.

According to the SY0-701 exam objectives, cloud models such as SaaS, PaaS, and IaaS all divide responsibilities differently. The responsibility matrix clarifies these boundaries so that neither party assumes the other is handling a critical security task. Misunderstandings in these areas can create dangerous security gaps, such as unpatched virtual machines, misconfigured storage buckets, or weak access controls.

A Service-Level Agreement (A) focuses on uptime, performance, and service expectations—not shared security roles. A Memorandum of Understanding (C) describes high-level cooperation between organizations, while an NDA (D) protects confidential information.

The responsibility matrix is emphasized under Security Program Management, specifically in managing third-party relationships and cloud provider governance, ensuring both parties understand their obligations and reducing the risk of misconfigurations or operational vulnerabilities.
