CompTIA CS0-002 Questions Answers

According to the CompTIA CySA+ Certification Exam (CS0-002) study guide, a tabletop exercise can be executed by internal managers to simulate and validate changes to the risk management plan, incident response plan, and system security plan. In a tabletop exercise, participants discuss and work through a simulated scenario, usually in a classroom or conference room setting, to evaluate their readiness and understanding of the proposed changes. This type of exercise can help to identify any potential issues or gaps in the proposed changes and can provide valuable insights for refining and improving the plans.

Reporting processes are important to include when updating an incident response plan after a breach for several reasons. Two of the most likely reasons are:

• To meet regulatory requirements for timely reporting. Many regulations and standards require organizations to report security incidents or breaches within a certain time frame or face penalties or sanctions. For example, the General Data Protection Regulation (GDPR) requires organizations to report personal data breaches within 72 hours of becoming aware of them. Reporting processes can help organizations to comply with these requirements by defining who, what, when, where, how, and why to report incidents or breaches.
• To limit reputation damage caused by the breach. Security incidents or breaches can have negative impacts on an organization’s reputation, trust, and customer loyalty. Reporting processes can help organizations to limit these impacts by communicating effectively and transparently with internal and external stakeholders, such as employees, customers, partners, regulators, media, and public. Reporting processes can help organizations to provide accurate and consistent information about the breach, its causes, impacts, and remediation actions.

Other possible reasons to include reporting processes when updating an incident response plan after a breach are:

• To establish a clear chain of command (A). Reporting processes can help organizations to establish a clear chain of command for incident response by defining roles and responsibilities, escalation procedures, and decision-making authority.
• To remediate vulnerabilities that led to the breach (D). Reporting processes can help organizations to remediate vulnerabilities that led to the breach by documenting and analyzing the root causes, lessons learned, and best practices for improvement.
• To isolate potential insider threats (E). Reporting processes can help organizations to isolate potential insider threats by monitoring and auditing user activities, behaviors, and access rights before, during, and after the breach.

CAN bus (Controller Area Network) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other’s applications without a host computer1. CAN bus is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper, but it can also be used in many other contexts. CAN bus enables each device to send and receive data on a shared network, reducing the need for complex wiring and increasing reliability and performance. CAN bus is one of the five protocols used in the on-board diagnostics (OBD)-II vehicle diagnostics standard. A vulnerability within the new fleet of vehicles that the company recently purchased is most likely targeting CAN bus, as it is a common and critical communication system in modern vehicles. An attacker could exploit a vulnerability in CAN bus to compromise or manipulate various vehicle functions or systems, such as braking, steering, engine control, airbags, etc. SCADA (A) stands for Supervisory Control And Data Acquisition, which is a system that monitors and controls industrial processes or infrastructure2. SCADA is not a vehicle bus standard and is not likely to be targeted by a vulnerability within a fleet of vehicles. Modbus © is a serial communications protocol that connects industrial electronic devices3. Modbus is not a vehicle bus standard and is not likely to be targeted by a vulnerability within a fleet of vehicles. IoT (D) stands for Internet of Things, which is a network of physical objects that are embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the internet. IoT is not a vehicle bus standard and is not likely to be targeted by a vulnerability within a fleet of vehicles.

A breach notification is a communication to affected individuals or entities that informs them of a security incident involving their personal or sensitive information. A breach notification may include details such as what information was compromised, when and how the incident occurred, what actions are being taken to mitigate the impact, and what steps the recipients should take to protect themselves3 A breach notification may be required by law or regulation, depending on the type and location of the information involved and the jurisdiction of the affected parties. Different countries or regions may have different breach notification requirements, such as who must be notified, when, how, and what information must be disclosed4 Therefore, the best role to determine the breach notification requirements for a company that experienced a breach of sensitive information affecting customers across multiple geographical regions is legal counsel. Legal counsel can advise the company on its legal obligations and liabilities, as well as help draft and deliver appropriate breach notifications.
