Cisco Cyber Security Practice Exam

A malicious attack can lead to system failures affecting data availability. True or False?

1. True

2. False

3. Only in rare cases

4. False, it mostly affects hardware

The correct answer is: True

The assertion is true because a malicious attack, such as a Distributed Denial of Service (DDoS) attack or a ransomware attack, can significantly disrupt a system's ability to provide data availability. DDoS attacks overwhelm a system with traffic, making it impossible for legitimate users to access services. Ransomware encrypts data, rendering it inaccessible until a ransom is paid. These attacks can result in downtime, data loss, or significant delays in accessing critical information, ultimately affecting an organization’s operations. Data availability is a fundamental aspect of cybersecurity, and maintaining it is crucial for business continuity. A malicious attack can compromise not just the data's confidentiality or integrity but also its availability, impacting the overall effectiveness of an organization.
