What is a cyber attack?

• A. A legitimate access request by users
• B. An attempt to harm a computer system or network
• C. A process of hardware installation
• D. A measure of software security

Answer: (B)

A cyber attack is defined as an attempt to harm a computer system or network. This can involve various malicious activities, such as stealing data, disrupting services, or gaining unauthorized access to sensitive information. Cyber attacks can take many forms, including viruses, malware, ransomware, phishing, and denial-of-service attacks, among others. They are driven by various motives, including financial gain, political agendas, or simply the desire to cause disruption.

The correct identification of a cyber attack as harmful emphasizes the danger posed by malicious actors seeking to exploit vulnerabilities in systems and networks. It highlights the importance of cybersecurity measures to protect against potential threats.

In contrast, the other options describe scenarios that are not associated with the intent or nature of a cyber attack. A legitimate access request by users pertains to authorized interaction with systems, which does not involve malicious intent. The process of hardware installation relates to setting up physical components of computers and networks, while measures of software security refer to the protocols or tools designed to safeguard systems but do not describe an attack scenario. Understanding these distinctions is key to recognizing what constitutes a cyber attack.
