Using the equation risk = probability x consequence what is a cyber threat?
The correct answer and explanation is:
Correct Answer:
A cyber threat is a potential risk of malicious activity that aims to damage, disrupt, or gain unauthorized access to computer systems, networks, or digital data. Using the equation Risk = Probability × Consequence, a cyber threat is an event where the probability of a cyberattack and the consequences of its success determine the overall risk to an organization or individual.
300-Word Explanation:
The concept of risk in cybersecurity can be expressed with the formula:
Risk = Probability × Consequence
In this context:
- Probability is the likelihood that a cyberattack (such as malware, phishing, ransomware, or hacking) will occur.
- Consequence refers to the impact if the attack succeeds—this could include data loss, financial damage, service disruption, reputation harm, or even legal consequences.
A cyber threat refers to any possible danger that exploits a vulnerability to breach security and cause harm. This can come from hackers, cybercriminals, insiders, or nation-state actors. Examples include:
- Phishing emails that trick users into revealing passwords.
- Ransomware that locks files and demands payment.
- Denial-of-service (DoS) attacks that shut down websites.
- Data breaches leaking personal or corporate information.
Using the formula, organizations evaluate the risk posed by each threat. For example, if a phishing attack has a high probability (employees are frequently targeted) and high consequence (it could lead to a major data breach), then the risk is high. Conversely, a threat with low likelihood and low impact poses minimal risk.
Understanding cyber threats through this equation helps prioritize defense strategies. Organizations focus on reducing probability (e.g., by using firewalls, training staff) and minimizing consequences (e.g., by having backups, encryption, and incident response plans).
Thus, a cyber threat becomes a measurable risk when evaluated using the formula, guiding smarter cybersecurity investments and policies.
