Understanding Cyber Security Features

Cyber security is a critical aspect of protecting digital systems, networks, and data from malicious attacks. It involves a set of technologies, processes, and practices designed to protect programs, networks, and data from unauthorized access or damage.

Let's look at the features mentioned in the options and how they relate to cyber security:

Compliance in Cyber Security

Compliance refers to adhering to laws, regulations, standards, and policies related to data protection and information security. Various industries and governments have specific rules (like GDPR, HIPAA, PCI DSS) that organizations must follow to protect sensitive data. Cyber security measures are essential to meet these compliance requirements, avoiding legal penalties and building trust.

Defence Against Internal Threats

Cyber threats don't just come from outside an organization. Internal threats, which originate from within the organization (employees, contractors, etc.), can be accidental or malicious. A robust cyber security strategy includes measures to detect, prevent, and respond to threats posed by insiders. This involves access controls, monitoring user activity, and security awareness training.

Threat Prevention

A primary goal of cyber security is to prevent threats from occurring in the first place. This includes implementing measures like firewalls, intrusion prevention systems, antivirus software, secure coding practices, and regular security updates to stop attacks before they can cause harm.

Conclusion on Cyber Security Features

Based on the analysis:

• Compliance is a key requirement that cyber security helps achieve.
• Defending against internal threats is a vital part of a comprehensive cyber security strategy.
• Threat prevention is a fundamental objective and function of cyber security measures.

Since all three points listed in options 1, 2, and 3 are indeed features or critical components of cyber security, the option that includes all of them is the most accurate answer.
