Q & A

What is the definition of cyber security?

Cyber security is the practice of protecting computer systems, networks, electronic devices, and programs from cyber attacks that aim to access, alter, or destroy sensitive user information and disrupt business operations.

What is the CIA Triad in cyber security?

The CIA Triad refers to three key principles in cyber security: Confidentiality (ensuring only authorized individuals can access data), Integrity (ensuring the information is accurate and unaltered), and Availability (ensuring information is accessible when needed).

What is the importance of authorization, authentication, and non-repudiation in cyber security?

Authorization ensures individuals have appropriate access rights to information, authentication confirms the identity of users (e.g., through passwords), and non-repudiation ensures individuals cannot deny their actions (e.g., sending an email with a proof of action).

How did cyber security originate and evolve over time?

The origin of cyber security can be traced back to 1971 with the development of the Creeper virus, followed by the Reaper antivirus. Over time, cyber security evolved as more sophisticated threats emerged, leading to the development of various protective measures, practices, and software.

Why is cyber security essential in today's digital world?

Cyber security is essential because it protects sensitive data, such as personal details, financial data, and private communications, from malicious attacks. It ensures that systems and networks remain secure and that data integrity and privacy are maintained.

Can you give some examples of real-world cyber security incidents?

Examples of real-world cyber incidents include the WannaCry ransomware attack, Yahoo's 2014 data breach, the Adobe cyber attack, and the PlayStation Network attack, where personal data was stolen, and business operations were disrupted.

What are some core principles involved in cyber security?

Core principles in cyber security include protecting networks and devices from unauthorized access, ensuring data confidentiality and integrity, managing identities and access, and responding effectively to cyber incidents.

What are some common types of cyber security threats?

Common cyber security threats include malware attacks (viruses, worms, ransomware), phishing scams (emails, SMS, voice calls), denial of service attacks, SQL injections, and zero-day exploits.

What role do ethical hackers and penetration testers play in cyber security?

Ethical hackers and penetration testers identify and fix vulnerabilities in systems before malicious hackers can exploit them. They simulate attacks to uncover weaknesses, helping to secure systems and protect against future threats.

What strategies can individuals use to enhance their cyber security?

Individuals can enhance their cyber security by using strong passwords, enabling two-factor authentication, practicing safe internet habits, backing up data regularly, adjusting privacy settings, and educating themselves about common cyber threats.

What strategies should organizations implement to improve their cyber security?

Organizations should establish strong password policies, use multi-factor authentication, ensure regular software updates, monitor security logs, deploy firewalls and intrusion detection systems, and have a disaster recovery plan in place.
