Exploring Cybersecurity and Data Mining

What is the primary goal of cybersecurity?

• To enhance user experience on websites.

• To develop new software applications.

• To protect systems, networks, and data from cyber threats.

• To increase the speed of internet connections.

Define data mining in the context of cybersecurity.

• Data mining in cybersecurity is solely focused on data storage and management.

• Data mining in cybersecurity involves creating firewalls to block unauthorized access.

• Data mining in cybersecurity is the process of encrypting sensitive data.

• Data mining in cybersecurity is the process of analyzing data to identify patterns and detect potential security threats.

What are common types of cyber threats?

• firewall breaches

• malware, phishing, ransomware, denial-of-service attacks, man-in-the-middle attacks

• data encryption

• spam emails

Explain the concept of phishing.

• Phishing is a method of securing sensitive information through encryption.

• Phishing refers to the process of fishing for data in a database.

• Phishing is a legitimate marketing strategy used by companies to gather customer feedback.

• Phishing is a fraudulent attempt to obtain sensitive information by pretending to be a trustworthy source.

What role does encryption play in data security?

• Encryption makes data accessible to all users.

• Encryption speeds up data transfer between users.

• Encryption is used to compress data for storage.

• Encryption secures data by making it unreadable to unauthorized users, ensuring confidentiality and integrity.

What is a firewall and how does it work?

• A firewall is a network security device that monitors and controls network traffic based on security rules.

• A firewall is a type of antivirus software that removes malware from devices.

• A firewall is a physical barrier that prevents unauthorized access to buildings.

• A firewall is a device that boosts internet speed by compressing data.

Describe the term 'malware' and its types.

• Malware is malicious software designed to harm or exploit devices and networks, with types including viruses, worms, trojans, ransomware, spyware, adware, and rootkits.

• Malware is a type of hardware used for computer repairs.

• Malware is a legal software used for data protection.

• Malware refers to software that enhances device performance.

What is the significance of a strong password?

• A strong password protects against unauthorized access and reduces the risk of identity theft.

• A strong password guarantees complete online security.

• A strong password can be easily remembered without any effort.

• A strong password is only necessary for online shopping.

How can social engineering be used in cybercrime?

• Social engineering helps in creating stronger passwords.

• Social engineering can be used in cybercrime to manipulate individuals into revealing sensitive information or performing actions that compromise security.

• Social engineering is used to enhance cybersecurity measures.

• Social engineering is a method for improving user awareness about phishing.

What is the difference between a virus and a worm?

• A virus needs a host and user action to spread; a worm is self-replicating and spreads automatically.

• A virus is a type of worm that spreads through email.

• Both viruses and worms need user action to spread.
