Understanding Cyber Security Concepts

What is the primary goal of cyber security?

• To increase the speed of internet connections.

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

• To enhance user experience on digital platforms.

• To promote social media engagement.

Define the term 'malware'.

• Malware is a legal term for software licensing.

• Malware is malicious software intended to damage or disrupt systems.

• Malware refers to software that enhances system performance.

• Malware is a type of hardware used for computing.

What is a firewall and how does it work?

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

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

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

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

Explain the concept of phishing.

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

• Phishing is a technique used to enhance online security by verifying user identities.

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

• Phishing refers to the process of creating strong passwords for online accounts.

What is the difference between symmetric and asymmetric encryption?

• Symmetric encryption uses one key for both encryption and decryption, while asymmetric encryption uses a pair of keys (public and private) for these processes.

• Asymmetric encryption is faster than symmetric encryption for all types of data.

• Symmetric encryption is only used for digital signatures.

• Symmetric encryption uses two keys for encryption and decryption.

What role do antivirus programs play in cyber security?

• Antivirus programs only enhance internet speed.

• Antivirus programs primarily manage user passwords.

• Antivirus programs are used to create firewalls.

• Antivirus programs detect, prevent, and remove malware, enhancing cyber security.

What is a DDoS attack?

• A DDoS attack is a security measure to protect against unauthorized access.

• A DDoS attack is a method to enhance service performance by distributing traffic.

• A DDoS attack is a type of software used for data encryption.

• A DDoS attack is a malicious attempt to disrupt a service by overwhelming it with traffic from multiple sources.

How can strong passwords enhance security?

• Strong passwords are only necessary for online banking.

• Weak passwords can be easily guessed by anyone.

• Strong passwords are easy to remember and share.

• Strong passwords make it harder for attackers to gain unauthorized access.

What is social engineering in the context of cyber security?

• A technique for encrypting sensitive data during transmission.

• A method to enhance network security by training employees.

• Social engineering is the manipulation of individuals to obtain confidential information for fraudulent purposes.

• A process for creating strong passwords to protect accounts.

Why is it important to keep software updated?
