What is a common method used in phishing attacks to trick individuals into providing sensitive information?

• Bogus text messages

• Phony phone calls

• Deceptive emails

• Fake websites

What is the purpose of a firewall in cybersecurity?

• The purpose of a firewall is to increase vulnerability to cyber attacks

• The purpose of a firewall in cybersecurity is to monitor and control network traffic to protect against unauthorized access and cyber attacks.

• A firewall is used to enhance internet speed

• Firewalls are designed to create network congestion

How can malware detection software help protect a computer system?

• By providing access to sensitive information to hackers

• By slowing down the computer system performance

• By making the computer system more vulnerable to attacks

• By scanning for malware signatures, behavior patterns, and anomalies, as well as providing real-time protection.

Explain the concept of data encryption and its importance in cybersecurity.

• Data encryption is only necessary for non-sensitive information.

• Data encryption involves encoding data using algorithms to make it unreadable without the correct decryption key. This helps in safeguarding data during transmission and storage, reducing the risk of data breaches and unauthorized access.

• Data encryption is a process of compressing data to save storage space.

• Data encryption involves converting data into images for security purposes.

What are some common measures to enhance network security?

• Never update software

• Use the same password for all accounts

• Share sensitive information openly

• Implement strong passwords, use firewalls, keep software up to date, encrypt data, use VPNs, and conduct regular security audits.

What is social engineering in the context of cybersecurity?

• Using firewalls to prevent unauthorized access

• Installing antivirus software on all devices

• Encrypting sensitive data to protect it from hackers

• Manipulation of individuals to divulge confidential information or compromise security.

How can individuals identify a phishing email?

• Provide personal information immediately

• Check sender email addresses, verify links, look for errors, avoid providing personal information

• Click on all links in the email

• Ignore all emails

What are the different types of firewalls and their functionalities?

• Packet filtering, Proxy, Stateful inspection, Next-generation

• Firewall filtering, Application firewall, Cloud-based firewall

Why is it important to regularly update antivirus software for malware detection?

• To have the latest virus definitions and security patches for effective malware detection.

• To slow down the computer system

• To increase the risk of malware infection

• To save storage space on the device

Describe the process of encrypting data using asymmetric encryption.

• The recipient's public key is used for decryption

• The process involves using the same key for encryption and decryption

• The data is encrypted using the sender's private key

• The process of encrypting data using asymmetric encryption involves generating a key pair, encrypting the data with the recipient's public key, and decrypting it with the recipient's private key.
