What are the key components of a secure network?

• Antivirus software, weak passwords, open network access

• Outdated hardware, lack of employee training, no data backups

• Firewalls, encryption, strong authentication, intrusion detection systems, and regular security updates

• Public Wi-Fi, sharing passwords, using unsecured websites

Explain the concept of firewall and its role in network security.

• A firewall is a software used to enhance the speed of network traffic by bypassing security protocols.

• A firewall is a physical barrier installed around the network to prevent unauthorized access.

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

• A firewall is a type of computer virus that spreads through the network and compromises security.

What is data encryption and why is it important in cyber security?

• Data encryption is the process of converting data into a physical form. It is important in cyber security to make data more accessible.

• Data encryption is the process of converting data into a code to prevent unauthorized access. It is important in cyber security to protect sensitive information from being intercepted or accessed by hackers.

• Data encryption is the process of converting data into a code to make it harder to read. It is important in cyber security to confuse users.
