Assignment Cyber Security Week 4

QUESTIONS

  1. Explain the role of a firewall in protecting a business’s internal network.
  2. Why is it critical for employees working remotely to use a VPN?
  3. What is Wi-Fi encryption (like WPA2/WPA3), and why should a business never use an open, unsecured Wi-Fi network?

ANSWER NO.1

  1. Firewall is a network security system that acts as a barrier between a company’s internal network and external networks (the internet). Its functions include:
  • Controlling data traffic: A firewall monitors incoming and outgoing data and only allows data that is safe and follows the security rules.
  • Blocking unauthorized access: It prevents unauthorized people or external devices from accessing the company’s network and data.
  • Protecting against malware and cyberattacks: A firewall can help stop threats such as viruses, worms, and network-based attacks like DDoS.
  • Setting security policies: Administrators can create rules, such as limiting who can access certain websites or applications.
  • Protecting sensitive data: Firewalls help keep important company information safe, such as customer data, trade secrets, and internal documents.

In conclusion, a firewall acts as the main protective barrier that secures a company’s internal network from external threats, helping ensure that business activities run smoothly without disruption.

ANSWER NO.2

  1. VPN (Virtual Private Network) makes internet connections secure

When employees work from home or public places, all data sent to the company network is encrypted, so it cannot be easily stolen or intercepted.

 Only authorized employees can access the network

VPN ensures that only authorized users can access the company’s system.

Hackers or unauthorized outsiders cannot enter the network, even if they know the company’s IP address.

Safe when using public Wi-Fi

Wi-Fi networks in cafés, airports, or hotels are often not well protected.

By using a VPN, the internet connection remains secure and the employee’s data stays protected.

Protecting online privacy

VPN hides the employee’s IP address and location.

This helps prevent outsiders from tracking or monitoring internet activity.

In conclusion, using a VPN is important to protect company data, allow secure access to the company network, and maintain the privacy of remote employees, so they can work safely from anywhere.

ANSWER NO.3

  1. Wi-Fi encryption is a security technology used to protect a Wi-Fi network by using a password and converting data into a coded form that is difficult for unauthorized people to read. Examples include WPA2 and WPA3, which make the data sent through a Wi-Fi network more secure and unreadable to unauthorized users.

Why businesses should not use open Wi-Fi :

  •  Data can be easily stolen
    Without encryption, information such as passwords, email addresses, and customer data can be read or stolen by others.
  •  Strangers can access the network
    Anyone can connect to an open Wi-Fi network and try to access the company’s systems or files.
  • Higher risk of cyberattacks
    Hackers may install viruses or malware on devices connected to the network.
  • Threat to company security
    Important information such as business documents, financial reports, and customer data could be exposed.

In conclusion, Wi-Fi encryption such as WPA2 or WPA3 makes the network more secure and protected. Therefore, businesses should avoid using open and unsecured Wi-Fi networks.
