- Explain the role of a firewall in protecting a business’s internal network.
- Why is it critical for employees working remotely to use a VPN?
- What is Wi-Fi encryption (like WPA2/WPA3), and why should a business never use an open, unsecured Wi-Fi network?
1. Role of a firewall
A firewall is a system that controls traffic between a company’s internal network and the internet.
What it does:
- Checks incoming and outgoing data
- Blocks suspicious or unauthorized access
- Allows only trusted connections based on rules
Why it matters:
- Stops hackers from entering the network
- Reduces risk of malware spreading
- Controls what systems and users can access
In short:
A firewall works like a filter or gate that only lets safe traffic pass through.
2. Why remote employees need a VPN
A VPN creates a secure and encrypted connection between a remote user and the company network.
Why it is important:
- Protects data when using public or home Wi-Fi
- Prevents attackers from intercepting information
- Keeps company systems secure even outside the office
Without a VPN:
- Data can be exposed or stolen
- Login credentials can be intercepted
In short:
A VPN keeps remote work secure by protecting data while it travels over the internet.
3. Wi-Fi encryption (WPA2/WPA3) and open network risks
Wi-Fi encryption (WPA2/WPA3) protects wireless communication by encoding data so only authorized users can read it.
- WPA2: strong and commonly used
- WPA3: newer and more secure
Why it matters:
- Keeps sensitive data private
- Prevents unauthorized access
Why businesses should avoid open Wi-Fi
Open Wi-Fi networks have no encryption, which means:
- Data can be easily intercepted
- Attackers can monitor or alter communication
- Users are exposed to security risks
Business impact:
- Data leaks
- Account compromise
- Loss of confidentiality
