Detailed Solution
Download Solution PDFThe correct answer is Option 2) To monitor and control incoming and outgoing network traffic.
Key Points
- A firewall is a network security system that monitors and filters incoming and outgoing network traffic based on predetermined security rules.
- Its main function is to act as a barrier between a trusted internal network and untrusted external networks (such as the internet).
- Firewalls help prevent unauthorized access, data breaches, and cyberattacks.
Additional Information
- Option 1 – Speeding up internet: Not a firewall function; this is managed by network optimization tools.
- Option 3 – Storing data securely: Done by storage and encryption tools, not firewalls.
- Option 4 – Detecting and removing viruses: This is the role of antivirus software, not firewalls.
- Firewalls can be hardware-based, software-based, or both, and are essential for maintaining network security.
