What is the main purpose of a host-based firewall?

• A. To safeguard internet connections
• B. To secure an individual device from attacks
• C. To improve internet performance
• D. To provide a user interface for remote connections

Answer: (B)

The main purpose of a host-based firewall is to secure an individual device from attacks. A host-based firewall operates at the device level, monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. This means it can effectively manage the security of a specific computer or server, allowing only authorized traffic and blocking potentially malicious connections. It provides an essential layer of defense by protecting the host from threats such as malware, unauthorized access, and various cyber attacks that could compromise the system and the data it holds. By focusing on safeguarding the device itself, host-based firewalls play a critical role in maintaining the integrity and confidentiality of individual systems within a larger network framework.
