Firewalls Questions
The main difference between a firewall and antivirus software is their primary function and scope of protection.
A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between an internal network and the external network (usually the internet), allowing or blocking specific types of traffic based on the configured rules. Firewalls primarily focus on preventing unauthorized access to a network and protecting it from external threats such as hackers, malware, and unauthorized data transfers.
On the other hand, antivirus software is designed to detect, prevent, and remove malicious software (viruses, worms, Trojans, etc.) from a computer system. It scans files, programs, and the overall system for known patterns or signatures of malware, and if detected, it takes appropriate actions to neutralize or quarantine the threat. Antivirus software primarily focuses on protecting the computer system from malware infections and ensuring the integrity of files and data stored on the system.
In summary, while firewalls primarily protect networks by controlling traffic flow and preventing unauthorized access, antivirus software focuses on detecting and removing malware from computer systems. Both are essential components of a comprehensive security strategy and often work together to provide layered protection.
