Throwing a spanner in the works of cyberpunks that persistently try to gain unauthorized access to the private data, Firewalls are the security officers in the first line of defense in the army of Network Security Systems.

Protecting the network by monitoring and controlling the incoming and outgoing network traffic based on predefined security rules, A firewall can be categorized as a hardware firewall that is stored between network and gateway, for example, broadband router and a software firewall that is a software program working through ports and number of applications. Holding the power to analyze the traffic and immediately block the unwanted traffic from untrusted sources, Firewalls protect the system from hackers and malicious software. This security tool that examines the data coming to the network in the form of packets can provide better security and increased privacy.

With firewalls pre-installed in operating systems and security software to secure sensitive information from increased sophisticated cyberattacks in the digital world, can the periodic database update of firewalls combat the unobserved Malwares?
