A firewall is an example of a security device that can assist you in protecting your network and device from outside threats.
FREMONT, CA: Similar to how a fence protects your home and deters intruders, firewalls are used to secure a computer network. Firewalls are network security systems that block illegal network access. It can be hardware or software that filters the incoming and outgoing traffic within a private network based on rules designed to detect and prevent cyberattacks.
Firewalls are utilized in both business and home environments. They are a crucial element of network security. The majority of operating systems have a simple firewall. However, third-party firewall software offers superior protection.
As previously said, firewalls filter network traffic within private networks. Based on a set of rules, it determines which types of traffic should be permitted or prohibited. Consider the firewall to be a guard guarding your computer's network entrance, allowing only trustworthy sources or IP addresses to enter.
A firewall only accepts incoming traffic that has been set to be permitted. It differentiates between legitimate and malicious traffic and permits or blocks specific data packets based on predefined security rules.
These criteria are based on several features of the packet data, such as its source, destination, and content. To avoid cyberattacks, they block traffic from suspected sources.
For instance, the graphic below demonstrates how a firewall allows only authorized traffic to enter a user's private network.
