Why Do Firewalls Are Crucial For Network Security

1. Why Do Firewalls Are Crucial For Network Security? Types of firewall network security and benefits Firewall is one of the key security measures deployed to provide safety of the network within an organization. It is essentially the barrier between the external network, the internet and the company’s internal network. By definition, a firewall is a device installed between an external network and an internal network that controls the incoming and outgoing data through a set of rules coded by the network administrator. At Techno Edge Systems, we provide firewall network security as a part of the Managed IT services we offer for small and large companies. Types of firewall network security The job of the firewall installed is to process only the relevant traffic through the network and filter out all the unnecessary traffic. The firewall is one or a combination of the following methods to ensure utmost network security. Packet filtering: pre-determined rules evaluate the packets of information, their source, and destination, and flag any inappropriate packets accordingly. Stateful Inspection: Stateful Inspection is the next-level firewall network security method, where the packets of information are investigated to identify if the data belongs to the existing connection. If found, that the data is not a part of the existing connection, the call is taken as per the defined rules of the firewall.

2. Application Filtering: This network security method was introduced in 1999 and stops malware or malicious websites from entering the network by understanding various protocols, such as HTTP, FTP, and DNS. This method filters the packets of information until the application layer. Proxy Service: The proxy is the intermediary between the internal network and the external connection. The proxy basically ensures that there is not a direct connection between both the networks. As the network traffic passes through the middle layer, the unwarranted entities are filtered out. Benefits of using firewall network security systems Monitors: Firewalls monitor closely all incoming and outgoing network traffic and stop all irrelevant data from entering the network. Blocks potential threats and malware: Firewalls prevent potentially harmful programs like malware and viruses from entering the company's network. Protects Sensitive Data: The firewall also protects the network infrastructure within the organization. It stops hackers from stealing sensitive information like passwords, bank information by identifying suspicious connections. However, it is crucial that you have your firewalls installed by professionals to ensure the safety of your company's network. Properly established firewalls are hard to penetrate, providing fool proof protection from invaders from outside and within the organization.
