A firewall is usually a generic network security device that manages and controls outgoing and incoming network traffic according to predefined security criteria. A firewall normally establishes a barrier between an untrusted remote network and a trusted local network, like the Internet. Firewalls prevent unauthorized access by controlling the communication between two or more networks.
There are many factors that determine firewalls security requirements. One of these is the type of network that the firewall is used for managing. Another factor that greatly influences the firewall’s security requirements is the types of information that need to be managed or protected. Other firewalls security requirements may include the performance of the firewall, the integrity of the firewall, the performance of the network that the firewall manages, and any other specific needs that may be required by the organization.

To meet these needs, companies that specialize in Internet security have developed the next-generation firewalls. Today’s firewall designs address several concerns that traditionally hindered the design of effective firewalls. Traditional firewalls were slow to implement, susceptible to hacking, and required complicated configuration or initiation processes. Newer firewalls are much faster and allow for simple configuration, making them easy to use by even a novice IT professional. In addition, newer firewalls have been designed to protect against malware threats and to improve security for corporate data.
Types of Firewall
There are three basic types of Firewall applications that businesses use to protect their information & critical systems from malicious external elements to prevent destructive elements from accessing the network, namely Packet Filter, Stateful Inspection & Proxy server Firewalls. However, each application has several aspects & utilities which are vital for running efficiently. For instance, a firewall is necessary to restrict access to your network and all the computers on it. A thorough evaluation of your current setup is essential before implementing any type of firewall to ensure that all your necessary components are functioning properly.
The three main types of firewalls are – layer 1 – packet filter, layer 2 – stateful firewall and layer 3 – gateway protection. The first layer of the firewall filters the packets that enter your network. These packets contain sensitive information like credit card numbers, website login information and anything else which can be exploited by a hacker. Firewalls usually run on software interface which is set up as per your requirements.
One of the most popular types of Firewall applications is the Cloud Firewall. With the help of this firewall, you can secure your business applications and information across multiple servers and departments without installing any additional hardware. In addition to that, the cloud security suite detects the unauthorized entry and blocks the malicious content from entering the network. This firewall appliance consists of several components like – Policy enforcement, Alert Management, Prevention and Security Management, Detection capability and Information Protection.
On the other hand, an intruder detection firewall is also essential for protecting your network from the hackers who use the Web browser and other online tools to infiltrate your corporate network. It can be configured with simple rules that block or allow specific types of web traffic. Apart from blocking the malicious traffic, it can also block all the standard network traffic. The best part about this firewall is that it has high levels of security and can be automatically scheduled.
Another very popular type of Firewall application is packet-filtering. With the help of this application you can protect your network from the unauthorized or harmful access of data packets. It can be configured to control the different types of Internet activity and is mostly used with the types of packet-filtering software like Small Business Protection (SBP), Fair Accurate Protection (FAP) and Family of Choice (FCP).
Another very important type of Firewall is the security device. These devices perform the task of filtering outgoing traffic based on the IP addresses. They can be either point-to-point or blanketed. Point-to-Point Firewall devices do not allow the blocking of specific ports to the blanketed types allow the port blocking based on the source IP address and the destination IP address. The advantage of using these types of security device is that they are very reliable and provide effective protection against hackers. They are mostly used in companies where high level of security is required.
Why do you need a firewall?
A firewall is also responsible for maintaining the security of your network. Without this program, your network is prone to attacks from different parts of the world that can break into your computer and access your files and personal information. The most basic components of a firewall include a firewall, a filtering device, and a router. There are more advanced types of firewalls designed to block malicious programs, hackers, and even Trojans. These advanced types of firewalls are often referred to as content filters.
Many companies make the decision to purchase and install a company-wide firewall within their network. For companies with a smaller staff, a firewall can often be overlooked until it is too late. As a result, an entire business can be put on hold because of a single issue related to the firewall.
