Firewall configuration management and its importance

A firewall plays an essential role in network security and must be configured correctly to protect organizations from data leakage and cyberattacks. The firewall can be kept secure by configuring policies and rules. Firewall policy configuration is based on network type, such as public or private, and can be configured with security rules that block or allow access to thwart potential hacker and malware attacks.

But when you try to install a firewall yourself, it’s never easy. You could run into many problems, like not being able to find the right firewall, setting up firewall policies that are too restrictive, using non-standard authentication methods, leaving ports open, using risky management services, and not having enough firewall monitoring. When this happens, the best way to get a firewall set up in your business is to use firewall installation services. Let’s talk about how to install a firewall in your business and what the benefits are of having someone else do it.

What is Firewall Configuration?

Firewalls are an integral component of any business’s security strategy. A firewall is designed to prevent the spread of viruses and unauthorized access to your network. 

There is a firewall between your computer and the internet. It determines which services on your computer are accessible to external network users. Monitoring network traffic and blocking suspected harmful traffic helps protect against cyber assaults, data exfiltration, and other risks.

A set of predetermined rules or policies is one of the primary ways firewalls determine whether a connection should be permitted or denied. Firewall installation and configuration refers to the process of configuring the rules and other security settings of a firewall. 

You must keep the following points in mind while firewall installation listed below:

  • Firewall Placement (Correct place to deploy in the network)
  • Configuring Network Parameters for Optimal Performance
  • Security Policies and Access Controls for better Security
  • Logging and Reporting for Compliance Requirements
  • Firewall Configuration Management
  • Pilot Configuration Test

Importance of Professional Firewall Installation

The rapid development of hybrid clouds, coupled with their increasingly widespread use, is outpacing the capabilities of network security to keep up. An increasing number of companies are attempting to protect themselves by utilizing network firewalls, which raises the possibility of configuration errors and policy holes. 

The configuration of these rules determines whether a firewall efficiently prevents malicious network connections or mistakenly inhibits legitimate business communications. In addition, if a firewall is not properly configured and protected, cyber threat actors may exploit vulnerabilities and security flaws to access the firewall and the protected network.

According to Gartner, until 2023, 99 percent of firewall breaches will be the result of firewall misconfigurations rather than technical flaws. Incorrect configuration of a firewall may allow unauthorized access to secure internal networks and resources. Organizations must ensure that the basic firewall configuration meets the needs of their networks and regulatory compliances.

How To Install a Firewall

A software firewall controls traffic via port numbers and programs. In contrast, a concrete firewall is a piece of hardware located among your network and gateway.

Next-generation firewalls (NGFW)

An average network security appliance NGFW combines packet inspection with stateful inspection, as well as some form of packet sniffing (DPI), and other network security tools such as IDS/IPS, malware filtering, and antivirus.

Application-level gateway

The single point of entry and exit for the network is this form of device, which is technically a proxy and also is referred to as a proxy firewall. Application-level gateways filter packets based on a variety of factors, such as the HTTP request string, in addition to the service for which they are meant, as indicated by the destination port.

Packet Filtering Firewall

At intersections where equipment like routers and switches operate, packet filtering firewalls operate inline. These firewalls don’t route packets; instead, they check each one against a list of predetermined standards such as the permitted IP addresses, packet type, port number, and other information from the packet protocol headers.

Stateful multilayer inspection (SMLI) firewalls

State-aware devices track whether a packet is a part of an active TCP or other network sessions in addition to inspecting each packet. While providing better security than either circuit monitoring or packet filtering by themselves, this has a bigger negative impact on network performance.

How does a Firewall Protect Data?

Firewalls can assist in avoiding a variety of security threats by establishing protective filters across your network and devices. These can include the following:


While some apps are meant to be accessed remotely, others may contain defects that allow potential hackers to get access to and abuse the program for malevolent reasons via a “backdoor,” or a concealed mechanism to access and exploit the Software. 

Denial of service

This increasingly common sort of malware can cause a server to slow down or crash. Hackers use this approach by sending a request to access the server, which responds with an acknowledgment and tries to connect.


Macros are programs that may be performed by programs to combine several complex operations into a single executable rule. If a hacker gains access to your customers’ devices, they can use the programs to execute their macros.

Remote logins

Remote logins range in intensity, but they always pertain to someone connecting to your computer and manipulating it. They can be a beneficial tool for allowing IT experts to swiftly upgrade something on a particular device without having to be physically there, but they can also be exploited by bad actors to get access to sensitive information or even run malicious applications.

Importance and Benefits of Firewall

Companies must pay attention to securing their networks from external dangers as much of the corporate sector continues to be digital. A firewall is one approach to defend the systems from external attacks. But, as the circumstances change, so should our strategies for defending our businesses. The Next Generation Firewall (NGFW) is the most recent form of digital security, combining the most remarkable aspects of classic technology with cutting-edge technology to deliver the best possible digital security.

The benefits of a Firewall are as follows:

1. Monitor network traffic

The flow of data into and out of your system may jeopardize the creation of operational possibilities. The firewall protects your system by monitoring and analyzing network traffic and applying pre-set rules and filters. 

2. Prevent virus attacks

A viral assault is the fastest way to bring your digital business to a halt. Every day, lots of new threats emerge, necessitating the implementation of suitable defensive measures to maintain the system healthy. 

3. Prevent hacking

Firewalls have become increasingly crucial as the number of data stolen and computer hijacking by criminals has increased, since they may prevent hackers from gaining unauthorized access to data, emails, systems, and other information.

4. Stop spyware

Preventing malware from obtaining access and infecting your system is a much-needed advantage in today’s data-driven society. Criminals will be able to get access to your system through more entry points as technologies become more complicated and powerful.

What Mistakes Organizations do After Purchasing Firewall

A firewall should be installed in every organization – it’s a vital component of network architecture, and it’s hard to establish efficient security protection without one.

A firewall, on the other hand, must be supplemented by specific firewall policies and processes that are owned and maintained by a professional. Your firewall is more likely to fail if you don’t take this extra step, leaving your network vulnerable to hackers, viruses, and other harmful traffic. Misconfiguration, not technology flaws, is to blame for 95% of all firewall breaches. This indicates that a firewall’s specs are inaccurate due to human mistakes or a lack of investigation.
