In the modern age it is commonplace to perform most of our work and activities online via the internet, such as online education shopping online, for example.

The jobs that took hours to complete are completed in a matter of minutes using computers, laptops or smartphones connected to the internet.

It’s been noticed that the usage of the internet has dramatically increased and the risks associated with internet use have also has increased such as hacking, hacking spamming, hacking, etc.

To prevent these online activities firewalls are employed to act as a barrier to unauthorised and illegal access using laptops, computers or tablet, smartphone, and so on.

In this article I’ll talk about 7 Benefits and disadvantages of Firewall and the benefits and drawbacks associated with Firewall as well as the advantages and disadvantages of employing Firewall with illustrations and examples.

In simple terms, firewall software is designed to guard and safeguard your sensitive and personal data Information from spammers, hackers crackers, malwares, and viruses.

What exactly is Firewall?

Firewalls are the security layers of computers. They help protect computer systems from insecure users or software that may include malware, viruses, malware, etc.

They also aid in securing our system against hackers and other malicious programs..

Modern routers that are used in computer networking , where laptops and other computers are linked to facilitate transfers of data and data exchange.

The routers come with a firewall that is activated during configuration and assists in preventing the system from being infected by other computers on the network when malware and viruses attack.

The routers also block undesirable programs or code from being able to access the computer network. They assist to protect the computer from harmful malicious programs.

It is known that if one computer is affected by malware or viruses and routers block that virus from spreading and infecting other computers in the network.

Now let’s discuss the second firewall, which can be described as the firewall software.

Firewalls are included in all modern operating systems such as Windows 7, Windows 8, Windows 10, etc.

They protect the computer system from unauthorised access and viruses, malicious programs as well as hackers.

These malware-infested programs infiltrate our system and steal crucial data such as ID or passwords, credit card or debit card details, and then use them to harm us personally and financial losses.

In addition, these codes, privacy at risk.

It is observed that when we install new games or software, the firewall displays dialog boxes that indicate that it is seeking consent to run the program or game.

Additionally, often some of the games or programs are not allowed to run since the firewall is aware of security risks, so it will take preventive measures to stay clear of these threats.

Let’s discuss some of the advantages and advantages of firewalls in the form of points.

Traffic Monitoring
Protection from Virus.
Protection from Hackers.
Easy Installation.
Protect yourself from Malware.
Grouping.
Virtual Connectivity.
Improved Security.

#1. Traffic Monitoring.

The primary benefit of having firewalls is that they can monitor and measure all traffic going through it.

Information or data that is passing through or through the network comes as packets.

A firewall assists in determining and checking whether there is any potentially dangerous software or code that is that is attached to the.

If the firewall gets to discover that the packets have been damaged and are contaminated by malware, it stops future access for the packets.

#2. Protection from Virus.

The firewall has been created and designed so that they serve as a protection wall and a shield against our system’s computer and unwanted software.

They come with a security function which is activated whenever they come into contact with these software and files.

The programs or software’s via which the virus tries to infect other computers on the network are stopped and removed through the firewall.

#3. Safety from Hackers.

Hardware routers are more adept at dealing with spammers and hackers due to their quiet feature.

They also improve your security firewalls that filter packets. They also provide the ultimate security against hackers.

#4. Easy Installation.

The process of installing software firewalls is easy and can be completed without the assistance of a professional.

Additionally, there are tutorials on the web that can help you understand the entire process thoroughly.

Modern Operating Systems like Windows 7, Windows 8, Windows 10 come with built-in firewalls.

However, the firewall on the hardware is not easy to install and maintain. To access them, it is recommended to seek professional guidance.

#5. Security against Malware.

Some malware may reside within the system of computers unintentionally and replicate itself many times.

This malware is able to steal all of the crucial information and data from your system , and then

Use them to the detriment of personal and financial loss.

The malware is clever enough that it cannot be easily detected, therefore the firewall should be set up to offer a good amount of protection from malware such as trojan horses.

Trojan Horses is a malicious program that was designed, developed by planning, designing, and constructing to cause harm to your computer.

The codes are crafted so that when they interact with any other software or document, it alters them to the Trojan virus.

#6. Grouping.

The functions in a firewall can be combined and thus controlled as content filtering, bandwidth management or another security features.

They are then grouped and guidelines are put in place for them.

#7. Virtual Connectivity.

The routers are connected to other networks via the aid by LAN (Local Area Network[LAN].

So, users can access the Internet at any moment, therefore it is said it is feasible.

#8. Improved Security.

With the use of modern routers and firewalls, the security of the network has increased dramatically and

Computer systems aren’t prone to be hacked or infected this easily compared to the past.

The firewall is made up of multiple layers of security that are not as easy to circumvent since the software and hardware and software update themselves to safeguard against unauthorized access and threats.

They have been extremely efficient in neutralizing viruses or malware as well as hacking attacks, and

The majority of the system nowadays is focused on firewall security because of its advantages and benefits firewalls.
Drawbacks and Advantages of Firewall

Cost
Performance
Malware Attacks
Performance is degraded
Maintenance
Internal Network Attacks
Firewall Removal
False Firewall

#1. Cost

There is no doubt that it is more affordable and includes the most up-to-date and up-to-date operating systems such as Windows 7, Windows 8, Windows 10, and Windows 10.2.

Certain software firewalls are also equipped with top antivirus software. The hardware firewalls are thought to be quite expensive it comes to other firewalls.

firewalls, it also offers many protections from malware and hackers. When installing this firewall on hardware, expert advice and assistance is needed.

#2. Performance

It was observed that software firewalls limit computers’ performance.

They usually use system resources as well as memory resources from RAM (Random Access Memory) that do not permit the system to function at its maximum efficiency.

The high use of memory is evident in the slow speeds and slow performance of the system, if it is discovered that this is because the firewall runs in the background, unintentionally.

#3. Malware Attacks

The software, and also the hardware-based firewalls, are insecure despite the fact that it is constantly evolving.

The firewall is regularly updated to update the virus database definition, but in the majority of cases , it’s been found that they have let some malware pass unnoticed.

Therefore , relying heavily on hardware- or software-based firewalls is not recommended.

#4. Maintenance

The hardware or software-based firewall is very challenging to maintain , as we are required to

Check the policies periodically and incorporate them into the system. The old policies must be considered.

5 Internal Network Attacks

They can be very difficult to spot and difficult to pinpoint since the perpetrator has access to the internal system.

So the firewalls aren’t equipped to recognize these sources with the appropriate credentials to gain access to the system.

The firewalls were designed and designed to stop attacks coming from outside the network, as well as other sources, and therefore are not able to handle attacks that occur within the networks.

#6. Firewall Removal

Although software-based firewalls are used, some important files integrate with the

operating system kernel and dll files , and therefore when we try to get rid of these firewalls, they will not remove these files completely off the operating system.

#7. False Firewall

There are some firewalls that use software on the market that promises many things, but when it comes to use Fails to meet their promises.

Additionally, they cannot ensure that our systems are protected from malware, viruses, and hackers.

Different types of Firewall

Firewalls can be classified into various kinds, which I have listed below.

Packet Filter Firewall
Stateless Packet Filter
Stateful Packet Filter
Application Level Gateway Firewall
Circuit-Level Gateway firewall
