In our modern times it is commonplace to perform the majority of our work and other tasks on the internet, such as online education and shopping online, among others.

Tasks that would have taken hours to complete are accomplished today with the help of computers, laptops and smartphones, all connected to the internet.

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

To prevent these online activities firewall software is employed to act as a security barrier against illicit and unauthorised access using laptops, computers or tablet, smartphone, etc.

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

In simple terms, firewalls are designed to guard and safeguard sensitive personal information information from spammers, hackers crackers, malwares, and viruses.

What exactly is Firewall?

Firewalls are the layers of protection of computers, which are designed to shield computer systems from insecure users or programs that could be malware, viruses and other malware.

They also aid in securing our system against malware and hackers..

Modern routers that are used in computer networking , where laptops and other computers are linked to each other to perform 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 systems on networks when malware and viruses attack.

The routers can also prevent malicious programs or codes from being able to access the computer network. They also aid to protect the computer from malicious and dangerous programs.

It has been observed that when one computer is affected by malware or viruses and routers block the virus from spreading to other computers in the network.

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 our computers from unauthorised access and viruses, malicious programs and hackers.

The malicious programs get into our system and steal vital data, such as IDs or passwords, credit card and debit card information, and then use them to harm us personally and financial losses.

Additionally, with these unwelcome codes, security at stake.

It is observed that when installing new games or software, the firewall displays an alert box which indicates that it’s inquiring consent to run the application or game.

In addition, many of the games or programs are not allowed to run because the firewall is aware of security issues, and therefore does its best to prevent 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 major benefit of using 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 delivered in packets.

A firewall aids in identifying and determining if there is any potentially dangerous software or code that is in the packet.

If the firewall gets to discover that the packets have been damaged and are contaminated by malicious software, it will block future access for the packets.

#2. Protection against viruses.

The firewall has been constructed and designed to ensure that they serve as a security barrier and shield from our computers and unwanted software.

They also have a security feature that activates when they come into contact with such software and files.

The programs or software’s via the virus’s attempt to spread its virus to other computers within the network are stopped and removed from the network by the firewall.

#3. Protection from Hackers.

Hardware routers are more than capable of dealing with spammers and hackers due to their quiet feature.

They also increase your security firewall that filters packets. Thus, they offer the best protection against hackers.

#4. Easy Installation.

The installation procedure of software firewalls is simple and is done without the help of a specialist.

Additionally, there are tutorials on the web which can assist in understanding the entire process thoroughly.

Modern operating systems such as Windows 7, Windows 8, Windows 10 come with built-in firewalls.

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

#5. Protect yourself from Malware.

Certain malware may be present in 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

They can be misused in the form of personal and financial loss.

This malware is sophisticated enough that it cannot be easily detected, therefore the firewall should be installed in order to provide a reasonable amount of security against such malware such as trojan horses.

Trojan Horses is a malicious program developed, designed in a planned and executed manner to cause harm to computers.

The codes are crafted so that when it comes into contact with another software or document, it alters them to the Trojan virus.

#6. Grouping.

The functions in a firewall can be organized and are therefore managed similarly to the management of bandwidth or content filtering or another security features.

They are then grouped and rules are applied.

#7. Virtual Connectivity.

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

So, users can be connected to the web at any time , thus it is possible to say the virtual connection is feasible.

#8. Improved Security.

With the use of modern routers and firewalls, the security of your home has improved dramatically and

Computer systems aren’t likely to be hacked or infected this easily compared to earlier years.

The firewall is made up of multiple layers of security that are difficult to break because the hardware and software and software update themselves to safeguard from threats and unauthorized access.

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

The majority of systems 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

It is true that this software firewall will be less expensive and includes the most up-to-date and most up-to-date operating systems, including Windows 7, Windows 8, Windows 10, and Windows 10.2.

Certain software firewalls are also equipped with antivirus software that is premium. But, the hardware firewall can be somewhat expensive contrasted with other options.

firewalls, it also offers many protections from malware and hackers. To install this firewall on hardware, expert assistance and guidance is required.

#2. Performance

It has been discovered that the firewall software limits computers’ performance.

They typically use system resources and memory resources of RAM (Random Access Memory) that do not permit the system to operate at the full capacity.

The high use of memory is evident in the slow speeds and slow performance of the system. This could be because the firewall runs in the background without knowing.

#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 improve the virus database definition, but most of the instances it is observed that they have let some malware pass unnoticed.

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

#4. Maintenance

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

regularly check the latest policies and incorporate them into the system. The old policies must be considered.

5 Internal Network Attacks

They are extremely difficult to detect and can be very tedious since the perpetrator has access to the internal system.

So the firewalls aren’t equipped to recognize these sources that have authorized credentials to gain access to the system.

The firewalls are created and created to protect against attacks that come from outside of the network, as well as other sources, and therefore cannot handle incidents that happen within the networks.

#6. Firewall Removal

When software-based firewalls are installed, some crucial files are incorporated into the

operating system kernel and dll file and therefore when we try to eliminate these firewalls, they are unable to eliminate all of them from our operating system.

#7. False Firewall

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

Furthermore, they don’t safeguard or protect our system against malware, viruses and hackers.

Different types of Firewall

Firewalls can be classified into various kinds that I have described below.

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