Future Scope of Firewall and its Primary Functions

Scope of Firewall

If you’re looking to get into the world of Firewalls, you’re in for a treat. In this blog, we’ll take a look at the scope of Firewall certification and what you can expect from it. Whether you’re a beginner or a seasoned pro, there’s something for everyone in this post. So without further ado, let’s take a look at the world of Firewalls! “Everything requires security,” that’s a very basic statement, but has a deep impact on the tech world. Everything of paramount importance needs security.  The network we have today is vital. Hence, its security is also equally important. Let’s now understand the security procedure of
various Networks. 

How do we Facilitate the Security needed? This is done by the Firewalls.

What are Firewalls?

As the literal word, walls suggests, provide protection. Similarly, firewalls provide protection to a system from unauthorized intrusive agents. 

Firewalls are meant to provide protection against any kind of outside cyber attacks by shielding the system or the given network from malicious or unnecessary network traffic. Firewalls are also meant to prevent malicious software from accessing a system or network via the internet.  

At the most basic level, a firewall is a necessary barrier between a private internal network and the public internet.

Why do we need Firewalls:

Did you know, that 60% of businesses close within 6 months of a Cyber-Attacks?

The need for firewalls is massive and it’s important to understand this need so as to be able to process the scope of the firewalls. 

The best and most efficient firewall is the one that is managed and reduces risk to businesses, enterprises and even individuals. Without the availability of a firewall, the systems can easily fall prey to a cyber attack causing the loss of data that is important. This loss of any kind of disturbance can cause disruption in any business process and that is supposed to reduce productivity. This can also cause a loss in the reputation of a particular brand. 

To manage Cybercrimes:

Cyber crimes can be avoided with the help of firewalls. Without the firewalls, the hackers can penetrate the system and gain access to all the important files, and data and also can deposit the data. They can also remove or mishandle the information. 

The potential threat is that there can be a huge financial loss, reputational damage and fines from authorities. 

A properly managed firewall can protect and maintain a network, data and devices. The users need to ensure that the firewall they choose is not going to compromise security. An efficient IT support partner will ensure a configured and managed firewall and all security updates are taken care of.
The benefits of a secure and managed firewall are numerous as it not only provides efficient service but also reduces capital investment and expenditure. 

Importance of Firewalls:

There are multiple reasons to choose firewalls few of them are listed below:

1.  Monitoring Network Traffic :

Firewall security begins with monitoring of network traffic based on pre-established rules.
The monitoring is inclusive of the following security measures. 

A. Source or destination-based blocking of incoming network traffic.

B. Outgoing network traffic can be blocked based on the source destination. 

C. Block network based on content.

D. Report on network traffic and firewall activities 

2. Stopping Virus Attacks and Spyware :

Each passing day the threats posed by cyber thieves seem to increase. The number of entry points that can be exploited to get access to a system that is growing as it keeps on growing more complicated. These firewalls act as the most crucial line of defence against malicious software. A lot of unwelcomed persons can gain access and steal data by penetrating into a network. 

3. Preventing Hacks: 

The threats in cyberspace are ever evolving and also spreading at a pace like no other. Firewalls tend to keep the hackers out of the systems and directly out of the data, emails and also out of other sensitive information.  

4. Promotes Privacy: 

Firewalls are a way of keeping the data safe and building an environment that ensures absolute safety and also building trust. Whereas a system without a firewall is unsafe as it accepts every connection to the system. Hence malicious users can penetrate into the system and mess with the data, emails etc and the safety shall be compromised. With the availability of a firewall, the threats can be detected and needed measures can be taken to deter away these malicious users.

Limitations of Firewall:

We have gone through the need and the benefits of firewalls. As each side has two aspects, similarly Firewalls also have limitations along with numerous benefits. Let’s have a look at the limitations firewall pose: 

  1. A firewall is incompetent in preventing attacks from attackers with modems from dailing into the system.
  2. Firewalls are also not eligible in preventing the misuse of passwords. The password policy is crucial as it will outline the guidelines for acceptable behaviour. 
  3. Firewalls have been found to be ineffective against nontechnical security risks such as social engineering. 
  4. Firewalls are futile in prohibiting internal users from accessing websites with flimsy code making user education critical.
  5. Firewalls are also impotent if the users’ security policy is too poor or relaxed or hasn’t been revised. 

The Overall Scope of the Firewall:

The scope in the field of firewalls is vast and growing at an alarming pace. Firewalls are as it is are a huge demand, since data is the new age currency and its safety is prime. Any candidate willing to go into this field has a bright chance as the remuneration is pretty hefty for each role. 

The market is in need of a lot of certified professionals and there is scarcity as well. A qualified professional is paid smartly. Considering the longevity of the certification, this profession is also a good one as the need is never going to fade out. The futuristic aspect of the profession is also bright. A firewall is a way of advancement in the security of all internet-related things. 

The need will never fade as security is going to be in need at all times, the progressive networking can be only aided by the efficiency that is introduced by the security. Hence the scope of firewalls is huge in simple words. The most important aspect is that the need is never going to die out, as far as the reports suggest. So anyone thinking of going for firewalls certification and entering the security domain has a bright future ahead of him.
